How Do You Repair a Flat Roof?

damaged and worn flat roof

Keeping your flat roof at its best

The majority of commercial or industrial buildings are in large buildings that have expansive flat roofing. The roof of these structures is flat for a couple of reasons, one being it is less expensive to build and another reason, the HVAC system is installed on top of the structure.  With the HVAC on the roof, it leaves more real estate on the ground for parking, an important feature for a business. 

Unfortunately, this leaves the building open for some issues like the abuse flat roofing is susceptible to from the environment and weather. Because they are expansive and flat, they get more of the sun’s UV rays beating down on them. There is more area with flat roofing for hail, ice, rain, and snow to plummet, leaving behind damage. 

Flat roofing requires a different type roofing material that is durable and can hold up to the elements and environment. What is the best material for a flat roof?  That deciding factor must be made building by building because not all flat roofing materials are the same.

With several key factors for consideration, like the cost for installation and the material, the energy rating, maintenance requirements, and life expectancy, along with the aesthetics. The roofing application will determine which of the following flat roofing materials will work best for any commercial or industrial building. 

  • Modified Bitumen: This asphalt-based flat roofing material is modified using special polymers that enhance its performance and malleability. Arrives at the job site in rolls from the factor and has a finished surface that is either granulated or smooth. It can be installed in 3 different manners: cold-applied, heat-applied, or self-adhered. In general, this is the more costly flat roofing material and offers a lifespan up to twenty years, which is relatively short compared to other materials. It is an energy efficient roofing material that is fairly durable and can endure extreme temperatures while diminishing the heat on the roof surface. Locating a leak source can be difficult  with this flat roofing substrate.
  • Built-Up Roofs (BUR): Used on flat roofing surfaces for over than one hundred years, making it the most common type of material on commercial or industrial buildings. The name built-up comes from the several alternating layers of asphalt and reinforcing fabrics with a finishing top layer of an aggregate like gravel, mineral granules, or slag. This flat roofing material has an expected lifespan up to thirty years with little maintenance required. Provides excellent UV ray and waterproofing protection with the aggregate layer making it fire-resistant. An visually pleasing flat roofing material, it is the more expensive of materials that take more time for installing. It is not as resistant to water or wind damage as other flat roofing materials offer.
  • EPDM Rubber: This synthetic rubber compound is used on many low-slope flat roofing structures because of the versatility it provides, proving to be effective solution for many commercial or industrial structures. Most structures have it installed in black, but it is available in gray, tan, or white. A conformable, durable, impervious, and lightweight flat roofing material that has a life expectancy of 30 years or longer and is one of the less costly options in flat roofing materials. A relatively easy maintain material when compared to other commercial flat roofing materials, but because it is easy to puncture and has the tendency to shrink, it isn’t the best choice for every flat roofing commercial or industrial structure. With the popular choice of black roofing color, it isn’t as energy-efficient as the lighter color flat roofing materials. 
  • Single-Ply: PVC and TPO are single-ply membranes and are more common for commercial flat roofing materials. While they look similar, both are white, applied by heat welding, and are thermoplastic systems, they are different. The PVC, polyvinyl chloride, a durable flat roofing product with a 20 year lifespan is fire and water resistant and withstands heavy winds. Compared to EPDM and TPO flat roofing materials, is more expensive and punctures easily. The TPO, thermoplastic polyolefin, is a flexible flat roofing material that can last up to 25 years and is  less expensive than the PVC flat roofing material. It is easier to install and maintain but is a “younger” material that has only been around since the 1990s. 
  • Spray Polyurethane Foam: The least common of flat roofing material options but the most effective with a combination of closed-cell, plural-component, offers an insulation and protective elastomeric top-coating. With routine maintenance, it has a lifespan of more than 50 years with a superior insulation barrier that provides superior energy efficiency and R-value. A strong material that increases the integrity of commercial building structures but should only be installed by flat roofing  contractors that are experienced in spray foam installation. A lack of experience can affect the integrity of this commercial flat roofing material.

How many years does a flat roof last?

As we stated earlier, the type of flat roofing material you choose will have various lifespans. They range anywhere from as little as 10 years and up to 50 years or longer. Installation and maintenance are key factors in the longevity of any flat roofing materials. 

How do you stop a flat roof from leaking?

 Not the ideal situation, but you can perform flat roof repair in rain for a temporary stop. Schedule proper flat roofing repair as soon as the weather permits to keep any further damage from happening in the next rainstorm. 

Any debris and ponding water will need to be cleaned from the flat roofing surface before you can patch the roof to stop leaking. Using a silicone patching material and a dense brush, apply the silicone over the leak and if the leak is around or near flashing, coat the flashing too.  Then, once the silicone has dried,  apply a plastic tarp, held down by heavy boards or other objects.

Reminder that this should only be a temporary repair and a professional roofing contractor should be scheduled for installing a permeant flat roof repair or replacement once the weather permits. 

Can you patch a flat roof?

There are a few options to patching flat roofing: 

1) An EPDM rubber flat roofing can be patched with a DIY repair kit available from roofing supply stores. Included in the kit will be adhesive and tape for quick repairs. 

2) For patching and repairs, call a flat roofing expert contractor. This may cost you a few hundred dollars, but at the same time, could be saving you thousands. 

3) If your flat roofing is modified bitumen, you will need to call a professional flat roofing contractor due to the welding required. 

4) A tar and gravel flat roofing will be a challenge to find the leak source, even for the most experienced commercial roofing contractor. Many times, after an inspection, trial and error in finding the leak, a full replacement is recommended. 

5) For a flat roofing with single-ply membrane, you can have a coating applied, but expect it to need recoating or replacing within the next two to three years. This is an expensive solution and not long lasting.

How do you repair a flat roof?

While it may be easier to call a professional roofing contractor, a commercial property owner also knows the value of a dollar (or hundreds of dollars in this case). With the right equipment, supplies, tools, and some hands-on skills, minor flat roofing repairs are possible with these steps: 

  • Inspection: Locate the leak and determine what needs to be repaired. 
  • Clearance: Clear any debris and dry up any pools of water. Chances are those pooled areas is where you’ll find the leak(s).  Be sure to brush or sweep away all loose debris and obstructions. 
  • Blisters: Any blisters on your flat roofing should be removed by slicing them in the middle and raise the slices up to expose the roofing felt below. 
  • Water: Remove any water under the blister using rags and shop vacuum. Let the area dry completely before going forward. 
  • Cement: Fill in the area with roofing cement and spread the cement around the affected areas too. Even out an y areas that are unlevel and damaged. Do this with any cracks and holes as well. 
  • Membrane: Final step is installing a new layer of your flat roofing membrane while the roofing cement is still wet. Once in place, seal the edges with galvanized nails. 

If you need flat roof repair in wintertime, it is recommended to call a professional roofing contractor.  They will have the experience and safety gear to do the repair safely.

Do I need soffit and fascia?

Soffit & Fascia along roof

Parts of your home and roofing system

Your house has several structural components. Ceilings, flooring, walls, and a roof, and each of those things have components with them when they are constructed. Like the roof example, it has rafters, decking, shingles, and the soffit & fascia. Today, we’re going to discuss two of the components in the roof: the soffit & fascia.

Let’s start by discussing what do soffits and fascia do, because to the unknowing person, they may just seem like decorative parts to the roof. Both the soffits and fascia on a house have important functions for the roof.  

The soffits keep the attic ventilated so that moisture doesn’t build up in the attic and rot the rafters. The roll of the fascia is different but just as important in preventing damage and rot to the attic and roof by covering the ends of the rafters. With out the soffit & fascia, the roofing would go bad faster and need replacing way before the 20, 25, or 30 year warranty was expired on the shingles! 

Do I need to vent my soffits?

If you haven’t got the message yet, attic ventilation is important to the health of your roof and your home. One reason, for homes in warm climates and hot summers, you’ll have a cooler attic with soffit vents. They help keep your home cooler so that you need the air conditioning less.  In the winter, soffit vents keeps the moisture build up minimal by providing attic ventilation. This keeps the water condensation all but eliminated and that keeps mildew, mold, and rot away. 

When soffit & fascia are installed on a home, the soffit is typically an aluminum, vinyl, or wood. There is non-vented soffit and standard for homes with a narrow eave. There are two primary types of soffit vents, one is the continuous soffit vents. They are long and narrow vents running the entire length of the soffit and used for homes with narrow eaves. The other soffit vents is the more common and are individual vents that are cut to size when installed between the soffit joists.

Does roof replacement include fascia?

The original timing for soffits and fascia installation is during construction of the house. Then when the roof is replaced, usually 20 to 30 years later, the roofing contractor will inspect the soffit & fascia and determine if they need repairing, replacing, or can be left alone. While a roofing contractor can certainly replace the fascia & soffit while replacing the roof, if they only repairing, the contractor may sub that job to general handyman contractor.  

What goes on first fascia or soffit?

When deciding if the soffit and fascia or siding first, in most cases the fascia is installed first. This is the long straight piece that runs along the lower edge of the roof and is fastened to the trusses. The job of the fascia is to protect to support the bottom row of roofing material. The fascia board is also where the gutter runs are fastened.  

Next, the soffit board is positioned so that it tucks under the fascia board. When you are standing on the sidewalk, you see this as you look up at the roof. The fascia board protects the eaves and keeps things out of the attic. Without a fascia board, your attic would be open to all the critters and insects. 

Is it OK to pressure wash soffits and fascia?

Because of the importance the soffit & fascia are to your home, it is recommended to have your home, including the soffit and fascia cleaned by a professional service. They will have the proper equipment and tools with the experience on how to wash them without damage. 

fascia along roof

 How do you clean soffits and fascia?

However, if you choose to do this yourself, follow these tips:

  • Water Pressure: Use a low pressure setting. Hard setting can bust through the fascia board and into your attic. 
  • Make sure your ladder is firm and secure in place, climb with caution.
  • Wear rubber sole shoes with a good tread. 
  • Watch for falling debris as you wash.

As you can tell from our piece the soffit & fascia may appear to be nothing more than cosmetic features for your home. They are more than a place to fasten the gutter run and Christmas lights. They have a strong purpose and if you left them off your home for a week, you’d find out quickly why you need soffit & fascia on your home.

While your roofing material may have a 25 to 30-year lifespan, the soffit & fascia may need repairs or replacement earlier. They are just as important at the roof itself, so when you see any rot or sagging areas, call a professional contractor to for repairs or replacement.

Do roofers repair skylights?

open skylight

Wait a minute, can a skylight be repaired?

A skylight can give a room a completely different look, adding a dimension and bring in natural light. However, when there is damage to the roof from storms, a skylight is typically damaged as well. So, you’re left not only with roof repair, but skylight repair too, and fortunately, both can be accomplished with an experienced roofing contractor. 

With a skylight, you get more natural light, and your comfort and privacy aren’t compromised. When a skylight begins to leak though, how do you know that you need just  Skylight repair or replacement going to be required? Just how complicated and expensive is a skylight repair? 

Well, before you go into a panic and decide to have the skylight permanently covered up or removed, have an experienced roofing contractor inspect it first.  A roofing contractor that is experienced in skylight repair and installation will be able to give you advise and an estimate, even help you decide if permanently covering it up or removing it an option. 

A skylight that has a continuous leak usually indicates a damaged skylight. A skylight that has  condensation building up on the inside can  be results from the room, like a bathroom or kitchen. Sometimes, it can be an indication that skylight repair is needed. Some possible issues that cause a skylight to leak and require skylight glass repair:

  • Flashing Damage: Your chimney, exhaust pipes and skylight have metal flashing around them to prevent them from leaking. Because it exposed to the elements continuously, it can weaken and allow leaks. A professional roofing contractor with skylight experience can replace or repair skylight flashing and inspect the entire roof while up there. If the skylight flashing is corroded and worn, most likely flashing in other areas is too. 
  • Roofing Cement: A skylight that was installed and secured with roofing cement will likely begin to leak as the cement ages and cracks over time. Usually, there are tiny holes in the roofing cement and the skylight repair to stop the leak can removing the aged and cracked roof cement and applying new roofing cement. 
  • Poor Installation: Not all roofing contractors are experienced in installing a skylight or will take short cuts to stay under budget and on time. This often ends up with a leaking skylight, but that isn’t anything that a qualified roofing contractor can’t fix. The contractor will inspect the skylight and roofing around it, and will advise if skylight repair is possible, or possibly the only option is to replace the  skylight entirely.      

How do you repair a leaking skylight?

What appears to be a skylight leak may not be a leak, but condensation formed on the inside of the skylight. This is common during the winter or if the skylight is in the bathroom or kitchen where moisture is common. 

If you have confirmed the skylight does have a leak, you’ll need to clean the skylight from the rooftop. Remove any debris and limbs so that you can examine the skylight’s exterior and the flashing around it. If you don’t find anything obvious, use a water hose and run water over and all around the skylight to duplicate the possible leak. Once you have found the leak, you can do repairs yourself using one of these options: 

  • Reattach the flashing or seal up gaps and holes with roofing cement.
  • Apply silicone caulking around the skylight lens.
  • Replace the metal flashing.

If these don’t stop the leak, you’ll need to contact a professional roofing contractor that has skylight experience. 

How do you cover a broken skylight?

Missouri is in Tornado Alley, where severe weather is common during the spring and early summer. When you know that extreme weather is coming, you can protect your skylight by covering it with a blanket, boards, or a tarp. This will keep hail from directly hitting the skylight glass and minimize the possibility of needing skylight repair or replacement.

If you don’t have the opportunity to take preventive measures and your skylight is broken or damaged during a storm, you should have a professional roofing contractor inspect the skylight and roof. While waiting for the contractor, you can cover the skylight with a plastic tarp and use 2×4 boards to hold the tarp in place on top of the roof.  Once the repairs are made, have the contractor install a protective film that will protect the skylight going forward. 

Skylights in a room

Is A Skylight Worth Installing? 

Newer homes often have a skylight installed during construction, but an existing older home can have a skylight too.  Get several quotes from roofing contractors that are experienced with skylight installation, remember the best isn’t necessarily the most expensive and the cheapest quote, you may get what you pay for.  

So, with all the information we’ve provided here, you may wonder if a skylight is worthwhile. A common question is what is the life expectancy of a skylight? The typical lifespan of a skylight is around eight years. A skylight that was professional installed by an experienced contractor and is made of high quality glass can give you up to fifteen years of enjoyment.

How often does roof decking need to be replaced?

home with a roof decking in good condition

Roof decking under your materials

What’s up on the rooftop is one question, what is under the shingles, roof decking vs sheathing is another question. There are a many components to a roof, most of it we don’t see from the ground, like the roof decking. To understand your roof better, explaining what roof decking and other components are, we have a break down what is under the shingles: 

  • Trusses: The foundation of the roof, this creates the peak of your roof and provides support for the rest of the roofing components, especially the roof decking.
  • Chimney: If your home has a fireplace, it needs a chimney to carry the ash and soot from the fireplace out, so it doesn’t fill your home. 
  • Flashing: This metal strip is installed where different roof angles meet, around the chimney , and other areas that are prone to leak.  
  • Vent pipe: This small pipe extends up, allowing fresh air into the plumbing so that sinks, toilets, and tubs can drain. 
  • Sheathing: This is the subject of today’s article, sometimes referred to as the roof decking, and the first layer of the roof, and maybe called roof decking or sheathing. This will be either roof decking osb vs plywood and is attached to the trusses, creating the foundation for the shingles. 
  • Underlayment: This thin layer of material is attached to the sheathing, aka roof decking, is typically an asphalt coated felt, is the barrier from element and helps water to shed when a shingle is loose or missing, minimizing the chance of roof decking exposed. 
  • Shingles: This is the part you see and comes in several colors, styles,  and textures. 
  • Ridge Vent: This is at the peak of the roof, runs the entire length and keeps moisture from collecting in your attic and maintains a consistent temperature in the attic. 
  • Ridge cap: These are some shingles that cover the ridge vents and keep moisture out so the ridge vents can do their job. 
  • Fascia: This is the board you see running along the bottom of the roof trusses to keep things out of the attic and the elements blowing up under the roof decking.

What is better for a roof OSB or plywood?

When comes to choose between OSB or plywood for roof decking, both having structural characteristics, both rated Exposure 1 for temporary element exposure, and resistant to nail withdrawal, is one better than the other? It really becomes the builder’s or roofing contractor’s choice, with the following facts helping them make their decision. 

OSB, an engineered wood with particleboard like feel and look, is manufactured with strands of wood compressed together in specific orientation, unevenly, creating the rough surface you feel. It is available in different rigidity, sizes, strengths, and thickness.  It is a water-resistant material but does need the addition of an additional membrane to create complete water impermeability. 

OSB offers consistent density and doesn’t have knot holes other natural flaws that can create weak areas. A structural uniform product that is less expensive than plywood and has a stronger load-bearing capacity. 

Plywood has an advantage in stiffness, making the ideal material for subflooring, and is often used as roof decking with 24-inch truss spacing in 7/8-inch thickness. A higher quality material than OSB, and still dominates the market for many builders, contractors, and homeowners. 

What is the best option for roof decking?

When your builder or roofing contractor is choosing the roof decking for your home, they are choosing a material that they feel  will last for years, protecting your investment. In most cases, OSB has become the first choice. 

In 2006, almost 60% of all new houses had OSB for their roof decking. The intertwined and bonded wood strands provide optimal resistance to moisture, however, if water does work its way to the roof decking, OSB will rot faster than plywood. 

This reiterates why roof decking must be covered in quality roof felt and why regular inspections of the roof are important. Making sure there aren’t any missing shingles or flashing where water can penetrate to the roof decking. 

How thick should roof decking be?

Roof sheathing should always be nailed to the trusses, never stapled, using 8d ring-shank nails.  The roof sheathing itself should be no less than 19/32-inch thick and up to ¾ inch thick, the most common thickness. 

When a house is being built, the builder may choose to use roof decking with insulation, using a foam board insulation product. A homeowner can have a contactor install insulation  to the underside after the home is built as well, usually with a spray foam insulation material for ease. Other types of insulation like bat rolls and foam board aren’t as easily attached to the roof decking after construction is completed. 

How do I know if my roof decking is bad?

The roof of your complement the exterior and is also a layer of defense against the elements. Under the shingles that does all this is the roof decking. If the roof decking is compromised, your entire home is compromised Indications that your roof decking may be compromised are: 

  • Shingles buckling and curling.
  • Asphalt granules thin on the shingles.
  • Holes in the roofing.
  • Mildew or mold in the attic.
  • Loose or missing shingles.
  • Roof has spongy feel when contractor or inspector walk on the roof.
  • Damage found around the chimney, pipes, or other penetration.

Should I replace the plywood on my roof?

If you, a roofing contractor, or inspector find any of the things we just listed with your home’s roof, then yes, a roof decking replacement may be needed. An experienced roofing contractor can advise you if the entire roof decking needs replacing, or just certain areas. Either way, follow the advice after getting two to three estimates. The roof decking is what is protecting your home under the asphalt shingles. Need help with your roof and its decking in Chesterfield and St. Louis, MO? Call (314) 786-3732 today!

Is spray foam insulation worth it?

spray foam insulation

What homeowner isn’t conscious of their energy bills every month?

No matter if it is summer or winter, we are all turning things off to save money, or find a way to make things work more efficient, like the cooling and heating. With that mind, are you have you looked at having spray foam insulation added to your attic? 

Here, we have answered a few commonly ask questions about spray foam insulation, and hopefully that includes information to help you determine if this is the way you need to insulation your home. The first question is what are the pros and cons of spray foam insulation?

Spray Foam Insulation – The Pros

Industry experts recommend spray foam insulation in existing and new build homes. Considered to be high performing product, spray foam insulation provides an air barrier and vapor barrier while insulating your home, making your home more energy efficient so that your HVAC system doesn’t work as hard to cool or heat your home. Your electric and gas bills are lower because of this efficiency. Other benefits of spray foam insulation include: 

  • air leakage is essentially eliminated
  • heat loss is prevented
  • ideal insulation for attics, floors, roofs, walls
  • a higher R-Value other insulation materials  
  • reduced moisture accumulation
  • additional  vapor barrier not needed
  • seals up any awkward spaces 
  • effectively eradicates air drafts

Spray Foam Insulation – The Cons

There is only one con, but it something to be considered. Because spray foam insulation is a superior performing product in comparison to other insulation materials, the initial installation has a higher upfront cost that is often more than most homeowners have budgeted. While the ROI is great, it is achieved over a longer period of time.  

Other Insulation Materials: Fiberglass and Foam Board

When comparing spray foam insulation or fiberglass for your home, consider that fiberglass insulation is manufactured from glass fiber in either batt rolls or blown in loose fill. It does provide satisfactory capacity and is ore affordable for most homeowners, a DIY homeowner can do their own installation. Using it in the basement requires additional installation of vapor barrier, an additional expense that should be factored in the decision.

  Between spray foam insulation vs foam board, the following facts about foam board should be considered when choosing: 

  • Opportunity increased for penetrations because it is mechanically fastened
  • Decreased  flexibility due to rigidity format
  • When installed perfectly, provides the best air sealing and insulation
  • Increased install cost for time-consuming process
  • Often need addition of other form of  insulation to get the best results 

Should I spray foam my attic?

There isn’t any shortage of insulation products to choose from today, but the most recommended is spray foam insulation, contractors boast about the long-term and short-term benefits offered by this product when the open-cell form of spray foam insulation is used. While it is not a DIY insulation product, only installed by professional contractors with the proper equipment and training, it will have the biggest ROI over time in comparison to other types of insulation materials. 

Is it better to insulate attic ceiling or floor?

For your home to get the optimal energy efficiency, it needs to be insulated starting at the roof and to the floor. If your attic is unfinished, insulation should be placed between the floor joists and then over the floor joists, using an open-cell with spray foam insulation.  If the attic has air distribution, insulate the rafters as well. For a finished attic, insulation should be installed between the wall studs and exterior wall and roof rafters. The exterior walls, including the internal walls attached, unheated garage should be insulated. 

foam insulation application

Can you over insulate a house?

The purpose of spray foam insulation, or any insulation, is to make your home more efficient in cooling or heating by sealing the interior from the elements. However, it is possible to over-do the insulating to the point the house isn’t breathing. When a house can’t breathe, moisture is trapped inside the layers, creating the perfect place for mildew and mold to grow. 

When asked how long does spray foam insulation last, we can tell you that between spray foam insulation and mortgages, you’ll have your mortgage paid off long before you’ll need to reapply the spray foam insulation.  

The International Association of Certified Home Inspectors advises that spray foam insulation and wrap tape insulation have a life expectancy of eighty years or longer. Other types of insulation have a life expectancy of 100 years which includes, cellulose, foamboard, loose fill, and rock wool insulation materials. 

The number one concern for any homeowner when choosing an insulation material is the expense.  Spray foam insulation is the most expensive, but also will have a higher ROI over a longer period of time.  If you’re going to be in your house for years, then it is worth the investment.

What is the Best Roof Coating?

silicone roof coating

What is the Best Roof Coating?

Silicone roof coatings have made a big impact on the flat roof coating community. Silicone roof coatings arrive with a number of wonderful advantages and some disadvantages. However, it is important to consider which coating is best for your property. With regard to what is the best roof coating, let’s turn to the facts. According to numerous online websites, silicone roof coatings are considered the preferential choice when it comes to UV resistance as well as resistance to ponding water. These roof coatings are responsible for eroding much slower than other kinds of roof coatings and do not become brittle or hard as quickly either.

How Long Does it Take for Silicone Roof Coating to Dry?

If you are considering a new silicone roof coating application, it will be important for you to understand how long the process takes. According to a leading silicone roofing manufacturer, it takes approximately eight to twenty-four hours for a silicone roof coating to properly dry. This estimate depends on the prevailing weather conditions of the area. In locations where the weather is dewy and has high humidity, it will cause the silicone roof coating to take much longer to dry. On the other hand, if you live in an arid part of the country, and you apply the silicone on a particularly dry day, the silicone will dry faster.

Does Roof Coating Stop Leaks?

As any responsible roofer can attest, it will be important for all the lingering cracks and crevices of your roof to be properly repaired before a silicone roof coating is installed. Once a roofing company has been brought in to help out with your roof repairs, you can then discuss your brand-new roof coating. A silicone roof coating will improve your roof’s performance and increase its protection against inclement weather elements such as heavy rain, ponding water, damaging UV rays, and much more.

How Do You Clean Silicone Roof Coating?

Believe it or not, despite silicone roofs being quite durable, they pick up dirt and debris quite easily. That is why it is important for you to research the best ways for you to clean your silicone roof. Fortunately, silicone roofs can be effectively cleaned with a light pressure wash. When annual pressure washes are applied to the surface of your silicone roof, your roof will perform well for many years to come.

Can Silicone Stop Water Leaks?

It is important to recognize that silicone has many great qualities. For instance, it can hold standing water for long periods of time without degrading or leaking. However, if you are thinking of treating a roof repair with only silicone, be advised that there are better and more responsible ways to repair the area. The best person to call in such scenarios is a reputable and respectable roofing company.

Benefits of Silicone Roof Coating

Are you wondering what the benefits are for silicone roof coatings? If so, please review the following list to discover more.

  • Resistance to ponding water. Silicone roof coatings are capable of enduring the damaging effects of ponding water without breaking down. This is because of their composition. Silicone is a moisture-cure substance and that means that it will not absorb additional water after it has cured.
  • Great UV protection. Did you know that silicone roof coatings can reflect up to eighty to ninety percent of the sun’s harmful UV rays? For commercial property owners and operators, this can translate into meaningful energy savings during the summer.
  • Flexibility. Silicone roof coatings are indeed highly flexible, monolithic, and hard to permeate. These advantages are especially great for flat and low-slope roofs.

Is Silicone Roof Coating Worth It

If your roof system has not received the care and attention of roof repairs in recent years, it is very important for you to enlist a professional roofing company to carry out a roof inspection. A roof inspection will yield results concerning what exactly the current condition is. If roof repairs are in order, those must be done first before a silicone roof coating is considered. After all of your roof repairs have been completed and your silicone roof coating has been applied, you can breathe a sigh of relief because your roof will perform well in the face of inclement weather.

How Does Spray Foam Roofing Work?

spray foam roofing

Quality Roofing You Can Trust

What is spray foam roofing? This method of roofing has gained popularity in commercial structures due to its durability and ease of installation. The material that is used for spray foam roofing is a liquid form of polyurethane that expands as foam once it is sprayed. How does spray foam roofing work?  As it expands, it creates a solid layer, spreading across an existing roof. This SPF material can be used in any climate and on most roofing systems. With proper installation and maintenance, commercial spray foam roofing can have a life span of fifty years or more.

Why get spray foam roofing?

There are seven reasons why more commercial building owners are going with the spray foam roofing today: 

  • High R-Value: Of the different roof insulation options, the highest R-Value material is spray foam roofing of polyurethane foam. R-value is the capacity to resist heat flow. To get the most insulation power, you want a high R-value. You will see a total ROI within ten years through lower cooling and heating costs. 
  • Renewable: Spray foam roofing has several benefits starting with energy savings, as we just mentioned. Another benefit that is popular today, it is a renewable material when it has been installed correctly and is maintained as advised by the manufacturer and contractor. By renewable, we mean it can be re-coated without having to tear off any old roofing, keeping that material out of the landfills. A spray foam roofing re-coating will add another ten to twenty years to an existing roof. 
  • Quick Install: Spray foam roofing is quick to install because there is no tear-off of the existing roof. As spray foam roofing is installed, the foam forms around roof penetrations, and there isn’t any heavy equipment required for installation.
  • Self-Flashing: Spray foam roofing forms to irregular shapes that commercial structures are known to have, including forming to the curbs and creating flashings. It forms around penetrations like drains, HVAC units, skylights, parapet walls, pipes, and vents. 
  • Seamless: This may be one of the most significant benefits of spray foam roofing: It is seamless!  For a commercial building, this is a huge benefit because this means less chance of leaks. Seamless spray foam roofing is watertight and wind-resistant because there are no corners or edges lift and allow the wind to catch it or allow rain to get under the foam membrane.
  • Maintenance Ease: Commercial structures often have work done on the roof for the HVAC, electrical, plumbing, etc.  Accidents happen, and a contractor will drop a sharp tool that can tear the spray foam roofing material.  This is an easy repair! Cut the damaged area out, allow to dry, then apply caulk, smooth it, and the repair is done. 
  • Last Roofing: It has been said that a spray foam roofing is the last roof a commercial building owner will ever need to have installed. Maybe that is the most significant benefit of all! 

Is spray foam roofing good?

In addition to the seven benefits we listed, other features make spray foam roofing the right choice for commercial structures with flat or low sloped roofs—a common problem with a flat roof, the drainage. After a heavy rain or melting ice and snow, if the drains are maintained, the water has nowhere to go. Spray foam roofing is applied in layers of various thickness, which provides better drainage. 

The drainage issue goes hand-in-hand with condensation and ice damming, another issue with flat roofs that spray foam roofing helps. As the interior heat comes to the roof and melts the ice and snow, then the temperature drops and refreezes, this creates ice dams. That allows water to seep into ordinary roofing membranes. Because spray foam roofing is insulation, that heat from the interior of the building never makes it to the roof. Once the ice and snowmelt, it drains away.

What does a green roof do?

Updating Your Roof for the Better

Before we answer what does a green roof do, let’s take a look at what a green roof is! Nope, in this case, it is not the color of paint, shingles, or tile. As defined by Wikipedia, a green roof, also referred to as a living roof, is a roof with vegetation entirely or partially covering a flat rooftop. It is a growing medium that has been planted intentionally on a flat roof that has been prepared with a waterproofing membrane, a root barrier, a drainage system, and an irrigation system. 

What is a green roof made of?

The basic anatomy, listing in layers from the bottom up, are: 

  • Structural Roof Support
  • Vapor Control Layer
  • Thermal Insulation
  • Roofing Membrane Support for Planting
  • Waterproofing
  • Root Repellant
  • Drainage
  • Filter Membrane
  • Growing Medium
  • Vegetation

How is a green roof constructed?

The traditional soil that is in a typical yard garden or a house plant is dense, and after a rain or watering, it becomes tightly packed. This soil type has reduced aeration and water retention for the roots. The growing medium for a green roof is different.

 It is composed of mineral aggregates and a small amount of organic material. A green roof needs to have consistent drainage with aeration, and a structure that allows it to keep water contained. A green roof needs to resist compression and decomposition, remain lightweight, and be chemically and physically stable.

A green roof may be installed in one sizeable unified section and is a green roof without plastic separating the plants. A modular green roof will consist of small movable planting beds with metal or plastic trays housing the growing medium. The portable plant beds are then placed together, creating an extensive green roof. Because a modular green roof is planted in movable planting beds, it can be installed in increments that are removable for maintenance, allowing the root layers to be inspected easily from time-to-time. 

A modular sectioned green roof can be cultivated in a greenhouse and then planted on the green roof when the plants are established. There are fewer issues of any replacement plants that don’t take to root or struggle to thrive. A drawback to modular section green roof plants is the moisture can’t flow between the units, which increases the impacts of dry and wet spells for the plants.

Do green roofs need maintenance?

For a healthy and thriving green roof, like any other garden, routine and preventative maintenance is recommended. Having somebody in charge that has experience in gardening is always best. Because a green roof is typically on an elevated structure, safety training for anyone that will be tending to the green roof is recommended.

The primary tasks for ongoing green roof care and maintenance are based on the seasonal plant care, aka, the type of medium and vegetation planted, and the regional climate. Basic maintenance of a green roof is the same as a ground planted garden with watering, weeding, and basic plant care, such as pulling off dead leaves. The best measure for a healthy and thriving green roof is proactive maintenance.

What problems do green roofs solve?

Green roofs have been around forever, especially in Europe. They are gaining popularity in America as we have learned they aren’t just for looks, but the green roof benefits we receive may not seem like much, but they do a lot for our environment: 

  • A green roof absorbs heat and provides a natural layer of insulation, which reduces energy costs. A six-inch thick green garden can reduce energy usage by seventy-five percent because it takes less air conditioning to keep a building cool – a big plus for structures in the southern states.
  • A green roof reduces the Urban Heat Island Effect of absorbing and trapping heat. 
  • A green roof removes air particulates and produces oxygen, all while providing shade if there are trees planted in the garden. 
  • A green roof with trees not only provides shade for humans and the plants, but it minimizes the UV rays that shortens the lifespan of the roof.  
  • A green roof can minimize and slow stormwater runoff on to the hard surfaces of urban environments. Typical flooding and pollution because of nonporous surfaces are reduced with much of it absorbed by the green roof plants. 

How long do green roofs last?

A green roof and sustainability are a combination that this country has not taken full advantage of yet.  The estimated lifespan of a green roof is 40 years. That is 40 years of reduced energy needs, which reduces the greenhouse effects on the environment.  Considering the natural increased R-value, a green roof provides, naturally, not humanmade insulation. 

Last Words 

So, which do we get the most benefit when it comes to green roof vs cool roof? They are both beneficial in their way. A cool roof reflects the sunlight and heat, sending it back into the atmosphere. A green roof absorbs the sunlight and heat, keeping it from entering the structure and stabilizing the air to a near ambient temperature.

How Do You Fix Roof Flashing?

Do All Roofs Have Flashing?

Is roof flashing necessary? Hopefully, you don’t wait too long to find out. Flashing play a critical role in your roof system that keeps your property protected against rain, wind, small, animals, and several other potential dangers. When neglected, you expose your roof to leaks and it’s harder to control temperatures inside. Roof flashing and trim work together to keep your structure looking great and performing at a high level. Here we explore how roof flashing works and how repairs are handled in a way that extends the lifespan of your roof and helps to avoid larger repairs or emergencies.

To get the best results from your roof against the rain, flashing is a great idea. The majority of homes and businesses install and maintain flashing on their property to avoid water damage. Roof flashing is a thin, flat material that gives your roof’s edges a waterproof solution to keep water from getting underneath your shingles. Roof flashing is typically made from copper, stainless or galvanized steel, or aluminum.

Where Is Flashing on a Roof?

Your shingles funnel the water that hits your roof down along the sides of the roof where the flashing prevents it from seeping underneath the shingles and into your roof. If you walk outside and do a visual inspection of your home or commercial property, you should notice thin, the flat flashing around gutters, chimneys. roof flashing for vent pipe, and other areas. The main purpose of flashing is to provide a water-tight seal around areas susceptible to water leaks. That generally means around edges and corners.

Does Flashing Go Over or Under Shingles?

The answer to this question is that it depends on which shingles you’re talking about! Most flashing goes under some shingles and over others. For example, when you’re installing flashing where higher shingles meet a part of your roof that juts out, say a garage, then your flashing will be underneath the higher shingles and under the lower ones. The reason being that the flashing is meant to facilitate water movement. It prevents water from getting underneath the higher shingles while still allowing the shingles to feed water down to lower levels and eventually into the gutter system. By having the roof flashing on top of the lower shingles, it covers the cracks and seams between the two surfaces from water penetration. This and other roof flashing examples illustrate how critical it is to get placement and repairs done correctly.

Here are some more examples of places roof flashing goes:

  • Around Windows – Windows often have four seams that need to be treated with flashing. It’s important to stop the wind from entering and climate-controlled air from escaping. Flashing around the windows also stops rain from getting inside.
  • Chimneys – You don’t want water getting inside seams between your roof and your chimney. Flashing can do the trick as well as stop any small animals from getting inside.
  • Vents – Gable vents and other vents around your property will need flashing to seal around edges.
  • Eaves – Eaves need flashing to improve water flow and stop rainwater from getting under shingles and into your roof.
  • Where Two Edges Meet – Any place there two different angles or surfaces meet need edging.

Anything with exposed edges on your roof needs flashing for the best roofing system performance. Without proper flashing, you’re taking an unnecessary risk.

Do Roofers Replace Flashing?

Every good roofing company will have experience repairing, installing, and replacing flashing. Every homeowner or commercial property operator knows that everything on your roof has a limited lifespan. Keeping up a property takes constant upkeep. Eventually, though, you’re going to have to replace things, and flashing is no exception.

When you call for help with your flashing, it may be because you notice water spots on your roof or your gutter system isn’t working well. You may even see obvious signs of flashing decay where the flashing is separating from the structure and there are visible gaps between edges.

With the right roofing service, you’ll get fast help to get your flashing back in good condition. If repair is an option, the technicians can adjust your flashing back in place. However, if the flashing is too old or too damaged to work correctly, then replacing it is your best option.

Most skilled roofers will use a combination of flashing techniques to get your roof protected again. Here are some different types of flashing they’ll use:

  • Base Flashing – Base flashing refers to flashing that goes around the base of a vent, pipe, or chimney. It often requires multiple pieces of flashing that need to be molded to the structure’s size and shape.
  • Step Flashing – This refers to the flashing that’s installed between a roof and a wall. The piece of flashing is bent to match the angle of the two surfaces.
  • Continuous Flashing – This is often the most common type of flashing installed on properties because most edges are long, continuous lines that can use the same piece of flashing.
