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.
