When it comes to your residential roofing system, the failure of one component can affect the performance of the entire roof. In this article, Residential Concerns discusses common reasons behind roof flashing failure and what you can do about this problem.
Roof Flashing Basics
The flashing is a material installed where two parts of the roof meet, such as the valleys, slopes and vents. Flashing is also installed around chimneys, skylights and other protrusions in the roof. These intersecting parts are more prone to leaks than anywhere else on the surface of the roof, so the flashing is there for extra protection. Roof flashing is usually made of galvanized steel, but aluminum, copper and plastic variants are also available.
What Causes Roof Flashing Failure?
One of the leading culprits when it comes to flashing failure is shoddy workmanship from the roofer. Improper or haphazard installation can render the flashing material inefficient against leaks and other types of water damage. The second most common cause of roof flashing failure is using the wrong material. Different or incompatible materials can result in galvanic corrosion, which occurs when dissimilar metals come into contact with one another. Aluminum and copper should not be used together, while bronze and copper can safely be utilized in the same roofing system.
It goes without saying that knowledge and experience are paramount when it comes to preventing flashing failure. This is why you should only work with a reliable roofer.
