Reasons Behind Roof Flashing Failure

If you’ve done a roof replacement project before, by now you should know that every part of the roof is important. Because each one supports the other. 

The shingles serve as a primary defense against brute impact of rainwater, snow, sunlight or hail. The underlayment keeps the roofing system safe from water damage. The gutter serves as the drainage system. The soffits and fascias protect the roof rafters. 

But then, there’s also the roof flashing. Many people don’t know about this particular part of the roof and why it is important. In this article, we are going to give roof flashing the recognition it deserves by answering why it’s so important in the roofing system. 

What Exactly Is Roof Flashing?

Have you noticed the metal sheet covering your roof edges? That’s what you call flashing. It protects vulnerable parts of the roof, where 90% of leaks happen when roof flashing fails to serve its purpose.

Lack of Information

A number of homeowners still don’t have any idea about their roofing system. So, when they call a contractor for a roof leak repair, they fail to point out the damaged or, at least, the affected parts and the materials needed to replace those parts, or provide a build plan from the previous project.

Wrinkled Flashing

When roofing materials are exposed to extreme temperatures, they tend to warp, expand or shrink, which causes pressure on other parts of the roof, such as the flashing, and causes wrinkles. With this constant warping, the flashing can get shorter or deformed, exposing the roofing system to water damages whenever a rain or storm comes. 

Poor Installation

The roof flashing can fail several months after the installation, not because of extreme weather conditions or temperature, but because of poor roofing service. Yes, the problem has begun long before it even begins to show. Poor installation could also be a result of foundation problems, such as tiny cracks and a leaning chimney.
