Flashing is one of the most important components of your roofing system. It is responsible for creating a barrier that prevents water from leaking through the roof. Unfortunately, mistakes made during the installation and upkeep of the roof can cause the flashing to be less than effective. Here are some of the most common mistakes that can occur with your roof’s flashing.
Improperly Securing the Flashing
One of the most vulnerable spots on your roof is the point at which the flashing ends. If the flashing is not properly secured, it can start to rise and allow in water. If you live in a rainy area, this could prove to be especially problematic.
Before securing the flashing, you have to ensure that the seams are properly aligned. The single-ply flashing can then be securely welded to the surface or glued. If not, the flashing could lead to blow-offs. You could even face municipal fines because there are building codes that dictate how well the flashing has to be secured.
In an effort to save money, some homeowners attempt to reuse some parts of the roofing system. Although there are some parts that you might be able to reuse, the flashing should not be.
During the removal of other parts of the roofing, the flashing is typically rolled down to remove it. When the flashing is rolled down, it often becomes misshapen. As a result, if you reuse it, you will have trouble with attempting to secure it. The problem could even make it difficult to place the shingles in place.
The misshapen flashing is also more likely to blow off, which could mean water flooding into your home during a storm. Always replace the flashing to avoid this issue.
Using Single-Piece Flashing in the Wrong Places
Single-piece flashing seems like an easier method of covering areas of your roof, but it can sometimes create bigger problems. For instance, whenever one part of the flashing raises due to high winds, the whole piece is left vulnerable. Instead of replacing or repairing a small panel of flashing, you have to take care of the entire single-piece.
Single-piece flashing also does not allow for water to drain from the roof the same way as other flashing methods, such as step flashing. When water accumulates on a single-piece flashing roof, the water tends to pool up near the point where the roof meets the wall, which pushes water into your home.
