What Causes Roof Flashing Failure?

Flashing is metal sheeting that protects your roof from leaks. It provides an extra layer of material to redirect water to the ground. Typically, roofers install flashing on the vulnerable areas of your roof. One of the reasons for house leaks is flashing failure. Look at some causes of roof flashing failure.

1. Incorrect Installation

You can save money by installing roof flashing on your own. However, incorrect installation is one of the main causes of roof flashing failure. For best results, leave the flashing installation to the professionals.

When you do not fasten the flashing properly, it can pull away from the roof. Another sign of improper installation is when the nails start popping out of the roof decking. This is because you drove the nails crookedly or used the wrong types of nails. Eventually, this will cause the flashing to pull away.

2. Membrane Shrinkage

When the dimensions of the roof membrane shorten, this leads to shrinkage. The shrinkage exerts pressure on the flashing and roof seams. Over time, the flashing and seams will burst. Consequently, water can seep into your home and cause structural and property damage.

3. Inclement Weather

Bad weather can take its toll on your roof’s flashing. For example, rain, hail, and high winds can damage the soft metal of the flashing. Additionally, if a storm breaks a tree limb that falls on your roof, the most vulnerable part is the roof flashing.

Also, during winter, flashing tends to warp because of repeated contraction and expansion of the roofing materials. As a result, the metal starts to wrinkle and shrink in length. This creates gaps on your roof, leaving the roofing system susceptible to leaks, debris, and air infiltration.

4. Settling Foundation

Your home will often sink into the ground. The risk arises if substantial settlement happens due to extreme weather conditions and improper soil preparation.

When the foundation of your home settles, it may loosen the flashing. The main areas a settling foundation affects are the flashing around the chimney or fireplace. The first obvious sign is flashing pulling away from the chimney.

5. Old Age

Like any other roofing component, flashing wears out with age. So, when should you install new flashing? This depends on the building plans and roofing warranties.

Replacing your flashing goes hand in hand with a roof replacement. For instance, an asphalt roof lasts up to 30 years, while a metal roof can go for up to 70 years. Therefore, flashing starts to rust and fail around this time. If you are still in doubt, invite a roofer to inspect your roof’s flashing and determine whether you need to replace it.

Flashing is an essential part of your roof’s structural integrity. If leaks happen in your flashing, the water will often seep through the ceiling. This will affect the drywall because it becomes saturated and finally collapses, leaving a hole in your ceiling. Instead, hire a professional roofer to replace your flashing before it leads to costly home repairs.
