How Does Hot Weather Affect Your Flat Roof?

By Stacy Mellete

It’s already summertime and if you have a flat roof, we recommend having it inspected by a professional roofing contractor to check its condition, as well as to determine whether or not it needs residential roof repairs. The hot weather can be quite damaging, after all. 

Here’s how:



Heat Can Damage Flashing

Flashing damage is usually caused by mold and fungal growth from moisture build-up. The growth can actually increase when there’s plenty of sunlight and heat, which can deteriorate your flashing. If it gets damaged, then your flat roof will begin to fail and water will leak in, which can further damage its interior structure.

Heat Also Causes Thermal Expansion 

Flat roofs tend to expand and contract during the summer and winter months, which allows water to penetrate into the roof. As reputable residential roof installation roofer Tampa, we recommend using modern materials such as single-ply PVC membrane, which are engineered to form a 100% watertight covering that withstands most weather elements.

With breathable single-ply PVC, your flat roof won’t be affected as much by condensation.

Blistering Can Also Happen to Your Flat Roof    

When water penetrates felt underlayment through a crack or hole and is exposed by the sun’s heat throughout the day, it expands the material and results in blisters or bubbles. Luckily, you can have the affected areas replaced if found early on. However, we recommend having a full replacement instead, especially if blistering becomes a recurring problem on your flat roof.
