Hot weather can be harmful to flat roofing materials such as felt and bitumen. The sun damage your flat roof sustains can weaken the system enough to cause leaks and other issues. Gulf Coast Roofing, a trusted shingle roof installer in the area, discusses the type of damage roofs can sustain due to constant exposure to heat from the sun.

1. Blisters. These refer to the bubble-like protrusions on the surface of a flat roof. Blisters generally occur when water seeps into a crack in the roof membrane and then expands when heated by the sun for an extended period. If you catch them early, it might be possible to just have the blistered section replaced. If not, complete roof replacement may be required. You should make sure to address blisters on your roof promptly because they will only worsen with time and cause bigger, costlier problems down the road.
2. Thermal Movement. Your flat roof may expand and contract because of the continuous cycle of heating and cooling it’s exposed to as the weather changes. This much thermal movement makes the roof susceptible to water intrusion, allowing for leaks. To prevent this issue, you should consider choosing a high-quality, water-tight material for your flat roof.
3. Poor Roofing Installation. If your flat roof was incorrectly installed, heat-related damage will be accelerated. Does your flat roof sag in the middle and allow rainwater to gather? When that pooling water is exposed to the sun, it serves as a sort of magnifying glass that accelerates damage to the material below, which in turn, results in leaks.
