How Heat Affects Your Home’s Roofing System

by | Jul 21, 2021 | Blog, Roofing | 0 comments

The summer is a time of year that almost everyone looks forward to. The sun makes it easier for you and your friends to spend the day outside, go on vacation if desired, or soak up those happy vibes from doing anything at all in the warm weather.

As fun as the summer is, the sun can take quite a toll on houses and roofing systems. Overexposure to extreme temperatures and UV rays can be detrimental to your home’s roof; it can deteriorate your roofing materials and drastically reduce the lifespan of your roofing system.

If you think that your roof may be suffering due to the extreme heat, carry on reading as we detail the way heat impacts your roofing system.


Thermal Shock

Thermal shock occurs when your roofing system is exposed to a continuous cycle of expansion and contraction due to day and night temperatures. This continuous expansion and contraction lead to roofing materials weakening over time, leading to their eventual degradation.



Dark roofing materials are known to absorb quite a bit of heat. Being exposed to high temperatures over a long period speeds up the chemical processes occurring within the materials. This acceleration leads to the breakdown of your house’s roofing materials. Overexposure to heat will cause asphalt shingles to crumble and curl, metal sheets to warp, and clay tiles to crack.



Hot, humid air is actually a menace to your roof. It combines the destructive elements of both heat and moisture, leading to the rapid deterioration of your roofing system. Humidity may lead to condensation on rooftops that can cause mold and mildew growth as well as weakening structural materials like shingles or tiles.


Fire Hazard

It’s always important to clear your roofing system of any dirt and debris. Things like dried leaves, twigs, and pine needles can become a fire hazard on your roof. If a fire breaks out on your roofing system, you risk destroying your roof and home in the process.
