From extreme heat to UV exposure, summer weather conditions can cause serious harm to your roofing materials. A roof coating creates a resilient barrier to prevent damage and increase longevity. Learn more about the effects of the sun on your roof and how a coating will protect it in the guide below.

How Summer Heat Affects Your Roof

UV rays from the sun can damage your roof, causing premature aging and decay. While most harmful during the heat of summer, ultraviolet rays can even cause harm on cloudy days. An unprotected roof can reach temperatures as high as 150 degrees on a hot day, accelerating chemical processes that cause asphalt shingles to buckle and split. It can also cause wood fascia boards to bleach, weaken, and crack, resulting in leaks.

An unprotected roof will transfer heat to your attic, causing it to overheat and create moist air that then condenses, leading to wood rot.

Additionally, thermal shock, which occurs when high daytime temperatures rapidly cool as the sun sets, can cause your roofing materials to expand and contract, weakening its structural integrity over time. 

Benefits of Roof Coating

A roof coating acts as a barrier between your roof and the elements, lowering its surface temperature and decreasing your home's interior temperatures. This, in turn, can reduce your energy use on hot days. It also helps reflect UV and infrared light, diminishing the sun's damaging effects.

Some coating materials can improve your roof's waterproofing, helping prevent leaks, rot, and mold growth. Reflective coating can help your roof maintain its color, improving the overall appearance of your home as it ages.

Coatings are formulated to adhere to a wide range of roofing surfaces, including metal, asphalt, composite, galvanized metal, and wood.
