How the Summer Heat Can Affect Your Residential Roof

​With the summer months approaching, you may not be thinking too much about roof maintenance. After all, no leaves are falling or cold weather to cause potential problems. While this is true, your roof still requires upkeep during the summer months.

Hot weather brings in a few unforeseen issues. Get to know how hot weather can damage your residential roof so you can take steps to prevent problems.

UV LightUV or ultraviolet light can cause roof damage, especially in the summer when light hits surfaces at “full strength.” It may even penetrate on overcast days. This means that no roof is safe from exposure to UV light during the summer.

Over time, UV light exposure can impact roof quality. It can cause the materials to decay faster, and eventually, the shingles may buckle, split, and peel while wood cracks and appears bleached. The protective oils in your roof may start to dry out, too, making it brittle, dry, and more susceptible to damage.

High TemperaturesIf your roof is exposed to the sun, it is extremely vulnerable to extensive heat damage with no shade. For example, on a hot, 90-degree day, the temperature that your roof reaches can exceed 150 degrees. This is especially true if your roof is made from darker materials that absorb the heat. The higher temperatures will also cause the materials used for your roof to break down faster.

High HumidityTemperature increases can also cause sticky, humid weather. When air is humid, condensation may accumulate under your shingles. The collection of water can result in serious damage and eventually leaks. Also, as moisture stays “stuck” in one place, mold may begin to develop. Not only does this cause further roof damage, but it is also a health hazard.

Thermal ShockDuring the summer, the temperatures on your roof can go extremely high during the day and then cool down quickly when the sun goes down. This sudden and rapid change in temperature can result in the contraction and expansion of your roof. This will result in the tension of the roof materials and a shorter lifespan. Also, sudden changes in temperature like this will weaken the integrity of your home’s roof structure as time passes and may cause a split or warped roof.

Tips for Preventing Damage to Your Residential RoofWhile all the factors above can result in serious damage to your roof during the summer months, there are a few ways that you can protect your roof, too.
