How The Summer Heat Can Affect Your Roof

How Summer Heat Can Affect Your Roof

Most homeowners know that the winter season usually causes the most damage to the roof. However, the summer heat brings with it its own threats that can cause serious problems. From summer storms and wind damage to heat degrading the materials, there are a plethora of issues that can cause harm to the roof. So, let’s take a deeper look into how the summer heat can affect your roof. 


UV Exposure

The UV rays from the sun are constantly beaming down on your roof which can cause it to age and decay. And while this is also on cloudy days, it becomes especially harmful during long and sunny summer days. The energy at this wavelength, while not visible to the naked eye, can cause wood to bleach, weaken, and even crack. It can also cause the oils in your roofing material to dissipate and force asphalt shingles to buckle and split.



If your roof is not shaded, the dark colors will absorb heat and on a 90 degree Fahrenheit day, it can reach temperatures as high as 160 degrees Fahrenheit. At such high temperatures, it can accelerate the chemical processes and cause your roof to break down faster. Be sure to have proper attic ventilation as it can prevent heat buildup from hearing your home’s interior and also cause issues with condensation.


Summer Storms

Wind and hail can cause serious damage to your roof’s integrity. This is why it’s important to do your due diligence in dealing with these issues in the spring by checking for damage to the structure from the attic, checking for damp patches under the eaves, checking for gutter blockage, and also damaged shingles and roofing materials. Taking care of these should keep you in good shape for the summer. 


Thermal Shock

During the day, the roof on your home will reach very high temperatures and then quickly cool off when the sun sets. This can cause the roofing and construction materials to expand and contract, weakening your roof’s structural integrity over time. This can be especially problematic for metal as it is able to warp out of shape and create gaps. 


Most of the damage that can be caused to your roof during the summer is cumulative so it will take time. Catching problems early and taking care of the repairs as soon as possible will always be the best option and less expensive than replacing your roof.
