Prepare Your Roof for Summer Heat

You might be ready for the return of summer, but is your roof? Before you break out the bug spray and sunscreen for yourself, take some time to consider what effects summer can have on your roof and how you can make sure your roof is ready to keep you and your home protected.

Heat and UV Light

In the summer, your roof absorbs a lot of heat and UV rays from the sun. This ultra-violet light—even on cloudy or overcast days—can dry out roofing materials and cause them to become dry and brittle and eventually crack, which can cause leaks.


If your attic isn’t properly ventilated, moisture and humidity can get trapped in your attic and weaken your roof from the inside. Cooler air from your air conditioner inside your home can also cause condensation to build up on your roof and lead to moisture problems.

Moss and Algae

You’ll want to keep an eye out for moss and algae growth on your roof, as summer’s heat and humidity can encourage it to grow quickly. Moss and algae growth can trap moisture on your roof, which can weaken your shingles.

What can you do to prepare your roof for summer heat?

Ultimately, there isn’t a lot you can do to prevent summer heat and sun from wearing on your roof, but keeping your roof regularly maintained puts it in a better spot to weather summer, or any season, for that matter.

Regular roof maintenance in the summer is a lot like regular roof maintenance the rest of the year: keeping gutters clean, having any debris removed from your roof and having shingles or flashing that may have been damaged by the previous season inspected and replaced if necessary. If you dread having to clean out your gutters (or hiring someone to do it for you), the summer is a great time to consider having leaf guards installed before the fall foliage starts to drop.

It’s recommended that you have your roof inspected at least once every year or two to keep it in the best shape regardless of the season. Again, as with roof maintenance during any other time of the year, you’ll want to take particular care and pay extra attention to your roof if it’s older and possibly have it inspected more than once a year.

Because excess heat and humidity trapped in your attic can cause issues with your roof and roof decking, you should make sure your attic is properly ventilated. A roofing contractor can check your roof’s exhaust and intake vents and make sure your roof’s ventilation system is performing properly. A good roof ventilation system doesn’t just help your roof in the extreme heat of summer, it can also help prevent ice buildup and damming in the winter and make your home more energy efficient year-round.
