How Can the Sun Damage Your Roof?

June 4, 2020 11:02 pm Published by Leave your thoughts

It probably comes as no surprise that your roof is under constant assault. The wind pulls at your shingles. The rain threatens to force water into your home. The snow freezes and degrades your roof. There’s so much out there that Mother Nature throws at the first line of defense your home has against the elements. However, the most common threat to your roof isn’t the wind, rain or snow.

In fact, the most common reason for needing roof repair in New Bern, NC is the sun beating down on your roof day after day. What happens when your roof is over-exposed to the sun? Read on to find out.

Cracks and splits

Every day, the sun is attacking your roof with harsh UV rays. Ultraviolet rays slowly leech your roof’s materials of their inherent moisture. When they dry out, wood roofs can bleach and crack. Asphalt shingles, meanwhile, curl under the pressure of constant UV exposure and split.


You may not give it much thought, but the sunlight hitting your roof on a hot summer day can have a drastic impact on your home. Consider this: when it’s just 90 degrees during the day, the temperature of an asphalt roof can get as high as 150 degrees. If your attic space isn’t adequately insulated, condensation could form that undermines the structural integrity of your entire roof.


For those homeowners with an asphalt shingle roof, the sun’s rays can eventually cause the shingles to warp. This compromises their ability to protect your roof from the elements. If you’re noticing warping on your shingles, it’s essential to get a pro to look at your roof as soon as you’re able.

Growing and shrinking

Prolonged exposure to UV rays combined with temperatures that rise and fall sharply can be horrendous for your roof. The condition is known as thermal shock. As temperatures rise, it causes your roofing materials to expand slightly. When they fall again, your roofing materials will shrink slightly. As you can imagine, when your roofing materials are constantly expanding or contracting, they’ll eventually break down.

Older roofs need more attention

Newly-installed shingles tend to hold out better against sun damage, naturally, but the longer they are exposed to sunlight, the weaker they become. One or two broken or degraded shingles on your roof can pose a potential threat to your roof’s entire structure.
