Hail, high winds, and falling tree branches all pose potential roofing threats. However, some homeowners are unaware that sunlight can play a role in damaging the roof, too. While there are many reasons to look forward to spring—and the warmer days and sunnier skies that come with it—here are some potential problems it can cause.

4 Ways UV Rays Can Harm Your Roof

1. Expansion & Contraction

During the warm months, asphalt shingles can get extremely hot. As the thermometer rises, they expand, potentially expelling protective granules as the adhesive warms up and melts. These tiny pebbles can clog the gutters, and their presence indicates the need for shingle replacement.

2. Evaporating Oils 

As sunlight radiates onto roofing, the oils in the shingles will evaporate. This can turn shingles that were once flexible into brittle, rigid pieces, leaving them at greater risk of damage over time. If you’re concerned about this issue, talk to a roofing contractor about applying a UV-resistant coating to the roof or installing metal roofing to mitigate the effects of sunlight.

3. Fading

When first installed, most shingles are strong in color. However, over time, shingles are likely to fade due to sun exposure, which can affect the curb appeal of your house and also decrease the overall life span of the roofing material. Additionally, this bleaching can reduce the amount of heat your home absorbs, making it less energy efficient in the winter.

4. Curling

As the shingles experience sudden temperature changes—for example, as the day goes into night—they may undergo thermal shock. This abrupt adjustment can make shingles curl, creating vulnerable spots.
