Inclement weather is a common cause of roof damage, but sunlight can be equally problematic. Many homeowners don’t realize that UV rays can penetrate shingles, leaving them vulnerable to warping and cracking. If you want to learn more about how this happens, here’s a guide to how the sun affects residential roofing and what to do about it.

How Does the Sun Affect Your Roof?

UV rays can penetrate nearly anything, and as they pass through a roof, they cause damage to the structure of the shingles. Over time, this weakens the material and increases the risk of cracks, displacement, and curling, which leads to leaks and water damage to the attic and siding. It also wears down waterproof coatings and seals over time, further increasing the risks.

Sunlight also impacts a roof's visual appeal. Since the surface materials break down, the color can fade or become patchy. This is especially noticeable in residential roofing that is visible from the ground. 

How to Combat Roofing Sun Damage

The key to protecting your roof is maintaining it. Look for signs of damage, like cracked, curling, or discolored shingles. When such issues are present, consider replacing the problematic pieces with new shingles that are designed to combat UV rays. For instance, GAF's TimberlineⓇ Cool SeriesⓇ is coated with a sealant that reflects rather than absorbing sunlight.

If there's extensive sun damage, a roof replacement is an cost-effective option to prevent leaks that could cause costly insulation and attic damage.
