Signs That the Sun is Damaging Your Roof and What to do About It
We know UV exposure can cause skin cancer in people, but few property owners realize how harmful UV radiation is for their roof. It may not be as serious as skin cancers in people, but being exposed to sunlight for hours upon hours day after day takes a real toll on roofing materials.

Roof Problems From Exposure to the Sun and UV Rays
Austin and the rest of Central Texas is known for its warm, sunny weather. Property owners have to choose their roofing material carefully in sunny locations if they want to get the longest lifespan out of their roof. Just as sun protection factor is a measure of how well sunscreen protects skin cells from UVB radiation, there are measurements for gauging how different materials are naturally protected against visible light as well as UV rays that can't be seen.
The big problem with the sun's rays is it can degrade the protective coating of a roof and cause premature aging of the materials, even changing their chemical makeup. When that happens UV light will do even more harm, eventually damaging the roofing materials to the point the underlayment is exposed.
Peeling
Peeling is another commonality between skin damage and roof damage that's caused by the sun. In the roofing world this happens when the clear protective coating is damaged and begins peeling off. This will cause noticeable discoloration as well.Blistering
Have you noticed the roof material bubbling up. This is what's known as roof blistering, and it isn't just bad for the appearance of your roof. Roof blisters can form for a variety of reasons, but sun exposure is often a contributing factor. Blisters form when moisture and/or air is trapped under the roofing material, heats up and then expands causing a raised bump.Leaks
All of the issues above can cause other bigger roofing problems like roof leaks. However, a leak usually takes time to form from sun damage and there will be other signs of damage before it gets to that point.

Correcting Roof Damage From Sun Exposure and Ultraviolet Radiation
Correcting damage from sun exposure is a must because if the problem continues the condition of the roof will only get worse, and it will continue every day once the sun comes up. What could have been a few minor repairs could turn into a complete roof replacement if sun exposure and UV radiation damage isn't fixed as soon as it's detected.
Getting a Roof Inspection is the First Step
Regular roof inspections are an effective way of catching UV damage early to minimize the problems and correct them. A professional roofer with experience will be able to spot the first signs of sun damage with a visual inspection. If the signs are there, the roofer can inspect further to see if the damage is more extensive.
Repairing, Re-coating or Replacing Damaged Shingles and Roofing Materials
The recommended solutions for correcting UV and sun damage all come down to how badly the roof has been affected and the type of roofing you have. In some cases, re-coating the roof is enough to restore it and prevent further issues. However, you may also need to repair or replace roofing that has cracked, broken or is damaged beyond repair. This could mean replacing a small portion or the entire roof.
If you do need to replace the roofing material, make sure the new roofing has a UV protective coating and/or reflective granules.
Keep Your Roof in Good Condition
Roof maintenance goes a long way toward preventing, detecting and correcting UV radiation damage. We always suggest that property owners get their roof inspected at least once a year to assess the condition, find damage that needs to be fixed and head off issues before they cause damage.
