June 15, 2023

Now that Summer is approaching, so are the sun's UV rays. While we all like to have some fun in the sun, your roof may not enjoy it. The sun's powerful UV rays could lead to expensive damage to your home's roof. Continue reading to learn more about the damage that UV rays can cause, how to prevent UV damage to your roof, and extend your roof's lifespan.

UV Ray Damage

Heat Breaks Down Roofing Materials

If you have dark color shingles and do not have any shade over your roof, your shingles will absorb heat radiated by the sun. This high temperature can then cause your shingles and other roofing materials to break down at an accelerated rate.

Fade Your Shingle's Color

Continued UV ray exposure can result in bleaching your shingles and fading the color on top of your roof. The darker your roof color, the more likely it is to experience bleaching. This is purely an aesthetic issue, but it can significantly impact the curb appeal of your home. Also, sun bleaching cannot be undone, making the only way to fix the sun-bleached shingles is by replacing them.

Dissolving The Coating

All shingles come with a coating on top to prevent weather-related damage. This protective coating can dry the coating out, allowing it to crack. These cracks can allow weather-related damage to take place, especially leaks. These leaks can then cause extensive water damage throughout your home.

Changes In Temperatures Causes Thermal Shock

During the summer, there is a significant difference in the temperature during the day versus the temperature at night. In the heat, your shingles will expand but in the cold, they contract. This continued expansion and contraction can cause your shingle to crack. Once these cracks exist, many different types of damage can occur, such as water damage and moss growth.

How To Protect Your Roof

Additional Coating

To prevent your shingle's coating from breaking down due to the UV rays, you can add an additional coating to make it more difficult to break down. This type of coating is typically made out of acrylic, urethane, or silicon with the goal of deflecting UV rays away from your roof and preventing heat absorption.

Light Shingle Colors

If you are planning on replacing your roof, you should consider changing to a lighter color shingle. Lighter colors do not absorb as much heat as dark-colored shingles due to the light colors being more reflective.

Improve Ventilation

One of the best ways to reduce the amount of heat that your roof absorbs is to install additional intake and exhaust vents to prevent heat from becoming trapped.
