How The Sun Affects Your Roofing

Jul 12, 2021Blog, Roofing

The Sun is the source of life for all things on Earth. It helps the plants and trees grow, provides us with vitamins and minerals, and allows us to generate and store solar energy. As awe-inspiring as the sun can be, it can also have a destructive side to it. The sun’s UV rays can cause substantial damage to our skin, and with prolonged exposure, it is capable of scorching your home’s roofing system.

Providing your home with the best tools to combat the sun’s damaging effects is our number one priority at River Run Roofing. We believe in equipping your home with heat-resistant roofing materials so that your home has adequate protection for decades to come.


These are some of the ways in which the sun can damage your home’s roofing system:


Cracking and Breaking

The sun is a beautiful thing, but prolonged exposure can turn your roof into an eyesore. For those homeowners in dry, hot climates, it’s important to keep up on repairs before you’re left with nothing more than harsh sunlight shining through our attic and ceilings.

Some roofing materials are better than others at resisting the sun’s harmful UV rays. Roofing materials like metal are excellent at reflecting these UV rays, thus reducing its damaging effects.


Thermal Shock

The significant changes in temperature from day to night can cause your roofing materials to undergo thermal shock. Thermal shock takes place when daytime heat causes your roofing materials to expand rapidly, and then when nighttime comes around, its frigid temperatures lead to your materials drastically contracting.

This continuous expansion and contraction process may lead to the degradation of your roofing materials and their eventual breakdown.



Your once beautifully colored roofing system may be looking a little dull due to the bleaching effects of the sun’s rays.

A bleached roof will likely make your home look old and aged and thus ruin your home’s curb appeal. Luckily your roof can easily be repainted or recoated and returned to its former glory.



The sound of your roofing materials crumbling to the ground is something that you don’t want. Sadly, it can happen over time due to a combination of prolonged UV exposure and oxidization.

If you’ve noticed any sun damage occurring on your roof, it’s vital to schedule an inspection with your local roofing company. Getting an idea of how bad the damage is essential to your roof’s lifeline. You’ll be able to decide whether or not your roofing systems require some repairs or an entire roof replacement.
