How The Sun Affects Your Roofing

House roof

Providing your home with the best tools to combat the sun’s damaging effects is our number one priority at Horizon 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

If you live in dry, arid climates, prolonged exposure to the sun will likely cause your roofing materials to dry out, crack and break. 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 their damaging effects.

Thermal Shock

Your roofing materials will likely expand and contract due to extreme high and low temperatures, resulting in a phenomenon known as thermal shock. This can lead to the roof of your home becoming ineffective over time.

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


If you’ve noticed that your roofing materials are looking a little more dull than usual, the sun has likely bleached the color of your rooftop, leaving it looking dull and lifeless.

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 Sun’s UV rays coupled with the natural oxidization of materials may lead to your rooftop becoming brittle and eventually crumbling. The first signs of a crumbling roof are patches in your roofing as well as the discarded material in your gutters.

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.
