The hottest days of summer can be hard on your roof. Your roof is exposed to intense heat for hours every day unless it's in shade. Summer also brings storms with strong winds, driving rain, and hail. Here's a look at how these summer dangers harm your roof and some ways a roofing contractor might be able to help.
How Summer Weather Can Hurt Your Roof
UV rays are damaging to asphalt shingles. That's why shingles are coated in granules. The granules create a barrier that shields the shingles and helps them have a longer life. However, it's common for your asphalt roof to lose granules over time. They get blown off by wind, scraped off by blowing tree branches, or get knocked off by squirrels scampering across the roof. When the granules wear away, your roof is more vulnerable to UV damage that can lead to curling or leaking.
The heat from the intense sun can also cause damage to asphalt shingles. This problem is made worse if your attic doesn't have a good ventilation system that keeps heat from building under the roof. Besides heat and UV rays, your roof may suffer from hail strikes that crack shingles and strong wind that blows shingles off the roof.
How A Roofing Contractor Can Help Your Roof
It's a good idea to check your roof for damage and age-related wear before summer begins to make sure your roof can stand up to another season of intense heat. It's also good to check your roof in the fall so a roofer can repair damage and get your roof ready for winter weather. Your roof might need repairs to shingles, or you may even need a roof replacement if your roof is old and unable to make it through another long, hot summer.
Mold, moss, and algae can sometimes be problems for asphalt shingle roofs. Humid summer weather can cause condensation to form and when moisture is on the roof for too long, mold can begin to grow. If the roof is in shade most of the time, algae can be a problem too. Algae leaves black stains that make your roof look worn out even if your roof is new.
A roofer can remove algae and add treatments to your roof to keep it from coming back. Moss is more serious than algae since moss destroys asphalt shingles by lifting the shingles with their roots. If you see moss growing on your roof, have it removed so it won't spread and do further damage.
When your asphalt shingles show signs of heat damage, the roofing contractor, like those at Pyramid Roofing Inc and other places, might want to inspect the ventilation system in your attic. If the system isn't adequate, the roofer can install additional vents or unblock vents so airflow is improved. Good ventilation protects your roof from heat buildup in the summer, and it protects against ice dams on the roof in the winter.
