How UV Radiation Can Harm Your Roofing in Fairfax

Fairfax Roofing Expert

This scorching heat of summer can be hard on your roof. If you cannot remember the last time you had a reliable roofer in Fairfax examine your roof, now is the time to do it. You would be surprised how many homeowners forget about their roof until they need a new one. However, you will get more life out of your roof with routine inspections and maintenance.

In today’s blog, we are going to discuss how heat can take its toll on your roof.

UV Deterioration

Four our of five homes have an asphalt shingle roof. Ultraviolet radiation can decrease the life of your asphalt shingles by penetrating down to the chemical compounds and deteriorating them. As these compounds fail, the oily substance that covers the shingle dissolves. This leaves them unprotected, dry, and prone to crack.

Thermal Trauma

Simply put, this is expanding and contracting of the roofing materials. It happens when high temperatures and continuous sunlight are followed by a rapid cooling process such as an afternoon thunderstorm, or even something as simple as the sun setting on a blazing hot day. As this expansion and contraction process repeats itself it puts considerable strain on your roof. Older materials can crack, blister, or buckle during this process, making all the more reason to call an expert for roof repair in Fairfax.

What Can You Do to Prevent Damage From The Summer Heat on Your Roof?

If you want to protect your roof from heat damage the most effective way is to start with high-quality roofing materials with exceptional durability. Low-slope roofing can be coated with specific water-proofers that are also designed to reflect the UV rays from the roof thus keeping the structure cooler and in return more energy efficient. Steep slope roofing systems can get shingles with cool roofing technology such as the GAF Timberline Cool Series, or a metal roof with UV reflective coatings. There are so many possibilities that we will discuss in another blog.
