Thermal Cycling: How Temperature Swings Shorten Roof Life
Thermal cycling happens to every asphalt roof in the United States every single day as temperatures rise and fall. You can’t stop it, and depending on where you live, the local climate may even make it worse. The good news is that roof restoration, shingle rejuvenation, and attic ventilation improvements can help you fight back and slow it down before it can severely damage your shingles.
How UV Radiation Breaks Down Asphalt Shingles Over Time
High temperatures can wreak havoc on an asphalt shingle roof, but it’s actually the UV rays in sunlight that cause the most damage. These shorter-wavelength forms of light transfer much more energy into your shingles, which can cause the petrochemical oils inside the core to evaporate or harden. Shingle rejuvenators like Roof Maxx treat this problem at the root by replenishing these lost oils so the shingle feels soft and flexible again.
