Summer sunshine is beautiful, but intense UV exposure can shorten roof lifespan by degrading shingles, fading colors, weakening adhesives, and accelerating wear. Here’s what to watch out for:
- Granule Loss & Asphalt Breakdown: UV rays degrade the protective granules embedded in shingles, exposing asphalt to brittleness and cracking over time. A tell-tale sign: granule accumulation in gutters.
- Micro-fractures and Cracks: In impact-damaged areas, UV exposure deepens weakened spots, making shingles brittle and prone to leaks. Usually noticeable near the edges or in hail-damaged areas.
- Accelerated Aging: High heat and UV combine to speed up weathering, causing shingles to curl, warp, and lose performance prematurely. Faded or discolored shingles are a warning sign.
The Right Products Resist UV Degradation
Engineered for long‑term durability, CertainTeed roofing systems employ advanced materials for proven protection against heat, impact, and UV exposure. ClimateFlex® polymer‑modified asphalt locks granules in place for stronger adhesion and improved flexibility in hot conditions. Class 4 impact‑resistant shingles help maintain granule coverage after hail impacts, preserving critical UV protection. And Cool Roof technology reflects up to 27–40 percent of solar heat and UV rays, helping to lower surface temperatures, reduce thermal stress, and slow the aging effects of the sun.
Landmark® PRO
- Premium, multi-layered laminate shingle with QuadraBond® reinforcement and CertaSeal® wind-sealing adhesives.
- UL Class 3 impact resistance, algae resistance, and robust shingle adhesion help combat granule loss and UV wear.
Landmark® Solaris® Cool Roof
- Dual-layered, solar-reflective shingles that reflect up to 40 percent of UV and heat.
- Meets multiple cool-roof standards (CRRC, California Title 24), with UL Class 3 impact resistance and algae protection.
Cover Up!
Prolonged summer sun accelerates shingle aging through UV degradation and thermal stress. CertainTeed tackles this with smart material innovations:
- ClimateFlex® and Impact-Resistant designs that preserve granule layers and structural integrity.
- Solaris® Cool Roof solutions that reflect UV and heat, reducing roof stress and energy costs.
For homeowners seeking long-lasting, UV-resistant roofing, choosing Landmark® PRO or Solaris® Cool Roof ensures strong protection—keeping roofs durable, beautiful, and shielded from the sun.
