Granule Loss and Shingle Oxidation from Summer Heat
Sacramento Valley summers push temperatures past 95°F for weeks at a stretch, stripping granules from composition shingles and oxidizing the asphalt mat beneath. Once granule loss exposes the mat, water-shedding capacity drops sharply and a rated 25-to-30-year lifespan shrinks considerably. California Title 24 cool-roof requirements specify a minimum aged solar-reflectance rating for steep-slope replacement materials, which reflects more of the sun's heat away from the deck and can measurably lower attic temperatures and summer cooling bills. Our installers select manufacturer-specified products that meet those standards to restore performance and slow future degradation.
