From the maker · Owens Corning’s description
Owens Corning TruDefinition Duration COOL shingles use solar-reflecting granules to help reduce heat transfer into your home while delivering rich, vibrant color. Built with patented SureNail Technology, these laminated asphalt shingles offer durable performance with 130‑MPH wind resistance and a limited lifetime warranty.
Cool, Sophisticated Curb Appeal
Mountainside brings a nuanced gray palette that drapes the roofline in a refined, shadowed texture—elevating everything from brick to board-and-batten facades. The TruDefinition color platform creates dimensional depth, while the COOL granules quietly work to temper the sun. Pair with matte black gutters and warm wood doors for a tailored, modern exterior. It’s a smart, stylish essential for luxurious, performance-forward homes.
Choose Duration COOL Mountainside to upgrade your roof with striking color, cooler performance, and proven durability—order your bundles today.
