CertainTeed’s Grand Manor® UL 2218 Class 4 impact-resistant and algae-resistant shingles are a premium roofing solution crafted to closely emulate the refined appearance of natural slate. Their substantial weight combined with a broad, irregular tab pattern creates a dimensional, high-end look while still delivering the practical benefits of an asphalt roofing system.

These shingles carry a Class A fire resistance rating from Underwriters Laboratories, the highest level of fire protection available for residential roofing products. They are also engineered for strong wind performance, with the ability to withstand gusts up to 110 mph, helping maintain roof stability during severe weather conditions.

Grand Manor shingles are offered in nine distinctive color blends, each designed to enhance architectural character and provide a sophisticated, upscale finish. To help maintain long-term visual appeal, StreakFighter® technology is integrated to reduce algae growth and limit the appearance of dark streaking over time.

Built on a durable fiberglass mat foundation, the shingles are coated with asphalt and reinforced with ceramic-coated mineral granules to improve resistance against harsh environmental exposure. Their multi-layer construction and heavier profile contribute to increased durability against impacts from hail, heavy snow, and high winds.

For installers, Grand Manor shingles include self-sealing adhesive strips and a randomized tab layout that supports a more natural slate-like installation pattern while still allowing for a clean, professional finish. This combination helps improve installation consistency and final roof appearance.

Backed by a limited lifetime warranty, these shingles are designed to provide long-term confidence and protection. Overall, Grand Manor delivers a strong blend of architectural elegance, advanced durability, and reliable weather resistance, making it a premium choice for homeowners seeking a high-end roofing aesthetic with long-lasting performance.
