A premium slate-look shingle with Class 4 impact resistance and algae protection, engineered for high-wind regions with nine distinct color blends.
Grand Manor is one of CertainTeed's top-tier designer shingles, built to replicate the deep texture and shadow lines of natural slate. It's rated for 110 mph winds and constructed for long-term durability on higher-end residential roofs.
It's UL Class A fire rated and UL 2218 Class 4 impact resistant. It carries a lifetime (residential) / 50-year (commercial) warranty, a 30-year StreakFighter® algae warranty, 10-year SureStart™ protection, and a 15-year 110 mph wind warranty.
Bold shadow lines and tapered cut-outs create the appearance of depth and dimension.
Covers manufacturing defects for as long as the original owner-occupant owns and resides at the property. Other ownership types (commercial, rental, HOA, and similar) are covered for 40 or 50 years depending on the product line. Transferable once to a subsequent owner.
Full replacement cost coverage (materials and labor) for manufacturing defects during the first 10 years after installation, before any prorated reduction applies.
Covers cleaning or replacement if algae-resistant (AR) shingles develop blue-green algae staining, for up to 30 years when CertainTeed AR-designated hip and ridge accessories are installed. Coverage is limited to 10 years if those accessories aren't used.
Shingles are warranted against wind blow-off, including gusts, up to 110 mph for the first 15 years, upgradeable to 130 mph when installed with CertainTeed's specified starter strip and hip/ridge accessories.
