A wood-shake-look shingle built with rubber-polymer ClimateFlex® technology for improved hail resistance, granule retention, and cold-weather installation.

Landmark ClimateFlex combines a wood-shake aesthetic with a rubberized polymer formulation designed to flex rather than crack, improving impact resistance and making the shingle easier to install in cold weather. It's engineered for durability in regions that see frequent hail or severe temperature swings.
It's UL Class A fire rated and UL 2218 Class 4 impact resistant. Coverage includes a lifetime limited transferable warranty (50-year for other ownership), a 25-year algae-resistance warranty, 10-year SureStart™ protection, and a 15-year wind warranty upgradeable to 160 mph.
Passes the industry's two toughest wind tests: ASTM's 110 mph and 150 mph wind tests (under controlled laboratory conditions).
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 25 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 160 mph when installed with CertainTeed's specified starter strip and hip/ridge accessories.
When a full qualifying system is installed together — underlayment, water-resistant underlayment, starter strip, shingles, ventilation, and hip/ridge accessories — the roof qualifies for an unlimited wind-velocity warranty.
