NorthGate ClimateFlex
An impact-resistant shingle purpose-built for severe-weather regions, combining a two-layer fiberglass core with algae-fighting technology.
Product Overview
NorthGate ClimateFlex is engineered for homeowners in hail- and wind-prone regions. Its two-layer fiberglass construction and rubberized polymer additive are designed to absorb impact rather than crack, while a 4-nail installation pattern and self-sealing bond help resist wind lift and water infiltration.
It's UL Class A fire rated and UL 2218 Class 4 impact resistant. Coverage includes a lifetime (residential) / 50-year (commercial) warranty, a 30-year algae-resistance warranty, 10-year initial coverage, and a 15-year wind warranty upgradeable to 160 mph.
Features & Benefits
Enhanced Impact Resistance
Proprietary SBS-modified asphalt formula for rubber-like flexibility and increased impact resistance.
Excellent Performance
Passes the industry's two toughest wind tests: ASTM's 110 mph and 150 mph wind tests (under controlled laboratory conditions).
Warranties & Protection
Lifetime Limited Warranty
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.
SureStart Protection (10-Year)
Full replacement cost coverage (materials and labor) for manufacturing defects during the first 10 years after installation, before any prorated reduction applies.
Limited Algae-Resistant Warranty (30-Year)
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.
Wind Warranty (Upgradeable to 160 mph)
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.
Integrity Roof System
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.
