Owens Corning Duration Onyx Black shingles deliver 130 mph wind warranty protection through patented SureNail® Technology — a tough, woven-fabric reinforcing strip in the nailing zone. Each square covers approximately 100 sq. ft. with Class 3 Impact Resistance that matters for Montana’s hail-prone regions. 90% of contractors favor the Duration series, and the numbers explain why.
Wind Performance and Installation Technology
The 130 mph wind warranty comes from SureNail® Technology — a woven-fabric reinforcing strip built into the nailing zone. The No-Guess Nailing Zone provides a wide area for consistent and accurate fastener placement. No more guessing where to drive nails on a freezing morning when fingers are numb.
Triple-Layer Protection® adds extra strength at the shingle overlap — the spot where most shingles fail first. SureNail technology provides a clearly defined ‘no-guess’ zone for fasteners. The reinforced nailing zone delivers superior nail pull-through resistance and wind uplift protection.

Coverage Specifications and Professional Features
Coverage runs 98.4 sq. ft. per square (approx. 100 sq. ft.), with 3 bundles covering the square at 32.8 sq. ft. per bundle. 64 shingles per square works out to approximately 21-22 per bundle.
StreakGuard Algae-Resistant Coating keeps black shingles looking black, not streaked with algae. The algae resistance warranty runs 25 years. UL 2218 Class 3 Impact Rating means these shingles can take a beating from hail. That Class 3 rating potentially qualifies homeowners for insurance discounts.
The shingles work with standard plywood or OSB roof decks and integrate into the Owens Corning Total Protection Roofing System — designed to work with OC starter shingles, hip & ridge shingles, and underlayment.

The 130 mph wind warranty handles Montana’s chinook winds and mountain gusts. Class 3 impact rating survives the hail storms that roll through every summer. No-Guess Nailing Zone speeds installation when daylight’s burning.
