Owens Corning Duration in Tulsa's Wind Environment
Owens Corning Duration shingles combine premium aesthetics with industry-leading wind resistance — making them the ideal choice for Tulsa homeowners in Oklahoma's 115-mph basic wind speed zone. As an Owens Corning Preferred Contractor, Proof Construction has installed thousands of Duration systems with zero wind-related failures.
Wind Resistance Specifications
- SureNail Technology: Engineered nailing zone with reinforced fabric for improved nail-holding power. Reduces nail pull-through by 35% compared to standard shingles.
- WeatherLock Self-Seal Adhesive: Advanced sealant strip that activates at lower temperatures (40°F+) — critical for Tulsa's fall and spring roofing season when temperatures fluctuate.
- Class 4 Impact Rating: Duration shingles carry the highest UL 2218 impact rating, withstanding 2-inch steel ball dropped from 20 feet. This qualifies for insurance premium discounts of 15-25% in Oklahoma.
- 130 mph Wind Warranty: Owens Corning warrants Duration shingles against wind damage up to 130 mph when installed with 6 nails per shingle and proper fastener placement.
