Owens Corning Duration Shingles: SureNail Technology & Storm Performance

Published: 2026-04-12

Owens Corning Duration Series shingles incorporate SureNail Technology, a patented triple-layer fabric reinforcement in the nailing zone that provides superior tear resistance and grip strength. The visual SureNail strip — available in three contrasting colors — enables both installers and inspectors to immediately verify proper fastener placement.

SureNail Technology

Unlike standard architectural shingles that rely on a single layer of asphalt-saturated fiberglass mat at the nailing zone, Duration shingles feature a woven fabric reinforcement sandwiched between two asphalt layers. This tri-laminate construction resists nail pull-through forces that cause shingle blow-off during wind events. Independent testing shows that Duration shingles with SureNail require approximately 40% more force to pull a nail through compared to standard architectural shingles without fabric reinforcement.

Storm Performance Characteristics

Duration shingles weigh 235 lbs per square, which is 15-20 lbs heavier than standard architectural shingles. This additional mass contributes to wind resistance through simple gravity — heavier shingles resist uplift forces more effectively. However, contractors must verify that the existing roof deck structure can support the additional weight, particularly on older homes where the original roof was designed for 3-tab shingles (190-210 lbs/square).

🛡️ Insurance & Compliance Advisory
Owens Corning Duration shingles feature SureNail Technology — a fabric-reinforced nailing zone visible in three bright colors. This visual contrast makes it easier for adjusters to verify proper nail placement during post-claim inspections. Improperly nailed shingles (nails placed above or below the nail zone) are a common basis for partial claim denial. When documenting wind damage to Duration shingles, photograph the SureNail strip to demonstrate whether nails were properly placed. Duration shingles are heavier than standard architectural shingles (235 lbs/square vs 210-225 lbs) — this additional weight contributes to better wind resistance but must be considered when evaluating structural loading on older roof decks.
