The crew nailed the last ridge cap on a gray November afternoon, and that night the wind came up hard off the water. Lying awake, you wonder whether brand-new shingles are stuck down yet. With Owens Corning Duration, the warranty answers that one plainly. They may not be, and the company says so in writing.
Eight shingles under one Duration name
Owens Corning sells Duration as a series. The table at the end of its Platinum Protection document, dated August 2026, puts TruDefinition Duration, Duration MAX, Duration COOL, Duration COOL Plus, Duration Designer, Duration FLEX, Duration STORM and Duration Premium in a single row. Most coverage terms below apply across the whole family. Hail ratings are not in the warranty, so ask for the impact class of the exact product in writing, and see our guide to Class 4 and other impact ratings.
The standard shingle in the series is TruDefinition Duration. Owens Corning’s 2016 data sheet for it gives a nominal size of 13 1/4 x 39 3/8 inches, 5 5/8 inches of each course left exposed, and 64 pieces in three bundles. Look closely at the coverage line. Those three bundles cover 98.4 square feet, a little short of a true 100-square-foot square, so the bundle count on a quote may run slightly higher than the roof’s area suggests. The sheet’s standards list includes Class F wind resistance under ASTM D3161, Class H under ASTM D7158, and Class A fire resistance. We found no Owens Corning document listing a weight per square for Duration.
What SureNail changes on the roof
TruDefinition Duration carries what Owens Corning calls patented SureNail Technology, covered by U.S. Patent 7,836,654 according to the 2016 data sheet. County Roofing Systems in Melville, which says it is an Owens Corning Platinum Preferred contractor, describes it as a fabric strip in the nailing area that resists nail pull-through. The company says it gives installers a wide nailing zone that is hard to miss.
The 2016 data sheet listed a 10-year algae warranty and 10 years of non-prorated TruPROtection coverage on the standard warranty. The current Platinum document changes the algae term, and the ridge cap section below explains how.
How Duration earns 130 or 160 mph of wind coverage
The August 2026 warranty table gives the Duration series 130 mph of wind protection for a 15-year wind warranty period. Duration is also the only line in that table with an enhanced rating, 160 mph, and Owens Corning spells out exactly what earns it. The roof must use Owens Corning starter shingles on both the eaves and the rakes, qualifying Owens Corning hip and ridge shingles, Owens Corning synthetic underlayment (or its self-adhered ice and water barrier over the whole deck), plus either that ice and water barrier or VentSure ventilation. It must also follow the company’s Enhanced Wind Application Instructions, including the fastening pattern. Miss any piece and the roof drops back to 130 mph coverage.
Fall jobs come with a catch. The warranty says Owens Corning shingles seal with “direct warm sunlight for several days.” A roof laid during cool weather can sit unsealed until temperatures climb, and blow-offs before the bond forms are not the company’s responsibility. A roof finished in late fall can wait longer for that bond than one finished in summer. Owens Corning also says it decides whether winds exceeded the rating from National Weather Service or similar records for your county.
Algae coverage depends on which ridge caps go on
Algae-resistant Duration carries up to a 25-year algae warranty, with the first 15 years non-prorated, under the August 2026 terms. The 25 years apply only when the ridge is capped with a qualifying Owens Corning hip and ridge product, which the warranty lists as DecoRidge, DuraRidge, ImpactRidge, ProEdge or RIZERidge. Put any other ridge cap on and coverage shrinks to a decade, with only the first year non-prorated. The coverage targets brown-black streaks from Gloeocapsa magma only. Mold, lichen and green algae are excluded. Algae resistance is sold regionally, so the bundles need to say AR.
Owens Corning adds a note for South Shore and North Fork homes alike. Near the coast, copper washing off algae-resistant shingles can corrode aluminum gutters. Its advice for those areas is vinyl, and it refuses responsibility for aluminum gutter damage. If your gutters are being replaced with the roof, raise it with the roofer and see our gutters page.
What a Duration roof costs on Long Island
County Roofing Systems puts Duration at $450 to $600 per square installed. On a 20-square roof that works out to $9,000 to $12,000, and Duration FLEX adds about $50 to $75 a square. Its HDZ comparison puts the shingles alone at $3,800 to $4,400 for 22 to 24 squares, the same range it gives for GAF. Duration is also one of the three shingles that LI Roofing Co., based in North Massapequa, says its crews put on most often.
Some Long Island contractor posts still describe a 10-year algae term for Duration. Under the August 2026 warranty, 10 years is what you get when the ridge caps are not Owens Corning. Ask which term applies to your quote. Our three-brand comparison sets Duration beside GAF and CertainTeed, and the basics of 3-tab versus architectural shingles live on the asphalt shingles guide.
Questions for a roofer quoting Duration
- Which Duration exactly? TruDefinition Duration, FLEX, STORM and Designer are different products, so ask for the impact rating of the one on the quote.
- Is the hip and ridge an Owens Corning product from the warranty list? That one line decides whether the algae term is 25 years or 10.
- Will you install for the 160 mph enhanced wind rating, with starter on the rakes as well as the eaves?
- Is the shingle algae resistant, and are my gutters aluminum?
- Which warranty will you register? Owens Corning’s Platinum Protection requires a Platinum Preferred contractor and registration within 60 days, and our roof warranty guide walks through what it covers.
