Same lab wind classes, different wind warranty

GAF lists ASTM D3161 Class F and ASTM D7158 Class H for its Royal Sovereign 3-tab shingle and the same two classes for its Timberline HDZ architectural shingle.^{[1, 2]} Owens Corning lists the same classes for its Supreme 3-tab shingle.^[10]

The warranty is where they split. Every 3-tab line below is warranted against wind up to 60 mph, and that coverage lasts 5 years. The architectural lines start at 110 mph or more and the coverage lasts 15 years. Higher speeds require the same brand's starter strips, ridge caps or extra nails.^{[3, 4, 5, 6]}

Owens Corning and TAMKO also void wind coverage when the National Weather Service or another reputable agency records winds above the rated speed in the county; TAMKO also counts adjoining counties.^{[4, 6]}

What "lifetime" means

A lifetime warranty is not unlimited. GAF applies it to single-family detached homes owned by individuals, for as long as the original owner (or one qualifying second owner) owns the home.^[3] Owens Corning applies it to single-family detached homes where the roof owner lives in the home, for as long as that owner owns it.^[4] After the non-prorated period, coverage is reduced each year. Tear-off and disposal are not covered under GAF's warranty, even in the first years.^[3]

Installation

GAF lists 79 Royal Sovereign shingles and 316 nails per square (100 square feet), against 64 Timberline HDZ shingles and 256 nails.^{[1, 2, 9, 10]}

Common questions

Are architectural shingles the same as dimensional shingles?

Yes. The National Roofing Contractors Association defines a dimensional shingle as Two or more strips of material laminated together; also called a laminated or architectural shingle.^[8]

Do 3-tab shingles have a lower wind rating?

Not in the lab: GAF and Owens Corning list the same wind classes for their 3-tab shingles as for architectural ones. The wind warranty is lower: 60 mph for 5 years.^{[1, 3, 10]}

Are 3-tab shingles still made?

Yes. GAF, Owens Corning, CertainTeed and TAMKO all list a 3-tab line in their current warranties.^{[3, 4, 5, 6]}

How long is the full-coverage period?

For the brands above, 5 years on 3-tab lines and 10 years on standard architectural lines, before coverage starts to be prorated.^{[3, 4, 5, 6]}
