Shingle brands offering lifetime warranties include GAF, Owens Corning and CertainTeed. Tamko and Iko also carry shingles with lifetime warranties. GAF's Timberline, Specialty and Designer shingles all feature GAF's lifetime limited warranty and the first 10 years non-prorated, assuming the homeowner purchases three other qualifying GAF accessories with the shingles. The limited lifetime warranty with Owens Corning TruDefinition Duration Storm shingles includes one transfer of ownership and varying non-prorated periods depending on coverage selected.
CertainTeed's limited lifetime warranty applies only to owner-occupied residences and transfers only during a defined period that ranges from three to 10 years depending on shingle type. Tamko features its limited lifetime warranty on its Heritage Vintage and Heritage 50 wood shake shingles and IKO on its Armourshake, Cambridge LT and Crowne Slate shingles.
Considerations when selecting among shingles with lifetime warranties include the specifics of the warranty, such as transferability and number of non-prorated years. Most lifetime warranties only cover material and do not include installation or the removal or disposal of shingles with a manufacturer defect. If the company offers enhanced warranties, check and compare the cost of additional coverage. Other considerations when choosing among "lifetime" shingles are wind, algae and impact resistance. Impact resistance ratings from Universal Laboratories are not available for all shingles. The top wind-resistance for "lifetime" shingles is 130 mph, and the top algae resistance is usually 10 to 15 years.
