Material Warranty pillar — shingle warranty class, separate from labor

The Material Warranty pillar captures the warranty class of the shingle being installed, as documented in the manufacturer's product warranty. Modern asphalt shingles typically ship with a 25-year, 30-year, or lifetime limited material warranty, and manufacturers sometimes offer enhanced warranties (GAF Golden Pledge, Owens Corning Platinum Protection, CertainTeed SureStart PLUS) when the contractor is certified at the right tier and installs a compatible full system. Vfane displays this pillar as Claimed because the warranty class depends on the specific shingle line the contractor quotes, not just on the contractor's business profile. "Lifetime" typically means the warranty lasts as long as the original homeowner owns the home — transferability to subsequent owners varies by manufacturer and tier, and prorated coverage after a certain number of years is common. One Vfane rule: Material Warranty is always shown separately from Labor Warranty. Combining them into a single "warranty" number hides which side — the manufacturer or the contractor — is actually responsible if something goes wrong. Homeowners weighing this pillar typically check the manufacturer's warranty document directly for transfer and proration terms.
