Price positioning
GAF does not publish installed pricing. Only a written, itemized quote from a certified contractor that lists shingle line, underlayment, ventilation components, and labor is a reliable basis for comparison.
Certified installer network
Installed through independently owned and operated contractors holding GAF certification tiers, with Master Elite as the top tier required for the longest published workmanship coverage under the Golden Pledge program.
Maintenance considerations
- Attic ventilation must meet GAF's published specification for the shingle warranty to remain intact on many product lines.
- System registration must occur inside the published window to activate extended workmanship coverage.
- Fastening pattern and nail placement must match the published installation instructions to keep the stated wind rating valid.
- Repairs made outside the certified contractor network should be documented, since undocumented alterations can affect a claim review.

Frequently asked questions
What is the difference between Timberline HDZ and UHDZ?
UHDZ is a thicker, more dimensional shingle with a higher published wind-rating ceiling when installed to GAF's specification. HDZ is the higher-volume line at a lower price point.
How long is the GAF workmanship warranty?
Up to 25 years is published under the Golden Pledge program, but only when a GAF Master Elite contractor installs the roof and registers it inside the published window.
Does GAF cover algae staining?
Qualifying shingle lines publish StainGuard Plus algae-resistance coverage for a stated term. Confirm the term on the specific product and document tied to your shingle line.
What wind rating do GAF shingles carry?
Published wind ratings vary by shingle line and by the starter strip and fastening system used, up to 130 mph on qualifying installations. Ask your contractor which rating applies to your installed configuration.
Is Royal Sovereign as durable as Timberline?
Royal Sovereign is a 3-tab shingle with shorter published material coverage and a lower wind-rating ceiling than the Timberline architectural lines. It is priced as GAF's value tier.
Can I transfer the GAF warranty if I sell my house?
GAF publishes a limited one-time transfer within a stated window after original purchase, with conditions. Check the transfer clause in the specific warranty document issued for your roof.
