The layers of a GAF roofing system
- Leak barrier (such as GAF StormGuard) at the eaves, valleys and around chimneys, to help stop leaks from wind-driven rain and ice dams.
- Roof deck protection (such as GAF FeltBuster, Deck-Armor or TigerPaw) over the whole deck, to help keep moisture off the wood.
- Starter strip shingles along the edges, to help guard against shingle blow-offs.
- GAF Lifetime shingles, such as Timberline HDZ. All Timberline shingles and GAF designer shingles qualify.
- Attic ventilation: ridge and off-ridge vents that let the attic breathe. See attic ventilation.
- Rooftop accessories such as pipe boots.
- Ridge cap shingles, the final layer that protects the hips and ridges.
How the system affects your warranty
- GAF Lifetime shingles on their own carry GAF's standard limited warranty.
- GAF Roofing System Limited Warranty: a GAF Lifetime shingle plus at least 3 qualifying GAF accessories qualifies for Lifetime limited coverage on the shingles and the qualifying accessories.
- GAF System Plus Limited Warranty: also requires at least 3 qualifying accessories, installed by a GAF certified contractor, and extends GAF's non-prorated Smart Choice protection period.
- Higher tiers (Silver Pledge, Golden Pledge) need more accessories and higher GAF certification levels.
On top of GAF's coverage, every full Homcertin roof replacement includes our own 10-year labor warranty. See all warranties.
“Lifetime” refers to the length of GAF's warranty coverage as long as the original owner(s) of a single-family detached home (or an eligible second owner) owns the property; other owners and structures receive different coverage. See GAF's roofing system warranty page and the warranty documents for complete terms and restrictions. We confirm which GAF warranty your roof qualifies for in your written estimate.
Why a full system matters
Most leaks start where parts of the roof meet: edges, valleys, chimneys, vents and walls. Using matched GAF components at every one of those spots, and installing them together, is what makes the roof perform as one system and what qualifies it for the stronger GAF warranties. Ask for this in any estimate you compare. See our roof replacement page and cost guide.
