More Than Just Shingles
The Complete GAF Lifetime Roofing System
A roof is more than just shingles. The GAF Lifetime Roofing System uses 6 integrated layers that work together to protect your home and unlock industry-leading warranty coverage.
Why a Complete System Matters
Most roofers install shingles and call it a day. We install a complete, integrated system — because every layer plays a role in keeping water out, reducing energy costs, and qualifying you for the strongest warranties in roofing. When all 6 layers work together as designed by GAF, you get maximum protection and the GAF Golden Pledge warranty.
Roof Deck Protection
The foundation of every great roof. GAF FeltBuster synthetic underlayment covers your entire roof deck, creating a water-resistant barrier between the wood decking and your shingles. Unlike traditional felt paper, synthetic underlayment won't wrinkle, tear, or rot — giving you a smoother, more durable base layer.
- Prevents moisture infiltration to the deck
- Lies flat for cleaner shingle installation
- Won't tear or wrinkle like felt paper
Leak Barrier
Your most vulnerable areas get extra protection. GAF WeatherWatch or StormGuard self-adhesive leak barriers are installed along eaves, valleys, around skylights, and anywhere water tends to collect. This layer seals around nail penetrations to prevent ice dam and wind-driven rain leaks.
- Self-sealing around nails and fasteners
- Protects valleys, eaves, and penetrations
- Prevents ice dam damage
Starter Strip Shingles
The first row matters most. GAF ProStart Starter Strip shingles provide a factory-applied adhesive sealant along the eaves and rakes, securing the first course of shingles against blow-offs. This eliminates the old-school practice of cutting shingles to use as starters — saving time and improving performance.
- Factory sealant for superior wind resistance
- Consistent, precise installation
- Protects the most wind-vulnerable edge
Lifetime Shingles
The visible layer that protects and beautifies your home. GAF Timberline HDZ shingles are the #1 selling shingle in North America — with a dimensional wood-shake look, LayerLock technology for 130 MPH wind resistance, and StainGuard Plus protection against blue-green algae. Available in dozens of colors to match your home.
- 130 MPH wind warranty (LayerLock)
- StainGuard Plus algae protection
- #1 selling shingle in North America
Ridge Cap Shingles
The finishing touch at the peak. GAF TimberTex or Seal-A-Ridge cap shingles are specially designed for hips and ridges — the most visible part of your roof. They provide a polished, dimensional appearance while creating an extra seal along the ridge where two slopes meet.
- Designed specifically for ridge lines
- Adds visual depth and dimension
- Extra seal at the most exposed point
Attic Ventilation
The hidden layer that makes everything last. Proper attic ventilation (using GAF Cobra ridge vents and soffit intake) prevents heat and moisture buildup that can warp decking, cause ice dams, and dramatically shorten shingle life. A balanced ventilation system keeps your attic dry and your energy bills lower.
- Extends shingle and deck lifespan
- Prevents ice dams in winter
- Reduces cooling costs in summer
