Why Choose GAF?
GAF’s reputation isn’t accidental. Their Timberline HDZ is the #1 selling shingle in North America, engineered with LayerLock Technology that bonds shingles together for industry-leading wind resistance — critical in our region where nor’easters routinely push 60+ mph gusts. The Lifetime Limited Warranty covers shingles for 50 years, and when paired with the Golden Pledge Warranty through certified installers, your workmanship is also protected for 25 years.
Color & Style Options (2026):
Charcoal, Pewter Gray, Slate, Weathered Wood, Hunter Green (making a comeback), and the popular Birchwood for craftsman-style homes. The Timberline HDZ collection offers 20+ color blends designed to complement everything from a 1920s Doylestown colonial to new construction in Skippack.
Premium Lines We Install:
- Timberline HDZ — the architectural shingle standard
- Timberline Solar — solar-integrated roofing
- Camelot II — premium designer shingle
- Slateline — slate-look composite for historic homes
- Grand Sequoia — rugged shake-style appearance

Why Choose Dexteriors For Your GAF Install?
GAF certification is more than a logo on our truck — it’s a binding standard. Only certified contractors can install GAF systems to factory specifications AND offer the full Golden Pledge Warranty. Dexteriors holds dual certifications (GAF Certified + CertainTeed ShingleMaster), which puts us in a small minority of Greater Philadelphia roofers qualified for premium warranty coverage.
Every GAF install includes proper ice-and-water shield in valleys, eaves, and rakes (non-negotiable for our freeze-thaw climate), synthetic underlayment across the full deck, and ridge ventilation matched to your attic’s CFM requirements. No shortcuts — because shortcuts are what cause ice dams and premature failure in Northeast homes.
Your New GAF Roof, Done Right.
A GAF roof is a 25+ year investment for your home. Make sure it’s installed by certified pros who understand Northeast weather and back the work with a real labor warranty. Schedule your free, no-pressure consultation today.
We had Dexteriors replace our roof, siding, gutters, and some windows. We are so impressed by the way our home looks! It was a truly amazing experience! We had met with 5 different roofing companies before we selected Dexteriors. Dexteriors stood out above all of them.
