Why We Chose CertainTeed
After installing both brands for years, here are the specific reasons we made CertainTeed Landmark Pro our standard recommendation.
15-Year SureStart Period
CertainTeed's SureStart coverage lasts 15 years with a ShingleMaster installer, compared to GAF's 10 years with Master Elite. That's 50% more full-replacement protection during the critical early years.
Max Def Color Technology
CertainTeed's Max Def granules create noticeably richer, more dimensional color. Side by side on a roof, the difference in visual depth is clear. Your roof is the largest visible surface of your home.
No System Lock-In
GAF's best warranty requires their entire Lifetime Roofing System. CertainTeed gives you a strong base warranty on shingles alone, with enhancements for full-system installs. You're not penalized for mixing components.
15-Year Algae Warranty
CertainTeed's StreakFighter technology carries a 15-year algae resistance warranty vs. GAF's 10-year StainGuard. In Pennsylvania's humid summers, those extra 5 years of streak protection matter.
ShingleMaster Certification
CertainTeed's ShingleMaster program is more selective than GAF's Master Elite. It requires hands-on training (not just online modules) and represents the top 1% of roofing contractors nationally.
Premium Line Superiority
If you ever want to upgrade, CertainTeed's Grand Manor is widely considered the finest luxury asphalt shingle available. Their premium lineup (Belmont, Carriage House, Presidential) has no equal in the GAF catalog.
A Note on Fairness
We want to be transparent: as a CertainTeed ShingleMaster certified contractor, we have a professional relationship with CertainTeed. That said, every comparison point above is factual and verifiable. GAF makes quality products, and their Timberline HDZ is the best-selling shingle in America for good reason. The "best" shingle for your home depends on your specific priorities, budget, and aesthetic preferences. We're happy to install either brand and will always give you an honest recommendation based on your situation.
Where GAF Has the Edge
In the interest of honesty, here are the areas where GAF genuinely outperforms CertainTeed.
Higher Standard Wind Warranty (130 mph vs 110 mph)
GAF's Timberline HDZ comes with 130 mph wind coverage standard, compared to CertainTeed Landmark Pro's 110 mph. While both exceed typical Pennsylvania wind speeds, GAF's higher rating provides extra peace of mind for severe storm events.
Wider Nailing Zone (StrikeZone)
GAF's patented StrikeZone nailing area is wider than CertainTeed's, which can reduce installation errors. For less experienced crews, this is a meaningful advantage. Our crews are experienced enough that this doesn't affect our installation quality.
Larger Market Share & Availability
GAF is the largest roofing manufacturer in North America with ~30% market share. This means broader availability, more familiar installers, and sometimes faster delivery. CertainTeed is a close second at ~20%.
Frequently Asked Questions
Common questions homeowners ask when choosing between CertainTeed and GAF.
The Bottom Line
Both CertainTeed and GAF make quality shingles that will protect your home for decades when installed correctly. The difference is in the details: CertainTeed offers longer warranty coverage, better granule technology, and a more selective contractor program. As a ShingleMaster certified installer, we can offer the full CertainTeed warranty package that maximizes your protection.
The most important factor isn't the brand on the wrapper — it's the crew on the roof. A properly installed roof with quality materials and attention to detail will outlast a premium shingle installed by a careless crew every time.
