8. Frequently Asked Questions
Common questions about GAF vs Owens Corning shingles
Which is better: GAF or Owens Corning shingles?
Both GAF and Owens Corning produce excellent shingles. GAF has the edge with their Timberline HDZ (America's #1 selling shingle), 25-year algae protection (vs OC's 10 years), and wider color selection. Owens Corning excels with their SureNail technology and Duration STORM impact-resistant shingles. For coastal South Carolina homes, both brands offer comparable hurricane protection. As a GAF Certified contractor, we primarily recommend GAF for their superior warranty options and proven coastal performance.
What is the difference between GAF Timberline and Owens Corning Duration?
GAF Timberline HDZ and Owens Corning Duration are both premium architectural shingles with similar performance. Timberline HDZ features LayerLock technology and StainGuard Plus (25-year algae protection), while Duration uses SureNail technology and StreakGuard (10-year algae protection). Both offer 130 mph wind warranties and lifetime limited coverage. Timberline HDZ offers more color options and is America's best-selling shingle brand.
Which brand has better warranties?
Both brands offer comparable warranty tiers. GAF's Golden Pledge and Owens Corning's Platinum Protection both provide 50-year coverage with 25 years of labor protection. The key difference is the contractor requirement - GAF requires Master Elite contractors for Golden Pledge, while Owens Corning requires Platinum Preferred contractors. Both warranties are excellent; what matters most is having a certified installer who follows manufacturer specifications.
Are GAF shingles more expensive than Owens Corning?
GAF and Owens Corning shingles are comparably priced for similar product tiers. Entry-level 3-tab, architectural, and designer shingles from both brands fall within similar price ranges. The final cost depends more on your specific product selection, roof size, and installation complexity. We provide free estimates comparing options from both manufacturers when appropriate.
Which brand is better for hurricane zones like Myrtle Beach?
Both GAF and Owens Corning offer excellent hurricane protection for coastal homes. GAF Timberline HDZ with LayerLock and Owens Corning Duration with SureNail both achieve 130 mph wind ratings. For Myrtle Beach, we recommend GAF products because of the longer algae protection (25 years vs 10 years - important in our humid climate) and our direct relationship as a GAF Certified contractor provides enhanced warranty benefits.
What is GAF LayerLock technology?
GAF LayerLock is a mechanical sealing system built into Timberline HDZ shingles. It creates a strong bond between shingle layers without relying solely on adhesive. This technology enables the 130 mph wind warranty and ensures shingles stay secure during hurricanes. The LayerLock nailing zone is clearly marked on each shingle for proper installation.
What is Owens Corning SureNail technology?
Owens Corning SureNail is a woven fabric strip integrated into Duration shingles that provides a secure nailing zone. The fabric gives nails more grip than standard shingle material, improving wind resistance. SureNail-equipped shingles qualify for the 130 mph wind warranty when properly installed by certified contractors.
Why does Weather Shield Roofing recommend GAF?
As a GAF Certified contractor, we have specialized training, direct manufacturer support, and the ability to offer enhanced warranties like Golden Pledge. We recommend GAF Timberline HDZ for most Myrtle Beach homes because of the 25-year algae protection (critical in our humid climate), proven hurricane performance, extensive color options, and our ability to provide the industry's best warranty coverage. However, we can install Owens Corning or other brands based on customer preference.
