When it comes to choosing a roofing system, two names consistently rise to the top: GAF and Owens Corning. Both are industry leaders, but they have key differences that matter depending on your home, budget, and local climate.
GAF Roofing: The Industry Leader
GAF is North America’s largest roofing manufacturer, and for good reason. Their Timberline HDZ shingles are the best-selling roofing shingles in the U.S. GAF shingles are known for:
- LayerLock Technology — delivers exceptional wind resistance up to 130 mph
- StainGuard Plus — algae protection that keeps your roof looking new longer
- Golden Pledge Warranty — the strongest warranty in roofing, available only through certified contractors like Delta Power Group
Owens Corning Roofing: A Solid Alternative
Owens Corning’s Duration Series shingles are their flagship product, featuring SureNail Technology for enhanced wind resistance. They’re a quality product — but the warranty and contractor network don’t match GAF’s reach.
The Verdict: Why We Recommend GAF
As a GAF Certified Contractor, Delta Power Group installs GAF products exclusively because we believe they offer the best value, protection, and warranty coverage for homeowners across Chicago, Dallas, Columbus, Memphis, and beyond.
