GAF is the largest roofing manufacturer in North America and Timberline HDZ is the best-selling shingle in the country. Most contractors default to GAF because of availability, name recognition, and the contractor certification program.
Pros: Widest availability at distributors nationwide, largest color selection, LayerLock technology for a 130 mph wind rating with just 4 nails, strong brand recognition with homeowners, and the GAF Master Elite certification program gives contractors marketing advantages.
Cons: Slightly thinner profile than Owens Corning Duration, some contractors report more granule loss in the first year, and the warranty requires using GAF accessories for full coverage.
Best for: Contractors who want the most recognized brand and easiest sell to homeowners. The HDZ is a reliable everyday shingle that works on most residential projects.
Owens Corning is the second largest manufacturer and the Duration line is their flagship product. It is known for its thicker profile and SureNail technology strip that provides a visible nailing zone.
Pros: Thickest profile of the three giving a more dimensional look on the roof, SureNail technology strip makes installation faster and more consistent, 130 mph wind rating, and excellent color options including the popular Driftwood, Onyx Black, and Estate Gray.
Cons: Higher price point than GAF and CertainTeed, heavier per square which means more labor on steep roofs, and slightly less availability in some regional markets.
Best for: Contractors who want to offer a premium product at a mid-range price point. The thicker profile helps close deals with homeowners who want their roof to look substantial.
CertainTeed is owned by Saint-Gobain and the Landmark line has been a staple in residential roofing for decades. It sits at a competitive price point between GAF and Owens Corning.
Pros: Excellent mid-range price, good color palette especially in earth tones, Max Def colors provide a premium look, strong warranty program, and the Landmark Pro upgrade offers a thicker profile at a modest price increase.
Cons: Lower wind rating at 110 mph vs 130 mph for GAF and OC, smaller market share means less brand recognition with homeowners, and limited availability in some areas.
Best for: Budget-conscious projects where you need a quality shingle at a competitive price. Also a strong choice in the Southeast and Midwest markets where CertainTeed has a strong distributor network.
Each manufacturer offers step-up products for homeowners who want better performance or aesthetics:
| Tier | GAF | Owens Corning | CertainTeed |
|---|---|---|---|
| Entry | Timberline HDZ ($90-110/sq) | Duration ($100-130/sq) | Landmark ($95-120/sq) |
| Mid | Timberline NS ($110-140/sq) | Duration Storm ($120-150/sq) | Landmark Pro ($110-135/sq) |
| Premium | Camelot II ($160-200/sq) | Berkshire ($180-220/sq) | Grand Manor ($200-250/sq) |
| Designer | Grand Sequoia ($200-260/sq) | Woodcrest ($150-190/sq) | Presidential ($250-320/sq) |
The honest answer is that all three manufacturers make quality shingles and you will not go wrong with any of them. The best choice depends on your market, your distributor relationships, and what your customers care about:
Choose GAF if you want the easiest name to sell, widest availability, and the Master Elite certification marketing benefits. Most homeowners have heard of GAF.
Choose Owens Corning if your customers care about aesthetics and want the thickest, most dimensional look. The SureNail strip also makes installation more consistent for your crews.
Choose CertainTeed if price is the primary concern or if you have a strong CertainTeed distributor in your area. Landmark is a solid shingle at a competitive price.
Many successful contractors offer all three and let the homeowner choose based on color preference and budget. Presenting options with clear pricing builds trust and closes more deals.
