Two names dominate the asphalt shingle market in the United States: CertainTeed and GAF. Both make quality shingles. Both back their products with strong warranties. But they take different approaches to design, performance, and installation.
Picking between them comes down to your priorities. Aesthetic appeal, warranty coverage, storm performance, and upfront cost all factor in. This guide breaks down the real differences so you can make a smart call before your next roof replacement.
At a Glance: CertainTeed vs GAF
Both brands offer full lines of asphalt shingles, but each has a different strength.
- CertainTeed leads with the Landmark series, known for aesthetic appeal, deeper color options, and heavier shingle construction on its premium lines.
- GAF is the largest roofing manufacturer in the United States, and its Timberline HDZ is one of the most installed shingles in North America.
- Warranty coverage on both brands includes a limited lifetime warranty, plus extended options through certified contractor programs (CertainTeed SELECT ShingleMaster and GAF Master Elite).
- Algae resistance and wind ratings are similar across their most popular architectural shingle lines, with both offering 130 mph ratings when installed correctly.
- Cost is close on standard architectural shingles, with premium lines pulling apart in both directions.
The right pick depends less on brand loyalty and more on which specific shingle line matches your goals.
Meet the Brands
Both companies have been around for well over a century. Their reputations are earned, but the paths they took are different.
About CertainTeed
CertainTeed is a subsidiary of Saint-Gobain and has been making building products for more than 120 years. Its residential shingle line includes the Landmark series, Landmark Pro, and premium options like Presidential Shake and Grand Manor.
The brand is known for a heavier shingle profile on its premium lines, deeper shadow lines, and a wide selection of color blends. CertainTeed shingles are commonly seen on custom homes and higher-end architectural builds.
About GAF
GAF is the largest roofing manufacturer in the United States. The company has built its reputation on the Timberline family of shingles, particularly Timberline HDZ, which is now one of the most installed shingles in North America.
GAF’s strength is scale and system integration. The brand pushes homeowners toward a full roofing system built with GAF underlayment, ventilation, and accessories, all covered under a single warranty when installed by a certified contractor.
Product Lines Compared
Both brands cover the full range of homeowner budgets, from basic 3-tab shingles up to designer architectural shingles that mimic slate or wood shake.
CertainTeed Landmark and Landmark Pro
CertainTeed Landmark shingles are the brand’s most popular architectural shingle. They carry a 130 mph wind rating with the correct install, plus StreakFighter algae protection.
CertainTeed Landmark Pro steps up in weight and warranty. It offers a slightly thicker profile, deeper shadow lines, and StreakFighter Plus for stronger algae resistance. The Pro line is often chosen when curb appeal is the top priority.
Premium options like Presidential Shake and Grand Manor push into the designer category, where the shingle mimics wood shake or slate at a fraction of the weight and cost.
GAF Timberline HDZ and Premium Lines
GAF’s Timberline HDZ is the workhorse of the residential shingle market. The HDZ (High Definition Zone) features a wider nailing zone that helps installers place fasteners correctly, which improves wind performance.
GAF Timberline shingles in the HDZ line carry LayerLock technology for a stronger bond between layers, plus a 130 mph wind warranty when installed with the required GAF accessories.
GAF’s premium lines include Timberline UHDZ, Camelot II, and Grand Sequoia. These target homeowners looking for the dimensional look of slate or wood shake without the specialty pricing. Atlas Pinnacle Pristine is a common competitor in this category from another brand worth mentioning when comparing options.
Warranty Coverage
Warranty coverage is one of the biggest differences between the two brands. Both offer strong protection, but the details matter.
CertainTeed Warranties
Every CertainTeed Landmark shingle comes with a limited lifetime warranty on the shingles themselves. When installed by a qualified contractor, homeowners can access extended coverage tiers.
The strongest CertainTeed warranty is available through their SELECT ShingleMaster program, which qualifies contractors to offer higher levels of workmanship and material coverage.
GAF’s Golden Pledge Warranty
GAF offers a similar limited lifetime warranty on Timberline shingles. The premium option is the Golden Pledge warranty, available only through GAF Master Elite contractors.
It covers 50 years of non-prorated material coverage plus 25 years of workmanship coverage, which is one of the strongest warranties in the roofing industry. To qualify, the entire roofing system must be installed with GAF lifetime roofing accessories, and the installer must hold Master Elite certification.
Performance: Wind, Weather, and Algae Resistance
Performance across popular architectural shingle lines is close between the two brands.
Both CertainTeed Landmark and GAF Timberline HDZ shingles carry a 130 mph wind rating when installed correctly. Both include algae protection technology as standard on architectural shingles designed to fight the black streaks caused by gloeocapsa magma algae.
Where the brands differ:
Both also meet common energy efficiency standards on their reflective shingle lines, which can lower cooling costs in hot climates.
Cost and Value
Prices on standard architectural shingle lines are close between CertainTeed and GAF. The gap widens on premium and designer shingle options, where CertainTeed’s heavier shingle construction often pushes material cost higher.
Labor costs can also vary. A heavier shingle takes more time to install, which affects the total roof replacement price. GAF’s Timberline HDZ is designed for faster installation, which can slightly reduce labor costs on a standard architectural install.
The best measure of value is total cost of ownership. A well-installed roof with a strong warranty from either brand should last decades.

The installer, the warranty tier, and the specific shingle line matter more than the logo on the wrapper.
