America's Top Roofing Shingle Brands Compared

There is no single best brand. GAF is the top choice for contractor availability and market support. Owens Corning leads in color technology and options. CertainTeed offers premium quality and the strongest warranty programs. IKO delivers solid value at a lower price point. Atlas is the top pick for hail-prone regions with its Scotchgard protector. TAMKO is the best budget-friendly option. The right brand depends on your priorities, climate, and which certified contractors are available in your area.

Both are excellent manufacturers with strong product lines. GAF has the wider contractor network and the largest market share. Owens Corning has better color technology with the TruDefinition line and a strong reputation for innovation. The decision often comes down to which brand your preferred contractor is certified with, since both GAF Master Elite and Owens Corning Platinum Preferred programs offer enhanced warranties that only apply when their certified contractors do the installation.

CertainTeed's SureStart Plus and GAF's Golden Pledge are the strongest warranty programs in the industry when installed by certified contractors. Both offer 50-year non-prorated coverage with workmanship guarantees. Standard manufacturer warranties across all six brands are fairly similar at 25-30 year limited lifetime. The key difference is the enhanced warranty you get through certified contractor installation, which covers both materials and labor.

TAMKO and IKO typically have the lowest pricing among the six major brands, with installed costs roughly 10-15% below GAF and Owens Corning for comparable product tiers. However, cheapest is not always most economical. Warranty coverage, contractor availability, and long-term durability all factor into total cost of ownership. A slightly more expensive shingle with a stronger warranty and better contractor support can cost less over the life of the roof.

Insurance companies care about shingle class ratings, particularly Class 4 impact resistance, not the brand name. All six major brands offer Class 4 impact-resistant shingles that qualify for insurance discounts of 10-35% in many states. What matters to insurers is the UL 2218 rating and wind resistance certification, not whether the shingle is made by GAF, Owens Corning, or any other manufacturer.

Atlas StormMaster Shake and GAF Timberline AS II are among the highest-rated shingles for hail resistance. CertainTeed NorthGate and Owens Corning Duration FLEX also perform well in UL 2218 Class 4 impact testing. Atlas is particularly notable because all StormMaster products include Scotchgard Protector from 3M, which also prevents algae staining. For homeowners in hail-prone states like Texas, Nebraska, Colorado, and Oklahoma, any of these options will qualify for insurance discounts.
