GAF, Owens Corning, and CertainTeed dominate the residential shingle market, collectively accounting for roughly 75% of all shingles installed in America. All three manufacture high-quality products across every price tier, making the choice less about one brand being objectively better and more about which brand best fits your priorities, budget, and contractor relationship.

GAF, Owens Corning, and CertainTeed all make excellent shingles. The real differentiator is not the brand but the contractor certification level and resulting warranty coverage. A certified contractor installing a complete product system from any of these three brands will deliver a roof that performs well for 25 to 50 years. Focus on finding the best certified contractor in your area first, then let their brand affiliation guide your material choice.
Both are excellent. GAF Timberline HDZ is the best-selling shingle in America with a strong wind warranty. Owens Corning Duration offers similar performance with the SureNail technology strip. The best choice often depends on which brand your contractor is certified with, since certification unlocks better warranty coverage.
GAF, Owens Corning, and CertainTeed are considered the top three. GAF has the largest market share, Owens Corning is known for innovation (SureNail), and CertainTeed is known for premium aesthetics. All three make excellent products across every price tier.
CertainTeed shingles tend to be 5% to 15% more expensive than GAF or Owens Corning equivalents. Their premium products like Grand Manor and Belmont offer the most realistic slate and shake profiles. Whether the premium is worth it depends on your aesthetic priorities.
Choose based on your contractors certification level (determines warranty), the specific product wind and impact ratings for your climate, color selection, and local availability. The brand your contractor is certified with usually offers the best overall value due to enhanced warranty coverage.
