Is GAF the best shingle?

GAF is considered one of the best shingle brands and is the largest selling shingle brand in North America, but whether it is the absolute best depends on your criteria for best. GAF is best in terms of market share, availability, contractor network, and warranty options. GAF Timberline HDZ is the most installed architectural shingle in the US and offers excellent balance of appearance with Dual Shadow Line, durability with Dura Grip adhesive for 130 mph wind warranty, StainGuard Plus algae protection for up to 25 years, and competitive pricing. GAF offers strong warranties including the Golden Pledge limited warranty with up to 50-year material and 25-year workmanship coverage when installed by a GAF Master Elite contractor. However, other brands may be best for specific needs. Malarkey is often considered better for impact resistance and sustainability with its polymer-modified asphalt and Class 4 impact rating. Owens Corning Duration is considered best for SureNail technology that provides excellent fastening. CertainTeed Landmark is considered best for color depth and heavier weight. For most homeowners, GAF is among the best for overall value, wide availability, good looks, and strong warranty support. For hail-prone areas, Malarkey Legacy or GAF Timberline AS II with Class 4 rating may be better. So GAF is one of the best and best-selling, but not necessarily the best for every specific performance criteria.
