Colorado homeowners interested in upgrading their asphalt roof shingles often ask, what are the best Class 4 shingles?
There is no single best brand of Class 4 shingles. Manufacturers include Owens Corning, GAF, CertainTeed, Malarkey, and more. Asphalt shingles are manufactured to meet industry-defined standards. Impact resistant shingles with a Class 4 rating are designed and tested to provide better quality, durability, and overall resistance to hailstorms, as determined by independent testing company Underwriter Laboratories (UL). UL 2218 is the Class 4 hail rating for asphalt roofing shingles that are tested by dropping a 2-inch steel ball multiple times from 20 feet, simulating hail.

Beyond hail, strong winds can have a significant impact on a roof. Wind that hits the side of a home will travel up and over the roof creating pressure on the roofing materials. This uplift pressure may lift shingles off a roof deck. Class 4 hail resistant shingles are also designed to be wind resistant shingles, able to withstand high winds up to 130 miles per hour. The American Society for Testing Materials (ASTM) provides these shingles with the ASTM D7158 for wind resistance.
Impact resistant shingles (also referred to as Class 4 shingles) are roofing products specially designed to withstand extreme winds, snow, and hail damage. Class 4 shingles are manufactured with an SBS (styrene-butadiene-styrene)-modified asphalt formula, which is also called rubberized asphalt. These impact resistant shingles earn an impact resistance rating by UL, specifically the UL 2218 classification, which is the highest impact resistance rating.
