If you are replacing your roof in Colorado, opting for standard shingles might cost you more in the long run. Class 4 impact-resistant shingles are engineered to withstand severe weather, offering ultimate protection and financial rewards.
1. What is a Class 4 Rating?
Shingles are rated under the UL 2218 standard, which tests their resistance to impact. Under this test, steel balls of varying sizes are dropped from high distances onto the shingle. To achieve a Class 4 rating—the highest possible—the shingle must withstand the impact of a 2-inch steel ball dropped from 20 feet without cracking or splitting the backing mat.
2. Polymer-Modified SBS Technology
Premium Class 4 shingles, like those manufactured by Malarkey, GAF, and Owens Corning, utilize SBS (Styrene-Butadiene-Styrene) polymer-modified asphalt. This rubberized asphalt makes the shingle highly flexible and resilient, allowing it to absorb the energy of hailstones and bounce back without fracturing, even in cold Colorado winters.
3. Substantial Insurance Premium Discounts
Because Class 4 shingles drastically reduce the likelihood of a total roof replacement after a hailstorm, major insurance carriers offer substantial discounts on homeowner premiums. In Colorado, homeowners who install Class 4 shingles often see discounts of 15% to 28% on their annual premium, allowing the upgrade to pay for itself over time.
