Hail-resistant roofing built for Colorado's worst storms. Class 4 is the highest impact-resistance rating under the UL 2218 standard — the upgrade that helps protect your home and may qualify for insurance premium discounts. More than 20 years of experience in shingles and metal roofing (flat iron). Free inspection in 24 hours.
Class 4 is the highest impact-resistance rating under the UL 2218 standard, the test used to measure how well a roofing material stands up to hail. During testing, a 2-inch steel ball is dropped from 20 feet onto the roofing sample; a Class 4 rating means the material shows no cracking or rupture. In Colorado's hail country, a Class 4 impact-resistant roof is the upgrade homeowners choose to help their roof survive severe storms.
Colorado is one of the most hail-prone states in the country, and many Colorado insurers offer premium discounts for roofs with a Class 4 (impact-resistant) rating. Whether a discount applies — and how much — depends on your specific policy and insurer, so we recommend asking your insurance agent. We do not guarantee any premium change or insurance outcome; we install the roof to the Class 4 standard and document it for your insurer.
Impact-resistant asphalt shingles engineered with modified polymers for flexibility and hail resistance. A Class 4 shingle roof gives you a traditional look with the highest UL 2218 impact rating and a wide range of colors.
Standing seam, corrugated, and flat metal panel (flat iron) roofing in steel, aluminum, and coated finishes. Metal naturally resists hail impact and typically earns a Class 4 rating — durable, long-lasting, and low-maintenance for Colorado homes.
Both can meet the Class 4 standard. Shingles offer a classic look and lower upfront cost; metal offers a longer lifespan and the strongest hail resistance. We help you choose based on your home, budget, and your insurer's requirements.
