Supreme® shingles add value, weather-resistance and curb appeal to your home at an affordable price. In fact, they were recently rated by a popular consumer buying guide as a "Great Buy". Additional weathering-grade asphalt and tough, Fiberglas® mat construction give them superior weatherability. Supreme shingles are backed by a 60 mph wind-resistance warranty and carry UL Fire and Wind Resistance Ratings. Plus, they’re specially treated to resist roof discoloration due to algae growth, and carry a separate 10-year algae-resistance warranty.
