A roof is a very important, as well as expensive, feature of your home. Maintaining your roof is one of the best ways to protect you, your family and all you keep under that roof. Atlas Protects™ is more than a slogan as the company, with decades of experience, has the products and advice to help you reduce roof maintenance. Atlas Roofing StormMaster® Slate and Shake shingles have high performance features that can help resist the many hazards that a roof can face each year. This strength means you, the homeowner, may face fewer maintenance issues. Master The Storms Underwriter’s Laboratory, UL 2218 is a national standard rating system for impact resistance that rates roofing materials from Class 1 through 4. A Class 4 rating indicates the highest level of impact resistance. Atlas StormMaster® Shake and StormMaster® Slate shingles have both earned Class 4 ratings. These shingles are strong enough to earn the Class 4 rating because they are manufactured with Styrene Butadiene Styrene (SBS), a rubberized polymer that gives them incredible flexibility and durability. The rubber-like quality gives StormMaster® shingles the highest protection against impact from hail, which can fracture shingles. StormMaster® shingles are also high wind-rated which helps resist blown off shingles. Loss of shingles due to high velocity wind could lead to wind-driven rain flooding a house. StormMaster® Slate and Shake come with a Limited Wind Warranty that protects a roof up to 130 mph. Black streaks on a roof not only look dirty, but also make a house appear old and reduce its curb appeal. Black streaks are the result of algae growth. Atlas StormMaster® shingles are built with the power of Scotchgard™ Protector, which helps a roof retain its color for years by resisting those black streaks. Atlas certifies this by having regular third-party laboratory testing to ensure an even spread of the Scotchgard™ protective copper granules. Both lines of StormMaster® are backed by an Atlas Lifetime Limited Warranty against the black streaks caused by algae. The Final Word In Warranties StormMaster® shingles are warranted against manufacturing defects with the exclusive Atlas Lifetime Limited Warranty for 20 years. That is the length of the Premium Protection Period for the initial non-prorated labor and material coverage of every new StormMaster® Slate roof installed with the Atlas Signature Select® System. StormMaster® shingles give a house what it needs most; an incredibly impressive appearance and security that shelters everything and everyone under the roof.
