Atlas Signature Select® is a cohesive roofing system, who's components are specifically chosen to work together. That's why we'll double your roof's Premium Protection Period from a standard 3 or 5 year limited warranty to a 6 or 10 year limited warranty respectively, when you install all Atlas qualifying components. All Atlas shingle products are eligible for this premium protection upgrade by installing qualifying components. Atlas Signature Select® features a 3-tiered approach to accommodate the most discerning taste and meet any budget.
