Timberline AS II

Overview

GAF Timberline AS II® (ArmorShield II) shingles are engineered for homeowners who demand maximum impact resistance without sacrificing the classic Timberline look. These shingles achieve a Class 4 impact rating — the highest available under UL 2218 testing — thanks to SBS-modified asphalt that makes them remarkably flexible and resistant to cracking from hail and debris. In many areas, a Class 4 impact-rated roof may qualify homeowners for significant insurance premium discounts.

Key Features

• Class 4 impact resistance (UL 2218) — the highest impact rating available, tested to withstand a 2-inch steel ball dropped from 20 feet
• SBS-modified asphalt provides rubberized flexibility that absorbs impact energy instead of cracking or splitting
• StainGuard Plus™ algae protection with a 25-year limited warranty against blue-green algae discoloration
• 130 mph wind rating for reliable performance in severe weather and high-wind events
