GAF Timberline AS II Shingles in Edmonton
GAF Timberline AS II is an SBS-modified, UL 2218 Class 4 impact-resistant architectural shingle engineered for cold, hail-prone climates — making it a strong fit for Edmonton’s freeze-thaw winters and Prairie hail.
What it is
Timberline AS II uses SBS (rubberized) polymer-modified asphalt to stay flexible in the cold and absorb impact, earning a UL 2218 Class 4 rating. It keeps the familiar Timberline architectural look while adding cold-climate toughness.
Who it’s for: Edmonton homeowners focused on hail resistance and cold-weather durability who still want a classic architectural profile.

Why it works in Edmonton
SBS-modified shingles are purpose-built for climates like ours: the rubberized asphalt stays pliable when temperatures plunge and resists cracking through freeze-thaw cycles, while the Class 4 rating addresses Edmonton’s hail exposure. This is one of GAF’s best matches for Alberta conditions.
