Why it works in Edmonton
Hail is a real risk across the Edmonton region, and UHDZ’s Class 4 impact rating is the highest UL 2218 category — the kind of shingle that can help your roof shrug off hail and may qualify for an insurance discount. Its thicker UltraMat build also adds durability through freeze-thaw and wind.
