Why it works in Edmonton
Edmonton roofs swing through wide temperature ranges, heavy spring snow, and gusty Prairie winds. Timberline HDZ’s Advanced Protection asphalt stays flexible through freeze-thaw cycles, while the StrikeZone nailing area and Dura Grip sealant help the roof resist wind uplift. Pair it with a GAF leak barrier at the eaves to guard against ice-dam backup.
