Storms
Hail and heavy rain in one evening
On June 15, 2025 a thunderstorm brought hail to Sherwood Park, and Environment and Climate Change Canada reported 60 to 75 mm of rain there, the highest totals in the Edmonton area. The Edmonton-area hailstorm of August 2, 2019 caused about $90 million in insured damage. Interlock's Slate, Shake, Cedar Shingle and Mediterranean Tile aluminum panels carry a UL 2218 Class 4 impact rating, listed by Intertek under Delta Building Products. No roof is hail-proof, and the material warranty excludes hail larger than 38 mm (1.5 in).
