Hail
Alberta's costliest weather
Insurance Bureau of Canada puts hail damage in Alberta at about $6 billion over the five years to 2025. 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. Big enough hail can still dent metal; the material warranty excludes hail larger than 38 mm (1.5 in), and storm damage is a matter for your home insurance.
