June 2020
The storm that named Airdrie
Insurance Bureau of Canada put the June 13, 2020 hailstorm over Calgary, Airdrie, Rocky View County and the surrounding area at almost $1.2 billion in insured damage, the fourth most expensive insured natural disaster in Canadian history at the time. 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. Large hail can still dent metal, and the material warranty excludes hail larger than 38 mm (1.5 in).
