EPDM Roofing in Calgary's Climate
EPDM is a synthetic rubber membrane, and its biggest strength in Calgary is cold-weather flexibility. It stays pliable through deep January cold snaps and the rapid chinook swings that follow, which is why it has a long track record on commercial roofs across the prairies.
- Black vs. white: black EPDM absorbs heat, which helps shed snow and ice; white EPDM reflects summer sun but costs more and shows dirt.
- Seams are the detail that matters: EPDM seams are taped rather than welded, so we use factory-applied seam tape where possible and check laps during maintenance visits.
- Hail: thicker 60 or 90 mil sheets over a cover board handle impact better and are simple to patch if punctured.
- Ballasted systems: stone ballast adds weight, so we confirm the structure can carry it alongside Calgary snow loads.
