- Chinook wind damage – Rapid temperature swings (up to 30°C in hours) lift shingles and crack seals, creating entry points for water.
- Ice dam formations – Freeze-thaw cycles cause water to back up under shingles, penetrating roof decking within 24-48 hours.
- Hail impact damage – Golf ball-sized hail (common June-August) punctures shingles and dents metal roofing, compromising waterproof barriers.
- Snow load stress – Heavy March snowfalls (exceeding 60cm) strain roof structures, causing sagging and potential collapse.
- Flash freeze cracks – Temperature drops from +15°C to -20°C split roofing materials and open existing weak points.
