Calgary-Specific Considerations
Hail Resistance
Calgary is in Canada’s “Hailstorm Alley.” If you’re replacing your roof anyway, upgrade to Class 4 impact-resistant shingles. They cost 20-30% more but:
- Last significantly longer in hail events
- Qualify for insurance discounts
- Better warranty protection
Ice & Water Shield
Calgary building code requires ice and water shield at eaves, valleys, and around penetrations. Budget $400-$800 for this component.
Ventilation
Proper attic ventilation extends roof life significantly. Include ridge vents and soffit vents in your quote.
