When to Install a New Roof

Age Considerations

  • Asphalt shingles: Replace at 20-25 years
  • Architectural shingles: Replace at 25-30 years
  • Metal roofing: Install for 40-50 year lifespan
  • Flat roofs: Replace at 15-25 years
If you’re building new or your existing roof approaches these ages, professional installation ensures optimal performance and longevity.

Installation Solutions Built for BC Weather

Coastal Areas (Vancouver, Burnaby, Richmond)

Heavy rain, humidity, and salt air require algae-resistant shingles, marine-grade fasteners, and advanced waterproofing. Our roofing handles 1,200mm+ rainfall with efficient drainage and proper ventilation systems.

Fraser Valley (Surrey, Langley, Abbotsford)

Temperature swings from -10°C to +35°C demand impact-resistant materials and ventilation. We install roofing that handles expansion, contraction, and maintains integrity during extreme weather cycles.

Mountain Communities (Squamish, Whistler)

Heavy snow loads and freeze-thaw cycles call for reinforced structural support and metal roofing options. We install systems engineered for snow load capacity with ice-and-water barriers for enhanced protection.
