How long do asphalt shingle roofs last in B.C.?
Asphalt shingle roofs are often discussed in roughly 15- to 30-year service ranges, but B.C. exposure and installation can move a roof toward either end. Product warranty length is not a prediction of installed life. The decision should also account for broad granule loss.
Coastal moisture changes ageing
Shade, moss, debris and slow drying can keep shingle edges wet. Valleys and north-facing slopes may age differently from sunny roof sections.
Interior and northern climates add extremes
Strong UV, summer heat, winter cold, snow and freeze-thaw cycles stress seal strips, flashings and exposed edges.
Installation details remain decisive
Nailing, underlayment, ventilation, deck condition and flashings often determine whether a roof reaches its expected range.
Details worth checking
- Curling, cracking or brittleness
- Broad granule loss
- Unsealed or wind-lifted tabs
- Repeated leaks at different areas
- Soft decking or attic staining
- Repair history and product availability
