In Vancouver and the Lower Mainland, shingle damage is primarily driven by the wet coastal climate, heavy rain, and wind. Homeowners should look for the following visual signs of damaged shingles:
- Curling edges that lift and allow water to get underneath.
- Missing granules which leave the underlying material exposed.
- Cracks or bald spots caused by regional weather and thermal expansion.
- Shingles that are loose or failing to adhere properly.
- Significant moss growth, which can lead to root penetration if not removed.
- Missing tabs or entire sections of shingles, often caused by coastal wind uplift.
Identifying these signs early through safe ground-level visual inspections or professional evaluations is critical to preventing leaks and structural damage. Local factors such as freeze-thaw cycles and storm-related wear also contribute to the deterioration of asphalt shingles in this region.
