In Vancouver’s unique climate, several common drainage issues frequently affect residential and commercial properties. Due to the region’s high annual rainfall and specific neighborhood characteristics, the most prevalent issues include:
- Clogged Gutters and Downspouts: This is a major concern in suburban areas like Surrey, where longer roof spans and heavy foliage lead to leaf accumulation and debris blockages.
- Ponding and Pooling: This is common on flat or low-slope roofs, particularly in high-density areas like Downtown Vancouver. It is often caused by intense rainfall and inadequate roof pitch.
- Rapid Runoff and Erosion: In sloped areas like North Vancouver, steep terrain can exacerbate water flow, leading to soil erosion if downspouts are misplaced or not extended properly.
- Ice Damming: Despite mild winters, freeze-thaw cycles can create ice dams that cause leaks along roof edges.
- Inadequate Pitch: Many low-slope roofs suffer from poor drainage because they lack the minimum 2 percent pitch required by the BC Building Code to ensure proper water shedding.
- Structural Signs of Failure: If drainage is restricted, homeowners may notice interior water stains, curling shingles, attic mold, or puddling water near the foundation.
