Roofing in Qualicum Beach
Qualicum Beach is one of only two communities on this coast with a dedicated row in BC Building Code Table C-2. The tabulated one-day design rain is 96 mm and the 1-in-50 hourly wind pressure is 0.53 kPa, both above the figures listed for Parksville. Town of Qualicum Beach Building Bylaw No. 903, 2024 governs building permits inside the town.
Two things make a roof here different from one twenty minutes down the highway: the code tabulates this town separately, and the Town writes its own permit rules.
The numbers the code gives Qualicum Beach
Table C-2 of the BC Building Code lists Qualicum Beach separately from Parksville, and the two rows are not identical. One-day design rain is 96 mm against 91 mm. The 1-in-50 hourly wind pressure is 0.53 kPa against 0.50 kPa. January design temperatures are minus 7 and minus 9 degrees against minus 6 and minus 8. Annual rainfall matches at 1,200 mm, ground snow load matches at 2.0 kPa, and both sit at 3,200 degree-days.
The wind figure is the one that shows up in the work. Six per cent more hourly wind pressure sounds like nothing until it is applied to a rake edge, a ridge cap or an exposed gable on a lot with open water in front of it. Edge fastening patterns and closure details are where that margin gets spent.
A separate bylaw, and roofing is not named in it
Qualicum Beach is an incorporated town, so the Regional District of Nanaimo permit lists do not apply inside the boundaries. The Town works from Building Bylaw No. 903, 2024.
The exemption list at Section 3.3 does not mention roofing anywhere. What it does include is repair and maintenance of lawfully-conforming structures where the level of life safety and building performance is not decreased below the level that already exists, exclusive of structural alterations and remediation as a result of a previous deficiency.
A like-for-like re-roof sits inside that clause. A re-roof that alters structure, or that remedies an earlier deficiency, is expressly outside it. That is a different test from the RDN's, and the answer is confirmed with the Town rather than assumed from a neighbouring jurisdiction.
What that means on a roof here
Exposure runs from sheltered lots inside the town grid to properties looking straight across the Strait of Georgia. The tabulated figures are a town-wide baseline, not a description of any particular lot, and a waterfront property gets specified above that baseline rather than to it.
The assessment covers the same ground either way: slope measured on the roof, deck condition where it can be seen, existing ventilation against the 1/300 of insulated ceiling area the BC Building Code sets, and the condition of every flashing, closure and edge detail facing the prevailing weather.

Roof work covered here
- Flat and low-slope roofingMembrane roofing for garages, additions and modern rooflines, specified to the slope range the BC Building Code allows and detailed so water actually leaves.
- Roof repairs and maintenanceLeak tracing, flashing and valley repair, moss management and gutter clearing — the work that decides whether a roof reaches its rated service life.
