Roofing in Qualicum Beach

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.

The wind figure 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. We use tighter edge fastening patterns and heavy-duty closure details to withstand strong coastal winds.

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. Qualicum Beach uses a different requirement than the RDN, so we confirm the rules directly with the Town.

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 we build a waterfront property above that baseline.

Our 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.
