Serving the Regional District of Nanaimo
Roofing on the north side of the harbour
Departure Bay and North Nanaimo sit inside the City of Nanaimo, which issues building permits under Building Bylaw 2016 No. 7224. The housing stock across both was largely built between the 1950s and the 1980s, and takes wind straight off the Strait of Georgia.
Second-generation roofs
Much of this housing stock is on a second covering rather than a first, which means the deck has been open once already and the record of what was found then is usually gone. A tear-off here starts with sheathing condition rather than finishing with it, and the quote carries a per-sheet rate from the outset.
Exposure, not just rain
A 1-in-50 hourly wind pressure of 0.50 kPa and a driving-rain wind pressure of 200 Pa are the design figures for Nanaimo. On a slope facing open water, both arrive without anything in the way. Edge fastening and flashing height are what that changes; the covering itself usually is not the variable.
The permit answer inside city limits
Building Bylaw 2016 No. 7224 governs, and it names no roofing-specific exemption. The answer for a given address is confirmed with the City before the work is booked rather than inferred from what applies a few kilometres north.
Ventilation on a house of this era
Attics on this housing stock were frequently vented to the standard of the day rather than to the current one. Section 9.19.1.2 sets unobstructed vent area at not less than 1/300 of the insulated ceiling area, split across opposite sides with at least 25% at the top and at least 25% at the bottom. A re-roof is the one moment when correcting that costs almost nothing, because the roof is already open and the vents are already coming off.
