Due to extreme coastal winds, local contractors typically implement 'storm nailing' (using 6 nails per shingle instead of 4) and manual hand-sealing with asphalt cement. This specialized labor adds approximately 5-10% to the total project cost compared to inland Canadian cities.
As of 2026, the City of St. John's charges a permit fee of $9.00 per $1,000 of construction value for projects up to $100,000. For an average $12,450 roof replacement, the permit fee would be approximately $112.05.
The ideal window is between late June and early September. Shingles require consistent temperatures above 10°C for the thermal sealant strips to properly bond; installation in colder months significantly increases the risk of shingle blow-offs during winter gales.
While not legally required, they are the local standard. Architectural shingles are rated for winds up to 210 km/h (130 mph), whereas basic 3-tab shingles are only rated for 100 km/h (60 mph), making the latter highly susceptible to damage in NL's climate.
