Common Questions

St. John's costs are roughly 10-20% higher due to the 'island tax,' where shipping materials via Marine Atlantic adds significant logistics costs. Additionally, local labor is more expensive due to specialized 'Newfoundland-proofing' requirements.

Contractors in St. John's use specialized fastening patterns, such as 'storm nailing' (5-6 nails per shingle instead of 3) and extra ice and water shield, to ensure roofs can withstand the 100-140 km/h wind gusts common in the region.

Permit fees for residential repairs and renovations in St. John's typically range from $150 to $500 CAD, often calculated at $9 per $1,000 of construction value for projects up to $100,000.

August is the peak of the short, frantic roofing season. Homeowners can often save 10-15% by booking for late summer or early fall (September/October) before the autumn gales begin, as contractors look to fill their final season slots.
