💬What People Actually Paid
Community❓Common Questions
In Oshawa, a building permit is generally not required for the replacement of roof shingles or non-combustible siding of the same size. However, if you are making structural changes to the roof framing or adding a new roof structure, a permit is mandatory and fees are expected to increase by 3% in 2026.
For a typical 2,000 sq. ft. home in the Durham Region, homeowners should budget between $10,000 and $16,500 for a professional asphalt shingle replacement. This includes a full tear-off, disposal, and high-quality architectural shingles.
Metal roofing in Oshawa typically ranges from $5,000 to $23,000 depending on the material (steel vs. copper). While the upfront cost is roughly 2-3 times higher than asphalt shingles (which average $7/sq. ft.), metal roofs offer a lifespan of 40-70 years, significantly outlasting the 15-25 year lifespan of shingles.
Prices are projected to rise by 4-6% in 2026 due to a combination of skilled labor shortages in the GTA and a 5-8% increase in material costs from major manufacturers like GAF and CertainTeed, driven by higher production and transportation expenses.
