In London, a permit is typically not required for a 'like-for-like' shingle replacement on sound sheathing. However, if you are making structural changes, replacing more than 25% of the decking, or switching materials (e.g., asphalt to metal), a permit is required, costing between $100 and $400.
For a typical 2,000 sq. ft. roof in London, homeowners can expect to pay between $12,000 and $22,000 for architectural shingles. Premium metal roofing for the same size can exceed $32,000.
Architectural asphalt shingles are the most popular choice, offering a balance of cost ($7–$10 per sq. ft. installed) and durability against London's freeze-thaw cycles and high humidity, with a lifespan of 25–30 years.
Most residential projects in London are completed in 1 to 3 days. A standard bungalow can often be finished in a single day, while complex multi-level homes in areas like Masonville or Byron may take up to 3 days.
