Common questions about roofing in Hamilton, answered by our experts.
The average roof replacement in Hamilton costs $5,000-$15,000 for a typical home. Factors include roof size (measured in squares), pitch complexity, material choice, and whether structural repairs are needed. Asphalt shingles are most economical at $3.50-$5.50/sq ft installed. We provide free detailed estimates.
Architectural asphalt shingles are the best value for most Hamilton homes—they handle our freeze-thaw cycles well and last 25-30 years. For longevity, metal roofing (50+ years) excels in our climate with superior snow shedding. We recommend materials based on your home's architecture and budget.
Most residential roofs in Hamilton are completed in 1 day by our experienced crews. Larger homes or complex roof designs may take 2-3 days. Weather can affect timing—we won't install in rain. We'll provide a specific timeline during your free estimate.
Yes, the City of Hamilton requires building permits for roof replacements. We handle all permit applications as part of our service at no extra charge. Permits ensure your roof meets Ontario Building Code requirements and protects your home's value.
We provide a lifetime written workmanship warranty on all installations. Plus, as a GAF Master Elite contractor, we can offer GAF's Golden Pledge warranty—50-year material coverage plus 25-year workmanship backed by GAF. This warranty is transferable if you sell.
