Metal Roofing in Ontario
Metal roofing covers standing seam panels, steel shingles, corrugated sheet, and metal tile systems, installed on homes, cottages, barns, and commercial buildings across Ontario. We track 278 contractors in this category, ranging from small crews that specialize in residential standing seam to larger outfits that handle agricultural and industrial buildings.
What the work actually involves
A proper metal roof job starts with tearing off or overlaying the existing roof, checking the deck for rot, and installing an ice and water shield membrane along eaves and valleys, which matters more in Ontario than in most of the US given our freeze-thaw cycles and ice damming. Panels or shingles then go down with concealed or exposed fasteners depending on the system, followed by flashing, trim, and venting details. Fascia, soffit, and eavestrough work often gets bundled into the same quote.
What to check before you sign
Ask what gauge of steel is used (26-gauge is common for residential, thinner sheet flexes and dents more easily), whether the panels are Galvalume or painted steel with a Kynar or SMP finish, and what the paint warranty covers versus the workmanship warranty. Get written confirmation on fastener type, underlayment brand, and whether the crew is WSIB-covered and carries liability insurance. Ask for addresses of past metal roof jobs, not just references by phone.
Our scoring weighs review volume and recency, response patterns to negative feedback, licensing and insurance signals, and consistency across platforms, so you can shortlist contractors who show a real track record rather than just a handful of five-star reviews.

Common questions about metal roofing
- How much does a metal roof cost in Ontario?
- Steel roofing typically runs higher upfront than asphalt shingles, often in the range of $8 to $15+ per square foot installed depending on panel type, roof complexity, and whether a tear-off is needed. Standing seam with concealed fasteners costs more than exposed-fastener steel shingle systems. Get at least three itemized quotes since gauge, finish, and underlayment specs vary widely between bids.
- How long does a metal roof last compared to asphalt shingles?
- A well-installed steel roof commonly lasts 40 to 60 years, versus 15 to 25 years for asphalt shingles, which is why many Ontario homeowners treat it as a one-time replacement rather than a periodic expense. The paint finish and fastener quality affect how well it holds up to freeze-thaw cycles over that span.
- What should I expect during a metal roof installation?
- Expect a deck inspection first, then several days of work depending on roof size and complexity, including tear-off, ice and water shield installation along eaves and valleys, panel or shingle installation, and flashing around chimneys, vents, and skylights. Noise and debris are part of it, and a reputable crew will protect landscaping and do a magnetic sweep for stray nails afterward.
- How do I judge the quality of a metal roofing contractor?
- Look for a track record of completed metal roof jobs specifically, not just general roofing, since panel alignment and flashing details differ from asphalt work. Check for WSIB coverage, liability insurance, manufacturer certification if the panels carry a system warranty, and a workmanship warranty separate from the material warranty.
