Sheet Metal Contractor in Ontario
Sheet metal work on a roof covers the parts that keep water out where the shingles or membrane can't: flashing around chimneys, valleys, and skylights, drip edge along the eaves, fascia and soffit cladding, and custom-bent metal for parapet caps, chimney chase covers, and eavestroughs. In Mississauga's climate, with heavy snow load in winter and freeze-thaw cycles through spring, poorly formed or corroded flashing is one of the most common causes of roof leaks, even on roofs where the shingles themselves are in good shape. A good sheet metal contractor brings a brake to bend metal on site to match exact roof angles, rather than relying on stock pieces that leave gaps.
We list 153 sheet metal contractors serving the Mississauga area, ranging from small operations that handle flashing repairs and eavestrough replacement to larger shops that fabricate custom metal roofing panels and commercial parapet systems. When comparing them, look at what gauge and grade of metal they typically work with (26-gauge steel and .032 aluminum are common baselines for residential flashing), whether they carry liability insurance for working at height, and whether they offer written workmanship warranties separate from the manufacturer's material warranty.

Common questions about sheet metal contractor
- How much does sheet metal roof flashing cost in Mississauga?
- Repairing or replacing flashing around a chimney, valley, or skylight typically runs a few hundred dollars per section, depending on metal type and roof access. Full eavestrough or fascia replacement on an average home usually lands in the low thousands, with custom-bent aluminum or copper costing more than standard steel.
- How often does roof flashing need to be replaced?
- Well-installed aluminum or steel flashing can last as long as the roof itself, often 20 to 30 years, but it should be inspected whenever shingles are replaced or after major storms. Rust spots, loose seams, or visible gaps are signs it needs attention sooner.
- What should I expect during a sheet metal repair visit?
- A contractor will inspect the problem area, check for water staining or soft decking underneath, and either patch and re-seal the existing metal or cut and bend new flashing on site to fit. Most straightforward repairs take a few hours, though custom fabrication work can take longer if pieces need to be shop-formed first.
- How can I judge the quality of a sheet metal contractor's work?
- Look for clean, tight seams with no visible caulk covering gaps, metal that's bent to fit the roofline rather than overlapped with sealant, and proper use of counterflashing at masonry joints. Ask whether they use a brake for on-site bending, since that usually produces a better fit than pre-formed stock pieces.
