Sheet metal contractors handle the metal side of a roof and building envelope: flashing around chimneys, skylights and parapet walls, custom fascia and soffit, eavestroughs and downspouts, standing seam and metal shingle roofing, and the coping and cladding that keep water from getting behind a wall. Toronto's mix of flat-roofed brick buildings, older detached homes, and new low-rise infill means most jobs involve some amount of custom bending and fabrication rather than off-the-shelf parts. We currently track 147 sheet metal contractors serving the city, ranging from small flashing-and-eavestrough shops to larger outfits that fabricate standing seam panels on site.
What to look for before hiring
Flashing failures are one of the most common causes of roof leaks in Toronto's climate, where freeze-thaw cycles and heavy spring rain expose any gap in a metal seam. Look for a contractor who fabricates on site or has in-house brake equipment, since custom-bent flashing fits tighter than stock pieces. Ask what gauge and grade of metal they use (26-gauge galvanized or aluminum is common for residential flashing and eaves), whether they carry WSIB coverage and liability insurance, and whether the quote separates labour, material, and disposal. A contractor who can explain how they'll tie new flashing into your existing roof membrane or brick is usually more reliable than one who just quotes a price.
