Sheet metal work on a roof covers the parts that keep water from finding its way in where two surfaces meet: flashing around chimneys, skylights and walls, valley metal, drip edge, fascia and soffit cladding, and eavestrough and downspout systems. Some contractors in this category also fabricate and install standing seam metal roofing, cap flashing on parapet walls, and custom metal work for dormers and bay windows. It's a trade that leans heavily on precise measuring, bending and soldering rather than just laying material down, so the quality gap between a rushed job and a properly detailed one shows up fast the first time it rains hard.
Toronto's mix of older brick homes with chimneys and parapet walls, plus newer builds with complex rooflines, means flashing problems are one of the most common causes of leaks the directory sees referenced in job descriptions and reviews. When you're comparing the 77 sheet metal contractors listed here, look for a few things: whether they carry WSIB coverage and liability insurance, whether they use pre-finished, heavier-gauge steel or aluminum rather than thin stock that dents and oil-cans, whether they solder or seal joints properly instead of relying on caulking alone, and whether they'll give you a written scope that names the metal gauge, finish and warranty terms.
Our scoring weighs verified customer feedback, how consistently a contractor shows up in positive local mentions, responsiveness, and business longevity, so you're not just going on star counts alone.
