Sheet metal work is the part of a roof that fails quietly, until it doesn't. Flashing around chimneys, valleys, skylights and walls; fascia and soffit; eavestrough and downspouts; standing seam or custom metal roofing panels: this is the trade that keeps water from finding the one gap in an otherwise sound roof. In Mississauga's climate, freeze-thaw cycles and heavy spring rain put real stress on these joints, so the quality of the metal work often matters more than the shingles or membrane it protects.
We track 13 sheet metal contractors serving Mississauga, ranging from crews that focus on flashing and eavestrough repair to shops that fabricate custom metal roofing and cladding on site with a brake.
Our ranking weighs review volume and rating trends, how consistently a company responds to complaints, how long they've operated in the Mississauga area, and signals of real fabrication capability versus subcontracted patch work. The full ranked list is at best roofing contractors in Mississauga, and the scoring inputs are laid out in detail on our methodology page.

13 businesses, scored on recent reviews. The order weighs each business's overall score by how much of its reviewed work is sheet metal contractor, so a lower-scored specialist can rank above a higher-scored generalist.
Reviewers consistently report fast, professional roof work from Andrew's team, with most jobs finished in two or three days. Strong emphasis on punctuality, cleanup, material quality, and the crew's courtesy; one customer notes the team accommodated repeated insurance delays without complaint.
Andrew and his crew deliver emergency repairs within hours and replacements within days, backed by drone inspections and detailed explanations at every step. Reviewers consistently praise their honesty about what work is needed, the professionalism of team members like Enrique and Agustin, and meticulous cleanup after the job finishes. Service spans roof repairs, replacements, chimney work, and damage from storms. Andrew responds to calls on weekends and fits urgent requests into his schedule quickly. Customers describe feeling informed and stress-free throughout, with pricing described as fair and quotes explained clearly before work begins.
Angel Brothers installers and the sales team deliver consistently polished work, from eavestrough replacements to Gemstone lighting. Customers praise the walk-throughs, cleanup, and no-mess installations; one reviewer noted the crew upgraded their earlier Gemstone system at no charge when standards improved. LeafGuard has performed through major rainstorms on multi-year-old installations, winning over neighbours. Across thirteen Gemstone reviews and six eavestrough or LeafGuard reviews, professionalism and product performance stand out as reasons customers recommend widely. The business operates as the Official LeafGuard Dealer serving the GTA and beyond. Prices shown are "Labour Installation: 75% Off". Joseph R. and Scott handle consultations with detailed explanations; Angel Brothers and Genty lead installations. No complaints emerge in recent reviews; the only caveat concerns products and warranties, which the business explicitly advises customers to investigate.
Ivan and his team deliver professional gutter and downspout work with a hands-on approach. He visits sites to measure properly, explains solutions clearly, and completes jobs on time and clean. One reviewer noted an invoice presentation issue, but most praise his old-school work ethic, responsiveness to emergencies, and fair pricing relative to the quality delivered. The business serves Mississauga and surrounding areas (Etobicoke, Brampton, Oakville, Milton, Burlington, Halton Hills, Georgetown) and handles everything from cleaning and guards to full replacements and soffit work. Staff like Victor assist on larger jobs, and customers consistently highlight how Ivan catches problems others missed, then solves them without overcharging.
Martin's sales consultations stand out for clarity and honesty; crews like Khazin and Brian finish jobs fast, often same-day or within 2 days, with fastidious cleanup that neighbours and contractors alike notice. Staff know their trade deeply, catch issues beyond the initial scope, and respond within hours to emergencies. One reviewer mentioned room for final cleanup attention, but the pattern across 19 recent reviews is relentless professionalism and customer-focused follow-up. Damian (the owner) personally inspects finished jobs. Teams include specialists like Dean and Adam for eaves and metal work. Beyond roofing, the crew handles skylights, flat roof repairs, chimney removal, and siding with the same precision. They operate across the GTA and have GAF and VELUX certifications backing their materials and methods.

Most customers praise D'Angelo and Sons for fast, professional eavestrough and roof work with responsive sales teams and skilled crews like Carlos Jr. who communicate clearly and leave sites clean. Two reviews flag serious gaps: a $40,000 flat roof warranty went undocumented after installation, and one customer reported abandoned communication during a time of need, suggesting occasional service lapses on larger projects.
Homeowners consistently report fast response times, fair quotes that often undercut competitors, and reliable completion. Serg and named crew members (Andriy, Sergiy, Andrey) earn praise for catching problems others missed, protecting property during work, and leaving sites spotless-though one reviewer noted questionable debris handling. The business handles flat roof repairs, shingled installations, metal roofing, gutters, siding, and emergency snow removal across the GTA. First-time homeowners and those burned by other contractors highlight their honest assessments and stress-free communication. Wind and storm damage jobs receive same-day response.
Toronto Roof Repairs charges fair rates and shows up when promised, with Stan and the team diagnosing problems honestly rather than inventing work. Office staff Vanessa and Veronica coordinate quickly, and the company returns at no charge until leaks stop and customers are satisfied, earning trust across Greater Toronto Area work.
Alex and his team consistently earn five-star ratings for leak diagnosis, shingle replacement, and gutter work done with precision and care. They keep job sites clean, send photo updates throughout, and stick to timelines and pricing, earning trust across dozens of repeat referrals.
Brad and his team deliver reliable roof repairs and replacements across the GTA, with most customers praising fast response times, transparent pricing, and skilled workmanship. One recent review flags communication issues, though older reviews consistently highlight responsiveness and quality materials that hold up over years, backed by on-warranty service at no extra charge.
Overwhelmingly praised for professional, attentive work on condo and commercial properties across Ontario and BC. Staff send detailed photo reports and understand building mechanics well. Two low ratings cite unresolved roof leaks after multiple visits and a traffic complaint unrelated to work quality.
Two reviewers called out professionalism and knowledge, but with only three five-star reviews total, the picture remains limited. Their website lists over 30 years in business, 24/7 emergency coverage, and work across flat and metal roofing with waterproofing services.
Not enough recent reviews yet to synthesise a reliable sentiment read for this business.
