Best Metal Roofing Contractors in London

Metal roofing — standing seam and metal shingles — is valued in London for its longevity, wind resistance, and ability to shed snow and rain. The 5 contractors below were selected from our full London top 10 as the strongest for metal roofing work, ranked by experience, manufacturer certifications, BBB standing, and verified reputation.

London, Ontario's climate is defined by significant winter snowfall, dozens of freeze-thaw cycles through the shoulder seasons, and spring rainfall that tests any roof's drainage performance. This pattern accelerates granule loss on asphalt shingles installed in the city's extensive stock of post-war bungalows, cape cods, and century brick homes — making metal roofing an increasingly practical long-term option rather than a premium novelty. Standing-seam steel and aluminum systems, along with metal tile and R-panel profiles for secondary structures, are well-represented among London roofing contractors and are installed across every age of housing stock the city offers.

Ontario's absence of a provincial roofing trade licence means buyers evaluating metal in London depend on WSIB registration, liability insurance, and manufacturer certification as quality indicators. Metal roofing introduces specific technical requirements beyond shingle work: expansion joint management in longer panel runs, flashing integration at London's common brick-to-roof transitions, and proper substrate preparation when removing multiple shingle layers from decking that may show moisture damage from decades of freeze-thaw cycling. Selecting a contractor with documented metal experience rather than a general shingle roofer trying metal for the first time is the primary risk-mitigation step in this market.

How do I choose a metal roofing roofer in London?

Confirm licensing and insurance for Ontario, ask for metal roofing project references in London, get multiple written quotes, and check each contractor's BBB standing. Every company listed here has been independently researched.

Are London Ontario metal roofing contractors required to hold WSIB coverage?

Yes. In Ontario, WSIB coverage is mandatory for construction businesses, including sole operators performing roofing work. Ask any London metal roofing contractor for a current WSIB clearance certificate before work begins. Without it, if a worker is injured on your property, you as the homeowner can be exposed to liability under the Ontario Workplace Safety and Insurance Act.

What metal roofing profiles are most common in London's residential market?

Standing-seam steel is the most frequently specified system in London for full residential replacements, valued for its concealed fastener design and long warranty terms. Metal shake and tile profiles that replicate heritage aesthetics are also installed in London's older neighbourhoods where architectural character is a concern. R-panel and exposed-fastener systems are more common on garages, agricultural buildings, and accessory structures.

Does London's freeze-thaw climate affect metal panel performance?

Metal panels expand and contract with temperature change — a factor that must be accounted for in clip and fastener design to prevent panel distortion or fastener fatigue over time. Reputable London metal contractors use floating-clip concealed-fastener systems that accommodate thermal movement across the panel length. Ask specifically how the system manages expansion in a climate with London's temperature range before accepting a quote.
