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.
