What we engineer
Mississauga’s industrial parks have some of the largest flat roofs in the GTA, which makes them ideal for commercial solar. Older steel-joist roofs often have little spare capacity, so we analyze the existing joists and design reinforcement or ballast layouts that work.
Residential rooftop reviews
Structural letters confirming the roof can carry the array, sealed and ready for permit.
Commercial & industrial rooftops
Roof framing analysis and sealed drawings for large rooftop arrays.
Ground-mount systems
Foundation and racking design for ground-mount installations.
Roof reinforcement
Reinforcement details when existing framing needs upgrading for the array.
Racking & attachments
Review of racking layouts, attachment spacing and connections.
Snow & wind loads
Loads checked against provincial building code requirements for each site.

Common questions
Can a warehouse roof in Mississauga carry a large array?
Many can, but older steel-joist roofs often have limited spare capacity. We analyze the joists and design reinforcement if needed.
Do you work with commercial solar developers?
Yes. We work with installers, EPCs and developers on commercial rooftop arrays, with drawings typically in 5–10 business days.
