What we engineer
Toronto rooftops range from century-home rafters to modern flat commercial roofs. Older houses often have undersized or notched rafters, so we check the existing framing against the array and snow loads and design reinforcement when it’s needed.
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 solar go on an older Toronto house?
Often, yes. We check the existing rafters and roof sheathing, and if they’re not adequate we design reinforcement so the install can go ahead.
How fast can you turn around a Toronto solar letter?
Residential letters typically take 1–2 business days once we have roof photos, framing details and the array layout.
