Start with roof condition
Roof age alone is not the decision. Shingle condition, deck integrity, ventilation, flashing, penetrations, leak history and remaining service life should be reviewed before mounting equipment.
Roof + solar
Should You Replace the Roof Before Solar?
Coordinate the roof and array once to reduce avoidable removal, reinstallation and flashing risk.
Current planning assumptions
Preliminary installed pricing is $2.60-$2.73 per watt under pricing version solar-retail-2026-09-v1. These are planning figures, not a final contract price.
Roof-fit production is modeled first. A recommended preliminary system should then be sized against the home's actual annual electricity use. Micro-generation imports and exports depend on when the home uses electricity, when the panels produce it, and the customer's retailer plan; they are not estimated from a fixed public export percentage. Policy assumptions were last reviewed 2026-09-08.
Avoid paying twice
Installing over a roof near replacement can introduce panel removal and reinstallation cost, scheduling complexity and responsibility gaps. Coordinated sequencing gives the roofing and solar scopes a shared property record.
Calgary weather details
Hail exposure, wind, freeze-thaw cycles and attic ventilation deserve attention. Attachment and flashing details must protect the roof system while electrical and interconnection requirements are planned.
