Attic to roof: free detailed quote, grants handled for you, certified crews.
In Granby, between old housing stock and new neighbourhoods, replacing the roof and insulating the attic to R-50 sharply cut heat loss.
Around downtown and Lake Boivin, Granby lines up workers' homes, post-war cottages and recent suburbs. The Townships microclimate (thaws, freezing rain, deep cold) puts roofs and attics through the wringer.
As a specialized insulation and roofing contractor, we serve Granby and the whole region (Estrie): under-insulated attic, vermiculite to remove, roof at end of life. We take it all on, attic to roof, with a free detailed quote and your grants handled start to finish.
From the attic to the roof, one specialist to protect and improve your property.
Our core trade: blown cellulose and fiberglass to R-50, air-leak sealing and corrected ventilation for a healthy attic.

Hydro-Québec's LogisVert program is the most popular insulation grant: up to $1,500 for owners of a house heated mainly with electricity, when the work combines roof insulation and air sealing, with no energy assessment required beforehand. At Toiture & Isolation Provinciale we don't just tell you about it: we fill out and submit the application on your behalf, from eligibility check to confirmation. You receive your reference number by email, zero paperwork on your end.
The Quebec government's Rénoclimat program pays up to $1,500 for the roof only if the insulation in place is R-12 or less ($750 or $250 above that). It requires an energy assessment before and after the work, by a recognized advisor. Our detailed reports are compliant and documented, and we support you at every step until approval.
Amounts, conditions, which one to pick: see our insulation grants guide.
Flexible financing with 3 months with no payments and no interest, so you can start your project right away. The grant arrives after the work. Subject to credit approval.
