Roofing in Quebec
What Quebec roofing contractors work under
Quebec differs from the rest of Canada in three ways a roofing business notices at once: an RBQ licence, its own consumer rules for sales made at the customer’s home, and French-language business documents.
An RBQ licence, subclass 7.0
Anyone who carries out construction work for someone else for profit needs a licence from the Régie du bâtiment du Québec. A specialized contractor needs the subclass for its work; roofing falls under 7.0, “Contractor – Insulation, waterproofing, roofing and siding”, which covers shingles and tiles on sloped roofs.

Chapter I of the Construction Code, and municipal rules for houses
Chapter I (Building) of the Quebec Construction Code now incorporates the National Building Code of Canada 2020 with Quebec changes, in force since April 17, 2025, with a transition to October 17, 2027. For houses, duplexes, triplexes and small residential buildings, the rules are set by the municipality, which also issues permits, so standards can differ from city to city.

Sales made at the customer’s home
Under the Consumer Protection Act, a roofing sale concluded at the consumer’s home is itinerant commerce, even when the customer invited you. The business generally needs a permit from the Office de la protection du consommateur, the contract must be in writing, and the consumer has 10 days to cancel, which can stretch to a year in some situations.

French-language documents
Invoices, contracts, purchase orders and receipts given to Quebec customers must be in French, and since June 1, 2023 a new standard-form contract must first be given in French. In Roof Manager, the Language switch in the report viewer translates the measurement report into French, and the PDFs you download follow it.

Falls and CNESST registration
On Quebec construction sites the employer must install guardrails where workers face a fall of more than 3 m, or use other fall protection where that is not possible. An employer with at least one worker in Quebec must register with the CNESST within 60 days of the first worker’s first day.
