Before signing, check the roofer’s RBQ licence and liability insurance, then get in writing the number of layers removed, the membrane and insulation proposed, the work on flashing and drains, the warranty, the permit and the payment schedule. Compare at least two or three quotes covering exactly the same work.
The 10 questions
- What is your RBQ licence number? Check it in the Régie du bâtiment du Québec register.
- Do you have liability insurance? Ask for current proof.
- How many layers will you remove?
- Which membrane and brand? See elastomeric vs TPO vs EPDM.
- Are you adding insulation? Type, thickness and cost.
- How will you handle flashing and drains? See flashing.
- What if the deck is rotten? Written unit price.
- Who handles the permit and colour requirements? See white roofs.
- What warranty, on what? Membrane and labour, in writing.
- What payment schedule? Never pay in full before the work is done.
Red flags
- No RBQ licence or refusal to provide it
