Roof Replacement in Anjou

Step 1. Know which roof you have

The City handles flat and sloped roofs in two separate procedures. The dividing line is a slope of 2:12, or 16.7%. Below it, the roof is flat or low-slope. From 2:12 up, the roof is sloped.

For Anjou, both procedures say no permit is required to replace the roof. Only the flat roof procedure adds a list of materials. We measure the slope during the visit.

Step 2. Choose a compliant covering

If the roof is flat, the City asks for one of these coverings in Anjou.

• a material that is white, painted white, or covered with a reflective coating or white gravel
• a material with a solar reflectance index (SRI) of at least 78, confirmed by the manufacturer's specifications
• a green roof, meaning a vegetated roof

If the roof is sloped, the City publishes no list of materials for Anjou.

Step 3. Check with the counter for anything beyond the covering

A full replacement strips the roof bare. That is often when owners decide to replace some deck boards, add insulation or correct a slope. The City procedures for Anjou do not say whether work on the insulation or structure is permit-free. Ask the counter before signing.

For Anjou, the City's online service groups renovation permit applications that involve:

• the building interior
• doors and windows
• exterior cladding
• projecting elements such as stairs, balconies and decks

If your job includes a rooftop deck, a balcony to redo or cladding to replace along with the roof, check whether that work needs a permit. The page consulted does not say which ones do or under what conditions.

The Anjou permit counter receives in person, by appointment only, at 7171, rue Bombardier, 2nd floor.

Step 4. Compare quotes that can be compared

Ask us, as you would any contractor, for a written quote describing the same work.

• the tear-off of the old covering and what is planned if the deck is damaged
• the system installed, with the finishing product named
• the Régie du bâtiment du Québec licence number, which every construction contractor must hold
• the warranties

Our quote can be requested on this site for a roof located in Anjou.

Step 5. Keep the file

No permit will be issued, and no official document will describe your new roof. Keep the signed quote, the covering's data sheet, the invoice and photos of the job, which you can ask us for. Also ask your insurer what it would like to receive.

During the work, stay on the ground.
