Why a replacement goes through a permit
A replacement swaps out the roofing. The borough puts that job under permit, for a flat or low-slope roof as well as for a sloped roof. Changing the structure of a sloped roof needs one too.
A simple roof repair in Verdun needs no permit, according to the City.
The process, step by step
- Establish the type of roof. Below a slope of 2:12, the City speaks of a flat or low-slope roof. The two types follow different procedures. We confirm it during the visit.
- Get a detailed quote. It must give the cost of the work, taxes included. The City also accepts an estimate grid.
- Have the material approved. On a flat roof, the new covering must be green, white, with a reflective coating, with white ballast or with a solar reflectance index of at least 78. On a sloped roof, the new covering must have the same format, colour and texture as the original material, or as that of a comparable building on the same stretch of street. Ask for the data sheet of the proposed product.
- Gather the approvals. In a condo, you need a letter from each co-owner or a resolution of the syndicate.
- File the application and pay the fees. Online or at the counter.
- Set the work date once the permit is in hand.
What the permit costs
The City charges $9.80 per $1,000 of work. It collects at least $167.40 for a strictly residential building and $491.70 for a commercial, industrial, institutional or mixed-use building.
The estimate must include all costs tied to the work, taxes included, such as plans, labour and equipment.
Extra fees may apply if the building or its area has heritage value or is subject to special architectural standards. The fees are non-refundable.
Online or at the counter
The online service requires an account on montreal.ca. Payment is by credit card. If the replacement comes with other work, the City lets you file all renovation requests at once.
The Verdun permit counter is at 4555, rue de Verdun, office 104. Going to the counter is mandatory in one case, installing a green roof.
Who takes care of it
The City page allows an agent to act on the owner's behalf with a power of attorney. So we can file the application for you if you give us that power of attorney. Have the contract state who files the application and who pays the fees.
What the City does not specify
The two procedures consulted are silent on several points.
- the processing time for an application
- how long the permit stays valid
- any inspection during or after the work
- what happens if the work is done without a permit
For each of these, the answer is at the permit counter.
Frequently asked questions
Do you need a permit to redo a roof in Verdun?
Yes, replacing the covering of a flat, low-slope or sloped roof requires a permit from the borough of Verdun. Only maintenance and repairs are exempt.
Is a certificate of location needed for the application?
Verdun's procedures do not list the certificate of location among the required documents. They do call for "any other relevant document". Check with the counter before filing.
How long does it take to get the permit?
The City publishes no processing time on the pages consulted. File early and ask the counter for an estimate, especially if the work has to be done before winter.
