Flat roof replacement does not require a building permit. However, if the replacement of other components becomes necessary during the construction of a flat roof, a permit will be required for these interventions, for example: roof drains, flashing, gutters, roof top terraces, or any materials located under the roof membrane such as the structure of a roof.

Generally speaking, if your project affects the exterior of the property, it is subject to the Site Planning and Architectural Integration Program (SPAIP) by-law and must be approved by City Council. However, restoration work on the original architectural components and identical replacement work are excluded. Article 3.1.3 of SPAIP By-law 1305.

Process of an application subject to the SPAIP by-law

Required documents for review:

  • A letter describing the scope of the proposed work;
  • A letter from the building owner authorizing the permit application, if the request is made by a third party;
  • A letter from the association of co-owners authorizing the proposed modification(s);
  • Clear and colour photos of samples or specifications of proposed materials;
  • Clear and colour photos of the site, all facades of the building, showing the existing roof;
  • An official cost estimate, excluding taxes, provided by a general contractor could be required.

The following documents may also be required:

  • A construction site management document (starting and end dates, phases, occupation of the public domain, etc.) as described in article 69 of Bylaw #1300;
  • A declaration form from the Régie du Bâtiment de Québec for any apartment building, public building and commercial building;
  • An inspection report from a licensed professional identifying the presence or absence of asbestos in compliance with the regulation respecting occupational health and safety (S-2.1, r.13), (required depending on the age of the building and the proposed work);
  • A deposit for potential damage to public property;
  • If scaffolding is to be located on City property a certificate for occupation of the public domain must be obtained from the City Public Works department.

This list is a summary. Please note that additional documents or information may be required in order to provide a better understanding of the project and contribute to the request process. (By-Law #1300, article 65, point 14o)

Once you have gathered all the information you can open your file at the Urban Planning Counter in City Hall or open an online application. 

  • The fee for the document analysis is 55$; the cost of the permit is separate.
  • The cost of the permit is calculated from the cost of work.
  • Important:
    • Repair files will be analyzed by the Urban Planning Department only.
    • All other files will then be referred to the Planning Advisory Committee and City Council.
  • The applicant will receive a follow-up via email.

Even if the permit has been authorized, it is not automatically issued. The permit must be paid for and certain documents must be submitted.

Information you need to bring:

  • A detailed construction cost, excluding taxes as provided by the general contractor or a project manager (tariffs By-law).
  • All other documentation requested that needs to be deposited prior to the issuance of a permit (ex. RBQ form, a site management document, asbestos report, sidewalk deposit, …).
