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.

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)
