When planning for a residential roof repair or replacement project, many Canadian homeowners are unfamiliar with their local building codes and/or permit requirements.

While it’s often assumed that their roofing companies will take care of these details on their behalf, homeowners are often surprised to learn that they must source and submit any building permit requirements to their contractors before the project can begin.

However, not all roofing projects will require a building permit in Ontario.

Whether you live in Toronto, York Region or Barrie – the project specifics (such as materials, size, weight etc) must be in compliance with the Ontario Building Code, which include the following categories:

  • Zoning Regulations
  • Structural Standards
  • Electrical Codes
  • Fire Regulations
  • Health Regulations
  • & Energy Conservation Initiatives

At T. Simpson Roofing Ltd., we pride ourselves on over 25 years of industry-leading roofing solutions to best serve our local communities.

To help you prepare for your upcoming roofing project, the following article will explain why building permits are necessary, who is responsible for obtaining a building permit, and a closer look at which types of roofing projects may or may not require a permit in Ontario.

Why Are Building Permits Necessary in Ontario?

Essentially, the purpose of a building permit is to help protect you, your property and the best interests of your local community.

By ensuring that each renovation project follows the legal standard of the Ontario Building Code (as well as any other applicable zoning or municipal laws), homeowners can ensure the safety and integrity of their properties not only for their own families, but for any future occupants as well. 

While fees and restrictions may differ from one municipality to the next, we highly recommend checking in with your local Planning Office to determine specific requirements for your project.

Who is Responsible for Obtaining a Building Permit in Ontario?

In most cases, it is the responsibility of the property owner to apply for and obtain a building permit before their renovation project can begin.

However, that does not mean that your contractor cannot help direct you along the way!

As professional roofing contractors can offer a wealth of insight and support during the consultation phase of the project, here are a few topics to clarify in advance:

1. Will this project require a permit?
2. What is the effective time frame for a permit?
3. Who will apply for the permit? (eg. homeowner or contracting company)

In the case where your roofing company offers to apply for the permit on your behalf, you will

be required to submit a letter of authorization for them to do so, along with a note of this inclusion in your contractor’s work order.

However, it is important to note that it is the sole responsibility of the homeowner to obtain the correct permits along with all associated fees.

If you are unsure of which permits or documentation you may need, contact your local Planning Office for any applicable checklists, guidance and application tips.

When it comes to residential roofing projects, the scope of your project will play a large role in determining your local permit requirements.

As building permits are designed to ensure the safety and legality of home renovations, larger projects will require the use of a building permit while smaller, less-intensive projects may not.

These roofing services can be divided as follows:

Does Not Require a Permit:
Roof Replacement using the same type of roofing materials (eg. replacing shingles with shingles)
– Missing/Damaged Shingle Repairs
Eavestrough Installations
– Repairs that do not increase the weight of the original roofing materials
– Repainting Roofing Material

Requires a Permit:
– Adding Another Storey to the Home
– Removing Existing Roofing Structures
– Raising Part of Roof (for sunroom additions or larger rooms)
– Converting an Attic Space or Loft
– Installing a Skylight
– Changing the Slope or Pitch of the Roof
– Changing the Roofing Materials (eg. switching from metal to shingles)
– Adding a Walk-Out Addition Above a Garage

If the renovation project includes any alterations to the structural design of the building (such as electrical, mechanical, plumbing, fire separation etc), it may also impact your property’s compliance with local building regulations.

As every project is unique, we highly recommend speaking to a trusted roofing professional and/or your local Planning Office to identify the full scope of your next project.
