Toronto roofing permits

Do you need a permit to replace a roof in Toronto?

Check whether a Toronto roof replacement needs a building permit, including the no-structural-work exemption and when the scope becomes permit work.

The short answerConditional

Usually not for a straight roofing-material replacement with no structural work. Structural roof changes can change the answer.

Toronto specifically lists replacing existing roofing material as permit-exempt when no structural work is required. Altering roof framing, changing the building structure or combining the job with other permit-required work is different.

Fees and timing

TimelineConfirm the scope before tear-off. If framing or structural work is discovered, stop and verify whether a permit is required before proceeding.
FeesNo building-permit fee applies to qualifying material-only replacement. Permit fees can apply if the scope includes structural work.

Next steps

  1. Confirm the job is material replacement only
  2. Inspect for planned structural changes
  3. Separate skylight or framing work from the roofing scope
  4. Verify permit needs before structural repair

A few questions you might have.

Do I need a permit to reshingle my Toronto house?

Toronto lists replacement of existing roofing material as permit-exempt when no structural work is required.

What if rotten roof framing needs replacement?

That can move the project beyond simple material replacement. Structural work should be reviewed before it proceeds.

Costs & budgeting

What will your Toronto building permit cost?

The fee depends on the work category. In Toronto’s 2026 schedule, a residential deck permit is $214.79; selected area- and length-based categories use a rate and minimum. Use the calculator for one category, then build the rest of your project budget separately.
