Emergency or can it wait?

If the roof is actively leaking, move belongings away from the water, catch the drips, and ask a roofer about temporary protection such as a tarp until repairs can be made — do not go on the roof yourself in bad weather. A few missing shingles or worn flashing can usually be scheduled, but should not be left too long. Each city page shows how many local roofers list 24-hour availability.

Questions to ask before you hire

Will you remove the old shingles, or install over them?
What underlayment and other materials are included?
Will this job need a permit, and who applies for it? Check the city page for local requirements.
What are the material warranty and the workmanship warranty, in writing?
Do you carry liability insurance and workplace injury coverage?
Is cleanup and disposal of old materials included?

How service areas work

Many roofers do not have a storefront and travel to customers across several cities. On BookHomeServices.ca, these service-area businesses appear on every city page they serve, so the same roofer can show up in more than one city. Businesses with a shop address are listed in their own city and may also serve nearby ones — check the city page for who covers your area.

Should I repair or replace my roof?

Repairs make sense for isolated damage such as a few missing shingles or a flashing leak. Replacement is worth considering when shingles are curling, cracking or losing granules across the roof, or when leaks keep coming back. Ask for a written assessment and quotes for both.

How often should a roof be inspected?

Many roofers suggest a check about once a year and after major storms. Look for missing or damaged shingles, loose flashing and granules in the gutters, and call a roofer if you see signs of a leak inside.
