Same great service as we got 20 years ago. Adam was helpful with the quote and his men were very good. We would be glad to recommend Kerr's Roofing.

As a first time home owner, and single female I called Kerrs roofing with questions when I had issues with my roof. They were so helpful and professional, didn't try to oversell me and my roof is beautiful. They were all so kind and professional. I would recommend them to anyone.

Excellent service from Kerr Roofing! They were able to reshingle our new home in the week before we moved into it, which was very convenient for us. The crew were friendly. The clean up was thorough. The roof looks handsome, and the guarantee, from this longstanding company, is very reassuring.

We have only good things to say about our experience with Kerr Roofing. Adam arrived promptly and provided a competitive estimate. The whole crew arrived when promised, were polite and worked quickly and efficiently to complete the job on time and on budget! We have no hesitation in recommending their work.

Before you hire a roofer in Ontario

No. Roofing is not a compulsory trade in Ontario, so there is no licence to verify - which makes insurance and WSIB coverage the checks that matter.

WSIB clearance certificate

The most important document in this trade. Ask for a current certificate and confirm it names the company doing your work, not a subcontractor you have never met. It should be dated within the last 90 days.

Verify with: WSIB clearance certificates can be validated online by the account number.

General liability insurance

Two million dollars minimum for residential roofing. Request the certificate of insurance directly from the broker rather than a photocopy, and confirm the policy is current.

Manufacturer shingle certification

Optional but meaningful. Manufacturers certify installers, and certification is what unlocks the extended system warranty. Without it you have a material warranty only, which covers far less than most homeowners assume.

Municipal business licence

Some Ontario municipalities require one. Not universal, but easy to ask about.

Questions worth asking

Can I see a current WSIB clearance certificate and your liability certificate of insurance?
Is this a full tear-off, or shingling over the existing layer? (Overlays are cheaper and shorten roof life.)
How much ice and water shield is included, and how far up from the eave?
Are you certified by the shingle manufacturer, and does this quote include the system warranty or only the material warranty?
What happens if you find rotten decking? What is the per-sheet price, and will you show me before replacing it?
