Your roof protects everything under it, so the roofer you hire matters as much as the shingles you choose. A great roofer installs a roof that lasts decades. The wrong one can leave you with leaks, voided warranties and a company that no longer answers its phone.
Use this checklist to narrow your options.
1. Local Address and Track Record
Look for a company with a real local address, a local phone number and years of work in your area. A contractor who has been around for a long time has a reputation to protect and will still be there if you need warranty service.
2. Liability Insurance and WSIB Coverage
Ask for a certificate of liability insurance and a WSIB clearance certificate, and check that they're current. Roofing is dangerous work. If an uninsured worker is hurt on your property, or your home is damaged, you don't want to be the one left with the problem.
3. Reviews and References
Read Google reviews over several years, not just the most recent ones. Look at how the company responds to complaints. Ask for references or photos of recent jobs near you, ideally on homes like yours.
4. A Detailed Written Quote
A good quote lists:
- Shingle or membrane brand and product
- Underlayment and ice and water protection
- Flashing and ventilation work
- Tear-off, disposal and cleanup
- Price per sheet for any extra plywood
- Start date, payment schedule and warranty
If a quote is one line long, ask for more detail. Our guide on how to compare roofing quotes walks through it.
5. Workmanship Warranty in Writing
Shingle manufacturers cover the product. Your roofer should cover the installation. Ask how long the workmanship warranty lasts, what it covers and how to make a claim. Get it in your contract. Learn more in shingle roof warranties explained.
6. Their Own Crews (or Known Subcontractors)
Ask who will actually be on your roof and who supervises the job. There's nothing wrong with trusted subcontractors, but you should know who is responsible for the work.
7. Clear Communication
Notice how the company treats you before you sign. Did they show up when promised? Did they explain the problem with photos? Did they answer your questions without pressure? That's usually how the project will go too.
8. Reasonable Payment Terms
A deposit for materials is normal. Paying in full before work starts, or paying cash with no paperwork, is not. See our guide to roofing scams in Ontario for the warning signs.
Questions to Ask Before You Hire
- How long have you been in business here?
- Can I see your insurance and WSIB certificates?
- Will you remove all old layers and inspect the deck?
- What happens if you find rotten plywood?
- How do you protect my landscaping and property?
- How long is your workmanship warranty?
- Who do I contact if something goes wrong later?

Frequently Asked Questions
Do roofers need a licence in Ontario?
Ontario doesn't have a provincial licence for roofing contractors, although some municipalities require business licences and building permits for certain work. That makes insurance, WSIB coverage, reviews and a written contract even more important.
Should I always choose a local roofer?
Local roofers know Ontario's building requirements and weather, and they're easier to reach for warranty service. That's a strong advantage over out-of-town crews.
How far in advance should I book a roofer?
Spring and fall fill up quickly. For non-urgent replacements, contact roofers a few weeks to a couple of months ahead.
