A roof inspection in Ontario costs nothing, a flat fee, or is buried inside a home inspection, depending on who does it and why. One Ontario contractor’s 2026 guide puts a standalone roofing contractor inspection at $150 to $400, an insurance-focused inspection at $250 to $600, and a full home inspection, roof included, at $400 to $700. A roofer’s look that comes with a quote is usually free. What you actually pay for is the document at the end.
So the useful question is not the price. It is which document you need, and who asked for it.
Four things sold as a roof inspection
| What you book | Typical Ontario price | What you leave with | Who it suits |
|---|---|---|---|
| A roofer’s visit with a quote | Usually free | A price for roof replacement vs repair | You already plan to hire someone |
| A home inspection | $400 to $700 for the whole house | A few lines on the roof inside a full report | A buyer, as a first pass |
| A standalone roofing contractor inspection | $150 to $400 | Findings on shingles, flashing, attic ventilation and remaining life | An owner who wants an answer with no sale attached |
| An insurance or storm documentation inspection | $250 to $600 | Photographs and an opinion on cause | An insurer, an adjuster, a disputed claim |
Drone and thermal inspections sit alongside these, at $300 to $600 in the same guide, for steep or awkward roofs and suspected hidden moisture.
Toronto roofers publish higher numbers. One Toronto firm lists a pre-purchase inspection with a written report at $500 to $1,200. The pattern is the same in both guides: the more the document has to stand up in front of someone else, the more it costs.
What the free one is for
Nearly every roofer will come out and look at your roof for nothing. That is a fair offer, and there is nothing wrong with taking it. But understand the trade. The visit is how a contractor earns the chance to quote, so it tends to end with a number for the work and not much else.
That is fine when you are shopping for a repair. It is not fine when an insurer wants evidence of remaining life, or when you are deciding whether to firm up an offer on a house. For those, a price is not evidence. You need what was seen, where, with photographs, and a reason attached to any estimate of how long the roof has left.
What a home inspector is not required to do
A home inspection is good value, and a buyer should get one. It is still a general survey of the whole house, and the roof is one short section of it.
Under the InterNACHI Standards of Practice, which many home inspectors follow, the roof is inspected from ground level or the eaves. The same standard says the inspector is not required to:
- walk on any roof surface
- predict the service life expectancy
- remove snow, ice or debris that prevents a look at the roof
- confirm proper fastening or installation of the roof covering
- warrant or certify the roof
None of that is a criticism. It is the scope. But look at the list again if you are buying a house with a roof of unknown age: the two things you most want to know, how long it has left and whether it was installed properly, are both outside it.
The February problem in the snowbelt
This is the part the national cost guides leave out, and it matters here more than almost anywhere in the province.
At the north end of this service area, around Stratford, Listowel and the country behind Goderich, a roof can sit under snow for weeks at a time. A house listed in February may be sold, inspected and closed without anybody seeing a single shingle. The home inspector is not required to clear the snow, and nobody else is going to.
If you are buying in winter in the snowbelt, three things help:
- Ask the seller for the roof’s age and paperwork. An invoice or a permit record tells you more than a snow-covered slope.
- Look in the attic. The inspector can still check the underside of the deck, the insulation and the ventilation from the hatch, and staining or frost there is its own evidence. Snow that melts off one part of a roof faster than the rest is a sign of heat escaping from the attic, which is covered in why an ice dam roof problem is really a heat problem.
- Ask your agent what the condition period allows. A proper roof look may have to wait for a thaw, and it is better to know that before you firm up.
At the Erie shore end, around Chatham and Leamington, the snow clears faster and this is less of an issue. There the question after a bad summer is more often wind.
What moves the price of a standalone inspection
The same Ontario guide sets a simple bungalow at $150 to $250 and a two-storey with dormers and several valleys at $300 to $450. The spread follows the work:
- Height and pitch. A steep two-storey roof takes longer and needs more care to get onto safely, or a drone.
- Interruptions. Every dormer, valley, chimney and skylight is a junction to check, and junctions are where roofs fail.
- The attic. A good inspection looks at the roof from both sides. A tight hatch or a finished attic slows that down.
- The write-up. Photographs sorted by area and an opinion someone else will rely on take time at a desk, not only on a ladder.
Which report for which reason
The insurer is asking about age. Ask the insurer exactly what they want before booking anything. Some want a date, some want a remaining-life opinion, and some want photographs. A roof inspection report written for an insurer should state the age, the material, what was observed and a reasoned remaining life.
You are buying or selling. The home inspection is the first pass. If it flags the roof, or the roof is old enough that its remaining life is the real question, a standalone roofing inspection answers what the general survey was not required to. What decides that remaining life is covered in how long does a roof last in this climate.
A storm went through. Here the document has one job: to say whether the damage is consistent with that storm or with years of ordinary weather. What an adjuster needs to see is laid out in the guide to a roof storm damage insurance claim.
You already know the roof is finished. Then do not pay for an inspection. Get two or three replacement quotes, each of which includes a look at the roof for free, and compare what is in them using the guide to roof replacement cost in this corridor.
What to ask before you pay anyone
- Will you go on the roof, use a drone, or look from the ground?
- Will you check the attic?
- Do I get photographs, and are they sorted by where on the roof they were taken?
- Will you give a remaining-life estimate, and the reason for it?
- Is the price fixed before you come out?
An inspector who answers all five clearly is selling you information. One who will only tell you once they are on site is selling you a visit.
