What roofing costs in Ontario
What roofs in this market actually go for, and the handful of things that decide where in the range yours lands. Use it to check a quote, not to replace one.
Or call (909) 738-1199Your request is in.
We are matching it now against roofing contractors working in Ontario and the surrounding area.
- Today, usually within the hour. The first contractor calls or texts the number you gave us. ASAP requests go out first.
- Up to three of them, no more. We cap it at three so you can compare without your phone melting.
- They come and look. Estimates are given after somebody has been on the roof, not over the phone.
- You decide, or you do not. There is nothing to cancel and nothing to pay us.
If you do not hear anything today, check your voicemail and spam folder — contractors often call from a mobile number.
These are estimated ranges, not quotes. Compiled from public installed-cost data for California and adjusted for how Ontario is built. No contractor is bound by them, and nobody can price a roof they have not stood on.
What a roof looks like as a monthly payment
Straight amortisation on the amount and rate you type in. Nobody is offering you these terms, us least of all — this is the arithmetic so you can check whatever a lender or a contractor does offer.
Prefilled with the middle of the typical Ontario replacement range. Change it to whatever you have been quoted.
Roofing paper commonly lands somewhere between about 7% and 18% depending on credit and on the programme. Put in the number you have actually been given.

The assumptions, in full
- A fixed rate, equal payments, and interest compounded monthly. Nothing is deferred and nothing balloons at the end.
- No down payment, no dealer or origination fee, no prepayment penalty, and no insurance product added on. Real roofing finance often carries a dealer fee, and it is usually already inside the price you were quoted.
- Promotional "same as cash" and zero-interest offers work differently: the interest is typically owed retroactively if the balance is not clear by the deadline. This table does not model that.
- The prefilled amount is the middle of the typical replacement range for Ontario from public cost data. It is not a quote for your roof.
Not an offer of credit. Summit Roof Pros of Ontario is a matching service — not a lender, not a broker, not a roofing contractor — and arranges no financing of any kind. We do not take an application, we cannot approve anybody, and no rate on this page is available from us. Terms come from whoever you actually borrow from.
What you should expect to pay in Ontario
Estimated installed ranges for a typical 23-square roof in Ontario — around 2,300 square feet of roof surface. These are guidance, not quotes.

| Covering | Per square | Typical whole roof | Expected life |
|---|---|---|---|
| Architectural asphalt shingleThe default choice on most American homes, and usually the right one. | $650 – $1,000 | $11,500 – $28,000 | 25 to 30 years |
| 3-tab asphalt shingleThe cheapest thing that still counts as a roof. Fewer and fewer crews will install it. | $550 – $750 | $9,900 – $21,000 | 15 to 20 years |
| Impact-rated asphalt shingleClass 4 rated. Often earns an insurance discount where hail is a factor. | $850 – $1,300 | $15,500 – $36,500 | 25 to 35 years |
| Concrete tileThe tile lasts far longer than the underlayment beneath it, which is the catch. | $1,300 – $2,100 | $23,500 – $59,000 | 40 to 60 years |
| Clay barrel tileOften salvaged and re-laid over new underlayment rather than replaced. | $1,700 – $3,400 | $30,500 – $95,000 | 50 to 80 years |
What moves the number
- Where you land in the season; crews discount when the phone is quiet
- Access — a truck that cannot get near the house adds hours to every load
- The number of penetrations: chimneys, skylights, vents, solar mounts
- How many old layers have to come off before the new one goes on
- Whether the valleys, drip edge and step flashing are being replaced or reused
Common repairs
| Emergency tarp-over | $425 – $1,200 |
|---|---|
| Small leak, flashing or a few shingles | $475 – $1,300 |
| Valley, chimney or skylight reflash | $950 – $3,100 |
| Section replacement, one slope | $1,500 – $5,100 |
What is behind these figures. National installed ranges, adjusted for California labour and material costs and for how Ontario is actually built. They are a sanity check on the quotes you receive, nothing more. No contractor is bound by them.
Extras that turn up on quotes
| Item | Typical range | Notes |
|---|---|---|
| Roof inspection | Free – $507 | Frequently free when it is tied to an estimate. Paid inspections buy you a written report you can hold somebody to. |
| Tear-off, per layer per square | $153 – $295 | Two old layers costs roughly twice what one does to remove and tip. |
| Seamless aluminium gutter, per foot | $12 – $27 | Most homes run 160 to 220 feet. |
| Ridge and intake ventilation upgrade | $633 – $2,577 | The cheapest thing you can do to make the next roof last its full life. |
| Tile lift-and-relay, per square | $722 – $1,346 | Existing tile comes off, new underlayment goes down, the same tile goes back. |
| Skylight replacement, each | $1,286 – $3,606 | Cheaper done during a re-roof than on its own afterwards. |
Cost questions
Are you a roofing company?
No, and it matters that we say so. We are a referral service, not a contractor. The roofing work, the licence, the insurance and the warranty all sit with the independent company you choose.
How long should a roof last here?
Rated life and real life are different numbers. Here, ordinary rated life is a fair guide, provided the attic breathes. Ventilation and the quality of the installation move that more than the brand does.
How many contractors will contact me?
Up to three. That is a hard cap, not a guideline. Three is enough to compare and few enough that your phone stays usable.
Should I take the cheapest quote?
Only if it is the same roof. Most large gaps between quotes are scope gaps. Ask the cheapest contractor which of the other quotes items they have left out, and why.
What if the decking is rotten underneath?
Expect a few sheets on most older roofs. Get the per-sheet rate in the contract. Open-ended decking charges are where a fixed price stops being fixed.
What is it going to cost?
No cost, no obligation, and never more than three contractors.
