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.
| 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 |
| Standing-seam metalThe long game. Costs double up front and outlives two shingle roofs. | $1,500 – $2,700 | $27,000 – $75,500 | 40 to 70 years |
What moves the price
- 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
- Permit and inspection fees, which vary more between towns than people expect
- Whether the valleys, drip edge and step flashing are being replaced or reused
Locally
These winds are not constant, which is the problem. A roof gets nine quiet months and then one night at fifty miles an hour, and whatever was marginal goes.
Use these as a sanity check rather than a quote. If every number you are shown sits well outside this range in either direction, that is worth asking about.
These are estimates, not quotes. They are compiled from national installed ranges adjusted for California costs and for how Ontario is built. No contractor is bound by them.
Questions about price
How much deposit is normal?
Ten to thirty per cent is ordinary, and is often used to order material. A demand for full payment up front is a reason to walk away.
I rent. Can I use this?
You can submit it, but the owner has to authorise any work, so the useful move is to get the landlord to make the request or to give you permission in writing first. Contractors will not start work for a tenant.
How long does a re-roof take?
A straightforward asphalt roof on an average house is one to three days. Tile, slate and complex rooflines take longer, and weather stops work more often than anything else.
What is it going to cost?
Free, no obligation, and your details go to no company until you say yes.
