Metal roofing prices in Ontario, CA
Metal costs roughly double asphalt and lasts roughly three times as long. Whether that is a good trade depends entirely on how long you intend to stay.

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 |
| 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
- The number of penetrations: chimneys, skylights, vents, solar mounts
- Whether the valleys, drip edge and step flashing are being replaced or reused
- Warranty tier, which is really a question about who honours it in fifteen years
- How many old layers have to come off before the new one goes on
- Where you land in the season; crews discount when the phone is quiet
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.
Ask any contractor quoting metal to show you a standing-seam job they finished several years ago. The edges will tell you what you need to know.

Questions about price
What if the decking is rotten underneath?
Some of it usually is. The important thing is that the price per sheet is agreed in writing before the tear-off, so the conversation on day two is about quantity rather than rate.
Can I just put a new roof over the old one?
Codes in most places allow two layers. That does not make it wise. You lose the chance to see the deck, and the next roofer has twice as much to remove.
Do I have to hire anyone?
Not at all. Plenty of people use this to find out what a job costs and then do nothing for a year. That is a perfectly reasonable outcome.
What is it going to cost?
Free, no obligation, and your details go to no company until you say yes.
