Pricing a full re-roof in Commerce
The honest answer to "what does a new roof cost" is a range, and then a list of the things that move you within it.

These are estimated ranges, not quotes. Compiled from public installed-cost data for California and adjusted for how Commerce 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. | $625 – $950 | $12,000 – $26,500 | 25 to 30 years |
| 3-tab asphalt shingleThe cheapest thing that still counts as a roof. Fewer and fewer crews will install it. | $500 – $700 | $9,500 – $19,500 | 15 to 20 years |
| Impact-rated asphalt shingleClass 4 rated. Often earns an insurance discount where hail is a factor. | $825 – $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. | $1,200 – $2,100 | $23,000 – $59,000 | 40 to 60 years |
| Standing-seam metalThe long game. Costs double up front and outlives two shingle roofs. | $1,500 – $2,500 | $28,500 – $70,000 | 40 to 70 years |
What moves the price
- Ventilation work, if the old roof was cooking itself from underneath
- Whether the valleys, drip edge and step flashing are being replaced or reused
- Access — a truck that cannot get near the house adds hours to every load
- Pitch — anything over about 7:12 needs staging and slows a crew down
- The number of penetrations: chimneys, skylights, vents, solar mounts
Locally
They also drive ember risk, which is why vent screening and Class A assemblies matter more here than the colour of the covering.
Treat this as the shape of the market, not a price. The only real number comes from somebody who has been on your roof.

Questions about price
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.
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.
What happens to my information?
It goes to a maximum of three roofing contractors working in Commerce, and to nobody else. We do not sell it as a mailing list and we do not post it anywhere public. Our privacy policy sets out exactly what is shared.
