These are estimated ranges, not quotes. Compiled from public installed-cost data for California and adjusted for how Walnut 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 – $975 | $11,500 – $28,500 | 25 to 30 years |
| 3-tab asphalt shingleThe cheapest thing that still counts as a roof. Fewer and fewer crews will install it. | $525 – $700 | $9,500 – $20,500 | 15 to 20 years |
| Impact-rated asphalt shingleClass 4 rated. Often earns an insurance discount where hail is a factor. | $825 – $1,300 | $15,000 – $37,500 | 25 to 35 years |
| Concrete tileThe tile lasts far longer than the underlayment beneath it, which is the catch. | $1,200 – $2,100 | $21,500 – $61,000 | 40 to 60 years |
| Standing-seam metalThe long game. Costs double up front and outlives two shingle roofs. | $1,500 – $2,500 | $27,000 – $72,500 | 40 to 70 years |
What moves the price
- The number of penetrations: chimneys, skylights, vents, solar mounts
- How many old layers have to come off before the new one goes on
- Access — a truck that cannot get near the house adds hours to every load
- Whether the valleys, drip edge and step flashing are being replaced or reused
- Permit and inspection fees, which vary more between towns than people expect
Locally
Dry offshore wind lifts material that damp coastal air had been holding down. Most wind losses here happen on a handful of nights a year.
Treat this as the shape of the market, not a price. The only real number comes from somebody who has been on your roof.
These are estimates, not quotes. They are compiled from national installed ranges adjusted for California costs and for how Walnut is built. No contractor is bound by them.
Questions about price
Why does ventilation keep coming up?
It is the most under-sold part of a roof. Trapped heat and moisture shorten shingle life, warp decking, and in cold weather it is what turns snow into an ice dam.
Are gutters included in a re-roof?
Usually not, unless the quote says so. If they are near the end of their life, replacing them during the re-roof is meaningfully cheaper than doing it later, because the crew and the staging are already there.
Do you cover the whole Los Angeles County area?
Yes. The contractors we match on cover Walnut and the surrounding towns, so if you are just outside the city limits it still works.
