These are estimated ranges, not quotes. Compiled from public installed-cost data for California and adjusted for how Downey 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 – $950 | $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. | $550 – $700 | $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 – $39,000 | 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 – $63,000 | 40 to 60 years |
| Standing-seam metalThe long game. Costs double up front and outlives two shingle roofs. | $1,500 – $2,700 | $27,000 – $81,000 | 40 to 70 years |
What moves the price
- How much decking turns out to be soft once the covering is stripped
- Ventilation work, if the old roof was cooking itself from underneath
- 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
- Warranty tier, which is really a question about who honours it in fifteen years
Locally
They also drive ember risk, which is why vent screening and Class A assemblies matter more here than the colour of the covering.
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 Downey is built. No contractor is bound by them.
Questions about price
It is leaking right now. What do I do?
Contain the water, photograph everything, and get the request in marked as an emergency. A tarp is the right first job. The permanent repair is a separate conversation and a separate price.
How long does a re-roof take?
Two days is typical for asphalt. Add days for steep pitch, multiple layers to strip, tile work, or a roof with a lot of valleys and penetrations.
Why three quotes and not one?
Because one price tells you nothing. Three tells you where the middle is, and the outliers are informative in both directions — the very cheapest is usually leaving something out, and the most expensive should be able to say what you are getting for it.
