These are estimated ranges, not quotes. Compiled from public installed-cost data for California and adjusted for how Diamond Bar 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 – $1,000 | $12,500 – $29,000 | 25 to 30 years |
| 3-tab asphalt shingleThe cheapest thing that still counts as a roof. Fewer and fewer crews will install it. | $500 – $725 | $10,000 – $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 | $17,000 – $37,500 | 25 to 35 years |
| Concrete tileThe tile lasts far longer than the underlayment beneath it, which is the catch. | $1,200 – $2,000 | $24,000 – $58,000 | 40 to 60 years |
| Standing-seam metalThe long game. Costs double up front and outlives two shingle roofs. | $1,600 – $2,600 | $32,000 – $75,500 | 40 to 70 years |
What moves the price
- How much decking turns out to be soft once the covering is stripped
- Warranty tier, which is really a question about who honours it in fifteen years
- 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
- 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.
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 Diamond Bar is built. No contractor is bound by them.
Questions about price
Can I just put a new roof over the old one?
Often you legally can, and it is usually a poor idea. Overlaying hides the condition of the decking, adds weight, shortens the life of the new shingles by trapping heat, and doubles the cost of the next tear-off.
Should I repair or replace?
Rough rule: if the covering has more than about five years left and the damage is confined to one area, repair. If it is at the end of its life or you are patching the third leak in two years, you are paying instalments on a replacement.
Are you a roofing company?
No, and it matters that we say so. We are a referral service, not a contractor. The roofing work, the licence, the insurance and the warranty all sit with the independent company you choose.
Ready for a real number?
No cost. We email you once when a provider near you can take it on.
