San Dimas prices
Pricing a low-slope roof
A flat roof does not shed water; it holds it back. That makes seams and edges the whole job, and the whole price.

These are estimated ranges, not quotes. Compiled from public installed-cost data for California and adjusted for how San Dimas 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 – $925 | $13,000 – $27,000 | 25 to 30 years |
| 3-tab asphalt shingleThe cheapest thing that still counts as a roof. Fewer and fewer crews will install it. | $525 – $725 | $10,500 – $21,000 | 15 to 20 years |
| Impact-rated asphalt shingleClass 4 rated. Often earns an insurance discount where hail is a factor. | $825 – $1,300 | $16,500 – $37,500 | 25 to 35 years |
What moves the price
- Whether the valleys, drip edge and step flashing are being replaced or reused
- How many old layers have to come off before the new one goes on
- 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
- 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.
Be careful with coatings sold as replacements. Coating a sound roof buys years; coating a failed one buys a fresh colour.
These are estimates, not quotes. They are compiled from national installed ranges adjusted for California costs and for how San Dimas is built. No contractor is bound by them.
Questions about price
How long should a roof last here?
Rated life and real life are different numbers. Here, ordinary rated life is a fair guide, provided the attic breathes. Ventilation and the quality of the installation move that more than the brand does.
Are the contractors licensed and insured?
Contractors have to give us their state licence number and proof of liability and workers compensation cover before they can receive requests. You should still ask to see current certificates yourself before work starts — a licence can lapse between checks.
What warranty should I expect?
Ask for both in writing: the material warranty from the manufacturer and the workmanship warranty from the contractor. The second one is the one that matters in year three, and it is only as good as the company behind it.
