Irvine prices
Pricing a low-slope roof
Flat roofing is priced by the square like everything else, but the cost sits in the details — terminations, drains, and how the membrane meets every wall it touches.

These are estimated ranges, not quotes. Compiled from public installed-cost data for California and adjusted for how Irvine 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 – $29,500 | 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 – $21,500 | 15 to 20 years |
| Impact-rated asphalt shingleClass 4 rated. Often earns an insurance discount where hail is a factor. | $900 – $1,300 | $16,000 – $40,500 | 25 to 35 years |
What moves the price
- Whether the fasteners and flashing are specified for coastal exposure
- Warranty tier, which is really a question about who honours it in fifteen years
- Pitch — anything over about 7:12 needs staging and slows a crew down
- How much decking turns out to be soft once the covering is stripped
- How many old layers have to come off before the new one goes on
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.
Ask where the water goes and what happens when the drain blocks. On a flat roof that is not a detail, it is the design.

Questions about price
How quickly will someone call?
Usually within the hour during working hours. If you marked the job as an emergency it goes to the front of the queue and is normally picked up faster than that.
What if the decking is rotten underneath?
Expect a few sheets on most older roofs. Get the per-sheet rate in the contract. Open-ended decking charges are where a fixed price stops being fixed.
How long should a roof last here?
Rated life and real life are different numbers. Here, salt and sun together tend to take the low end of any rated life. Ventilation and the quality of the installation move that more than the brand does.
What is it going to cost?
No cost. We email you once when a provider near you can take it on.
