Fontana runs about 18% above the California state baseline, so the state figures are scaled by 1.18 to give the local ranges below.
| Material | Per square installed | 20 squares | 25 squares | 30 squares |
|---|---|---|---|---|
| Architectural asphalt shingles | $602 – $861 | $12,036 – $17,228 | $15,045 – $21,535 | $18,054 – $25,842 |

Figures are per square — 100 square feet of finished roof — for installed work including tear-off, and are 2026 planning estimates rather than quoted prices. Squares shown allow for a typical 6/12 pitch and 10% waste. Always get three written quotes before committing.
| Roof size | Squares | Asphalt shingle range |
|---|---|---|
| 1,200 sq ft footprint | 15 | $9,027 – $12,921 |
| 1,500 sq ft footprint | 18 | $10,832 – $15,505 |
| 2,000 sq ft footprint | 25 | $15,045 – $21,535 |

| 3,000 sq ft footprint | 37 | $22,267 – $31,872 |
The California state permit average is around $450; large metros frequently sit above that and may add inspection or scaffolding requirements of their own.

Flat and low-slope roofs are priced differently from shingles: they use membranes (TPO, EPDM, modified bitumen) or spray foam with a protective coating, and are usually quoted per square foot of roof area. If your Fontana home has a flat roof, size it with the flat roof calculator and ask roofers to quote the membrane or foam system, its thickness and the coating warranty separately.
| Measure | Index |
|---|---|
| All items | 106.4 |
| Goods | 101.4 |
| Housing | 129.3 |
The U.S. Bureau of Economic Analysis puts prices for goods in the Riverside-San Bernardino-Ontario, CA metro area at 101.4 in 2024, 1% above the national level and 4% below California as a whole (106.1). Shingles, underlayment, flashing and fasteners track the goods index, so that is roughly how far the material half of a Fontana bid sits from the state figure. Housing costs (129.3) feed into what local crews have to earn, which is why labor, not material, explains most of the gap between a big metro and the rest of its state.

How Fontana compares with the rest of the country, for 14 materials: roof cost per square foot.
Getting quotes from crews that also work the next metro over? The same 25-square shingle roof is estimated at Los Angeles, CA (about $17,213 – $24,638 for 25 squares), San Diego, CA (about $16,830 – $24,090 for 25 squares), San Jose, CA (about $19,763 – $28,288 for 25 squares), Fresno, CA (about $14,663 – $20,987 for 25 squares), Portland, OR (about $14,100 – $20,400 for 25 squares). Each figure is that city's own multiplier on its state baseline.
A typical 25-square asphalt shingle roof in Fontana works out at roughly $15,045 – $21,535 installed. That is the California baseline scaled by the local factor of 1.18.
A one-storey 1,500 sq ft house has about 18 squares of roof at a 6/12 pitch with 10% waste, so roughly $10,832 – $15,505 for architectural shingles in Fontana. A two-storey house of the same floor area has about half the roof.
Title 24; wildfire zone. Metro labour rates, permit and inspection requirements, and disposal fees all differ from the state average, which is what the 1.18 multiplier represents.
Measure your roof in squares, then get three written, itemised quotes from licensed and insured local roofers on the same scope. Compare the per-square price and check each quote covers tear-off, decking, underlayment, flashing, ventilation, disposal and the permit.
In almost every jurisdiction yes, and a licensed contractor will pull it as part of the job. Budget roughly $275–$725 for the fee, but check with the Fontana building department, which sets it. Replacing a roof without one can cause problems at resale and can give an insurer grounds to dispute a later claim.
Three, from licensed and insured local contractors, each written against the same scope. Ask specifically whether flashing, drip edge, underlayment, ridge vent and decking replacement are included, because that is where quotes usually differ.
