Boise runs about 5% below the Idaho state baseline, so the state figures are scaled by 0.95 to give the local ranges below.
| Material | Per square installed | 20 squares | 25 squares | 30 squares |
|---|---|---|---|---|
| Architectural asphalt shingles | $399 – $570 | $7,980 – $11,400 | $9,975 – $14,250 | $11,970 – $17,100 |
| Standing-seam metal | $798 – $1,235 | $15,960 – $24,700 | $19,950 – $30,875 | $23,940 – $37,050 |

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 | $5,985 – $8,550 |
| 1,500 sq ft footprint | 18 | $7,182 – $10,260 |
| 2,000 sq ft footprint | 25 | $9,975 – $14,250 |
| 2,500 sq ft footprint | 31 | $12,369 – $17,670 |
| 3,000 sq ft footprint | 37 | $14,763 – $21,090 |
The Idaho state permit average is around $200; 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 Boise 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.

Getting quotes from crews that also work the next metro over? The same 25-square shingle roof is estimated at Seattle, WA (about $16,250 – $23,400 for 25 squares), Portland, OR (about $14,100 – $20,400 for 25 squares), Las Vegas, NV (about $11,550 – $16,538 for 25 squares). Each figure is that city's own multiplier on its state baseline.
A typical 25-square asphalt shingle roof in Boise works out at roughly $9,975 – $14,250 installed. That is the Idaho baseline scaled by the local factor of 0.95.
A one-storey 1,500 sq ft house has about 18 squares of roof at a 6/12 pitch with 10% waste, so roughly $7,182 – $10,260 for architectural shingles in Boise. A two-storey house of the same floor area has about half the roof.
Snow load; ice damming. Metro labour rates, permit and inspection requirements, and disposal fees all differ from the state average, which is what the 0.95 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 $125–$325 for the fee, but check with the Boise 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.
