Material-by-Material Prices
The figures below are statewide estimates from cost models and estimator sites, not quotes from Boise roofers. Each is labeled with its source and year. Per-square-foot prices are for the roof surface, which is larger than the floor area of your home once slope and overhangs are counted.
| Cost row | Figure | Source (year) |
|---|---|---|
| Idaho re-roof, typical total | about $7,947 (common range $6,117–$20,703) | This Old House, 2026 (a cost model) |
| Idaho asphalt shingles, per sq ft | about $4.17 per sq ft | This Old House, 2026 |
| Idaho architectural shingles, per sq ft | about $5.55 per sq ft | Roof Observations, 2026 (an estimate) |
| Idaho metal, per sq ft | about $8.11 per sq ft | This Old House, 2026 |
| Idaho standing-seam steel, per sq ft | about $14.35 per sq ft | Roof Observations, 2026 (an estimate) |
The wide spread in the first row is normal. A small, low ranch roof and a large two-story home with a steep pitch can sit at opposite ends of it. Metal costs roughly twice as much per square foot as basic shingles, and standing-seam steel sits well above that.
For a range sized to your home, try the roof cost calculator. It uses these same rows.
Pitch, Layers and Size
Two Boise homes with the same floor plan can get very different bids. The roof itself sets most of the price, and a few city rules can add steps. Boise homeowners have a lot riding on the answer, too: the Census puts the median value of an owner-occupied home in the city at $484,800, and 63.2% of homes are lived in by their owners.
- Roof area. Bids are priced on the roof surface, measured in squares or square feet. More area means more material, labor and disposal.
- How steep it is. A roof you can walk on goes faster. A steep pitch needs harnesses, staging and slower work, which adds labor.
- Layers already up there. Boise's city code allows no more than two layers of roofing, and an overlay is only allowed over a single layer. A roof that already has two layers has to be torn off first.
- The material you pick. Asphalt shingles cost the least per square foot. Metal panels and standing-seam steel cost more but are a different product with a different look.
- Foothills fire rule. In Boise's wildland-urban interface, a replacement roof must carry a Class A fire rating (ASTM E108 / UL 790). That limits which products a bid can include.
- Historic districts. In the North End or on Harrison Boulevard, changing the roofing material needs a Certificate of Appropriateness from the city before work starts. Same-material swaps need only the building permit.
- The city permit. A Boise re-roof needs a building permit. Its fee follows the declared job value on the City's building fee schedule, in effect since October 2023.
What a Written Estimate Includes
A fair comparison needs bids that list the same things. Ask each roofer for a written, itemized estimate, and check that it covers the points below before you sign anything.
- The roofer's Idaho registration number. State law has registered contractors print it on contracts. Search that number in the state's Division of Occupational and Professional Licenses lookup before you sign.
- Tear-off or overlay. The bid should say which one, and how many layers come off.
- Product and fire class. Brand, line, color and rating, so you can confirm Class A where the foothills rule applies.
- Who pulls the permit. Your roofer should file it with Boise Planning & Development Services and list its cost.
- Line items. Materials, labor, any decking repair, flashing, vents and haul-away, each shown on its own line.
- Proof of coverage. Liability insurance and workers' compensation, on paper.
- Your cancel window. A deal signed at your kitchen table can be canceled in writing through midnight of the third business day.
Insurance and Your Roof Cost
If wind or another storm damaged the roof, your homeowners policy may cover part of the cost. Your insurer decides what is covered. A roofer can inspect, photograph and price the damage, but the claim is settled between you and your insurer. If you want someone to negotiate for you, Idaho requires that person to be a public adjuster you hire separately.
Watch for any roofer who offers to waive or cover your deductible. Idaho's Department of Insurance lists that offer as a red flag of fraud. There is also no state roof grant open in Idaho, and no state rule requires insurers to discount premiums for a new roof. Ask your own insurer how a replacement would affect your policy.
