Why Some Homeowners Choose Metal
The Boise Foothills hold more than 210 miles of Ridge to Rivers trails, and homes near them sit in the city's wildland-urban interface. There, the fire code requires a Class A fire-rated covering, tested to ASTM E108 or UL 790, whenever a roof is replaced. Metal is one way to meet it. Ask to see the Class A listing for the exact panel and underlayment the roofer proposes.
Other owners simply want a different look, or a roof they plan to keep for a long time. Whatever the reason, get the details in writing and compare more than one bid.
Typical Reasons to Request Metal Roof Replacement
- Foothills fire rules. The Class A rule also applies when half or more of a roof is replaced within 12 months.
- A worn shingle roof. City code caps a roof at two layers and allows an overlay only over a single layer, so many metal jobs start with a full tear-off.
- A historic home. Going from shingles to metal in a Boise historic district is a change of material, which needs a Certificate of Appropriateness.
- Snow-load worries. Record snow caused widespread roof collapses across Ada and Canyon counties in winter 2016–17. Ask the roofer to check the deck and framing too.
How Metal Roof Replacement Is Priced
Idaho estimates put metal at roughly twice the per-square-foot cost of asphalt shingles, and standing-seam steel well above that. Panel profile, gauge, trim, roof pitch and tear-off all move the number. These 2026 figures are models, not quotes:
| 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) |
Our cost calculator uses $8.50 to $15.00 per sq ft of roof surface for metal. Because Boise bases the permit fee on the declared job value, a bigger metal contract carries a bigger permit fee too.
What to Expect
- Inspection. The roofer checks the decking, framing and attic, and notes any foothills or historic-district rules for your address.
- Panel choice and written bid. Profile, gauge, color, fasteners, underlayment and trim each appear on the estimate.
- Approvals. Boise requires a building permit for any re-roof. The roofer files for it at City Hall (Planning & Development Services, 150 N Capitol Blvd, 2nd Floor, (208) 608-7070) and lists an Idaho contractor registration number. In a historic district, the Certificate of Appropriateness comes first. Outside city limits, check with Ada County Development Services (208-287-7900).
- Tear-off and install. Old layers come off, deck repairs are made, then panels and trim go on.
- Wrap-up. Cleanup and any inspection the permit requires.
What You Can Expect
This site does no roofing work. Roofers pay a fee when we introduce them to you; you pay nothing.
- A state registration you checked. Idaho requires it for jobs over $2,000; verify it on the Division of Occupational and Professional Licenses lookup.
- Liability and workers' compensation papers, current and in the company's name.
- A local address and references from recent metal jobs.
Walk away from any offer to waive your insurance deductible; the Idaho Department of Insurance calls it a red flag. Signed the contract in your living room? Idaho gives you until midnight of the third business day to back out in writing.
Quick Answers
Does a metal roof need a permit in Boise?
Yes. Re-roofing an existing structure needs a City of Boise building permit, whatever the material. The roofer handles the application and supplies a state contractor registration number. If the home is in a historic district and the material is changing, a Certificate of Appropriateness is needed as well.
Can metal go over my existing shingles?
Only if there is a single layer now. Boise allows a maximum of two layers, and an overlay is limited to roofs with one. Even then, ask the roofer whether the decking is sound enough to leave covered, and get the answer in the written estimate.
Does the foothills rule mean I must choose metal?
No. The fire code asks for a Class A rating, tested to ASTM E108 or UL 790, not a particular material. Metal is one option. Ask each roofer which Class A products they propose for your foothills home and to show the rating in writing.
Will metal lower my insurance bill?
Idaho has no required insurance discount for any roof type and runs no state roof grant program. Some insurers may offer a credit for a Class A or impact-rated roof. Ask your own insurer before you sign, and get the answer in writing.
