Most Boise homeowners pay between $8,000 and $18,000 to replace an asphalt shingle roof. A small, simple roof can land closer to $7,000. A large or steep roof, or one with rotted decking underneath, easily passes $20,000. Metal runs $15,000 to $40,000 and up.
Those are the numbers Boise roofers are actually quoting in 2026, not a national average from some calculator that doesn't know our snow and hail.
Cost by material
| Material | Cost per sq ft | Typical total | Lifespan |
|---|---|---|---|
| Asphalt shingles (3-tab) | $3.50–$5.50 | $7,000–$11,000 | 15–25 years |
| Architectural shingles | $4.75–$7.50 | $9,000–$16,000 | 25–35 years |
| Impact-resistant shingles | $6.50–$9.50 | $13,000–$20,000 | 25–40 years |
| Standing-seam metal | $8.50–$14.50 | $17,000–$40,000+ | 40–70 years |
These totals assume a typical 1,500 to 2,000 square foot roof. Bigger roof, bigger number. To sanity-check a quote, Boise roofers price by the "square" (100 square feet). Architectural shingles run about $450 to $700 a square installed.
What the price actually covers
A roof quote breaks into three parts: materials, labor, and everything the salesperson doesn't mention over the phone.
Materials are the shingles, underlayment, flashing, and ridge vents. Labor in Boise averages about $61 an hour, and most of the labor is in the tear-off, not the nailing.
Then there's everything else. Tearing off and hauling away the old roof. Rotted decking you can't see until the shingles come off. The Ada County permit, which runs about $157. Each one tacks a few hundred to a couple thousand onto the final bill.
Why Boise roofs cost what they do
We get snow, hail, and long dry stretches of summer heat. Roofs here are built for snow load, and a lot of homeowners step up to impact-rated shingles because of hail. The "just buy the cheapest shingles" advice you see on national sites doesn't always hold up in the Treasure Valley.
How to not overpay
Get three written quotes, not one. Ask each roofer the same thing: "What happens if you find rotted decking?" A roofer who can't answer that clearly hasn't done many Boise roofs.
Check the license. Every Idaho contractor has to be registered with the state, and you can look them up. Skip the one who "knows a guy."
Find a licensed Boise roofer
We keep a list of licensed, insured Boise roofers with reviews so you don't have to verify each one yourself.
