Idaho contractor registration, described generally
Idaho handles roofers differently from electricians and plumbers. Instead of a trade license, most construction contractors register with the state through the Idaho Division of Occupational and Professional Licenses, and registration generally requires proof of liability insurance and, where applicable, workers' compensation coverage. Some small or exempt work may fall outside the rules.
Because requirements change, our advice is simple: verify current rules with the state, then look up the specific company in the state's public lookup. Match the legal business name to the name on the bid. A registration under a different company name than the one on the truck is worth a question.
Nothing on this page is legal advice. Registration rules, exemptions and fees change. Check directly with the Idaho Division of Occupational and Professional Licenses before relying on any summary, including this one.
Insurance: ask for the certificate the right way
Roofing is one of the riskier trades. If an uninsured worker is hurt on your property or a crew damages your house, you do not want to be the one sorting it out. Ask for a certificate of insurance, and ask the contractor's insurance agent to send it to you directly. That way you know it is current and real.
- General liability covers damage the contractor causes to your property.
- Workers' compensation covers injured workers. Ask how the crew is covered, including any subcontractors.
- Dates and names. Check the policy dates cover your job and the named insured matches the company you are hiring.
Permits: check with your city
Each city in the valley runs its own building department. Boise, Meridian, Nampa, Eagle, Kuna, Star and Caldwell each set their own rules for which roofing work needs a permit, and addresses outside city limits may fall under county permitting. Reroofs commonly need one, while small repairs may not. We do not list specific requirements here because they change; check with your city before work starts.
A permit usually brings a city inspection, which is an independent set of eyes on details like the ice barrier and ventilation. A contractor who suggests skipping the permit to save time is asking you to carry that risk.
Reading a bid so you compare the same job
Bids for "a new roof" can describe very different work. Before comparing totals, make sure each one answers these points:
| Item | What to look for |
|---|---|
| Tear-off | How many layers come off, disposal, deck inspection |
| Decking | How damaged sheathing is found and priced |
| Underlayment and ice barrier | Product type, where ice barrier goes and how far up |
| Flashing | New or reused at walls, chimneys, valleys and vents |
| Ventilation | Intake and exhaust plan; see Boise attic ventilation |
| Products | Brand, line and color named, not "or equal" |
| Schedule and payment | Start window, deposit, progress payments, final payment after inspection |
| Coverage | Workmanship terms and manufacturer coverage, in writing |
If one bid is much lower, it often leaves something out. Lay the scopes side by side before deciding. The Boise roofing materials comparison helps you judge the product lines.
Red flags worth walking away from
- Pressure to sign the same day, or a "price good only today".
- Large cash deposits, or payment to a name different from the company.
- No physical business address, or a phone number that only takes texts.
- Offers to waive an insurance deductible.
- A refusal to put the scope, products or schedule in writing.
- Reluctance to give a registration number or insurance certificate.

Common questions
Does Idaho require roofers to be licensed?
Idaho generally requires construction contractors, including roofers, to register with the state through the Division of Occupational and Professional Licenses, and registration involves proof of insurance. It is not the same as the trade licensing used for electricians or plumbers. Rules change, so verify the current requirements and look up the contractor yourself.
Who is responsible for the permit?
Usually the contractor pulls the permit for a reroof, but ask and get it in writing. Your city building department can tell you whether your job needs one. A permit means the city may inspect the work, which protects you.
How many bids should I get?
Two or three written bids for the same scope is a common habit. More than that tends to add confusion rather than clarity. What matters is that every bid describes the same work so you can compare them.
