The Complete Guide to Getting a New Roof in North Idaho (2026)

Do You Need a New Roof or a Repair?

Replace when the roof is 20 years old or more, wear is spread across it, the deck is sagging, or leaks keep showing up in different places. Repair when the roof is under 15 years old and the damage is in one area.

Granules piling up in the gutters and daylight through the roof boards in the attic are other signs a roof is near the end. See signs your roof needs replacing and repair vs. replacement. When in doubt, get a free inspection.

Which Roofing Material Should You Choose?

Most North Idaho homes choose between architectural asphalt shingles and standing seam metal. Shingles cost less upfront; metal lasts two to three times longer and sheds snow.

Compare them in detail in asphalt vs. metal roofing and when to switch to a metal roof. For full pricing, see the North Idaho roof cost guide.

How Do You Hire the Right Roofing Contractor?

Hire a contractor registered with the state of Idaho, with insurance you've seen proof of, a local track record, and a detailed written contract. Watch for door-knockers after storms and anyone who wants full payment up front.

• Registration: Idaho law requires contractors to be registered. Look them up through the Idaho Division of Occupational and Professional Licenses
• Insurance: to register, Idaho requires proof of general liability insurance of at least $300,000 and of workers' compensation, or a statement of why it isn't required. Ask for the certificates
• A local track record, with references and a Better Business Bureau record you can check
• A written contract that spells out tear-off, underlayment, flashing, ventilation, the roofing itself, and how unexpected deck damage is priced

Do You Need a Permit for a New Roof?

Yes. Kootenai County and the cities of Coeur d'Alene, Post Falls, Hayden, and Rathdrum all issue re-roof permits, and Idaho law requires every building permit to show the contractor's registration number and to be posted at the job site.

Fees are modest: for example, Rathdrum lists $150 for a residential re-roof with tear-off, and Coeur d'Alene charges a $50 processing fee plus $100 to $250 depending on roof size. Coeur d'Alene also requires replacing any rotted wood and using roofing rated at least Class A or B. See roofing permits in Kootenai County for every city.

What Does the Building Code Require for a New Roof?

Idaho builds houses to the 2018 International Residential Code. For a new roof that means ice barrier at the eaves where ice dams are a known problem, drip edge at the eaves and gables, flashing at walls and openings, and no new layer over a roof that already has two.

• Ice barrier: Coeur d'Alene and Post Falls both require it
• Drip edge at eaves and gables of shingle roofs, with pieces overlapped at least 2 inches, as Hayden's roof handout shows
• Flashing at wall-to-roof joints, chimneys, skylights, and vents. See roof flashing explained
• Ventilation that meets code. See our roof ventilation guide
• Tear-off: a new layer can't go over a roof that already has two layers, or over one that is wet or deteriorated

How Do You Pay for a New Roof?

With insurance if a covered storm damaged the roof, otherwise with savings, a home equity loan or HELOC, a personal loan, or financing arranged through the contractor.

If a storm caused the damage, photograph it, report it to your insurer as soon as you decide to file, and keep receipts for any emergency repairs. Ask whether your policy pays replacement cost or actual cash value. See how to file a roof insurance claim in Idaho and roof financing options.

What Happens on Installation Day?

Tear-off and deck inspection first, then underlayment and ice barrier, flashing and drip edge, the shingles or metal, the ridge and vents, and cleanup. Most shingle roofs take 1 to 3 days.

1. Tear-off

   The old roofing comes off down to the deck, with tarps protecting landscaping.

2. Deck inspection

   Any rotted or damaged plywood or OSB is replaced. This is where unexpected costs can show up, so know how your contract prices it.

3. Underlayment and ice barrier

   Ice barrier at the eaves, valleys, and openings, and synthetic underlayment over the rest of the deck.

4. Flashing and drip edge

   Metal flashing at walls, chimneys, skylights, and pipes, and drip edge at the eaves and gables.

5. Shingles or metal

   Installed from the eaves up to the ridge.

6. Ridge and ventilation

   Ridge cap and the ridge vent or other exhaust vents.

7. Cleanup and walkthrough

   Debris hauled off, a magnetic sweep for nails, and a walkthrough with you.

Afterward, get copies of the manufacturer and workmanship warranties, confirm the permit inspection is finished, and keep the contract, invoice, and warranties together.

When Is the Best Time to Get a New Roof?

Late spring through early fall, May through September. Owens Corning's instructions say that below 40°F the shingles' adhesive strip may not activate, so we don't recommend planning a replacement for winter.

Schedules fill fast in fall, so plan a replacement 4 to 8 weeks ahead. See when to book a roofer and the best time to replace your roof.

How Do You Take Care of a New Roof?

Have it inspected once a year and after big storms, keep the gutters clean, trim branches back from the roof, keep the attic ventilated, and watch for ice dams in winter.
