Most Idaho Falls homeowners spend $10,000 to $25,000 to replace an asphalt shingle roof, and $30,000 or more for standing seam metal. Roofs are priced by the square, which is 100 square feet of roof surface, so the calculator starts with your roof size and adjusts for material and pitch, the same way a roofer builds a quote. For the full breakdown, read our 2026 Idaho Falls roof cost guide.
Roof size. The biggest factor. A 2,400 sq ft roof is 24 squares, and every square needs material and labor.
Material. Architectural shingles are the most common choice here. Designer shingles cost more, and Class 4 impact-rated shingles cost more again but hold up better to hail. Standing seam metal costs the most up front, sheds snow well and can last 40 to 50 years.
Pitch and complexity. Steep roofs and roofs with many valleys, hips and dormers take longer and need more safety gear, so they cost more per square.
Tear-off and decking. The 2018 International Residential Code used in Idaho Falls doesn’t allow a new layer over two or more existing layers, so many older homes need a full tear-off. Rotted decking only shows up once the old roof is off, which is why an inspection gives a firmer number than any calculator.
Eastern Idaho extras. Ice and water shield along the eaves and valleys, snow guards on metal roofs, and the city building permit (re-roofing isn’t on Idaho Falls’ permit-exempt list) all add to the total.
As a rough planning guide: architectural asphalt runs about $450–$650 per square installed with tear-off, designer asphalt $600–$850, and standing seam metal $1,000–$1,600. Steep and complex roofs land at the top of each range. Your inspection confirms the exact rate.
Late spring through early fall. Shingles need warmth to seal and get brittle in the cold, so winter jobs take extra care and can be delayed by snow. Booking an inspection in late winter or early spring gets you on the schedule before the busy season.
If your roof is under about 15 years old and the damage is limited, a repair is usually the smarter spend. If it’s near the end of its life or leaking in several places, replacement is often cheaper over time.

It gives a realistic planning range based on Idaho Falls-area pricing and your roof’s size, material and pitch. It can’t see your decking, existing layers or flashing, so use it as a budget guide. A free inspection gives you the exact price.
Yes. The per-square rates include removing one layer of existing roofing and standard disposal. Extra layers or damaged decking add to the final quote.
A typical single-story Idaho Falls home with architectural asphalt shingles usually lands between $12,000 and $18,000. Larger, steeper or metal roofs cost more.
Yes. Re-roofing is not on the City of Idaho Falls’ list of work exempt from a building permit, so the permit is part of the cost of a replacement.
Not as a separate option. Class 4 impact-rated shingles usually cost more than standard architectural shingles, so expect a price toward the higher end of the range, and ask your insurance agent whether they offer a discount for them.
