Where the numbers come from

How we measure your roof

  1. 1
    Aerial LiDAR
    USGS aerial LiDAR flown September 2023 to August 2024, about 16 points per square meter, gives every roof plane its size, pitch and edges.
  2. 2
    County aerial photos
    Ada and Canyon County aerial imagery flown 2025 at 3 inch resolution shows the roof as it is now.
  3. 3
    AI separates what is not your roof
    Patio covers, carports, gazebos and neighboring roofs are detected and left out of the count.
  4. 4
    You can correct the outline
    The measured outline is drawn on the photo. Tap a section to remove it, or tap a dashed one to add it back.
  5. 5
    An itemized estimate, then a real measurement
    You get an itemized estimate with the breakdown under it, shown as a narrow range. A local roofing pro measures on site before any contract.

Where LiDAR has not been flown yet, the estimate comes from aerial imagery alone and is labeled that way.

Treasure Valley

Roof replacement cost across Idaho

A typical home's replacement span in each city we serve, from 3-tab to designer asphalt shingles, updated September 2026. Each page carries the cost-by-size table for that city.

Why this number is lower than other Boise roof cost guides

This site prices from a partner price book (Bork Roofing) at an all-in rate per square, $380 to $410 installed for GAF Timberline HDZ, covering installation, tear-off of one existing layer, starter strip and drip edge, ridge cap, ice and water shield, standard flashing and pipe boots, disposal, steep-slope labor up to 8/12. Guides that quote a wider span average many bids with many markups.

The number is for the measured roof, not the floor area: a typical 1,800 square foot home in Boise carries about 22 squares of roof, which is where $5,900 to $10,900 comes from; the estimator measures yours.

Add-ons other guides fold into an average are itemized only when they apply: extra tear-off layers ($45 per square for each existing layer beyond the first); steep pitch ($35 per square on planes steeper than 8/12); decking (2 sheets included, then $95 per sheet); permit (the city's own fee where it is on file, else a $150 allowance).

Outside reference: This Old House, Cost of Roof Replacement in Idaho puts the Idaho average at $7,947 as of May 2026 ($6,117 to $20,703 statewide); a typical Boise home at $5,900 to $10,900 sits inside that span.

Common Questions

Roofing Cost FAQs

As of September 2026, a roof replacement in Boise runs about $5,900 to $10,900 for a typical 1,800 square foot home (22 squares of roof). A smaller home (under 1,200 sq ft) runs $3,700 to $6,600 in asphalt. Larger homes (2,500 to 3,500 sq ft) reach $8,000 to $17,200 depending on pitch, complexity, and material. Architectural shingles (GAF Timberline HDZ) are $380 to $410 per square installed and are the most popular choice in Treasure Valley.
Enter your street address and RoofMetric measures the roof from aerial LiDAR and county aerial imagery, then shows an itemized estimate in 60 seconds, any time. No appointment, no salesperson, no credit card. A registered local contractor still measures on site before any contract; the price is for planning.
It depends on the cause. Storm damage (hail, wind) is typically covered by standard homeowner's policies in Idaho. Wear-and-tear or age-related deterioration is generally not covered. Treasure Valley sees significant hail activity from April through July, the leading cause of roof insurance claims in Ada and Canyon Counties. RoofMetric's free estimate helps you document scope before filing a claim.
Standard 3-tab asphalt shingles last 15 to 20 years in Idaho's climate. Architectural (dimensional) shingles last 20 to 30 years. Metal roofing can last 40 to 70 years. Treasure Valley's high UV, summer heat, and spring hail accelerate shingle wear compared to milder climates. Roofs 15+ years old should be inspected annually, especially after hail events.
The roof is measured from USGS aerial LiDAR flown September 2023 to August 2024, about 16 points per square meter, and Ada and Canyon County aerial imagery flown 2025 at 3 inch resolution, and the measured area is shown as one number with its squares and a confidence note. The estimate is itemized from the price book and shown as a narrow range: billable squares (measured squares plus waste from the measured hips and valleys) times an all-in per-square price, plus only the true add-ons: extra tear-off layers, steep planes over the included pitch, decking beyond the included sheets, and the permit. The measurement is being validated against contractor invoices now. Where LiDAR has not been flown, the estimate comes from aerial imagery alone and is labeled that way. The measurement cannot see the number of shingle layers, decking damage or a contractor's own pricing, so a local roofing pro measures on site before any contract.
Usually have it inspected first: a roof that age is near the end of an asphalt shingle's expected life, but only the shingles' condition says whether it is done. On Boise's steep-pitch historic bungalows, low-slope mid-century ranches, and everything between, replace it when the field is losing granules, curling or leaking in more than one place, and repair it when the damage is isolated; a free inspection gives that answer with photos.
The 25% rule is a rule of thumb: once more than a quarter of a roof needs repair, replacing the whole roof usually costs less than patching it. It began as a building-code threshold in some states, not Idaho, so in Boise it is a budgeting test, not a permit rule. Repairs start from $149; if several are due at once on an aging roof, compare their total with the itemized replacement price.
In Boise, about $6,100 to $9,000 with GAF Timberline HDZ, or $4,300 to $5,900 in 3-tab, as of September 2026. That is the 16 to 22 squares of roof surface a home of that size usually carries; metal for the same roof runs $6,800 to $17,000. On steep-pitch historic bungalows, low-slope mid-century ranches, and everything between, the estimator replaces the assumption with your measured roof.
Shingles are cheaper up front: GAF Timberline HDZ is $380 per square installed against $425 for exposed-fastener metal and $775 for standing seam. Metal lasts longer and pencils out for owners who plan to stay; for a shorter hold, architectural asphalt stays the Boise default on steep-pitch historic bungalows, low-slope mid-century ranches, and everything between.
