Cost to Replace a Roof in Boise, ID (2027 Price Guide)
Use your home size and roof pitch in Boise, ID
Pitch drives both the roof area and the labor. Steep pitches (9/12 or more) slow the crew down, and low ones need extra underlayment care. Our Idaho starting value is 7/12.
In Boise, ID, a typical 2,310 sq. ft. single-story house needs about $13,450 to $20,500 for a new asphalt shingle roof, old shingles off and hauled away. That covers a 7/12 roof of about 2,830 sq. ft. - 28.3 squares - with tear-off of the current shingles, new materials and the crew.
Roofers bid by the square, which is a hundred square feet of roof; here the installed rate works out to $579.43 a square. Thicker 50-year architectural shingles raise the job to $14,950 to $22,780, and the cheapest metal choice, steel shingles, begins near $28,940.
Expect Boise bids to sit roughly $390 higher than the Idaho average of $13,140 to $20,020. Boise covers 28 ZIP codes in Ada County; roofers based anywhere in that area usually quote these prices.

Price per Year of Roof
The real cost of a roof is price divided by the years it lasts. Hover a bar: metal costs more up front and less per year.
Service lives follow the climate-bell model above (asphalt peaks in moderate regions; metal assumes correct installation); prices are the Boise, ID estimates above.
What Pushes a Boise, ID Roof Quote Up or Down
Most of the spread between roofers comes from a handful of line items. For a 28.3-square roof at Boise, ID prices:
- Layers to remove. One layer costs roughly $3,930 to take off. Older homes sometimes hide a second layer, which adds near $2,550.
- Hips and valleys. Take a basic gable as the baseline. A hip layout costs roughly $1,620 above it; dormers and valleys scattered across the roof cost about $2,740 above it.
- Access. Raise this roof a story and expect about $1,170 on top of the price, for staging, hauling and slower work.
- Roof windows. Each skylight in the scope adds roughly $350 - cheaper now than as a separate job later.
- Bad wood. Damaged decking is the most common mid-job extra. Agree on a price per sheet before work starts.
- Trim items. Chimney flashing, pipe boots, ridge vents and drip edge may or may not be in a bid. Gutters usually are not - the gutter cost calculator prices them.
- Permit and disposal. Fees depend on the town. Confirm the bid includes both the permit and the dumpster.

$16,400quotes usually $13,450 – $20,500
Same 2,830 sq. ft. roof at 7/12, priced with our roofing and metal calculators at Boise, ID rates. Decking repairs, skylights and gutters are extra.
Line the quotes up side by side: layers removed, underlayment type, ice-barrier coverage, flashing, ventilation and the decking price. The lowest bid often leaves one of those out.
Roof Stressors in Idaho
A roof in Idaho lives in Climate Region 1: about 84°F on a typical summer afternoon, about 33°F on a winter afternoon, and about 17°F on a winter night. Those numbers translate into a short list of roof stressors in Idaho:
Snow load. Deep, heavy snow tests the decking and framing as much as the shingles. During tear-off, ask the roofer to report any sagging or soft deck so it gets fixed before the new layer goes on.
Cold snaps. Repeated freezing and thawing pries at nail holes, seams and flashing. Ask for ice barrier along the eaves and new flashing everywhere the roof meets a wall.
Wildfire. Embers land on roofs and in gutters long before flames arrive. A Class A fire-rated roof covering, closed eave details and clean gutters lower the risk.
Where Shingles Live Longest: the Climate Bell
Asphalt life peaks in the moderate middle (Region 3) and falls toward BOTH ends of the map above - cold regions destroy shingles with ice dams, hot ones bake them. Note the middle columns: shingles marketed as “lifetime” are good for about 25 real-world years at best - Idaho is Region 1. Hover any column.
low pitch holds snow and ice - it costs the most years in cold regions
Planning figures from our climate model, for ventilation-correct installs - a baked, unvented attic can take years off any column. Pitch adjusts the asphalt columns only; metal sheds snow at any sane pitch.

Metal vs. Shingles in Boise, ID
Most metal bids in Boise, ID fall into one of the types below. Each line is priced for a typical 2,310 sq. ft. single-story house, the same way our metal roof calculator does it.
- Standing seam: $38,570 to $58,800. One panel covers the whole run from the ridge down to the gutter, so water has almost no joints to find. Roofers like it on low pitches and simple gables. The premium over architectural shingles here is roughly $28,820.
- Steel shingles: $28,940 to $44,110. Aluminum shingles: $32,000 to $48,770. The look of a regular roof with the life of metal. These pieces work on steep or complicated roofs. Steel resists dents; aluminum resists corrosion.
- Stone-coated steel: $39,390 to $60,040. A steel base under a granule finish. You get the tile look at a small part of the weight of real tile.
- Copper: custom quote only. A copper roof is hand work by a sheet-metal specialist, and it is priced far above standing seam. It never needs paint and weathers to a green patina. Few homes cover the whole roof with it; dormers and entry roofs are the usual places.
Metal sheds snow fast, and that starves ice dams before they start. Less ice at the eaves means fewer leaks, less rot, and a roof that lasts decades longer than asphalt in this cold. Snow guards keep the slide away from doors.
If you plan to stay a long time, metal can avoid a future re-roof entirely. Short-term owners rarely recover the extra cost. For a particular panel or coating, run the metal roof calculator.

Cold winters (highs around 33°F) push most re-roofing into the warm months, when shingle seal strips can bond. Get bids in late winter to secure a spring or summer slot.
Flat and Low-Slope Roof Prices in Boise, ID
Porches, additions, garages and some whole houses have roofs too flat for shingles; they get a membrane. Priced on the full 2,310 sq. ft. footprint in Boise, ID:
- EPDM rubber: $18,330 to $23,800. Old-school rubber roofing, and still a fair choice. It takes a hailstorm and a hard freeze in stride. The dark color soaks up sun, so it fits best where nobody lives right under it.
- TPO, 60-mil: $15,770 to $20,490. The bright white membrane on many new commercial and home flat roofs. Hot-air welded seams turn the sheets into one skin. Pick it for a sunny roof over living space.
- PVC, 60-mil: $19,070 to $24,770. PVC is the one to pay up for when the roof works hard: a deck with chairs on it, a grill, a corner that never quite dries. Its welded seams and chemical resistance outlast the cheaper sheets there.
TPO is the budget choice on this roof, and PVC sits at the top of the range. Tear-off of one existing layer and new polyiso board are part of each figure. A small section will price higher per square foot. Make sure a new flat roof drains completely; trapped water and winter freezes are a bad combination. Run the flat roof calculator to match a specific membrane and drain layout.
With winter lows near 17°F, pick the membrane for its seams and its drainage, not its color. Welded seams and tapered board at low spots keep ice out of the joints.

Roof Replacement FAQ: Boise, ID
Does a re-roof in Idaho require a permit?
Rules vary by town, but a full re-roof usually needs a permit. Expect your roofer to obtain it and to schedule any inspection.
How many squares is my roof?
Roofers measure surface, not floor area. The 2,310 sq. ft. footprint in this guide turns into about 2,830 sq. ft. of roof at 7/12 - 28.3 squares. Different counts between bids are a red flag.
How many days will my roof replacement take?
A typical 28.3-square asphalt job takes from one day to a few, depending on layers, pitch and weather. Metal and cut-up roofs take longer. Any section left open overnight should be covered.
Does homeowners insurance cover roof replacement?
If a storm caused the damage, possibly; if the roof simply wore out, no. A replacement here runs $13,450 to $20,500, so know your deductible and settlement terms before you file.

Quick Answers
Answers use Idaho averages; energy prices updated October 2026.
What time of year is best for a new roof in Idaho?
The warm months. With winter afternoons near 33°F in Idaho, shingle adhesive strips struggle to bond, so most crews book late spring into early fall; a cold-weather job needs hand-sealed tabs.
Does a new roof in Idaho need an ice barrier membrane?
Yes. Idaho averages winter lows near 17°F, cold enough for ice dams. Ask for self-adhering membrane along the eaves, in valleys and around chimneys; local code may set how far up it must run.
Does metal roofing make sense in Idaho?
For long-term owners, often. Winter lows near 17°F mean snow and freeze-thaw in Idaho; metal sheds the snow and resists both. Plan snow guards wherever sliding snow could land on people.
Will a lighter roof lower cooling costs in Idaho?
Only a little. Winter lows around 17°F mean heating dominates the energy bill in Idaho; spend first on attic insulation and air sealing.
Can new shingles go on top of the old roof?
Sometimes, if only one layer is on now and local code allows a second. A full tear-off costs more but exposes the deck, so rotted boards get replaced rather than buried.
