Roof Replacement Cost in Montana (2027 Price Guide)
Not your house? Change the size or pitch in Montana
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 Montana starting value is 7/12.
Our model puts a new asphalt roof in Montana at $12,510 to $19,070, based on a typical 2,200 sq. ft. single-story house. The roof itself measures about 2,695 sq. ft. (27.0 squares) at a 7/12 slope, and the price includes labor, materials and removal of the existing layer.
Roofers bid by the square, which is a hundred square feet of roof; here the installed rate works out to $565.83 a square. If you want architectural 50-year shingles instead, plan on $13,900 to $21,190; metal opens at about $26,910 with steel shingles.

Shingle rows use the same math as our roof replacement calculator; metal rows follow the metal roof calculator, and membranes follow the flat roof calculator. All of them carry the Mountain cost adjustment, which puts shingles and metal 5% below the U.S. average.
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 Montana estimates above.
Why Montana Roofing Bids Differ
Before you rank quotes by price, check that they cover the same work. Our model values each variable on the 27.0-square roof like this:
- Layers to remove. One layer costs roughly $3,660 to take off. Older homes sometimes hide a second layer, which adds near $2,370.
- Hips and valleys. Take a basic gable as the baseline. A hip layout costs roughly $1,510 above it; dormers and valleys scattered across the roof cost about $2,550 above it.
- Second story. Roofers charge about $1,090 more for this roof on a two-story home - longer ladders, more trips, more setup.
- Skylights. Each skylight installed or replaced during the job adds about $340.
- Decking. Nobody can see rotten plywood until the shingles come off. Get a written per-sheet replacement price so a surprise has a fixed cost.
- Flashing and ventilation. Reusing old flashing saves a little now and causes leaks later. Gutters are a separate trade line; the gutter cost calculator covers them.
- Town fees. Building permits and container rental are local costs; check whether each bid includes them.
Check a Bid Against Your Roof
Adjust the four choices below until they describe your job, then hold every quote up to the result.
$15,250quotes usually $12,510 – $19,070
Figures cover the 7/12 roof above (2,695 sq. ft.) at Montana prices; add gutters, skylights and any deck repairs separately.
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.
Weather, Wear and Your Montana Roof
Averages for Montana: summer highs around 83°F, winter highs around 31°F, winter lows around 11°F. The map below files it under Region 1. The weather above points to a few specific risks for Montana roofs.
Snow. Long-lasting snow sits on the roof and feeds meltwater into every weak spot. Snow guards over doors and walkways matter on slick metal, and decking repairs matter on any roof.
Hail. Granule loss and cracked mats from hail shorten a roof's life even when nothing leaks yet. Impact-rated products resist that, and some policies reward them.
Freeze-thaw cycles. Water that seeps into a cracked shingle or an open seam freezes at night and widens the gap. Over many winters, small openings become leaks. Ice barrier at the eaves is inexpensive protection.
Embers. In wildfire country, the roof is the largest target for flying embers. Metal, tile and fire-rated shingle systems resist ignition; ask what rating the assembly carries.
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 - Montana 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.

Is Metal Worth It in Montana?
Metal roofs come in a few families, and they do different jobs. The prices below are for a typical 2,200 sq. ft. single-story house in Montana.
- Standing seam: $35,870 to $54,680. Tall ribs, clips under the seams, nothing exposed to rust or work loose. Wide, plain roof planes show it at its best. Here it costs about $26,800 above architectural shingles.
- Steel shingles: $26,910 to $41,020. Aluminum shingles: $29,760 to $45,360. Small metal panels with a shingle or tile profile. They go on much like shingles, so hips and dormers are easier than with long panels. Pick aluminum near the ocean and steel inland.
- Stone-coated steel: $36,630 to $55,840. Steel panels covered in crushed stone and shaped like clay tile or wood shake. The texture hides hail marks and softens rain noise.
- Copper: custom quote only. Copper sits above every other metal in price and is bid job by job, so it has no line in our calculator. It is the roof of old churches and city landmarks. On a house it makes the most sense on a small, visible spot or a historic home.
Shingle roofs in Montana often fail at the eaves first, where ice builds up and water backs in. Metal is slick, so snow lets go before that ice ridge can form. The edge stays sound, and the roof can go two or three times as long as asphalt.
Owners who stay put get the most from metal, because the long service life is where the savings sit. Want a firmer metal number? Try the metal roof calculator with your measurements.

Best Season for a New Roof in Montana
With winter afternoons near 31°F, roofers do their best work between spring and late fall. Winter jobs are possible, but tabs may need hand sealing.
After a big storm, out-of-area crews go door to door. Before signing, confirm liability and workers' compensation insurance, a local address, and any license your state or town requires.
Flat and Low-Slope Roof Prices in Montana
A flat roof the size of this home's 2,200 sq. ft. footprint would run, in Montana:
- EPDM rubber: $17,040 to $22,140. This is the black rubber sheet on many older flat roofs. Big sheets mean few seams. It stays soft in deep cold and any roofer can patch it, which makes it a good fit for a garage or a back porch.
- TPO, 60-mil: $14,670 to $19,050. Most roofers reach for TPO first today. It is white, light, and the seams are melted together rather than glued. Thicker sheets last longer, so compare the mil rating on each bid.
- PVC, 60-mil: $17,740 to $23,040. Also white and heat-welded, but tougher against grease, chemicals and standing water. It is the pick for roof decks, low spots that hold puddles, and anything near a kitchen exhaust.
On this footprint TPO comes in lowest, EPDM sits in the middle and PVC costs the most. Both insulation board and old-layer removal are in the numbers. Per square foot, small flat roofs cost noticeably more than large ones. Water that pools and freezes on a flat roof opens seams over time. Re-roofing is the moment to fix low spots with tapered board. Run the flat roof calculator to match a specific membrane and drain layout.
With winter lows near 11°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: Montana
How do I estimate my roof size?
A square is a hundred square feet of roof surface. For this 2,200 sq. ft. footprint at a 7/12 pitch, figure about 27.0 squares (2,695 sq. ft.). Use the same number when you compare bids.
How many days will my roof replacement take?
Most shingle re-roofs on a house this size (2,695 sq. ft. of roof) finish within a few working days. Extra layers, steep pitch or rain add time; metal takes longer.
When does a home policy pay for roofing?
Only for sudden damage such as wind, hail or a falling tree, never for plain wear. Certain policies cover an aging roof at its depreciated worth rather than full replacement. On a roof that costs $12,510 to $19,070 to replace, that gap is large, so check your settlement terms. Storm deductibles in Montana are often a percentage of coverage rather than a flat amount, so the out-of-pocket share can be large.
What permits does a Montana roofing job need?
In most places, a complete replacement needs a permit and may need an inspection. Your roofer should apply for it; a request that you do it yourself is a warning sign.
