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 Great Falls, MT estimates above.
Reading a Great Falls, MT Roofing Quote Line by Line
Line items, not markup, explain most bid gaps. Priced on the 27.0-square roof in this guide:
- Old shingles. Removing the existing layer accounts for about $3,680 of the price. A hidden second layer adds roughly $2,380 more.
- Hips and valleys. Take a basic gable as the baseline. A hip layout costs roughly $1,520 above it; dormers and valleys scattered across the roof cost about $2,560 above it.
- Stories. Put this roof on a two-story house and the bid rises by about $1,090 for the extra climbing, staging and hauling.
- Skylights. Swapping or adding a skylight costs around $340 each at Great Falls, MT rates.
- Roof deck. Ask every bidder for a per-sheet plywood or OSB price. It turns the biggest unknown on the job into a known number.
- 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.
- Permit and disposal. Fees depend on the town. Confirm the bid includes both the permit and the dumpster.

What the Montana Climate Does to Roofing
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. Below are the stresses that matter most for a Montana roof, and what to ask for because of them.
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.
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 risk. Debris in gutters and valleys catches embers easily. Choose a fire-rated covering, keep the roof clean, and ask about screened, ember-resistant vents.
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.

Metal vs. Shingles in Great Falls, MT
Metal costs more on day one and less for each year the roof lasts. Here is what each type would cost on a typical 2,200 sq. ft. single-story house in Great Falls, MT, and where each one makes sense.
- Standing seam: $36,050 to $54,960. 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 $26,940 above architectural shingles.
- Steel shingles: $27,050 to $41,230. Aluminum shingles: $29,910 to $45,590. 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: $36,820 to $56,120. 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. Copper is a craft job, so we leave it out of the calculator and you will need a custom bid. It costs the most of any metal by a wide margin. A small copper accent over a bay window gives you the look without the whole-roof bill.
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.
Think about your timeline: metal's higher price spreads across many more years, but only if you are there to use them. Use the metal roof calculator to price your exact panel type.

Roofing Season in Great Falls, MT
Cold winters (highs around 31°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.
Storm chasers follow hail and wind. Hire a roofer with a local office and proof of insurance, and never sign over insurance proceeds on the spot.
Membrane Roof Costs in Great Falls, MT
Membrane roofing covers what shingles cannot: flat porches, garages, additions and row-house tops. On a 2,200 sq. ft. footprint:
- EPDM rubber: $17,130 to $22,250. A rubber membrane with a long track record. It comes in large rolls, so a small roof may need no seam at all. Choose it where the roof is shaded or out of sight and the winters are hard.
- TPO, 60-mil: $14,740 to $19,150. 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: $17,830 to $23,150. A flexible white sheet with welded seams that has kept flat roofs dry for decades. It handles ponding water and grease better than the other two.
Ranked by price for this home, TPO is cheapest, EPDM is next, and PVC costs the most. Tear-off of one existing layer and new polyiso board are part of each figure. A small section will price higher per square foot. 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. For thicker insulation or a different membrane, use the flat roof calculator.
In Montana winters a dark EPDM roof picks up a little sun warmth, which helps snow melt off. Drainage matters more: water that freezes in a low spot pries seams apart.

Before You Re-Roof in Great Falls, MT
How do roofers measure a roof in squares?
Measure the area the roof covers, then scale it up for slope. The 2,200 sq. ft. footprint in this guide, sloped at 7/12, grows to near 2,695 sq. ft. - 27.0 squares once overhang and waste are counted. Ask each roofer for their square count in writing.
What permits does a Montana roofing job need?
Rules vary by town, but a full re-roof usually needs a permit. Expect your roofer to obtain it and to schedule any inspection.
Will insurance pay for my new roof?
Covered: hail, wind, fallen trees. Not covered: age and wear. With asphalt at $12,570 to $19,160 in Great Falls, MT, it pays to read your roof settlement terms now, not after a storm. Storm deductibles in Montana are often a percentage of coverage rather than a flat amount, so the out-of-pocket share can be large.
How many days will my roof replacement take?
Expect a short job for 27.0 squares of shingles - often a day or two, sometimes more. The crew should tarp or dry-in anything they open before leaving.

Quick Answers
Answers use Montana averages; energy prices updated October 2026.
What time of year is best for a new roof in Montana?
The warm months. With winter afternoons near 31°F in Montana, 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 Montana need an ice barrier membrane?
Yes. Montana averages winter lows near 11°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 Montana?
For long-term owners, often. Winter lows near 11°F mean snow and freeze-thaw in Montana; 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 Montana?
Only a little. Winter lows around 11°F mean heating dominates the energy bill in Montana; 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.
