Roof Replacement Cost in Duluth, MN (2027 Prices)
Not your house? Change the size or pitch in Duluth, MN
A roof's pitch is its rise in inches over twelve inches of run. Steeper roofs like 9/12 need roof jacks and harness work, so they cost more. We assume 7/12 for Minnesota; pick yours above.
In Duluth, MN, a typical 2,020 sq. ft. single-story house needs about $12,080 to $18,410 for a new asphalt shingle roof, old shingles off and hauled away. We get there from roughly 24.7 squares of roof (2,475 sq. ft.) pitched at 7/12; one layer comes off, and labor plus materials are in the number.
Per square - the hundred-square-foot unit every roofing bid uses - this job lands at $595.10 installed. If you want architectural 50-year shingles instead, plan on $13,420 to $20,460; metal opens at about $25,990 with steel shingles.
Compared with $11,960 to $18,230 statewide, the Duluth market adds about $150. Every one of the 12 Duluth ZIP codes in St. Louis and Saint Louis counties uses the prices on this page.

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 Duluth, MN estimates above.
Why Duluth, MN Roofing Bids Differ
A cheap bid and an expensive bid often describe two different jobs. On this 24.7-square Duluth, MN roof, these items carry real dollars:
- Old shingles. Removing the existing layer accounts for about $3,530 of the price. A hidden second layer adds roughly $2,290 more.
- Complexity. Extra ridges, valleys and dormers cost cutting time and flashing work: roughly $1,460 more for a hip design, around $2,460 more for a busy, cut-up roof.
- Building height. Same roof, two stories up: about $1,050 more, mostly labor and safety staging.
- Skylights. Swapping or adding a skylight costs around $360 each at Duluth, MN rates.
- Sheathing repairs. Soft spots in the roof deck show up during tear-off. A per-sheet price in the contract keeps that from becoming an open-ended charge.
- 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.

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 Minnesota
Averages for Minnesota: summer highs around 82°F, winter highs around 19°F, winter lows around 1°F. The map below files it under Region 1. What that means for materials and installation in Minnesota:
Ice dams. With winter lows around 1°F, eave ice is the main leak risk. Insist on ice-barrier membrane at the eaves and in every valley, then cut the attic heat loss that starts the melt. The attic insulation calculator and roof heat cable calculator cover that side.
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.
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.
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 - Minnesota 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.

Pricing a Metal Roof in Duluth, MN
Metal is not one product. Long panels, metal shingles, stone-coated tiles and copper each solve a different problem, and the price gap between them is wide.
- Standing seam: $34,640 to $52,810. This is the classic metal roof: smooth vertical panels, fasteners tucked under the seam. It suits simple roof shapes and owners who plan to stay. Over architectural shingles, expect about $25,880 more.
- Steel shingles: $25,990 to $39,610. Aluminum shingles: $28,740 to $43,800. Pressed metal pieces shaped like shakes, slate or ordinary shingles. They interlock, so they handle cut-up roofs with valleys and dormers where long panels waste metal. Aluminum will not rust, which counts near salt water. Steel is stiffer and dents less.
- Stone-coated steel: $35,370 to $53,920. 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. We do not price copper, because every copper roof is custom work. Expect it to cost well above standing seam. It is soft, formed by hand, and can last a century, turning brown and then green. Most homes use it on bay windows, porch roofs and other accents.
Ice dams are the main roof killer in Minnesota winters. A smooth metal roof sheds snow in sheets, so meltwater never gets to back up under the edge. The deck stays dry and the roof lives longer. Plan snow guards where people walk.
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.

Scheduling Your Duluth, MN Roof Job
With winter afternoons near 19°F, roofers do their best work between spring and late fall. Winter jobs are possible, but tabs may need hand sealing.
Be careful after storms: check insurance certificates, local references and licensing before any roofer starts work.
Duluth, MN Flat Roof Replacement Cost
Porches, additions, garages and some whole houses have roofs too flat for shingles; they get a membrane. Priced on the full 2,020 sq. ft. footprint in Duluth, MN:
- EPDM rubber: $16,460 to $21,380. Think of a heavy inner tube spread over the deck. The seams are glued, not welded, and over time they are its weak spot. It earns its place on small, simple roofs and in cold places.
- TPO, 60-mil: $14,170 to $18,400. A white single-ply sheet whose seams are welded with hot air into one piece. It reflects the sun and now covers most new flat roofs on homes and shops.
- PVC, 60-mil: $17,130 to $22,250. It looks like TPO but has a longer service record, and it holds up better where water sits or oils land. Choose it for a busy roof deck or a spot that never drains well.
On this footprint TPO comes in lowest, EPDM sits in the middle and PVC costs the most. Each figure covers new polyiso board under the membrane and stripping the existing layer. Small flat areas cost more per square foot, since edges, flashing and setup barely shrink. In Minnesota winters, puddles on a flat roof freeze, thaw and creep into the seams. Clear the drains often, and ask for tapered fill at any low spot during the re-roof. Need another membrane or insulation level? The flat roof calculator prices it.
Cold is hard on seams. Ask for welded TPO or PVC seams, or fully taped EPDM seams, and make sure every drain and scupper stays open when the snow melts.

Duluth, MN Roofing Questions
Will a roof replacement take more than a day?
Expect a short job for 24.7 squares of shingles - often a day or two, sometimes more. The crew should tarp or dry-in anything they open before leaving.
When does a home policy pay for roofing?
Insurance covers storm and impact damage, not wear. A worn-out roof is a maintenance cost - here about $12,080 to $18,410 for asphalt. After a storm, take photos and have a roofer look before you open a claim. Storm deductibles in Minnesota are often a percentage of coverage rather than a flat amount, so the out-of-pocket share can be large.
How do roofers measure a roof in squares?
A square is a hundred square feet of roof surface. For this 2,020 sq. ft. footprint at a 7/12 pitch, figure about 24.7 squares (2,475 sq. ft.). Use the same number when you compare bids.
What permits does a Minnesota roofing job need?
Usually. Permit rules are set locally, and most require one for a complete re-roof. A licensed roofer pulls it in their own name.

Quick Answers
Answers use Minnesota averages; energy prices updated October 2026.
What time of year is best for a new roof in Minnesota?
The warm months. With winter afternoons near 19°F in Minnesota, 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 Minnesota need an ice barrier membrane?
Yes. Minnesota averages winter lows near 1°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 Minnesota?
For long-term owners, often. Winter lows near 1°F mean snow and freeze-thaw in Minnesota; 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 Minnesota?
Only a little. Winter lows around 1°F mean heating dominates the energy bill in Minnesota; 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.
