Roof Replacement Cost in New Hampshire (2027 Price Guide)
Reprice this page for your own roof in New Hampshire
Not sure of the pitch? Most ranch homes sit low; a roof you cannot walk on, such as 9/12 and up, adds safety gear and labor. This page starts New Hampshire at 7/12.
In New Hampshire, a typical 1,930 sq. ft. single-story house needs about $12,380 to $18,860 for a new asphalt shingle roof, old shingles off and hauled away. That covers a 7/12 roof of about 2,364 sq. ft. - 23.6 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 $638.16 a square. Thicker 50-year architectural shingles raise the job to $13,750 to $20,960, and the cheapest metal choice, steel shingles, begins near $26,630.

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 New Hampshire estimates above.
Reading a New Hampshire Roofing Quote Line by Line
Before you rank quotes by price, check that they cover the same work. Our model values each variable on the 23.6-square roof like this:
- Tear-off. About $3,620 of the quote pays to strip and dispose of one layer; if the roofer finds two layers, figure another $2,350 or so.
- Roof shape. When every side of the roof slopes down to a gutter (a hip design), add close to $1,490 over a two-sided gable. Plenty of dormers and valleys raise the add-on to about $2,520.
- Height. A second story adds roughly $1,070 to the same roof, because every bundle goes higher and safety setup takes longer.
- Skylights. Swapping or adding a skylight costs around $390 each at New Hampshire 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.
- 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, dumpster, cleanup. Each town sets its own fees. Get them written into the price, along with a magnetic nail sweep of the yard.

Compare scope first and price second. A bid that skips new flashing or a decking allowance only looks cheaper.
What the New Hampshire Climate Does to Roofing
New Hampshire's winters average highs near 29°F and lows near 10°F; summer highs average about 81°F. On our climate map below, that puts it in Region 1. Below are the stresses that matter most for a New Hampshire roof, and what to ask for because of them.
Ice dams. With winter lows around 10°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.
Thaw damage. Meltwater that refreezes in gutters and seams expands and opens them a little more each time. Keep gutters clear and have every flashing joint redone during the re-roof.
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 - New Hampshire 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 New Hampshire?
A metal roof on a typical 1,930 sq. ft. single-story house in New Hampshire starts at $26,630. The type you pick matters more than the brand, so here is how the main options differ.
- Standing seam: $35,490 to $54,100. Long panels run from ridge to eave and lock together at raised seams, with the clips hidden underneath. No screws go through the face, so there are far fewer places for a leak to start. On this roof it runs about $26,520 more than architectural shingles.
- Steel shingles: $26,630 to $40,590. Aluminum shingles: $29,440 to $44,880. 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: $36,240 to $55,250. 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 has no price in our tools: each job is a custom quote, and it runs well past standing seam. In return it can outlive the house. Use it where people will see it, like a front porch or a turret.
Shingle roofs in New Hampshire 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.
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 New Hampshire Roof Job
Cold winters (highs around 29°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 New Hampshire
Porches, additions, garages and some whole houses have roofs too flat for shingles; they get a membrane. Priced on the full 1,930 sq. ft. footprint in New Hampshire:
- EPDM rubber: $16,860 to $21,900. 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: $14,520 to $18,850. 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: $17,550 to $22,790. 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.
Ranked by price for this home, TPO is cheapest, EPDM is next, 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. In New Hampshire 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. For thicker insulation or a different membrane, use the flat roof calculator.
Snow load and slow melt are the test in New Hampshire. Any of the three can pass it if the seams are done right and the water has a clear path off the roof. Ask how the bid handles drains and low corners.

Common Questions About Re-Roofing in New Hampshire
How many squares is my roof?
Start with the area under the roof, including garages and porches, then allow for slope and waste. A 1,930 sq. ft. footprint at 7/12 becomes roughly 23.6 squares (2,364 sq. ft.). Compare bids on the same count.
How long does a re-roof take?
For roughly 23.6 squares, a full crew usually finishes asphalt in a few days. Metal panels and roofs with many valleys take longer.
Will insurance pay for my new roof?
Insurance covers storm and impact damage, not wear. A worn-out roof is a maintenance cost - here about $12,380 to $18,860 for asphalt. After a storm, take photos and have a roofer look before you open a claim.
Should my roofer get a permit in New Hampshire?
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.
