Most asphalt roof replacements in New Hampshire cost $14,000 to $25,000 in 2026. That works out to about $6.00 to $8.50 per square foot installed for architectural shingles, with tear-off, ice and water shield, ventilation and cleanup included. Size, pitch, how cut-up the roof is and what’s under the old shingles decide where your house lands.

BBB A+ AccreditedNobody calls us because they want to spend $20,000. They call because the ceiling has a stain, the shingles are shedding granules into the gutters, or a home inspector flagged the roof. The first question is always the same: what’s this going to cost?
We’re Compass Exteriors, a family-owned roofing company based in Stratham, and we price roof replacements every week across southern New Hampshire, northern Massachusetts and southern Maine. The numbers on this page are the ranges we quote and install at. Your roof will have its own number, and the only way to get it is to measure the roof in person. This page explains what goes into that number so the estimate makes sense when you see it.
For architectural asphalt shingles, budget $6.00 to $8.50 per square foot of roof, or $600 to $850 per square. On a typical New Hampshire house with 2,300 to 3,000 square feet of roof, that’s roughly $14,000 to $25,000. Standing seam metal runs about $14 to $20 per square foot.
Roofers price in squares. A square is 100 square feet of roof surface, so a 2,500-square-foot roof is 25 squares. Keep in mind that roof area isn’t the same as your home’s floor area. Pitch adds surface, and a steep colonial has a lot more roof than a ranch with the same footprint. That’s why online calculators miss so often.
The table shows how those per-square-foot ranges play out by roof size. These are the installed ranges we quote. They’re not a quote for your house.
| Roof area (squares) | Architectural asphalt ($6.00–$8.50/sq ft) | Standing seam metal ($14–$20/sq ft) |
|---|---|---|
| 1,500 sq ft (15) | $9,000 – $12,750 | $21,000 – $30,000 |
| 2,000 sq ft (20) | $12,000 – $17,000 | $28,000 – $40,000 |
| 2,500 sq ft (25) | $15,000 – $21,250 | $35,000 – $50,000 |
| 3,000 sq ft (30) | $18,000 – $25,500 | $42,000 – $60,000 |
Nearly every roof we replace is architectural (dimensional) asphalt. Basic 3-tab shingles are cheaper by $1 to $2 per square foot installed, but they’re thinner, carry lower wind ratings and wear out years sooner. On a house you plan to live in, the architectural shingle usually costs less per year of service. Our asphalt shingle roofing page covers the systems we install.
Older homes are their own category. On a pre-1930 Seacoast house, the old-house work (extra layers, plywood overlay, chimney repairs, adding ventilation) often pushes the total to $18,000 to $32,000. We wrote up what we find on those roofs in roofing a 100-year-old Seacoast home.
A full replacement should include tear-off to the deck, disposal, decking repairs at a stated per-sheet price, ice and water shield, synthetic underlayment, drip edge, new flashing, ridge ventilation, shingles, ridge cap and cleanup. If a line isn’t on the estimate, assume it isn’t in the price.
On our roofs, that means the old roofing comes off down to the wood, and we check every sheet of decking before anything new goes on. Ice and water shield goes in at the eaves and valleys, synthetic underlayment covers the rest of the deck, and new drip edge and flashing go in at every edge, wall, chimney and pipe. We don’t reuse tired metal to save an hour. Then come the shingles, the ridge vent and the ridge cap. Materials, labor, disposal and the permit are all on the estimate as their own lines.
The step-by-step version is in what happens during a roof replacement.
Shingles are a small part of the bill. Materials as a whole run about 35 to 40 percent of a typical replacement. Labor, disposal, permits and overhead make up the rest.
A bundle of architectural shingles costs roughly $40 to $60 at New Hampshire suppliers, and three bundles cover a square. That’s about $120 to $180 per square for the shingle itself, against $600 to $850 per square installed. People are surprised by that gap until they see what else goes into the job. Underlayment, ice and water shield, drip edge, flashing, ventilation and fasteners all cost money. The labor cost is mostly about height and pitch. A crew strips the old roof, rebuilds the flashing, installs everything in the right order and hauls away two to three tons of debris, usually in a day or two.
This is also why the brand of shingle matters less than people expect. Between the major manufacturers, the price gap on a full job is usually a few hundred dollars. We compared them in GAF vs. Owens Corning vs. CertainTeed.
Size, pitch and complexity set most of the price. After that, it’s how many old layers come off, how much decking needs replacing, and add-ons like skylights, chimney work and extra ventilation.
Pitch. A walkable roof up to about 7/12 gets standard pricing. Steep roofs from 8/12 to 10/12 add roughly 10 to 15 percent for staging and safety setup, and very steep roofs at 11/12 and up add 20 to 30 percent. A lot of Seacoast colonials and Victorians are in that steep range.
Complexity. A simple two-plane gable is the cheapest roof per square. Every valley, dormer, hip and wall line adds cutting, flashing and time. Expect 10 to 25 percent more for a moderately cut-up roof and 25 to 40 percent more for a roof with a lot going on.
Old layers. Each extra layer of shingles under the top one adds about $30 to $60 per square to tear off and haul away. We tear off to the deck on every replacement. New Hampshire’s building code is based on the International Residential Code, per the NH Building Officials Association, and the IRC doesn’t allow a re-cover over a roof that already has two layers.
Decking. Nobody knows what the deck looks like until the shingles are off. Replacing bad sheets runs about $70 to $120 per 4×8 sheet installed, and most re-roofs need somewhere between zero and six. A full redeck adds roughly $5,000 to $9,000 on a typical home. Our post on rotted roof decking shows what we look for.
Add-ons. Replacing skylights during the re-roof runs about $700 to $1,800 each. Proper flashing work adds $400 to $1,500 on most homes. Cutting in soffit vents where there are none runs $300 to $800. All of these should be separate lines on the estimate so you can see what you’re paying for.
Across our service area, labor and material costs are close. What changes is the scope: coastal homes need corrosion-resistant metals, Lakes Region roofs need more ice protection, and old houses need more carpentry.
On the Seacoast, homes close to the water often need aluminum or stainless components and fasteners, which adds about $1,500 to $2,500. We cover the rest in coastal roof replacement on the Seacoast. The same applies on the southern Maine coast, from Kittery Point up to York.
In the Lakes Region and inland, deep snow and long freeze-thaw stretches make ice dams the main concern. We put two rows of ice and water shield at the eaves and run it the full length of every valley on every replacement we do. See ice dams on New Hampshire roofs for why.
In northern Massachusetts, the main differences are permit fees and requirements, which vary from town to town. Older mill-town houses also tend to need more decking work.
Standing seam metal costs about two to three times as much as architectural asphalt up front. It also lasts 50 to 70 years, against roughly 20 to 25 for asphalt, so over the life of the house the gap gets much smaller.
Standing seam runs about $14 to $20 per square foot installed, and stamped steel such as EDCO runs about $12 to $18 or more. Spread the cost over the years you get from each roof and the gap narrows. A $20,000 asphalt roof that lasts 27 years costs about $740 a year. A $42,000 steel roof that lasts 50 years costs about $840 a year, and you never pay for the next tear-off.
Metal makes the most sense if you plan to stay in the house for a long time, if snow load or ice is a constant fight, or if you just never want to re-roof again. If you’re selling in a few years, asphalt is usually the better buy. Compare them in asphalt vs. metal roofing in NH, or read the standing seam cost guide and our page on EDCO steel roofing. Everything we install in metal is on the metal roofing page.
Because roofing materials and labor go up almost every year. If your roof is near the end of its life anyway, waiting rarely makes it cheaper, and a slow leak can add decking and interior repairs to the bill.
Our suppliers send price-increase letters most years, sometimes twice. On March 5, 2026, ABC Supply notified contractors that steep-slope roofing and accessories would go up 6 to 10 percent on April 15. Every contractor in New England got a similar letter. It shows up in every quote written after the increase takes effect.
Take a roof we’d price at $15,000 today. This is an illustration, not a quote. It assumes materials are about 40 percent of the job and rise 8 percent a year, and labor and overhead are the other 60 percent and rise 4.5 percent a year.
| Year | Same roof |
|---|---|
| 2026 | $15,000 |
| 2027 | $15,885 |
| 2028 | $16,827 |
| 2029 | $17,829 |
That’s $2,829 more for the same roof three years out, about 19 percent. Your actual number depends on your roof, the materials and the market.
There’s a flip side. If your roof has five good years left, waiting is the right call, and we’ll tell you so. Our guide to repair vs. replacement walks through how we decide. Most targeted repairs run about $400 to $1,500, and our roof repair page covers what we fix.
Compare the scope, not just the total. Two quotes for “the same roof” can be thousands of dollars apart because one includes ice and water shield, synthetic underlayment, new flashing and a per-sheet decking price, and the other leaves them out.
A $16,000 quote that skips ice and water shield, uses felt instead of synthetic underlayment and puts builder-grade shingles over old flashing isn’t the same product as a $22,000 quote with full ice and water coverage, synthetic underlayment, new flashing and proper ventilation. The cheaper one may cost more by the time it’s done.
A quote worth signing names the shingle manufacturer and product line. It spells out where the ice and water shield goes, what underlayment is used, whether the drip edge and flashing are new, what ridge vent goes on, and what the warranty covers. It gives a per-sheet decking price in writing before the roof is opened, because once the old shingles are off, you’re negotiating with your roof open. It also comes from someone who got on your roof, not someone working from a drone photo or satellite measurement. Your contractor should pull the permit. If they ask you to pull it, ask why.
The ridge vent alone is a place where bids get shaved. We explain that one in Cobra roll vs. filtered ridge vent, and the common mistakes in 7 roofing mistakes NH homeowners make.
Most homeowners use savings, a home equity line or contractor financing. Through third-party lenders, we offer $0 down, 0% interest for 12 months, or terms up to 10 years if you qualify. The lender sets the terms and makes the approval decision.
If you qualify, you can lock in today’s price and pay for it over time.
Financing’s through third-party lenders, subject to credit approval. Terms and rates are up to the lender, not us. Not everyone qualifies for every offer.
Whatever financing you use, compare the total cost, not just the monthly payment. If a 0% offer is a deferred-interest promotion, the Consumer Financial Protection Bureau explains how it works: if the balance isn’t paid in full by the deadline, interest can be charged back to the original purchase date. Ask before you sign. More details are on our financing page.
It returns part of its cost, not all of it. In the 2025 Cost vs. Value Report, an asphalt roof replacement recouped about 68 percent of its cost nationally and about 63 percent in New England. A worn roof also tends to come up in the buyer’s inspection.
The 2025 Cost vs. Value Report from the Journal of Light Construction puts an asphalt roof replacement at 67.5 percent cost recouped nationally and 62.6 percent in the New England region. Metal roofing recouped less at resale, 50.1 percent nationally and 38.9 percent in New England. That fits what we tell people: metal pays off by lasting, not at the closing table.
The bigger reason to replace a roof before selling is the inspection. A roof near the end of its life gives buyers a reason to ask for a credit or walk away. Our roof inspection guide covers what inspectors look for.
Larger asphalt shingle projects for condo associations, apartment owners and churches are priced building by building after an on-roof inspection of each structure. There isn’t a fair per-house number for these jobs, because phasing, access and occupancy change the scope.
We inspect every building and document it with photos and narrated video, so a property manager can hand the board a clear, shareable report. Then we build a phasing plan that works around residents or services and keep everyone updated as the work moves building to building. See commercial asphalt shingle roofing for how we run those projects.
If the siding or windows are also near the end of their life, it’s worth pricing them at the same visit so the roof-to-wall flashing and trim details get planned together.
Our siding replacement cost guide lays out 2026 siding prices in New Hampshire, and our windows and doors page covers the replacement windows we install.
We climb the roof, walk every slope and record a narrated video of what we find. You get the video, photos and an itemized, fixed-price estimate. They’re yours to keep, hire us or not.
Most roofers look at your roof from the ground. Or send a drone. Or grab a photo and guess. We climb up, walk every slope, and record the whole thing with narrated explanations so you can see and understand exactly what we find.
Most roofers look from the driveway or send a drone. We get on the roof, because that’s the only way to see soft decking, failed flashing and shingles that never sealed. The estimate lists every line, with no “miscellaneous.” If something comes up mid-job, we tell you before we touch it.

“Ben and his team were outstanding from start to finish. They did a thorough inspection, explained everything clearly, and completed our roof replacement in just two days. The quality of work is exceptional.”
“Transparent about everything — pricing, materials, timeline. No pressure at all. They found issues with our decking that the previous roofer missed.”
“Professional from beginning to end. The crew showed up on time, protected our landscaping, and the new seamless gutters look fantastic. Fair pricing and no surprises.”

Full asphalt shingle tear-off and replacement. New ridge venting, upgraded flashing throughout. Two days, start to finish.
Late spring through early fall is the busiest season, and the calendar fills fast. We install through most of the winter as well, on days when it’s dry and warm enough for the shingles to seal.
If the roof is leaking or the deck is soft, don’t wait for spring. Our post on the best time to replace a roof in NH goes season by season.
Most architectural asphalt roof replacements in New Hampshire run $14,000 to $25,000, or about $6.00 to $8.50 per square foot installed. Roof size, pitch, complexity and decking condition decide where a house lands. Standing seam metal runs about $14 to $20 per square foot.
About $600 to $850 per square installed for architectural asphalt shingles. A square is 100 square feet of roof surface. The shingles themselves are only about $120 to $180 of that. The rest is underlayment, flashing, ventilation, tear-off, disposal and labor.
About $70 to $120 per 4×8 sheet installed during a re-roof. Most re-roofs need zero to six sheets. A full redeck runs roughly $5,000 to $9,000 on a typical home. Get the per-sheet price in writing before work starts.
Not if the roof already has two layers, which the building code doesn’t allow, or if the old roof is soaked or deteriorated. We tear off to the deck on every replacement, so the decking can be checked and the ice and water shield goes down on bare wood.
Ours is free, with a narrated video and an itemized estimate you keep. A standalone certified inspection with a written condition report, the kind often used in a home sale, typically runs $150 to $450 in New Hampshire.
Most asphalt roof replacements on a typical home are done in one to two days. Larger or more complex roofs can take three to four days, and standing seam metal usually takes three to five.
It adds value but doesn’t pay for itself. The 2025 Cost vs. Value Report puts an asphalt roof replacement at about 68 percent of cost recouped nationally and about 63 percent in New England. A new roof also removes a common objection in the buyer’s inspection.
Yes. Through third-party lenders, we offer $0 down, 0% interest for 12 months, or terms up to 10 years if you qualify. The lender sets the terms and decides approval. We’ll go over the options at the inspection, and there’s nothing to sign until you’ve seen the numbers.
A range is a starting point. Your price comes from measuring your roof, checking the attic and looking at what’s under the shingles.
