Roof Replacement New Hampshire
When repairs stop being worth the money, a full replacement is the fix. We tear off to the deck, build it back properly for New Hampshire weather, and hand you a written warranty before we leave.
What We Do
Full Roof Replacement, Done by Our Own Crew
A roof replacement is the single biggest exterior investment most homeowners make, and it is one of the easiest to get wrong. Shortcuts hide under the shingles for years before they show up as a stain on a bedroom ceiling.
Vincenzo’s Roofing replaces residential and commercial roofs across New Hampshire, from Seacoast capes to multi-unit buildings inland. Every job is a complete tear-off down to the decking — we never lay new shingles over old ones, because it hides rot, voids most manufacturer warranties, and shortens the life of the roof you just paid for.
The crew that quotes your roof is the crew that installs it. No subcontractors, no handoff to a team you have never met, and no surprise line items between the estimate and the invoice.
Repair or Replace?
Signs It’s Time to Replace Your Roof
One or two of these usually means a repair will do. Several at once, or any of them on a roof past twenty years, and replacement is almost always the better spend.
Curling or cracked shingles
Edges lifting or corners cupping means the shingle has lost its flexibility and no longer seals against wind-driven rain.
Granules in your gutters
Those dark sandy deposits are the shingle’s protective layer washing away. Once it is gone, UV breaks down what is left quickly.
Leaks in more than one place
A single leak is a repair. Water showing up in separate areas usually means the system has failed, not one flashing detail.
A sagging or spongy deck
Dips along the roofline mean moisture has reached the sheathing. This one does not wait — the damage spreads under the surface.
Daylight through the attic
If you can see light between the boards from inside, water and cold air are getting in the same way.
Twenty years or older
Most asphalt roofs in New Hampshire reach the end of their service life somewhere between twenty and twenty-five years.
Not sure which side of the line you are on? Our
free roof inspection gives you an honest answer in writing — including when the answer is
“this roof has five good years left.”
Scope of Work
What’s Included in a Vincenzo’s Roof Replacement
Every replacement we quote includes the following as standard. If a competitor’s number comes in lower, this list is usually where the difference is hiding.
- Complete tear-off to the bare deck, all layers removed
- Full deck inspection with rotted sheathing replaced
- Ice-and-water shield at eaves, valleys, and penetrations
- Synthetic underlayment across the entire roof
- New drip edge, step flashing, and pipe boots
- Ridge vent and intake ventilation balanced for the attic
- Starter strip and manufacturer-spec nailing pattern
- Daily magnetic nail sweeps and full debris haul-away
- Building permit pulled and final inspection handled
- Written warranty registered at final walkthrough
Your Options
Choosing Your Roofing Material
Two materials cover the vast majority of New Hampshire replacements. The right answer depends on how long you plan to stay, your roof’s pitch, and how exposed the house is.
Architectural asphalt shingles
The default for most homes, and for good reason: strong value, a wide colour range, and a 25–30 year service life when installed correctly. Near the coast or on exposed hillsides we specify a higher wind rating rather than the builder-grade product most quotes assume.
Standing-seam metal
Costs more up front and pays it back over forty-plus years. Metal sheds snow before it can build into an ice dam and holds up far better against coastal salt air. Worth serious consideration if you are staying in the house long term.
A note on warranties
Manufacturer warranties cover defects in the material itself. They do not cover installation errors — and an improper install can void them entirely. That is why our 25-year workmanship warranty is separate and written down: between the two, you are covered on both sides.
Straight Pricing
How Much Does a Roof Replacement Cost in New Hampshire?
That is the honest range for most New Hampshire homes. A small ranch with a simple gable roof sits near the bottom; a large colonial with multiple dormers, steep pitch, and metal roofing sits at the top. We would rather you see the range now than find it out after an hour-long sales visit.
- Size and pitch — square footage plus how steep the roof is to work on safely
- Material choice — asphalt vs. metal is the single biggest swing
- Existing layers — two or three old layers means more tear-off and disposal
- Deck condition — rotted sheathing found during tear-off is replaced at cost
- Complexity — dormers, valleys, skylights, and chimneys all add flashing work
- Access — tight lots and steep driveways affect staging and cleanup time
How It Works
Your Roof Replacement, Step by Step
Free inspection
We get on the roof, photograph what we find, and tell you honestly whether you need a replacement yet.
Written estimate
An itemized quote with materials, labour, permit, and a realistic start and finish window. No pressure to sign.
Schedule & permit
We lock in dates, pull the town permit, and order material so nothing stalls once the roof is open.
Tear-off & install
Usually one to three days. We text you updates and flag anything unexpected found under the old shingles.
Final walkthrough
We walk the finished roof with you, clear the site, and register your warranty before pulling out of the driveway.
Local Expertise
Built for New Hampshire Weather
A roof in Seabrook takes a different beating than one in Manchester. We build for what is actually hitting your house.
Salt air on the Seacoast
Within a few miles of the water, salt corrodes fasteners, flashing, and drip edge far faster than inland. On coastal jobs we specify corrosion-resistant components instead of the standard galvanised most crews default to.
Coastal wind exposure
Open stretches near the shore see gusts that lift improperly nailed shingles. Correct nailing pattern, starter strip, and a shingle rated for the exposure matter far more here than the brand on the bundle.
Ice dams and freeze-thaw
Meltwater refreezes at the cold eave and backs up under the shingles. Ice-and-water shield at eaves and valleys, plus balanced attic ventilation, is what actually stops it.
Snow load and spring melt
Heavy wet snow followed by a fast thaw finds every weak flashing joint and overwhelms undersized drainage. We size gutters for the melt, not for average rainfall.

FAQ
Asphalt Shingle Questions
Most full roof replacements in New Hampshire run between $8,000 and $22,000. The main cost drivers are roof size and pitch, the material you choose, how many old layers need removing, and whether any decking underneath has rotted and needs replacing. We give you an itemized written estimate after an on-site inspection.
Most residential roof replacements in New Hampshire are finished in one to three days, weather permitting. Steeper or larger roofs, and homes with multiple dormers or valleys, can take longer. Your written estimate includes a specific timeline.
Yes. Almost every homeowner stays home during the work. It is loud, especially during tear-off, and you should move vehicles out of the driveway and take fragile items off walls in upper rooms. Pets are usually happier somewhere quiet for the day.
Yes. We pull the permit with your town or city before work starts and handle the inspection at the end. Permit requirements vary between New Hampshire municipalities and the cost is listed as a line item on your estimate.
Not always, but it is often the right time. Gutters have to come off or be worked around during tear-off, so replacing worn gutters during a roof replacement costs less than doing it as a separate job later. We will tell you honestly whether yours have life left in them.
It covers our installation work: leaks or failures caused by how the roof was installed. It is separate from the manufacturer’s warranty on the shingles themselves, which covers material defects. You get both in writing, and we register the workmanship warranty before we leave the job.
