Siding Installation & Replacement in New Hampshire
Siding is the part of your house that takes the weather every day of the year. We install vinyl and fiber cement with the weather barrier and flashing detail that actually keeps water out of the wall.
What We Do
Siding That Protects, Not Just Covers
Most people think of siding as the appearance of the house. It is really the outer layer of a water management system, and the parts that decide whether it works are the ones you cannot see once the job is finished.
Vincenzo’s Roofing installs and replaces siding on residential and commercial properties across New Hampshire from our base in Seabrook. We remove the old siding rather than covering it, because covering hides rotted sheathing and traps moisture in the wall where it does the most damage.
Coming at siding from roofing gives us a particular advantage at the junction where the wall meets the roof. That transition, along with the flashing around windows and doors, is where the large majority of siding related water damage begins. It is also the detail most commonly rushed.
Assessment
Signs Your Siding Needs Replacing
One or two of these may only need a repair. Several together usually mean the wall behind is already taking on water.
Cracked or broken panels
Any break in the surface is a direct route for water into the sheathing. Cold makes older vinyl brittle and prone to splitting.
Warping or buckling
Panels pulling away or rippling usually means moisture behind the siding or an installation that left no room for movement.
Soft spots in the wall
If the wall gives when pressed, the sheathing underneath has already rotted. This one needs attention quickly.
Peeling paint indoors
Bubbling paint or wallpaper on interior walls often means moisture is passing through the exterior wall assembly.
Mould, mildew, or fungus
Growth along seams and at the base of walls is a sign that water is sitting where it should be draining away.
Rising heating bills
Failed siding lets wind reach the sheathing and wet insulation loses most of its value. Costs climb before anything looks obviously wrong.
Materials
Choosing Your Siding Material
Three materials cover almost every siding job in New Hampshire. The right one depends on your budget, how long you plan to stay, and how exposed the house is.
Most popular
Vinyl siding
Lightweight PVC panels in a wide colour range
- Lowest installed cost of the main options
- Never needs painting, colour runs through the panel
- Insulated backing available for better thermal performance
- Fastest installation, which keeps labour costs down
Premium
Fiber cement
Dense cement and cellulose board with a wood grain finish
- Very close match to real wood in appearance
- Fire resistant and highly impact resistant
- Holds paint for 10 to 15 years between recoats
- Excellent choice for coastal and exposed properties
Middle ground
Engineered wood
Treated wood strand board with a factory finish
- Authentic wood texture at less than fiber cement cost
- Lighter than fiber cement, so faster to install
- Comes pre primed or fully factory finished
- Needs repainting sooner than fiber cement does
What about cedar and natural wood?
Cedar shingles and clapboard remain beautiful on New England homes and are sometimes required by historic district guidelines. They also demand real ongoing maintenance, particularly near the coast, where salt and moisture accelerate weathering. We will happily quote cedar, and we will be straightforward with you about the upkeep it needs.
Under the Surface
What Sits Behind Your Siding
Siding is the visible layer of a system with several parts. When a wall fails it is almost never the panel that caused it, so this is what we install and inspect on every job.
The structural board fixed to the framing. We inspect all of it once the old siding is off and replace anything soft, delaminated, or rotted before going further.
The weather resistant barrier that sheds any water getting past the siding while still letting the wall breathe. Overlapped and taped correctly, or it does nothing.
Metal detailing at windows, doors, and the roof to wall junction. This is where most water actually enters a wall, and where corners get cut most often.
Corner posts, J channel, and the starter strip that sets the line for every panel above it. Get the first course wrong and the whole wall follows it.
Fastened with room to expand and contract through a New Hampshire year. Nailed too tight and panels buckle in July or crack in January.

Straight Pricing
How Much Does Siding Cost in New Hampshire?
Vinyl on an average home sits toward the lower end of that range, and fiber cement on a larger house with significant trim work sits at the top. We would rather you see the spread now than sit through a sales visit to reach it. You get an itemized written estimate after an on site measure.
- Wall area total square footage plus the number of storeys
- Material vinyl, engineered wood, or fiber cement
- Sheathing condition rot found once the old siding is off
- Trim and detail gables, bays, dormers, and window count
- Insulation whether insulated backing is added
- Access tight lots and steep ground affect staging time
How It Works
Your Siding Project, Step by Step
Free measure
We measure the walls, check the current siding and trim, and look for any signs of moisture already in the assembly.
Material and colour
You choose material, profile, and colour. We bring samples so you can see them against your house rather than on a screen.
Written estimate
Itemized pricing covering materials, labour, trim, disposal, and a realistic timeline for your specific home.
Strip and inspect
Old siding comes off one elevation at a time. Sheathing is inspected, repairs made, then wrap and flashing go on.
Install and finish
Panels and trim installed, site cleared, then a walkthrough with you before the warranty is registered.
Worth Considering
Doing Your Roof and Siding Together
Why it often makes sense
The junction where the roof meets the wall is responsible for a large share of the leaks we get called out to. Detailing that transition correctly is far easier when both surfaces are open at the same time. You also get one schedule, one crew, one disruption, and a single point of responsibility if anything ever needs revisiting.
When to keep them separate
If one of the two has real service life left, there is no sense replacing it early just for convenience. We will tell you honestly if your roof has eight good years in it, even though combining the work would be the larger job for us.
Local Expertise
What New Hampshire Does to Siding
The same panel behaves very differently in Seabrook than it does inland. These are the details we adjust by location.
Salt air on the Seacoast
Salt corrodes standard nails and flashing well before the siding itself is worn out. On coastal jobs we specify stainless or coated fixings and corrosion resistant flashing as standard, not as an extra.
Wind driven rain
A nor’easter pushes water sideways and upward, finding gaps that ordinary rainfall never reaches. Correct overlap on the house wrap and properly lapped flashing matter far more here than in a sheltered climate.
Freeze and thaw movement
Vinyl expands and contracts measurably between a January night and an August afternoon. Fastened without room to move, panels buckle in summer and crack in winter. Nailing technique decides this.
Snow sitting against walls
Drifted snow banked against the base of a wall keeps it wet for weeks. Proper clearance at grade and a correctly installed starter strip stop that moisture wicking up behind the siding.
FAQ
Siding Questions
Most siding projects in New Hampshire fall between 9,000 and 40,000 dollars. Vinyl on an average home sits toward the lower end, while fiber cement on a larger house sits at the upper end. The variables are the size of the wall area, the material you choose, how much trim and detail work the house has, and whether any sheathing underneath has rotted and needs replacing.
Quality vinyl siding lasts roughly 25 to 40 years here. Fiber cement typically reaches 30 to 50 years, and engineered wood around 20 to 30 years. Coastal properties sit at the lower end of each range because salt air is hard on fasteners and finishes. Installation quality and the condition of the weather barrier behind the siding matter as much as the material itself.
Vinyl is a lightweight plastic panel that costs less, installs faster, and never needs painting. Fiber cement is a dense composite of cement and cellulose that is heavier, more impact resistant, fire resistant, and holds paint for many years. Fiber cement costs roughly double vinyl installed and gives a closer match to real wood, which is why it is common on higher value and historic homes.
It is sometimes done, but we do not recommend it. Covering old siding hides any rot, mould, or water damage in the sheathing underneath, prevents proper installation of the weather barrier, and can trap moisture inside the wall. We remove the existing siding so the sheathing can be inspected and the house wrap and flashing installed correctly.
Most residential siding projects in New Hampshire take one to two weeks. A modest home in vinyl can be finished in under a week, while a larger house in fiber cement with significant trim detail takes longer. Weather is the main variable, and your written estimate includes a realistic timeline for your specific home.
If both are near the end of their service life, doing them together is usually the better decision. The junction where the roof meets the wall is where a great many leaks begin, and detailing that transition properly is far easier when both surfaces are open at once. It also means one set of crews, one schedule, and one disruption instead of two.
Late spring through autumn is ideal, with mild temperatures and stable weather. Vinyl becomes brittle in deep cold and expands noticeably in heat, so installers allow for movement accordingly. We do install siding in winter when circumstances require it, working in sections so the house is never left exposed overnight.
