Skylight Installation and Replacement in Windham, NH
Windham’s roofs skew newer than a lot of the territory we work, mostly post-1980 colonials and raised ranches with steeper pitches and a fair number of cathedral-ceiling additions built over garages and family rooms. A good chunk of those homes came with a builder-grade acrylic dome skylight over the kitchen or a bath, and those units are now old enough that the seals are shot, the plastic has yellowed, and the homeowner is deciding whether to swap it for something better or open up a room that never had natural light to begin with.
Skylight Installation and Replacement in Windham
There are two different jobs under this one heading and they are not the same decision. The first is replacement: an existing skylight, usually the same builder-grade unit that’s been up there since the house was framed, gets pulled and swapped for something better while a reroof or a section of the roof is already opened up. This is the more common call we get, and it’s the cheaper one, because the labor to expose the curb and re-flash it is already priced into the roofing job.
The second is a new cut-in. A homeowner has a north-facing bedroom, a dark upstairs bath, or a stairwell that never gets light, and wants to open the roof deck where nothing existed before. That’s a bigger project, a bigger decision, and it needs framing work in the attic in addition to the roofing and flashing work on top. We’ll tell you honestly which category your job falls into and what it actually involves before you commit to anything.
Deck-mounted
units fasten straight to the roof deck and use a matched step-flashing kit. This is what goes on most pitched roofs now. It sits low, looks clean and handles snow well.
Curb-mounted
units sit on a raised wood frame built on the roof. They are the right call on low-slope sections, generally below about 3 in 12, and a lot of older installs already have them.
Fixed
units let in light and nothing else. Fine over a high cathedral ceiling you will never reach.
Manual or electric venting
units open to let heat and steam out. They earn their keep in kitchens and bathrooms.
Solar-powered venting
units run off a small panel, need no wiring to the house, and close on their own when the rain sensor gets wet.
What Windham roofs and homes are working with
A lot of Windham’s housing stock went up in the same building push as Derry, Londonderry, and Salem, NH did, which means a lot of original skylights across this whole corridor are hitting the same age at roughly the same time. If your neighbors are seeing fogged double-pane units or cracked acrylic domes, yours is probably close behind. That common build era is also why we see a lot of cathedral ceilings and finished second-floor rooms directly under the roof deck here, more than in the older, more compartmentalized homes closer to the Massachusetts line. That matters for skylight work because a cathedral ceiling means the light shaft is short or nonexistent, which simplifies a new cut-in considerably.
Tree cover is heavier on the lots backing up to conservation land and the areas around Cobbetts Pond, and that shade brings pine needles and moss into valleys and around skylight curbs, which shortens the life of the flashing and the shingles around the opening. On open, unshaded roofs we watch for ice dam buildup on north-facing slopes in the winter, which stresses skylight flashing more than almost anything else on the roof. Windham doesn’t carry the historic district restrictions you find in some Massachusetts towns, so visibility from the street generally isn’t a constraint here, but we still check pitch and roof complexity on every quote, because a simple gable roof and a roof with three or four intersecting planes are not the same labor.
How we assess it
Before we tell you what we’d recommend, we get on the roof and look at the actual condition around the unit. That means checking the flashing kit at the curb, the shingle course tying into it, and whether that flashing has been step-flashed correctly or just caulked over at some point by someone in a hurry. We check the roof deck itself where it meets the skylight opening, because soft or delaminated plywood there changes the scope of the job. Inside, we look at the underside of the skylight or the ceiling around it for staining, which tells us whether we’re dealing with a failed seal, a flashing leak, or condensation from poor attic ventilation.
We also look at ridge and soffit ventilation in the attic space near the unit, because a skylight installed in a poorly ventilated roof will sweat and stain the drywall no matter how good the unit itself is. All of this happens before we give you a recommendation, not after. If the fix is a $40 seal kit and not a new skylight, we’ll say so.
What the job involves
Replacement
We strip the shingles around the unit, pull the old skylight and flashing, repair the deck at the opening if it needs it, and set the new unit. Ice and water shield wraps up the sides and across the top, the step-flashing kit goes on, and we shingle back in. If the new unit matches the rough opening, the interior usually stays as it is. On a full roof replacement in Windham, all of this fits inside the reroof. The shingles are already off, the deck is exposed, and the new underlayment and flashing tie in as one system.
New cut-in
We lay out the opening from inside and out, cut the deck, and frame headers between the rafters. Ventilation gets rerouted so the bays above and below the opening still breathe. Then the unit, ice and water shield, flashing and shingles. Inside, a new opening means a light shaft through the attic, drywall and paint. That interior work is part of the conversation at the estimate, and we settle who handles what before anything is scheduled.
For a replacement, the work is straightforward if the existing opening and curb are sound: remove the old unit, inspect and repair the deck if needed, install new flashing, and set the new skylight to the existing curb or a new curb-mounted flashing kit. Curb-mounted units sit on a raised wood curb and are the standard for most residential retrofits. Deck-mounted units sit flush to the roof deck and give a lower profile look, but they’re less forgiving to install correctly and cost more in labor.
You’ve also got the fixed versus venting decision. Fixed units are simpler, cheaper, and have one less place to leak, since there’s no moving hardware or hinge seal. Venting skylights open manually or electronically and are worth it over a kitchen, bath, or any room that builds up humidity. Solar-powered venting units run on a small panel built into the unit itself, no wiring back to the electrical panel needed, and they’re a common upgrade during a reroof because the extra labor to run power isn’t there.
For a new cut-in, add framing work: cutting the roof deck, framing the rough opening between rafters, building the light shaft down through the attic or cathedral space, and coordinating the interior finish, drywall, and paint. We’ll walk that piece of it with you as part of the conversation, since it’s a separate trade from the roofing and flashing work we do.
What it costs
A straightforward replacement, same size unit, same curb, done while the roof is already open for a reroof, runs {PRICE_LOW} to {PRICE_HIGH} in most cases. That range moves with unit type: a basic fixed unit costs less than a venting model, and a solar-powered venting unit costs more than either. Curb-mounted replacements are generally cheaper than switching to a deck-mounted unit, and a steep or complicated roof with limited access adds labor regardless of the unit itself.
A new cut-in costs meaningfully more, because you’re paying for framing, a new roof penetration built from scratch, and often interior finish work on top of the roofing and flashing. If the deck around an existing opening has rotted from a long-term leak, that repair gets added to the scope too. The single biggest cost lever on this whole page: a skylight replaced while the roof is already open for a reroof costs a fraction of the same unit installed as its own standalone job later, because you’re not paying twice to open and reflash the same section of roof.
How long it takes
A single skylight replacement, when it’s paired with a reroof already underway, typically adds well under a day to the schedule since the roof is already exposed. Done as a standalone job on an existing curb, it’s usually a one-day project depending on access and pitch. A new cut-in takes longer, generally a few days between the framing, the roof work, and coordinating whatever interior finish is planned, and weather can push that if we’re mid-project when it turns.

If you’ve got a skylight in Windham that’s fogging, yellowing, or original to a house built in the 80s or 90s, or you’re staring at a dark room and thinking about cutting one in, call Couture’s Construction at {PHONE}. We work both sides of the Massachusetts and New Hampshire line out of Methuen, so a Windham address is nothing new to us. We’ll get on the roof, tell you what’s actually there, and give you a straight answer on replacement versus a new opening before anything gets scheduled.
Can you replace a skylight without doing a full reroof?
Yes. Standalone replacements are common, especially when the unit itself has failed but the rest of the roof still has years left. It costs more than doing it during a reroof since we're opening and reflashing that section on its own, but it's a routine job.
How do I know if my skylight needs to be replaced or just resealed?
Staining or a fogged double-pane usually means a failed seal, which can sometimes be fixed with new flashing or a seal kit rather than a full unit swap. We check this during the assessment before recommending anything, since a full replacement isn't always necessary.
Is a venting skylight worth the extra cost over a fixed unit?
Over a kitchen, bath, or any room that generates humidity, yes. Venting lets moist air escape instead of condensing on the glass and dripping down the shaft. Over a hallway or stairwell where humidity isn't an issue, a fixed unit is usually the better value.
Does Windham have permitting requirements for a new skylight cut-in?
New Hampshire towns handle roofing and skylight permits differently than Massachusetts towns do, and Windham has its own process separate from what we're used to across the border. We handle that as part of the job so you're not tracking it down yourself.
