Skylight Installation and Replacement in North North Andover, MA
North North Andover has two very different housing stocks sitting a few miles apart, and it shows up in the skylight calls we get. Out toward the Boxford line and around the Lake Cochichewick estates, you’ve got colonials and capes from the 80s and 90s with cathedral ceilings over the family room and a skylight or two that’s original to the build. Closer to Route 125 and the older village center, the housing runs older and lower-pitched, with fewer skylights to begin with and more homeowners asking about cutting one in for the first time.
Skylight Installation and Replacement in North North Andover
There are two jobs on this page and they’re not the same decision. The first is replacement: you already have a skylight, it’s original to the house or close to it, and it’s either fogged up, leaking around the flashing, or just old enough that you don’t trust it anymore. If you’re already having the roof done, swapping the skylight while the old shingles are off is the cheapest this job will ever be.
The second is a new cut-in. Nobody’s replacing anything, you’re opening a roof that’s never had a skylight and adding light to a room that doesn’t get any, usually a north-facing kitchen, a dark upstairs bath, or a stairwell. That’s a bigger job with more decisions attached, and it deserves a real look before anyone gives you a number.
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 North North Andover roofs and homes are working with
North North Andover’s housing spans a lot more ground than people expect for a town this size. The subdivisions built out through the 90s and early 2000s, especially in the newer developments off Sutton and Salem Street, are all approaching the same twenty to twenty-five year mark on their original architectural shingles and their original skylights at the same time. When we replace a roof on one of these houses, the skylight is usually part of the same conversation, because the unit is the same age as the shingles around it and it’s due.
Then there’s the older housing closer to the town center and down toward Lawrence, more of it two-story with lower-pitched additions and less finished attic space. Cathedral ceilings are less common there, so a skylight is more likely to run through unfinished attic space before it reaches a light shaft, which changes the framing work involved. Tree cover matters here too. A lot of North North Andover lots back up to wooded conservation land, and a skylight shaded most of the day behind oak and pine holds moisture and debris differently than one that sits in open sun, which affects both flashing wear and how much daylight you actually gain by cutting one in. North North Andover doesn’t carry the historic district restrictions you see in some neighboring towns, but if your house sits in one of the older established sections, it’s worth checking before you plan anything visible from the street.
How we assess it
Before we recommend anything, Derek or one of the crew leads gets on the roof and looks at what’s actually there. On a replacement, that means pulling back the shingle course around the curb to check the flashing, looking at the condition of the curb or deck framing itself, and getting into the attic to check the underside of the unit for staining, rot, or daylight where there shouldn’t be any. A skylight that’s been leaking slowly for a few years can take the decking around it down with it, and you want to know that before a price gets written, not after.
On a new cut-in, the assessment is about the framing more than the surface. We’re looking at rafter spacing, roof pitch, what’s directly below the proposed opening, and whether the run to a light shaft is straightforward or complicated by ductwork, wiring, or a load-bearing wall in the wrong spot. We’ll also check attic ventilation, because a poorly vented attic and a new skylight opening is a combination that causes problems later. None of this is guesswork. We tell you what we see and what it means before we tell you what it costs.
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 North Andover, 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.
Replacement starts with removing the old unit and the flashing kit around it, checking the deck for soft spots or water staining, and installing the new skylight with fresh step and counter flashing, not just a bead of sealant over the old kit. If ice dam history is a concern on that slope, we run ice and water shield up the sides and above the curb before the new flashing goes on. Curb-mounted units sit on a raised wood curb built up from the roof deck. Deck-mounted units sit lower, closer to the roofline, and have become the more common choice on newer builds because they’re less visible and shed water more cleanly. Which one you have already dictates a lot of the replacement work.
A new cut-in starts in the attic. We locate the rafters, confirm the opening size against the rafter bay, and frame the header and trimmers before anything gets cut from the outside. Once the hole is open, the unit goes in with proper flashing, and the roofing gets tied back in around it to match the existing field. From there, the interior side needs a light shaft built down to the ceiling and drywall and paint to finish it off. That interior work is part of the conversation when we scope the job, and we’ll tell you plainly what’s involved, but we’ll be upfront about what falls inside our roofing scope versus what you may need a finish carpenter or painter for.
What it costs
Replacement runs {PRICE_LOW} to {PRICE_HIGH} in most cases, and the biggest swing factor is whether the roof is already open for a reroof. Doing the skylight at the same time saves you a full re-flash and a separate mobilization, and it’s a fraction of the cost of calling us back out six months later to do the same unit on its own. Unit type matters too. A basic fixed skylight costs less than a manual venting unit, and a solar-powered venting skylight with a remote-operated shade costs more than either.
A new cut-in runs well above a straight replacement because you’re paying for framing, flashing a hole that’s never existed before, and often a light shaft and interior finish work on top of the roofing itself. Roof pitch and access affect labor time, and if the decking around the new opening turns out to be compromised once we’re into it, that’s additional. We’ll walk you through what’s driving the number before we hand you one, not after.
How long it takes
A straight replacement, especially one done alongside a reroof, is usually a same-day addition to that project. Done on its own, it’s typically a one-day job for one skylight, weather permitting. A new cut-in takes longer, usually one to three days depending on framing complexity and whether interior finish work is part of the scope, plus separate time if a painter or drywall contractor is finishing the light shaft. We’ll give you a real schedule once we’ve seen the roof and the room it opens into.
Skylight Questions from North North Andover Homeowners
Homeowners across North North Andover often ask about leaks, condensation, and whether an older skylight can simply be replaced without altering the surrounding roofline. Others want to know if a new skylight will actually cut down on energy costs during the region’s cold winters and humid summers.
- Will installation damage my ceiling or attic insulation?
- Can you match my existing roof pitch and materials?
- Do you handle both flat and pitched roof skylights?

Should I replace my skylight now or wait until I reroof?
If your roof has more than a few years of life left but the skylight is failing, replace it now rather than let a slow leak damage the decking around it. If a reroof is coming up in the next year or two, it's worth waiting and doing both together, since the labor overlap brings the cost down significantly.
Can I add a skylight to a room that doesn't have one now?
In most cases yes, but it depends on your rafter spacing, what's below the proposed opening, and your attic ventilation. That's exactly what the assessment is for. We'll tell you if the room is a good candidate before you commit to anything.
What's the difference between curb-mounted and deck-mounted skylights?
Curb-mounted units sit on a raised wooden curb built above the roof deck, which was the standard for decades. Deck-mounted units sit lower and closer to the roofline, ship with a factory-integrated flashing kit, and are the more common choice on newer installs. Which one you need for a replacement depends on what's already framed into your roof.
Do you handle leaking skylights too?
Leak repair and flashing waterproofing is a different job from installation or replacement. If your existing skylight is leaking and you're not sure yet whether it needs a new unit or just a re-flash, our skylight repair and waterproofing page in North North Andover covers that side of it.
