You stop worrying about the next rainstorm. No more buckets, no more stains spreading across your ceiling, no more wondering if this winter’s going to make it worse.
Your energy bills drop because modern skylight window replacement means real insulation—not the single-pane units from 20 years ago that leak heat in January and turn your upstairs into a sauna in July. You’re looking at double or triple-pane glass with low-E coatings that actually work.
And you’re done throwing money at temporary fixes. A proper home skylight replacement in Islip Terrace means flashing that’s installed for Suffolk County’s freeze-thaw cycles, seals that handle salt air, and materials built to last through nor’easters. You get a leak-free guarantee and a warranty that covers both the product and the installation—because when it’s done right the first time, it stays right.
We’ve spent over a decade handling roof skylight replacement across Suffolk County. We’re licensed, insured, and we live here—so we know exactly what Islip Terrace weather does to skylights over time.
Most leak problems we see aren’t from bad skylights. They’re from bad installations. Flashing that wasn’t designed for coastal conditions. Sealants that crack after one winter. Shortcuts that save someone 20 minutes but cost you thousands in water damage.
We use Velux products because they’re built to last, and we install them the way they’re supposed to be installed—with multiple waterproof barriers, integrated flashing systems, and attention to the details that matter when you’re 10 miles from the Atlantic. You’re not getting the cheapest option. You’re getting the one that works.
We start with an honest assessment. If your skylight can be repaired, we’ll tell you. If it’s 15+ years old and showing signs of seal failure, we’ll explain why replacement makes more sense than patching it again.
Once you decide to move forward, we handle everything. We remove the old unit carefully to avoid damaging your roof deck or interior. Then we inspect the framing and decking for any rot or damage that needs addressing before the new skylight goes in—because covering up a problem doesn’t fix it.
The new Velux skylight gets installed with proper flashing designed specifically for your roof pitch and material. We’re talking about multiple layers of waterproofing, not just slapping some tar around the edges. The interior gets finished clean, and we walk you through the warranty coverage for both materials and labor.
You’re looking at a day or two for most residential skylight replacement jobs in Islip Terrace, depending on how many units you’re replacing and what we find when we open things up. And you get 18-month interest-free financing if that makes the timing work better for you.

You get premium Velux skylights with up to 10-year manufacturer warranties. These aren’t builder-grade units—they’re insulated glass designed for energy efficiency and impact resistance. You’re choosing from fixed, vented, or solar-powered options depending on what works for your space.
The installation includes complete removal of your old skylight, inspection and repair of any underlying damage, and professional installation with flashing systems built for Suffolk County’s climate. That means handling salt air corrosion, freeze-thaw cycles, and the kind of wind-driven rain that comes off the Atlantic during a nor’easter.
In Islip Terrace, most homes we work on have skylights that are 15 to 25 years old. The seals fail, the flashing corrodes, and the single-pane glass wastes energy. You’re not just getting a new skylight—you’re getting modern materials that cut your heating and cooling costs and a proper installation that stops the leaks for good. Interior finishing is included, so you’re not left with exposed drywall or trim work to figure out on your own.
Most skylight replacement projects in Islip Terrace run between $2,000 and $5,300 per unit, depending on size, type, and what we find when we open up the roof. That includes the Velux skylight itself, complete removal of the old unit, proper flashing installation, and interior finishing.
If there’s rot in the framing or decking—which is common with skylights that have been leaking for a while—that adds to the cost because we have to repair the structure before installing the new unit. But you’ll know about that upfront, not after we’ve already started tearing things apart.
The price difference usually comes down to whether you’re going with a fixed skylight, a manual venting model, or a solar-powered unit with remote controls. Bigger skylights cost more, and if your roof pitch is steep or the access is difficult, that factors in too. We give you an upfront price after we look at your specific situation—no surprises, no “we’ll figure it out as we go.”
If your skylight is under 10 years old and the leak is coming from damaged flashing or a broken seal that can be fixed, repair makes sense. If it’s 15+ years old, you’re probably throwing money at a temporary fix.
Here’s why: skylights in Suffolk County take a beating from salt air, freeze-thaw cycles, and coastal storms. The seals break down, the glass loses its insulating properties, and the flashing corrodes. You can patch it, but you’re likely looking at another leak in a year or two—and in the meantime, you’re losing heat in winter and paying more to cool your house in summer.
Replacement gives you modern insulated glass, proper flashing designed for Long Island’s climate, and a warranty that covers both the product and the installation. You stop dealing with recurring problems and you start saving on energy costs. Most homeowners who’ve been patching the same skylight for years wish they’d replaced it sooner.
Most single skylight replacements take one full day, sometimes stretching into a second day depending on what we find and how much interior finishing is involved. If you’re replacing multiple units, add another day or two.
The actual removal and installation of the skylight itself isn’t what takes time—it’s doing it right. We’re inspecting the roof deck and framing, repairing any rot or damage, installing multiple layers of waterproofing, and making sure the flashing integrates properly with your roofing material. Then there’s interior work: drywall, trim, paint touch-ups.
Weather can delay things because we’re not installing a skylight in the rain or when there’s ice on your roof. We’ll work with you on timing, and we’ll protect your home with tarps if we need to leave the opening covered overnight. You’ll know the timeline before we start, and we’ll keep you updated if anything changes.
Yes, if you’re replacing an old single-pane unit with modern insulated glass. You’re looking at potential savings of 10-15% on heating and cooling costs for the rooms with skylights—sometimes more if your current skylights are really inefficient.
Old skylights are basically holes in your roof when it comes to energy loss. Single-pane glass does almost nothing to stop heat transfer. In winter, warm air escapes. In summer, heat pours in. Modern Velux skylights use double or triple-pane glass with low-E coatings that reflect heat back into your house when it’s cold and keep it out when it’s hot.
The payback period varies depending on your energy costs and how many skylights you’re replacing, but most homeowners in Islip Terrace notice the difference in their first winter. Your upstairs doesn’t feel like a freezer in January, and your AC isn’t running constantly in July trying to compensate for heat gain through the roof.
Yes. You get a manufacturer’s warranty on the Velux skylight itself—typically 10 years on materials—and our workmanship warranty on the installation. If there’s a leak related to how we installed it, we come back and fix it at no charge.
The manufacturer’s warranty covers defects in the skylight: glass seal failure, frame issues, hardware problems. Our installation warranty covers flashing, waterproofing, and anything related to how the unit was integrated into your roof. Both warranties are transferable if you sell your home, which helps with resale value.
What the warranties don’t cover: damage from falling branches, hail, or other external impacts. They also don’t cover leaks caused by someone else working on your roof later and damaging the flashing. But for normal wear and tear, material defects, and installation issues, you’re protected. We stand behind our work because we do it right the first time.
Suffolk County’s coastal climate is brutal on skylights. You’ve got salt air corroding metal flashing, freeze-thaw cycles breaking seals, and wind-driven rain from nor’easters that finds every weak point in the waterproofing.
Salt air is the big one most people don’t think about. It starts corroding flashing and metal components from day one, and after 15 years, you’ve got rust and deterioration that creates leak paths. Then winter hits: water gets into small cracks, freezes, expands, and turns those cracks into bigger openings. Do that for 20 winters and even a well-installed skylight starts failing.
Add in the fact that many skylights in Islip Terrace were installed during the building boom with whatever flashing was cheapest and fastest, not what actually works long-term in coastal conditions. That’s why we use flashing systems designed specifically for this environment and why we don’t cut corners on waterproofing. Your skylight needs to handle what Long Island throws at it—not what works fine in Arizona.
