Your skylight stops leaking. That’s the baseline.
But here’s what else changes: your heating bill drops because you’re not pumping warm air through gaps in old seals. Your ceiling stays dry through March snowmelt and August thunderstorms. You stop worrying every time the forecast calls for heavy rain.
Modern skylight window replacement means double-pane glass with Low-E coatings that block heat in summer and trap it in winter. It means flashing systems that account for Long Island’s freeze-thaw cycles, not just generic installation specs. Vented models let humid air escape instead of condensing on your windows and walls.
You’re not just fixing a leak. You’re upgrading to a skylight that handles what Centerport weather throws at it—nor’easters, ice dams, salt air, and the kind of temperature swings that crack old seals and warp cheap frames.
The difference shows up in your energy bills, your comfort, and the fact that you’re not calling someone back out here in two years.
We’ve spent 10+ years working on homes across Suffolk County. We’re licensed, insured, and local—meaning we understand how coastal weather beats up roofs and skylights differently than inland climates.
Centerport homeowners deal with specific problems: salt air corrosion, heavy snow loads, and humidity that most contractors don’t account for unless they’ve worked here. We’ve replaced hundreds of skylights on Long Island, and we know which products hold up and which ones fail early.
Our crews live here. We’re not driving in from out of state, and we’re not disappearing after the job. When we install a skylight, we’re standing behind it in the same community where we raise our families and run our business.
You’ll get transparent pricing before we start, a clear timeline, and work that’s done right the first time.
We start with an inspection of your current skylight—checking the frame, flashing, seals, and surrounding roof structure. Most leaks aren’t just the glass. They’re failed flashing or deteriorated seals that let water work its way under shingles.
Once we know what’s causing the problem, we give you an upfront estimate that includes the skylight unit, all materials, labor, and any roof repairs needed to do the job correctly. No surprises.
On install day, we remove the old skylight and inspect the roof deck for any water damage or rot. If we find issues, we fix them before the new unit goes in. Then we install the new skylight with integrated flashing, multiple waterproof barriers, and sealants rated for Long Island’s temperature swings.
We test everything before we leave. That means running water over the flashing, checking the seals, and making sure the unit operates smoothly if it’s vented. You’re not waiting to see if it leaks during the next storm—we verify it’s watertight before we pack up.

Every roof skylight replacement includes removal of your old unit, disposal, and a full inspection of the roof deck and surrounding structure. If there’s rot or damage from years of leaking, we repair it as part of the job.
We install Velux skylights—the brand that’s built for harsh climates and actually backs their products with real warranties. You’re getting double-pane, Low-E glass that cuts UV rays and regulates temperature. Frames are designed to handle expansion and contraction without cracking seals.
Flashing is custom-fit to your roof pitch and skylight size. We’re not using generic kits that leave gaps. Every seam gets sealed with materials rated for freeze-thaw cycles, and we integrate the flashing with your existing shingles so water sheds properly.
In Centerport, where homes average 65+ years old, we also check your attic insulation and ventilation. A skylight won’t perform right if your attic is trapping heat and moisture. If we see issues, we’ll flag them so you can address them now or later—but you’ll know what’s going on.
You’re also getting a leak-free guarantee. If water gets in because of our installation, we come back and fix it at no cost.
Most residential skylight replacements take four to six hours per unit, depending on roof access, pitch, and whether we’re repairing underlying damage. If your roof deck has rot or your flashing needs custom fabrication, it might stretch into a full day.
We don’t rush the flashing. That’s where most skylight leaks start, and it’s the part that gets skipped or done poorly when crews are trying to move fast. We take the time to integrate it correctly with your shingles and seal every seam.
Weather can delay things. We won’t install a skylight in the rain or when ice is on the roof. If conditions aren’t right, we’ll reschedule rather than risk a bad install that leaks later.
Skylight replacement typically runs between $1,200 and $2,800 per unit, including labor and materials. That price covers removal of the old skylight, a new Velux unit with flashing, installation, sealing, and cleanup.
The range depends on skylight size, roof pitch, and whether we’re fixing underlying damage. A straightforward swap on an accessible roof costs less than a steep-pitch install where we’re also replacing rotted decking. Vented or solar-powered models cost more than fixed units.
We give you a clear estimate before starting. You’ll know exactly what you’re paying for—the skylight, the labor, the materials, and any repairs. If we find additional damage during the job, we’ll discuss it with you before proceeding.
Insurance sometimes covers skylight replacement if the damage came from a storm. We can work with your adjuster and provide documentation if you’re filing a claim.
Yes, if it’s installed correctly with proper flashing and seals designed for freeze-thaw cycles. Most skylight leaks aren’t the glass—they’re failed flashing or deteriorated seals that let water seep under shingles.
Long Island weather is hard on skylights. Nor’easters dump heavy rain sideways. Snow melts, refreezes, and creates ice dams. Coastal humidity accelerates seal degradation. A skylight installed with generic flashing or cheap sealants will fail within a few years.
We use integrated flashing systems that match your roof pitch and skylight dimensions. Every seam is sealed with materials rated for temperature swings and UV exposure. We also install multiple waterproof barriers so even if water gets past the first line of defense, it’s redirected away from your ceiling.
You’re getting a leak-free guarantee. If water gets in because of our installation, we come back and fix it at no cost. We’ve been doing this for over a decade on Long Island, and we know what holds up.
If your skylight is over 15 years old, replacement is usually the better move. Seals degrade, frames warp, and glass coatings break down. You can patch a leak temporarily, but you’re likely to be calling someone back out in a year or two.
Repairs make sense if the skylight is newer and the leak is isolated—like a small gap in the flashing that can be resealed. But if you’re seeing water stains, condensation between panes, or drafts, the unit is failing and repairs won’t fix the underlying problem.
Older skylights also cost you money. Single-pane glass and outdated seals let heat escape in winter and pour in during summer. Your HVAC system works harder, and your energy bills reflect it. A new skylight with Low-E glass and proper insulation pays for itself over time through lower heating and cooling costs.
We’ll inspect your skylight and give you an honest assessment. If a repair will hold, we’ll tell you. If replacement is the smarter call, we’ll explain why and show you what’s failing.
Yes, as long as the roof isn’t covered in ice or snow and temperatures are above freezing during installation. Sealants and adhesives need specific temperature ranges to cure properly, and we won’t compromise the install by working in conditions that prevent materials from bonding correctly.
Winter replacement actually has advantages. Contractors are less busy, so scheduling is easier and labor rates can be lower. If your skylight is leaking now, waiting until spring means months of water damage, higher heating bills, and the risk of mold growing in your ceiling or attic.
We take extra precautions in cold weather. We tarp the opening if we need to leave the site overnight. We use cold-weather sealants rated for lower temperatures. We monitor the forecast and won’t start a job if a storm is moving in.
Late fall and early winter are often ideal for skylight replacement in Suffolk County. The roof is dry, temperatures are manageable, and you’re fixing the problem before the heavy snow and ice arrive in January and February.
Yes. Velux is what we install for most residential skylight replacements because they’re built for climates like Long Island’s and they back their products with real warranties.
Velux skylights come with double-pane, Low-E glass that blocks UV rays and regulates temperature. Frames are engineered to handle expansion and contraction without cracking seals. Flashing kits are designed to integrate with different roof types and pitches, which matters when you’re working on homes built in the 1950s and 60s with varying roof structures.
They also offer vented models with rain sensors—useful in Centerport’s humid summers when you want airflow but don’t want to worry about closing the skylight before a thunderstorm rolls in. Solar-powered options are available if you want remote operation without running electrical.
We’ve installed hundreds of Velux units across Suffolk County. We know how they perform in coastal weather, and we’ve seen which models hold up long-term. If you want a different brand or have a specific product in mind, we can work with that—but Velux is what we recommend for quality and longevity.
