You stop checking the ceiling every time a storm rolls through. No more buckets, no more stains spreading across your ceiling, no more wondering if this is the storm that finally does serious damage.
A properly replaced skylight means your home stays dry when it needs to. The glass doesn’t fog up because the seals actually work. Your energy bills stop climbing because cold air isn’t pouring in around the frame all winter.
You get natural light without the constant trade-off of water damage and drafts. That’s what a real skylight replacement does—it removes the problem entirely instead of just patching it for another season. Most homes in West Islip were built between 1940 and 1960, and if your skylight is original or even 15-20 years old, you’re past the point where repairs make sense. Replacement gives you decades of reliability, not months.
We work exclusively in Suffolk County, and we’ve seen what Long Island weather does to skylights. Freeze-thaw cycles crack seals, coastal humidity eats through flashing, and nor’easters test every weak point in your roof.
We don’t use subcontractors. Every person on your roof is trained by us, insured through us, and held to our standards. That matters when you’re dealing with something as critical as keeping water out of your home.
We’ve been handling skylight window replacement and roof skylight replacement across West Islip for years. We know the building codes, we work directly with insurance companies when storm damage is involved, and we pull the permits so you don’t have to. You’re hiring people who understand what it takes to make a skylight last in this climate.
We start with an inspection of your current skylight and the roof around it. Most leaks aren’t just the skylight—they’re the flashing, the seals, or the way it was originally installed. We need to see what’s failing before we can fix it right.
Once we know what you need, we walk you through your options. That includes the type of skylight that makes sense for your roof pitch, whether you want it vented or fixed, and what kind of glass works best for energy efficiency. We install Velux skylights because they’re engineered for climates like ours, and they come with warranties that actually mean something.
During installation, we remove the old skylight and inspect the roof deck for any water damage or rot. If there’s an issue, we handle it before the new skylight goes in. Then we install the new unit with integrated flashing, multiple waterproof barriers, and proper sealing at every layer. The skylight gets tested before we leave, and you get a leak-free guarantee in writing.
The whole process typically takes one day for a standard replacement. If there’s underlying damage or you’re upgrading to a larger unit, it might take two.
Ready to get started?
Every skylight replacement includes removal of your old unit, disposal of all materials, and a full inspection of the roof structure underneath. If we find rot or damage, we let you know before moving forward—no surprises halfway through the job.
You get a new Velux skylight with integrated flashing designed specifically for your roof type. Flat roofs get curb-mounted systems with multiple waterproof membrane layers. Pitched roofs get step flashing and continuous flashing sealed with high-grade materials that hold up to Suffolk County winters.
We handle the permit process with the town of Islip. We coordinate with your insurance company if the damage is storm-related. And if you want upgraded features like solar-powered operation or rain sensors that automatically close your skylight when it starts pouring, we install those too.
West Islip homes face specific challenges—coastal humidity accelerates material breakdown, and freeze-thaw cycles are brutal on any weak points in your roof. That’s why we don’t cut corners on flashing or sealing. The average skylight replacement cost in 2025 runs between $2,000 and $5,300 depending on size and features, but that investment gets you 20+ years of performance when it’s done right.
If your skylight is leaking in multiple spots, showing condensation between the glass panes, or more than 15 years old, replacement makes more sense than repair. Here’s why: three out of four skylight leaks come from the skylight itself, not the flashing. That means the seals have failed, the frame has degraded, or the glass unit has lost its integrity.
Repairs work when the skylight is relatively new and the problem is isolated—a small flashing issue or a single cracked seal. But if you’ve already repaired it once and it’s leaking again, you’re chasing symptoms instead of fixing the root cause. Skylights in West Islip take a beating from freeze-thaw cycles and coastal weather. Once the seals start failing, it’s a countdown until the next leak.
Replacement also makes sense if you’re seeing higher energy bills, drafts around the skylight, or visible light coming through gaps in the frame. Modern skylights are significantly more energy efficient than units installed even 10 years ago. The upfront cost of replacement pays for itself in lower heating and cooling bills, plus you eliminate the ongoing maintenance costs of a failing unit.
Velux skylights are engineered specifically for climates with harsh winters and high humidity—exactly what we deal with on Long Island. They use integrated flashing systems that work with your roof’s water management instead of fighting against it. That’s critical in areas like West Islip where storms and freeze-thaw cycles test every weak point.
The difference between brands comes down to how they handle water, how well they insulate, and how long the materials last. Cheaper skylights use separate flashing that relies on sealant to keep water out. Sealant degrades. Velux uses a flashing system that overlaps and channels water away from the opening, so even if one layer has an issue, you’ve got backup protection.
Velux also offers real warranties—on the glass, the flashing, and the operating mechanisms if you go with a vented unit. Their solar-powered models include rain sensors that automatically close the skylight when it starts raining, which is a lifesaver if you’re not home when a storm hits. We’ve installed hundreds of skylights across Suffolk County, and Velux units consistently outlast and outperform other brands. That’s why we use them—not because of markup, but because we don’t want to come back in five years to fix someone else’s design flaws.
A standard residential skylight replacement takes one full day from start to finish. We show up in the morning, remove your old skylight, inspect the roof deck and framing, install the new unit with proper flashing and sealing, and test everything before we leave. You’ll have a functional, watertight skylight by the end of the day.
If we find rot or structural damage when we remove the old skylight, that adds time. We’re not moving forward until the roof deck is solid and properly sealed. That might mean an extra half day or full day depending on the extent of the damage, but it’s not optional—you can’t install a new skylight over compromised structure and expect it to last.
Weather can also affect timing. We’re not installing skylights in the rain or when there’s ice on the roof. If conditions aren’t safe, we reschedule. During installation, your home is open to the elements for a few hours while we’re working, but we tarp and secure everything if we need to pause for any reason. Most homeowners are surprised by how quick and clean the process is compared to what they expected. We handle all the cleanup and disposal, so you’re not left with debris or old materials sitting in your driveway.
It depends on what caused the damage and what your policy covers. If a storm cracked your skylight or tore up the flashing, that’s typically covered under wind and hail damage. If your skylight is leaking because it’s old and the seals have worn out over time, that’s considered maintenance and usually isn’t covered.
Insurance companies want documentation. That means photos of the damage, a detailed estimate that separates storm damage from pre-existing wear, and sometimes an adjuster visit. We work directly with insurance companies and we know what they need to approve a claim. We document everything, provide itemized estimates, and communicate with adjusters so you’re not stuck playing middleman.
One thing to watch for: some policies will only cover the cost to repair, not replace. If your skylight can technically be repaired but replacement makes more sense long-term, you might have to cover the difference. We’ll walk you through what’s covered and what’s not before any work starts, so there’s no confusion about who’s paying for what. We’ve helped dozens of West Islip homeowners navigate claims after nor’easters and hurricanes. The process isn’t fun, but having someone who knows how to handle it makes a big difference.
It shouldn’t, and if it does, we come back and fix it at no cost to you. Every skylight replacement we do includes a leak-free guarantee on our workmanship. That covers the installation, the flashing, and the sealing—basically everything we control during the job.
Leaks after installation are rare when the work is done right, but they can happen if something shifts during settling or if there’s an issue we couldn’t see until the skylight was under load. The difference between us and other contractors is we don’t argue about whose fault it is. If water is coming in around a skylight we installed, we take responsibility and we fix it.
The Velux skylight itself also comes with a manufacturer warranty that covers defects in materials and operation. If the glass unit fails, the flashing cracks, or the opening mechanism breaks, that’s on Velux and they’ll replace it. We handle the coordination with them so you’re not dealing with customer service calls and shipping delays. You call us, we assess what’s wrong, and we handle it. That’s what a real warranty looks like—not fine print that makes it impossible to actually get help when you need it.
Yes, and flat roofs actually require a different installation approach than pitched roofs. Flat roof skylights need curb-mounted systems, which means we build or install a raised curb that lifts the skylight above the roof surface. This allows water to drain away from the skylight instead of pooling around it, which is critical on a flat or low-slope roof.
The flashing on a flat roof skylight uses multiple waterproof membrane layers that tie into your existing roof membrane. It’s more involved than a pitched roof installation, and it requires someone who understands how flat roofs manage water. We’ve handled plenty of flat roof skylight replacements across West Islip, and the key is making sure the curb is properly flashed and sealed at every transition point.
Cathedral ceilings add a different challenge—access. If your skylight is 20 feet up and there’s no attic space to work from, we’re doing everything from the exterior. That’s fine, but it means the installation takes a bit longer and requires more staging and safety equipment. The skylight itself installs the same way, but getting to it and sealing the interior finish requires more coordination. We’ve done enough of these to know what works and what doesn’t. If your home has either situation, we’ll walk you through what’s involved during the estimate so you know exactly what to expect.
