You’ll have a skylight that doesn’t leak when it rains. Your rooms stay bright without the drafts, condensation, or that nagging worry every time a storm rolls through. Energy bills drop because modern Velux skylights are up to 35% more efficient than the older plastic units most Southold homes still have.
Your attic stays dry. No more water stains spreading across your ceiling or that musty smell that shows up after heavy snow. The flashing is installed correctly this time, sealed against the freeze-thaw cycles that crack cheaper installations every winter.
You’re not patching the same problem twice. Most skylight leaks aren’t actually the skylight—they’re failed flashing or improper sealing from the last guy who didn’t understand coastal installation. We do, because we’ve been doing this on Long Island for over a decade. You get a leak-free guarantee, not a temporary fix that fails next season.
We’ve spent over 10 years replacing skylights across Suffolk County. We’re not a general contractor dabbling in roofing—we specialize in the exact challenges Southold homeowners face. Salt air that corrodes flashing. Nor’easters that test every seal. Ice dams that form along skylight edges when your attic’s too warm.
We install Velux skylights because they’re engineered for this climate and backed by real warranties. Our crews know how to flash a skylight so it doesn’t leak in year three when the sealant finally gives out. We’ve repaired hundreds of botched installations from contractors who didn’t account for Long Island’s weather, and we’ve seen what fails.
You’re hiring local expertise, not a crew learning on your roof. Every installation comes with our leak-free guarantee and the kind of workmanship that keeps your skylight functional for decades, not seasons.
We start with an inspection of your current skylight and the roof deck around it. Most leaks aren’t obvious from inside—they’re hidden in the flashing or where the skylight meets your shingles. We check for rot, failed sealant, and whether your attic ventilation is causing condensation issues that look like leaks but aren’t.
Once we know what’s wrong, we give you a flat-rate quote. No surprises, no upsells. If you’re replacing the skylight, we remove the old unit carefully to avoid damaging your roof deck. Then we install new flashing—the metal framework that keeps water out—using a system designed for Long Island’s freeze-thaw cycles. The new Velux skylight goes in with proper sealing, and we integrate it with your existing shingles so water flows around it, not under it.
Most single skylight replacements take four to six hours. We test everything before we leave, and you get documentation of the work plus warranty details. If it’s an emergency repair, we can stop the leak temporarily and schedule the full replacement as soon as weather permits. You’re not waiting weeks with a tarp on your roof.

You get a full skylight removal and replacement with coastal-grade flashing designed for Suffolk County weather. We install energy-efficient Velux skylights with double-pane glass that cuts heat loss in winter and reduces solar gain in summer. These aren’t the builder-grade plastic domes that yellow and crack—they’re engineered units with integrated flashing systems that actually work with your roof.
Every installation includes our leak-free guarantee and a comprehensive workmanship warranty. Velux backs their products with up to 10 years on materials, and we stand behind the installation for as long as you own your home. If it leaks because of our work, we fix it at no cost.
Southold homes deal with unique challenges. You’re getting an average of 27 to 30 inches of snow each winter, and those melt-freeze cycles are brutal on skylights. We account for ice dam formation, wind-driven rain, and the salt air that accelerates corrosion on metal components. Your skylight is sealed and flashed to handle all of it, not just the easy days. Most replacements cost between $2,000 and $5,300 depending on size and roof access, and we offer financing for qualified homeowners.
If your skylight is leaking in multiple spots, showing condensation between the panes, or older than 15 years, replacement usually makes more sense than repair. Southold’s coastal weather is hard on skylights—salt air corrodes the flashing, freeze-thaw cycles crack seals, and UV exposure degrades plastic domes over time.
Here’s the test: if you’ve already patched it once and it’s leaking again, the skylight itself is likely failing. Three out of four skylight leaks come from the unit, not the installation. Repairing old flashing or adding more caulk just delays the inevitable. Modern Velux skylights are 35% more energy efficient than older models, so you’re also losing money on heating and cooling with an outdated unit.
We’ll inspect your skylight and roof deck to give you an honest answer. Sometimes a flashing repair is enough. But if the skylight’s compromised, replacement is the only permanent fix. You’ll save more in the long run by doing it right once instead of paying for repairs every few years.
Most skylight leaks in Southold happen because the flashing fails, not the skylight glass. Flashing is the metal framework that channels water around the skylight and down your roof. When it’s installed incorrectly or corrodes from salt air, water seeps underneath and into your attic. You see stains on your ceiling, but the real damage is happening in the roof deck where you can’t see it.
Long Island’s freeze-thaw cycles make this worse. Water gets into small gaps in the flashing, freezes overnight, expands, and cracks the seal wider. By spring, you’ve got a leak that wasn’t there in the fall. Ice dams are another culprit—when heat escapes from your attic, it melts snow on your roof. That water runs down, refreezes near the skylight edge, and forces moisture under the flashing.
Poor installation is the other major cause. If the previous contractor didn’t integrate the flashing with your shingles correctly, or used cheap sealant instead of proper weatherproofing, you’re going to have problems. We see this constantly—DIY jobs or low-bid contractors who don’t understand coastal roofing. Fixing it right means removing the skylight, replacing the flashing with corrosion-resistant materials, and sealing it to handle Southold’s weather year-round.
Most single skylight replacements take four to six hours from start to finish. We’re usually done in one day, weather permitting. If you’re replacing multiple skylights or we find rot in the roof deck that needs repair, it might take longer—but we’ll tell you that upfront after the inspection.
The process moves quickly because we’re not rebuilding your roof. We remove the old skylight, inspect and repair the roof deck if needed, install new flashing, and set the new Velux unit in place. The longest part is making sure the flashing integrates correctly with your existing shingles so water flows around the skylight instead of pooling near it. That’s where most contractors cut corners, and it’s why their installations leak two years later.
You don’t need to leave your home, but you’ll hear noise on the roof and maybe some vibration if we’re working directly above you. We clean up all debris and old materials before we leave. If weather turns bad mid-job, we’ll weatherproof the opening and come back to finish as soon as it’s safe. You’re never left with an open hole in your roof.
Yes, and the difference is significant. Modern Velux skylights can be up to 35% more energy efficient than the plastic skylights installed in most Southold homes 15 or 20 years ago. That translates to about $10 to $15 per month in savings on your electric bill, depending on the size of the skylight and how much direct sun it gets.
Older skylights lose heat in winter because the seals degrade and the glass isn’t insulated. You’re paying to heat your home, and that warm air is escaping through the skylight. In summer, cheap skylights let in too much solar heat, so your AC works harder to keep the house cool. ENERGY STAR certified skylights reduce heating and cooling costs by up to 13% when installed correctly—that’s real money over the lifespan of the unit.
Double-pane glass makes the biggest difference. It reduces heat transfer and cuts down on condensation, which is a huge problem in Long Island’s humid climate. If you’re seeing moisture between the panes on your current skylight, the seal is shot and you’re losing energy every day. Replacing it with a modern unit pays for itself over time, and you’ll notice the difference immediately in how comfortable your home feels.
Yes, we provide 24/7 emergency skylight repair throughout Southold and Suffolk County. If your skylight is actively leaking and causing water damage, we’ll get there as fast as we can to stop it. Emergency repairs usually involve temporary weatherproofing—tarping the skylight, sealing obvious gaps, or covering the area until we can do a permanent fix.
Most skylight emergencies happen during storms or after heavy snow when ice dams form and force water under the flashing. You’ll see water dripping from your ceiling or pooling in your attic, and it needs to be addressed immediately before it damages your drywall, insulation, or roof deck. We’ll stabilize the situation, assess what’s causing the leak, and schedule a full repair or replacement as soon as weather allows.
Permanent fixes can’t always happen in the middle of a nor’easter—it’s not safe to work on your roof in high winds or ice, and any repair we attempt won’t hold. But we’ll make sure your home is protected in the short term and give you a clear timeline for the real solution. If the skylight needs replacement, we’ll walk you through options and pricing so you can make an informed decision without the pressure of water pouring into your house.
Skylight replacement costs in Southold typically range from $2,000 to $5,300, and the variation comes down to skylight size, roof access, and whether we’re fixing damage from the old installation. A small fixed skylight on an accessible roof costs less than a large vented unit on a steep pitch where we need special equipment and more labor hours.
The skylight itself is a big factor. Velux units cost more than builder-grade options, but they’re engineered for Long Island’s climate and come with real warranties. Cheap skylights fail faster, especially in coastal areas where salt air corrodes metal components and UV exposure degrades plastic. You’ll pay less upfront and more over time in repairs and energy loss. We install Velux because they last and because we’re not interested in coming back to fix the same skylight in five years.
Roof deck condition also affects cost. If the previous skylight was leaking for a while, there’s often rot in the wood decking around it. We have to replace that before installing the new skylight, or you’re just putting a good unit on a compromised structure. We’ll know after the inspection and give you a flat-rate quote that includes everything—no surprise charges when we’re halfway through the job. Financing is available if you need it, and we’ll work with you to find a solution that fits your budget without cutting corners on quality.
