You’re not dealing with a leaking skylight because you ignored it. You’re dealing with it because the original installation wasn’t done properly, or because 15 years of Suffolk County weather finally wore it down. Either way, the water damage adds up fast—ceilings, insulation, even structural wood if it’s been going on long enough.
A proper skylight replacement stops that cycle. You get a unit that’s built for Long Island’s freeze-thaw winters and coastal humidity, installed with integrated flashing and multiple waterproof barriers. The kind of setup that doesn’t fail when the next storm rolls through.
You also get better energy performance. Older skylights leak air just as much as they leak water. Modern units with Low-E glass and insulated frames can cut your heating and cooling costs by 10 to 15 percent. That’s real money back in your pocket every month, and it makes the rooms under your skylight more comfortable year-round.
We’ve been handling roof skylight replacement and full roofing projects across Suffolk County for over a decade. We’re not a national franchise or a crew that drives in from somewhere else. We live here, we work here, and we know what North Sea homes go through when winter hits.
That means we understand how ice dams form along your roofline, how salt air affects flashing, and why a skylight that works fine in Virginia might fail in six months on Long Island. We’ve seen what happens when shortcuts get taken, and we’ve fixed plenty of those jobs. Our approach is straightforward—assess the situation honestly, recommend what actually solves it, and install it so you don’t have to think about it again.
We start with a free inspection. That means someone comes out, gets on your roof, and looks at the skylight, the flashing, the surrounding shingles, and the interior ceiling for signs of ongoing damage. You get an honest assessment of whether you need a full replacement or if there’s a smaller fix that makes sense. If replacement is the right call, we walk you through your options—Velux skylights are what we recommend most often because they’re built to last and come with solid warranties.
Once you’re ready to move forward, we schedule the install. Most single skylight replacements take four to six hours and get done in one day. We protect your interior with tarps, remove the old unit carefully, inspect and repair any damaged decking, then install the new skylight with proper flashing and weatherproofing. Everything gets sealed correctly the first time, which is why about 75 percent of skylight leaks don’t come from the skylight itself—they come from improper flashing during installation.
After the install, we clean up completely and walk you through how the new unit operates, especially if it has features like rain sensors or remote controls. You’re left with a skylight that works, a roof that’s watertight, and no mess to deal with.

Every skylight replacement we do in North Sea includes removal of your old unit, inspection of the roof decking and framing, and installation of a new energy-efficient skylight with integrated flashing. We’re not reusing old flashing or trying to make a new skylight fit into an old opening that’s rotted out. If there’s damage to the wood decking or rafters, we repair that first so the new skylight sits on a solid foundation.
You’re also getting a unit that’s built for this climate. Velux skylights come with insulated glass, durable frames, and warranties that actually mean something. If you want upgrades like solar-powered blinds, rain sensors, or venting options, we can add those. Most North Sea homeowners are dealing with older homes that have single-pane skylights from the 90s or early 2000s, and the difference in performance is immediate—less condensation, better insulation, and way more natural light without the heat gain.
The other thing you’re getting is proper permitting and code compliance. Suffolk County has specific requirements for roof penetrations, and we handle all of that. You don’t have to worry about whether the job was done legally or if it’ll cause problems when you go to sell.
Most skylight replacements in North Sea run between $1,500 and $4,000 depending on the size of the unit, the type of skylight you choose, and whether there’s any underlying damage to the roof structure. A standard curb-mounted Velux skylight replacement on a home with accessible roof access and no wood rot typically falls in the $2,000 to $3,000 range. That includes removal of the old skylight, new flashing, the skylight itself, installation labor, and cleanup.
If you’re replacing a larger unit, adding features like solar-powered shades or ventilation, or if we find rotted decking that needs repair, the cost goes up. Custom sizes or deck-mounted skylights that require more structural work can push toward $5,000 or more. The good news is we give you an upfront price after the inspection, so there’s no guessing. You’ll know exactly what it costs before we start, and we can discuss financing options if that helps.
Most single skylight replacements take between four and six hours and get finished in one day. We show up in the morning, protect your interior, remove the old skylight, make any necessary repairs to the roof deck, install the new unit with proper flashing, seal everything, and clean up. You’re usually looking at the finished job by early afternoon.
If you’re replacing multiple skylights or if we run into structural issues that need more extensive repair, it might take a full day or stretch into a second day. Weather can also be a factor—we’re not going to leave your roof open if a storm’s coming, so we plan around the forecast. But in general, skylight replacement is one of the faster roofing jobs we do, and most North Sea homeowners are surprised how quick and clean the process is.
If it’s installed correctly, yes. The reason most skylights leak isn’t because the skylight itself is defective—it’s because the flashing wasn’t installed right in the first place. About 75 percent of skylight leaks come from improper flashing, which is the metal or rubberized material that creates a waterproof seal between the skylight and your roof.
When we replace a skylight, we’re not reusing old flashing or trying to patch around it. We install new integrated flashing that’s designed specifically for the skylight model you’re getting, and we layer it correctly with your shingles so water has no way to get through. We also use multiple waterproof barriers and check that the skylight is level and properly sealed. That’s why we can offer a leak-free guarantee—because we’re doing the install the way it’s supposed to be done. If your skylight was leaking before and you get it replaced properly, that problem is solved.
Sometimes, but not usually. If your skylight is relatively new and the leak is coming from a small flashing issue or a cracked seal that we can access and fix, a repair might make sense. But if your skylight is 15 years old or more, if the glass is fogged or cracked, if the frame is warped, or if you’re dealing with repeated leaks, replacement is almost always the smarter move.
Here’s why—older skylights don’t have the energy efficiency or build quality of modern units, and even if we stop the leak temporarily, you’re still losing heat in the winter and gaining it in the summer. Repair costs can also add up quickly, and if you’re spending $800 to $1,200 on a repair for a skylight that’s near the end of its life anyway, you’re better off putting that money toward a replacement that comes with a warranty and will last another 20 years. We’ll tell you honestly during the inspection whether a repair makes sense or if you’re just delaying the inevitable.
Repair means we’re fixing a specific issue with your existing skylight—replacing a section of flashing, resealing the glass, or patching a small crack. Replacement means we’re removing the entire skylight and installing a new one. The decision usually comes down to the age and condition of your current unit.
If your skylight is less than 10 years old and the problem is isolated, a repair can work. But if it’s older, if you’re dealing with condensation between the panes, if the frame is deteriorating, or if the skylight has leaked multiple times, replacement is the right call. You’re not just fixing the immediate problem—you’re upgrading to a unit that performs better, looks better, and comes with a manufacturer warranty. Most North Sea homes we work on have skylights that are 15 to 25 years old, and at that point replacement isn’t just recommended, it’s necessary.
Yes. Velux is what we install most often because they’re the most reliable skylight brand for Long Island’s climate. They’re built to handle temperature swings, they come with strong warranties, and they have the best track record for long-term performance. Velux also makes it easy to get replacement parts if you ever need them down the road, which isn’t true for a lot of other brands.
We can install other brands if you have a specific preference, but when homeowners ask what we recommend, it’s Velux. Their skylights come with insulated Low-E glass, durable frames, and integrated flashing kits that are designed to work together. They also offer features like solar-powered shades, rain sensors, and remote operation, which a lot of North Sea homeowners appreciate. If you’re replacing an old skylight, going with Velux means you’re getting a unit that’s going to perform well and last.
