Hear From Our Clients
You flip the light switch in your hallway at 2 PM on a sunny day. Your bathroom fan runs constantly because there’s no ventilation. Your ceiling has water stains from the last storm, and you’re wondering if this skylight is going to make it through another winter.
Most skylights fail the same way. The seals crack from temperature swings. The flashing wasn’t installed correctly in the first place. The glass is single-pane from 1995, and it’s bleeding heat straight through your roof.
A professional skylight replacement fixes all of it. You get modern, double-pane glass with Low-E coatings that block heat transfer while letting natural light flood your space. You get integrated flashing systems that actually prevent leaks instead of just delaying them. You get up to five times more natural light than a standard window, which means you’re not burning electricity all day. And you get energy savings between 10-15% monthly because your HVAC system isn’t working overtime to compensate for an inefficient skylight.
This isn’t about making your home look better—though it does. It’s about solving the problems that cost you money and stress every month.
We’ve spent over 10 years working on homes across Suffolk County. We’re a family-owned company, fully licensed and insured, and we’ve seen what Long Island weather does to skylights that weren’t installed correctly.
We’ve pulled out skylights that leaked from day one because the contractor didn’t understand flashing. We’ve replaced units that cracked under snow load because nobody calculated the pitch right. We’ve fixed damage from coastal humidity that warped seals and frames because the materials weren’t suited for salt air.
Brookhaven homeowners deal with specific challenges. You’re getting 27 to 30 inches of snow most winters. You’re getting coastal moisture year-round. Your home is worth $700K on average, and you’re not looking for the cheapest option—you’re looking for someone who gets it right the first time. That’s what we do.
First, we come out and assess your current skylight. We’re looking at the condition of the glass, the seals, the flashing, and the interior finish. We’re checking for water damage, measuring the opening, and figuring out what caused the problem in the first place. Most skylight leaks come from improper installation, not the skylight itself.
Once we know what you’re dealing with, we walk you through your options. If you want a fixed skylight for natural light, we’ll recommend units with the right glazing for your space. If you need ventilation—especially in bathrooms or kitchens—we’ll talk about operable skylights that actually move air. If you’re concerned about energy costs, we’ll show you the difference between standard glass and Low-E coatings with insulated frames.
The installation itself starts with removing the old unit and inspecting the roof deck for damage. We replace any compromised materials, then install the new skylight with integrated flashing that ties directly into your roofing system. We’re creating multiple waterproof barriers, not just slapping a skylight on top of shingles and hoping for the best. Then we finish the interior, seal everything properly, and test it before we leave.
You’re not guessing whether it’s going to leak next time it rains. You know it won’t.

A professional skylight replacement in Brookhaven typically costs between $2,000 and $5,300, depending on the size, type, and complexity of the installation. That includes the skylight itself, all flashing and waterproofing materials, labor, and interior finishing.
You’re getting modern VELUX or comparable skylights designed for Long Island’s climate. These units come with Low-E glass coatings that reflect heat while letting light through, double or triple-pane glazing that insulates better than anything from 15 years ago, and warranties that actually mean something. If you want ventilation, you can add rain sensors and solar-powered operation that opens and closes automatically.
The flashing system is where most contractors cut corners, and it’s why most skylights leak. We use integrated flashing kits that tie directly into your shingles, creating a continuous weather barrier from the skylight to the roof deck. We calculate the slope correctly so water doesn’t pool. We seal every seam and test every joint before we move to the next step.
Brookhaven gets hit with winter storms that dump heavy snow and freezing rain. Your skylight needs to handle that load without cracking or leaking. The materials we use and the way we install them make the difference between a skylight that lasts 20 years and one that fails in five.
Most residential skylight replacements take one to two days, depending on the size of the skylight and whether we’re dealing with any roof deck damage. If your skylight is standard-sized and the surrounding structure is in good shape, we can usually complete the job in a single day.
The timeline changes if we find rot or water damage once we remove the old unit. That’s not uncommon with skylights that have been leaking for a while. We’ll need to replace any compromised decking or framing before we install the new skylight, which can add a few hours or another day to the project.
Weather also plays a role. We’re not installing skylights in the middle of a rainstorm or when snow is forecasted. We need dry conditions to properly seal and flash the unit. If we have to pause the job due to weather, we’ll make sure your roof is fully protected with tarps and temporary coverings until we can finish.
Yes, if the skylight is installed correctly. About 75% of skylight leaks come from improper installation, not the skylight itself. The flashing wasn’t integrated properly, the seals weren’t done right, or the contractor didn’t account for water flow across the roof.
When we replace your skylight, we’re not just swapping the unit. We’re removing the old flashing, inspecting the roof deck for damage, and installing a complete waterproofing system that ties the skylight into your existing roofing. We use integrated flashing kits designed specifically for your roof type—whether that’s asphalt shingles, metal, or tile. We’re creating multiple barriers so water can’t get through even if one layer fails.
The other 25% of leaks come from the skylight itself—cracked seals, failed gaskets, or condensation issues. A modern skylight eliminates those problems with better materials and better engineering. You’re getting insulated glass that doesn’t condensate, weatherproof seals that don’t crack in freezing temperatures, and frames built to handle Long Island’s coastal humidity without warping.
Most homeowners in Brookhaven pay between $2,000 and $5,300 for a complete skylight replacement. The cost depends on the size of the skylight, the type you’re installing, and how much prep work is needed on the roof deck.
A basic fixed skylight in a standard size with minimal roof repairs will land closer to $2,000. If you’re installing a larger unit, adding ventilation features, or dealing with roof deck damage from years of leaks, you’re looking at the higher end of that range. Custom sizes, solar-powered operation, and premium glass options will also increase the cost.
Here’s what you’re paying for: the skylight itself, all flashing and waterproofing materials, removal of the old unit, any necessary roof deck repairs, professional installation with proper sealing, and interior finishing. You’re also paying for someone who knows how to install it correctly the first time, which is worth more than you think. A cheap installation that leaks in six months ends up costing you thousands in water damage and a second replacement.
If your skylight is less than 10 years old and the problem is minor—like a cracked seal or a small flashing issue—a repair might make sense. But if your skylight is over 15 years old, leaking regularly, or showing signs of frame damage, you’re better off replacing it.
Here’s why: older skylights were built with single-pane glass, outdated seals, and flashing systems that don’t meet current standards. You can patch a leak, but you’re not fixing the underlying problem. The glass is still inefficient. The frame is still compromised. And you’re probably going to be calling someone back in a year or two when it starts leaking again.
Replacement gives you a modern skylight with double or triple-pane glass, Low-E coatings, and integrated flashing that actually works. You’re getting better energy efficiency, better waterproofing, and a warranty that covers the unit and the installation. The cost of repeated repairs on an old skylight often approaches the cost of replacement—except with repairs, you’re still stuck with an outdated, inefficient unit.
Yes. VELUX makes some of the best residential skylights available, and we install them regularly in Brookhaven and across Suffolk County. They’re engineered for durability, energy efficiency, and weather resistance—exactly what you need for Long Island’s climate.
VELUX skylights come with features that older units don’t have: Low-E glass coatings that block heat transfer, insulated frames that prevent condensation, and integrated flashing kits designed to work with your specific roof type. If you want ventilation, they offer models with rain sensors that automatically close when it starts to storm, and solar-powered operation so you’re not running wiring through your roof.
We also work with other quality manufacturers depending on your needs and budget. What matters most isn’t the brand—it’s the installation. A VELUX skylight installed incorrectly will leak just like any other skylight. We’re trained on proper installation techniques, we follow manufacturer specifications, and we use the flashing systems and sealing methods that actually prevent leaks. That’s what makes the difference.
We can, but it depends on the weather conditions during the specific days we’re working. Skylight replacement requires dry conditions and temperatures above freezing for proper sealing and flashing. If we’re in the middle of a cold snap or snow is forecasted, we’ll need to wait for a clear window.
That said, we do plenty of winter skylight replacements in Brookhaven. We just need a stretch of dry days with reasonable temperatures. We’ll monitor the forecast closely and schedule your installation when conditions are right. If we have to adjust the timeline due to weather, we’ll let you know immediately and reschedule as soon as possible.
If your skylight is leaking and causing active water damage, we can provide temporary repairs to stop the leak until we’re able to complete the full replacement. We’re not going to leave you with a tarp on your roof for three months. We’ll get it handled as quickly as weather allows, and we’ll make sure your home is protected in the meantime.
