Hear From Our Clients
You stop worrying about the next rainstorm. No more buckets on the floor, no more stained ceilings, no more wondering if water’s seeping into places you can’t see yet.
A proper skylight replacement means new flashing, new seals, and materials built for Long Island’s freeze-thaw cycles. You’re not patching over the same problem—you’re eliminating it. Most jobs finish in a day, and you walk away with a warranty that actually means something.
The other benefit most people don’t think about until they see their next utility bill: modern skylights with Low-E glass can cut your heating and cooling costs by 10-15% monthly. That’s real money back in your pocket, month after month. And if you’re thinking about selling down the road, buyers notice natural light—it photographs well and makes rooms feel bigger than they are.
We’ve been handling roof skylight replacement across Long Island for over a decade. We’re not a national franchise or a crew that shows up once and disappears—we live here, work here, and our reputation depends on doing the job right.
Northport homeowners deal with specific challenges: coastal salt air, temperature swings, and older homes with unique roof structures. We’ve seen what fails and what lasts. That’s why we install VELUX skylights with integrated flashing systems designed for this exact climate.
You get licensed contractors, upfront pricing, and a crew that treats your home like it’s their own. No runaround, no surprises.
First, we assess your current skylight and roof structure. Most leaks aren’t just the glass—they’re failed flashing or degraded seals around the frame. We’ll tell you exactly what’s causing the problem and what it’ll cost to fix it permanently.
Once you approve the estimate, we schedule the work around your life and the weather. On installation day, we protect your interior with tarps and drop cloths, then carefully remove the old skylight. We inspect the roof deck for any hidden water damage—if there’s rot, you’ll know about it before we go further.
The new skylight goes in with fresh flashing, multiple waterproof barriers, and proper integration with your existing roofing material. We test the seal, clean up completely, and walk you through the warranty. Most single skylight replacements take 4-6 hours. You’re not left with an open roof overnight, and you’re not dealing with a mess inside your home.
Ready to get started?
You’re getting a complete system, not just a new piece of glass. That means removal of your old skylight, inspection of the roof deck and surrounding structure, and installation of a new VELUX skylight with integrated flashing designed for Long Island weather.
We handle all interior protection, debris removal, and site cleanup. If we find underlying damage during removal—rotted decking, compromised insulation, or mold—we’ll show you exactly what needs attention before we seal everything back up. No one wants surprises, but finding problems early beats discovering them after the next storm.
In Northport, where homes range from historic builds to modern construction, every roof is a little different. We adjust our approach based on your roof pitch, material, and age. Financing options are available, including 18-month interest-free plans, so you’re not stuck choosing between a leaking skylight and your budget. The work comes with a leak-free installation guarantee and manufacturer warranty on materials.
Most residential skylight replacements in Northport run between $1,000 and $2,500 per skylight, depending on size, roof access, and whether there’s any underlying damage that needs repair. That’s for a complete replacement with new flashing and proper sealing—not a temporary patch.
If your skylight is over 15 years old and you’re already spending $450-$1,000 on repairs, replacement usually makes more financial sense. You get new energy-efficient glass, a fresh warranty, and you stop throwing money at a problem that’s only going to get worse. We give you upfront pricing before any work starts, so you know exactly what you’re paying for.
Most single skylight replacements finish in one day—typically 4-6 hours from start to cleanup. We’re not leaving your roof open overnight or dragging the job out over multiple visits.
Weather can delay things, obviously. If conditions aren’t safe, we’ll reschedule rather than rush through a job that needs to be watertight. But once we start, the process moves quickly: old skylight out, roof deck inspected, new skylight installed with proper flashing, everything sealed and tested. You can plan your day around it without wondering when your house will be put back together.
If your skylight is less than 10 years old and the leak is clearly from damaged flashing or a broken seal, repair might make sense. But if it’s older than 15 years, or if you’ve already paid for repairs that didn’t hold, replacement is usually the smarter move.
Here’s why: older skylights lack the energy efficiency of modern units, so you’re losing money on heating and cooling every month. The materials degrade over time—seals dry out, plastic yellows and cracks, and flashing fails during freeze-thaw cycles. Repairs on old units often cost nearly as much as replacement, but you’re still left with an aging system that’ll need more work soon. Replacement gives you a fresh start, better energy performance, and a warranty that actually protects you.
The number one cause is improper flashing installation. Flashing is the metal barrier that keeps water from seeping between your skylight and roof—if it’s not integrated correctly with your roofing material, water finds a way in. This is especially common in Suffolk County because of our freeze-thaw cycles, which expand and contract materials and break seals that weren’t installed right in the first place.
The second issue is age. Seals and gaskets deteriorate over time, especially on skylights with plastic domes that get brittle from UV exposure. You’ll also see leaks from condensation that looks like a leak but is actually moisture buildup from poor ventilation or single-pane glass. A proper inspection tells you exactly what’s failing so you’re not guessing or paying for the wrong fix.
Yes, if you’re replacing an old single-pane or plastic skylight with a modern double-pane unit that has Low-E glass. The difference is measurable—most homeowners see 10-15% reductions in monthly heating and cooling costs, which adds up to real savings over the life of the skylight.
Older skylights are basically holes in your insulation. Heat escapes in winter, and in summer you’re air-conditioning the outdoors. Modern VELUX skylights with ENERGY STAR ratings are built to insulate, not just let in light. You get the natural light benefits—up to five times more than a standard window—without the energy penalty. That’s why replacement often pays for itself over time, especially if you’re planning to stay in your home for more than a few years.
Check three things: licensing, local reputation, and whether they’re actually experienced with skylights specifically. A lot of roofing companies will handle skylight work, but they’re not specialists—they often downplay problems or use generic flashing that doesn’t integrate properly with the skylight system.
Ask if they’re certified to install the brand they’re recommending. VELUX, for example, has a certified installer network, and that certification means they’ve been trained on proper installation techniques. Look for companies that have been working in Suffolk County for years, not crews passing through. And get everything in writing—scope of work, materials being used, timeline, and warranty terms. If a contractor won’t put it in writing or pressures you to decide on the spot, that’s your signal to walk away.
