Your skylight stops leaking. Not temporarily—permanently. When flashing is installed correctly and the unit is actually designed for Long Island’s freeze-thaw cycles, you don’t get callbacks or water stains six months later.
Your energy bills drop. Velux skylights are up to 35% more efficient than older plastic units, which can save you $10-15 monthly on electricity. That adds up over a 20-year lifespan.
You get five times more natural light than a standard window of the same size. Rooms feel bigger, brighter, and more comfortable without running lights all day. If you choose a vented model, hot air escapes naturally in summer, which means your AC isn’t working overtime to cool the second floor.
Most single skylight replacements take four to six hours. You’re not dealing with a multi-day project that disrupts your routine. We show up, we handle it, and you’re back to normal by dinner.
We’ve been handling roof skylight replacement across Long Island for over two decades. We’re licensed, insured, and based right here in Suffolk County—which means we understand what nor’easters do to improperly installed skylights.
We’ve seen which brands hold up and which ones fail after three winters. That’s why we install Velux skylights with proper flashing and waterproofing, backed by our leak-free guarantee. Selden homeowners deal with the same weather challenges as the rest of the county: heavy snow loads, ice damming, and humidity that tests every seal.
You’re not getting a crew that learned skylight installation from YouTube. You’re getting professionals who’ve done hundreds of these jobs and know exactly how to handle flat roofs, pitched roofs, and the tricky spots where most leaks start.
We start with a free inspection of your current skylight. We’re looking at the condition of the glass or acrylic, the flashing, the curb, and the surrounding roofing material. If you’ve got leaks, we trace them to the actual source—not just where the water shows up inside.
You get upfront pricing before any work starts. No surprises, no hidden fees. If your skylight is 15+ years old and showing multiple issues, we’ll tell you straight up whether repair or replacement makes more financial sense.
On installation day, we remove the old unit carefully to avoid damaging your roof deck or interior ceiling. We inspect the opening, replace any compromised decking, and install the new Velux skylight with manufacturer-spec flashing. Every overlap, every seal, every fastener gets done right the first time.
We handle all the weatherproofing and integrate the new flashing with your existing roofing material. Then we test it. Most jobs wrap up in one day, weather permitting. You get a clean site, a warranty on parts and labor, and a skylight that’s engineered to handle everything Suffolk County throws at it.

Every residential skylight replacement includes removal of your old unit, proper disposal, and inspection of the roof deck and framing. If we find rot or damage—which is common with long-term leaks—we handle those repairs before the new skylight goes in.
You get a Velux skylight sized correctly for your opening. These units are engineered for climates like ours, with insulated glass that handles temperature swings without condensation issues. If you want ventilation, we install models with rain sensors that automatically close when moisture is detected.
The flashing system is critical, and it’s where most DIY jobs and cheap contractors fail. We use Velux flashing kits designed specifically for your roof type—shingle, metal, or flat. Every piece overlaps correctly with your roofing material to create a watertight seal that holds up through freeze-thaw cycles.
Selden homeowners also get our leak-free guarantee and access to financing options for qualified buyers. The typical cost for skylight replacement ranges from $800 to $2,500 per unit depending on size, roof access, and whether you’re going with a fixed or vented model. We walk you through options that fit your budget and your home’s needs.
If your skylight is leaking in multiple spots, showing condensation between panes, or is over 15 years old, replacement usually makes more sense than repair. Here’s why: most skylights have a functional lifespan of 15 to 20 years, and once they start failing, you’re chasing problems.
A single leak caused by damaged flashing might be repairable if the skylight itself is in good shape and relatively new. But if the acrylic is yellowed and brittle, the seals are compromised, or you’ve already paid for repairs that didn’t last, you’re throwing money at a unit that’s reached the end of its life.
We’ll give you an honest assessment during the free inspection. If a repair will actually solve the problem, we’ll tell you. But if you’re looking at a skylight that’s going to need replacement in the next few years anyway, it makes more financial sense to do it now and stop dealing with leaks and energy loss.
Velux skylights are engineered for durability and energy efficiency in climates that get real weather. After 20 years of installations, we’ve seen which brands hold up through Long Island winters and which ones crack, leak, or fog up after a few seasons.
Velux uses insulated, tempered glass with low-E coatings that reduce heat transfer. That means less heat loss in winter and less solar gain in summer—up to 35% more efficient than older plastic skylights. They’re also built with proper drainage channels and weatherstripping that actually works when temperatures drop below freezing.
The flashing systems are designed to integrate with different roof types without creating weak points where water can penetrate. Velux backs their products with real warranties, and replacement parts are actually available if you ever need them. Cheaper brands might save you money upfront, but you’ll pay for it in energy costs and premature failure.
Most single skylight replacements take four to six hours from start to finish. We typically complete the work in one day, weather permitting. If you’re replacing multiple skylights or we discover roof deck damage that needs repair, it might extend into a second day.
The timeline depends on a few factors: roof pitch, accessibility, whether we’re working with a flat roof or pitched roof, and the condition of the existing opening. Flat roof skylights on commercial-style homes sometimes take a bit longer because the curb and flashing details are more involved.
You won’t have an open hole in your roof overnight. We don’t start removal until we’re ready to install the new unit and complete the weatherproofing the same day. If weather rolls in unexpectedly, we have temporary protection methods to keep your home secure, but that’s rare because we monitor forecasts closely and don’t start jobs when conditions look questionable.
Yes, if your current skylight is old and inefficient. Older plastic skylights—especially single-pane or non-insulated models—are major sources of heat loss in winter and unwanted heat gain in summer. Your HVAC system works harder to compensate, which drives up utility bills year-round.
A new Velux skylight with insulated, low-E glass can be up to 35% more energy efficient. That translates to roughly $10-15 per month in electricity savings, depending on your home’s size and how many skylights you have. Over a 20-year lifespan, that’s real money back in your pocket.
Energy efficiency also affects comfort. If you’ve noticed cold drafts near your skylight in winter or excessive heat in summer, that’s a sign the unit isn’t performing. A properly installed, energy-efficient skylight maintains more consistent indoor temperatures, which means fewer hot and cold spots and less strain on your heating and cooling systems.
Most skylight leaks come from improper flashing installation, not the skylight itself. Flashing is the metal or rubberized material that creates a watertight seal between the skylight and your roof. If it’s not overlapped correctly with shingles, if corners aren’t sealed properly, or if the wrong type of flashing is used for your roof pitch, water finds a way in.
Suffolk County’s freeze-thaw cycles make this worse. Water gets into small gaps, freezes overnight, expands, and creates bigger openings. What starts as a minor issue becomes a major leak within a season or two. We prevent this by using manufacturer-spec Velux flashing kits designed for your specific roof type and following installation procedures exactly.
The other common cause is age-related seal failure. The gaskets and weatherstripping around the skylight break down over time from UV exposure and temperature extremes. Once those seals fail, water penetrates even if the flashing is perfect. That’s why replacement makes more sense than repair for older units—you’re addressing the root cause, not just patching symptoms.
Skylight replacement typically costs between $800 and $2,500 per skylight, including the unit, flashing, labor, and our leak-free guarantee. The price depends on the size of the skylight, roof accessibility, whether you’re choosing a fixed or vented model, and if there’s any roof deck repair needed.
A standard fixed Velux skylight on an accessible pitched roof with no structural issues falls on the lower end. Larger units, flat roof installations, or vented models with rain sensors and remote controls cost more. If we find rotted decking or framing damage during removal—common with long-term leaks—that repair adds to the total, but we give you pricing before proceeding.
Financing is available for qualified homeowners, which makes it easier to handle the upfront cost while you start seeing energy savings immediately. We provide transparent, upfront pricing during the free inspection so you know exactly what you’re paying for. No hidden fees, no surprises when the job’s done.
