You know the drill. Storm’s coming, and you’re already thinking about that skylight. Where you put the bucket last time. Whether the stain on the ceiling got bigger. Whether this is the storm that finally does real damage.
That stops here. A proper skylight window replacement means new flashing, coastal-grade seals, and glass that doesn’t fog up or leak when the temperature drops. Most jobs take 4-6 hours, and you’re done worrying.
You also stop losing money every month. Older skylights let heat escape in winter and pour in during summer. Modern Velux skylights can be up to 35% more energy efficient, which typically saves $10-15 monthly on your electric bill. That adds up fast, and your rooms stay comfortable year-round without cranking the thermostat.
The right skylight replacement handles Long Island’s freeze-thaw cycles, salt air, and heavy snow without cracking seals or corroding frames. You get natural light that actually brightens your space instead of a cloudy, yellowed panel that barely lets anything through.
We’ve spent over a decade fixing roofs and skylights in Suffolk County. We’re licensed, insured, and we don’t use subcontractors. Every person on your roof works directly for us and knows exactly how coastal weather tears up skylights.
Hauppauge homes deal with the same problems we see across Long Island: salt air corroding metal flashing, freeze-thaw cycles cracking seals, and storms that test every weak point on your roof. We’ve handled hundreds of skylight replacements, and our 4.9-star rating across 400+ reviews reflects how we approach every job.
You get a transparent estimate before we start, quality materials designed for this climate, and a team that shows up when we say we will. No runaround, no surprises, no subcontractors who don’t know your property.
First, we inspect your current skylight and the roof around it. Most leaks aren’t the glass—they’re improper flashing or degraded seals. We check the frame, the surrounding shingles, and whether water’s been getting into your decking. You get a clear explanation of what’s wrong and what it takes to fix it permanently.
Once you approve the estimate, we schedule installation around your timeline and the weather. We remove your old skylight carefully to avoid damaging the roof structure, then inspect the opening for any rot or damage that needs addressing before the new unit goes in.
The new skylight gets installed with step flashing around the sides and continuous flashing at the head and sill. Everything’s sealed with high-grade materials made for Long Island’s climate. We match your roofing material around the skylight so it looks like it’s always been there, then clean up completely.
Most single residential skylight replacement jobs finish in one day, weather permitting. You’re left with a skylight that doesn’t leak, doesn’t fog, and actually does what it’s supposed to do—let in light without letting in water.
Ready to get started?
Every home skylight replacement includes removal of your old unit, proper disposal, and installation of a new Velux skylight with integrated flashing systems. You’re getting impact-resistant glass, coastal-grade seals, and frames built to handle humidity and temperature swings without warping.
Hauppauge sits right in the middle of Suffolk County’s weather patterns—you get hit with nor’easters, summer storms, and winter freezes that average 27-30 inches of snow annually. Your skylight needs to handle all of it without leaking or losing efficiency. That’s why we use materials rated for coastal conditions and install every component to manufacturer specifications.
You also get options. Need ventilation? Solar-powered Fresh Air skylights open automatically and meet ENERGY STAR guidelines. Want more light without the heat? Low-E glass blocks UV rays while keeping your rooms bright. We walk you through what makes sense for your space and your budget.
The work comes with a leak-free guarantee because we install it right the first time. No callbacks, no patch jobs, no crossing your fingers during the next storm. Just a skylight that works the way it should.
Most skylight replacement projects in Hauppauge run between $1,500 and $3,500 depending on skylight size, roof pitch, and whether there’s any underlying damage to address. That includes removing your old skylight, installing a new Velux unit with proper flashing, sealing everything for Long Island weather, and matching your existing roofing material around the opening.
New York sits in the high-cost labor tier, which means you’re typically looking at $3,300-$6,250 for more complex installations like larger units or flat roof skylights. But you’re also getting licensed contractors who know what coastal weather does to roofs and won’t cut corners on flashing or seals.
The real cost comes from not replacing a failing skylight. Water damage spreads fast once it starts, and repairing rotted decking or ceiling damage costs way more than a proactive replacement. If you’ve patched the same skylight multiple times in recent years, replacement usually delivers better long-term value than another temporary fix.
Most single skylight replacements take 4-6 hours from start to finish, and we typically complete the job in one day assuming decent weather. That includes removing your old skylight, inspecting and prepping the opening, installing the new unit with proper flashing, sealing everything, and matching your roofing material around it.
Larger projects or multiple skylights obviously take longer. If we find rotted decking or structural damage once we remove the old skylight, we address that before installing the new unit, which can add time. But we’re not leaving your roof open overnight—if weather rolls in or we hit unexpected issues, we secure everything properly before we leave.
The timeline also depends on product availability and scheduling. Velux skylights are usually in stock or available within a few days, but custom sizes or specialty glass can take longer to source. We give you realistic timeframes upfront so you can plan accordingly, and we don’t start tearing into your roof until we have everything we need to finish the job.
Most skylight leaks come from improper flashing installation, not the glass itself. Flashing is the metal barrier that directs water around your skylight instead of into your house. If it’s installed wrong, degraded, or wasn’t designed for your roof pitch, water finds a way in—especially during Long Island’s freeze-thaw cycles that stress seals beyond their limits.
The other common culprit is old, degraded seals around the skylight frame. Salt air from Long Island Sound accelerates deterioration, and temperature swings cause materials to expand and contract until they crack. Once that happens, every rainstorm is an opportunity for water to seep through.
We prevent leaks by installing step flashing around the sides and continuous flashing at the head and sill, all sealed with high-grade materials designed for coastal conditions. The new Velux skylights we install come with integrated flashing systems that work with your roof’s pitch and material. Everything’s installed to manufacturer specifications, which means proper overlap, correct fastener placement, and seals that handle Long Island weather without failing. That’s why we can offer a leak-free guarantee—because we’re not guessing or cutting corners on the install.
If your skylight is less than 10 years old and the leak is clearly from a single failed seal or minor flashing issue, repair might make sense. But if you’re dealing with an older skylight that’s been patched before, fogged glass, visible frame damage, or leaks you can’t pinpoint, replacement is usually the smarter move.
Here’s why: older skylights often have multiple problems developing at once. You might fix the obvious leak, but the seals are degraded, the frame’s corroding, and the glass has lost its insulating properties. You end up paying for repairs now and replacement later anyway. Plus, older plastic skylights can be up to 35% less energy efficient than modern Velux units, so you’re losing money on heating and cooling every month.
Long Island’s weather is particularly hard on skylights. If your unit has been through 15-20 winters of freeze-thaw cycles and countless coastal storms, the materials are fatigued even if they’re not actively leaking yet. Replacement gives you modern glass that doesn’t fog, frames that resist corrosion, and flashing systems designed for current building codes. You also get a warranty and the peace of mind that comes with knowing your roof is actually sealed properly.
Yes, we handle flat roof skylight installations throughout Hauppauge and Suffolk County. Flat roof skylights require different installation methods than pitched roofs—you’re typically working with curb-mounted units that sit on a raised frame to ensure proper water drainage and prevent pooling around the skylight.
The flashing and sealing process is more involved because water doesn’t naturally run off a flat surface the way it does on a pitched roof. We build or install a properly sized curb, flash it into your existing roof membrane, and seal everything with materials rated for flat roof applications. The skylight itself sits on top of the curb with additional weatherproofing to handle Long Island’s rain, snow, and ice.
Flat roof skylights also need to account for snow load, which matters in Hauppauge where you’re averaging 27-30 inches per winter. We make sure your roof structure can support the skylight and any snow accumulation without sagging or stressing the seals. The installation takes longer than a pitched roof skylight—usually a full day or more—but it’s done right so you don’t end up with leaks or drainage issues down the line.
Velux skylights cost more upfront, but they’re built for climates like Long Island’s and they last 20-25 years with minimal maintenance. Cheaper skylights often use thinner frames, lower-grade seals, and glass that fogs or yellows within a few years. You save money now and spend it later on repairs, replacements, or higher energy bills.
Velux units come with integrated flashing systems designed to work with your specific roof type and pitch. That matters because improper flashing is the main cause of skylight leaks, and generic skylights often require custom flashing that’s only as good as the installer’s experience. Velux takes the guesswork out of it, which is why we can confidently offer a leak-free guarantee when we install them.
You’re also getting better energy efficiency. Velux skylights meet ENERGY STAR guidelines and include Low-E glass options that block UV rays without blocking light. That means brighter rooms without the heat gain that makes your AC work overtime in summer. The monthly energy savings add up over the skylight’s lifespan, and you’re not dealing with condensation, fogging, or drafts that cheaper units develop as they age. For a roof component that needs to handle decades of coastal weather, Velux is the option that actually holds up.
