No more ceiling stains. No more buckets during rainstorms. No more wondering if this winter’s freeze-thaw cycle will finally crack the seal for good.
You get a skylight that’s actually sealed against Mattituck’s salt air and temperature swings. The kind that doesn’t fog up, doesn’t leak when snow melts, and doesn’t cost you an extra $15 every month in wasted heat. Most of our residential skylight replacement jobs finish in one day, and you’re covered with a leak-free guarantee that means something.
Your home stays dry. Your energy bills drop. And you stop thinking about your skylight entirely, which is exactly how it should be.
We’ve spent two decades replacing skylights across Suffolk County. We’ve seen which brands hold up to coastal weather and which ones fail in three years. We know what happens when flashing isn’t marine-grade or when installers skip the waterproof membrane on flat roofs.
Mattituck homeowners deal with conditions most contractors don’t understand. Salt air corrodes standard flashing faster. Temperature swings crack seals that work fine inland. Heavy snow sits longer on roofs this close to the water. We account for all of it because we’ve been working in these conditions since day one.
You’re not getting a crew that learned roofing in Arizona. You’re getting Suffolk County specialists who know exactly what your home needs.
We start with an inspection of your current skylight and the roof structure around it. Most leaks aren’t just the skylight itself – they’re failed flashing, cracked curbs, or water pooling where it shouldn’t. We identify the real problem before we quote you.
Once you approve the work, we remove your old skylight and check the framing. If there’s rot or damage from previous leaks, we fix it. Then we install your new Velux skylight with marine-grade flashing, multiple layers of waterproof membrane on flat roofs, and proper sloped insulation so water runs off instead of pooling.
The install usually takes four to six hours for a single skylight. We clean up completely, haul away the old unit, and walk you through the warranty. Most jobs finish in one day, weather permitting, and you’re covered against leaks from day one.

You’re getting a Velux skylight engineered for coastal climates. Double-pane insulated glass that cuts heat loss in winter and keeps your home cooler in summer. Factory-sealed units that don’t fog up or yellow after five years like cheaper plastic skylights do.
We install it with curb-mounted systems on flat roofs – reinforced mounting, custom flashing, and sloped insulation that prevents water from sitting. On pitched roofs, we use step flashing integrated with your shingles so there’s no gap for water to sneak through. Every seal gets marine-grade sealant that handles Mattituck’s salt air without corroding.
Mattituck’s housing stock is 96% single-family homes, and most are owner-occupied with median values over $1 million. Your home deserves an installation that protects that investment. We’re not cutting corners on materials or rushing the flashing work. The average skylight replacement here runs $2,000 to $5,000 depending on size and roof type, and that includes proper weatherproofing for Long Island’s freeze-thaw cycles and coastal storms.
If your skylight qualifies as energy-efficient, you can claim up to $600 in federal tax credits. We’ll provide documentation for your filing.
Most single skylight replacements take between four and six hours from start to finish. We typically complete the work in one day unless we’re dealing with structural damage from long-term leaks or weather delays.
The timeline depends on your roof type and what we find during removal. Flat roofs take longer because we’re building a curb-mounted system with multiple waterproofing layers. If your roof deck has rot or the framing needs reinforcement, that adds time. We won’t know for certain until we remove the old skylight, but we’ll tell you immediately if we find issues that extend the job.
We don’t leave your roof open overnight. If weather rolls in or we hit unexpected damage, we seal everything temporarily and come back to finish. You’re never left with a tarp and a prayer.
Coastal conditions are harder on skylights than inland climates. Salt air corrodes metal flashing faster, even if it’s galvanized. Temperature swings between winter and summer crack seals that would last ten years in a stable climate. Heavy storms off the Atlantic test every weak point twice as hard.
Mattituck gets 27 to 30 inches of snow annually, and that snow sits on your roof while temperatures swing above and below freezing. Water gets into tiny gaps, freezes, expands, and creates bigger openings. Do that a hundred times over one winter and your skylight starts leaking by spring.
Most skylight leaks happen because the original installation didn’t account for these conditions. Standard flashing fails. Cheap sealants crack. Plastic skylights warp. We use marine-grade materials and Velux skylights specifically because they’re engineered for climates like ours. It’s not overkill – it’s what actually works here.
If your skylight is more than 15 years old, replacement almost always makes more sense than repair. Older skylights lose energy efficiency even if they’re not leaking yet. The seals degrade, the glass fogs up, and you’re losing heat all winter.
Three out of four skylight leaks are caused by failures in the skylight itself, not just the flashing. You can reseal flashing and stop the leak temporarily, but if the skylight frame is cracked or the glass seal is broken, you’re just delaying the inevitable. Repairs typically cost $400 to $800, and replacement runs $2,000 to $5,000. If you’re spending $600 on a repair for a 20-year-old skylight, you’re throwing money away.
New Velux skylights are up to 35% more energy efficient than older models. That’s $10 to $15 monthly in savings, which means your replacement pays for itself over time. Plus you get a leak-free guarantee and modern features like rain sensors and solar-powered operation.
Velux skylights are engineered for temperature extremes and coastal moisture. They use double-pane insulated glass with low-E coatings that reduce heat transfer. The frames are reinforced to handle structural stress from snow loads and wind. The seals are designed for climates that freeze and thaw repeatedly.
After 20 years of installations across Suffolk County, we’ve seen which brands hold up and which ones don’t. Cheaper plastic skylights yellow and crack within five years here. Budget brands use flashing that corrodes in salt air. Velux costs more upfront, but you’re not replacing it again in ten years.
They also offer solar-powered models that open automatically for ventilation and close when rain sensors detect moisture. You’re not climbing up to manually close your skylight when a storm rolls in. For Mattituck homeowners with flat roofs or hard-to-reach installations, that’s a real advantage.
Modern skylights with double-pane insulated glass and proper installation can cut your energy waste significantly. Old single-pane or plastic skylights lose heat in winter and let heat in during summer. You’re essentially heating or cooling the outdoors.
Velux skylights with low-E glass can be up to 35% more energy efficient than older models. That translates to roughly $10 to $15 monthly in electricity savings for most homes. Over a 20-year lifespan, that’s $2,400 to $3,600 back in your pocket.
The bigger savings come from stopping air leaks. If your current skylight has gaps around the frame or cracked seals, you’re losing conditioned air constantly. Proper installation with marine-grade sealants and weatherproof flashing eliminates those leaks. Your HVAC system doesn’t work as hard, and your home stays more comfortable year-round. Plus energy-efficient skylights qualify for federal tax credits up to $600, which offsets some of your upfront cost.
Every skylight installation comes with our leak-free guarantee against water infiltration. If your skylight leaks because of our installation, we come back and fix it at no cost to you. That covers our workmanship, flashing installation, and waterproofing.
Velux skylights carry their own manufacturer warranty – typically 10 years on the skylight itself and 20 years on the glass seal. That’s separate from our installation warranty and covers defects in materials or manufacturing.
We’re a fully licensed and insured Suffolk County contractor. If something goes wrong during installation – roof damage, injury, property damage – our insurance covers it. You’re not taking on liability when we’re on your property. We’ve been serving Suffolk County for over a decade with a 5.0 rating on HomeAdvisor. Our warranty means something because we’re still here to honor it.
