Residential Skylight Replacement Smithtown

What You Get When It's Done Right

You stop worrying every time it rains. No more ceiling stains, no more buckets in the attic, no more wondering if this storm will be the one that finally causes real damage.

Your energy bills drop because modern skylights with Low-E glass actually insulate instead of bleeding heat in winter and baking your home in summer. We’re talking 25% annual energy savings on average, sometimes more depending on how old your current skylight is.

The rooms feel different too. Brighter during the day, which means you’re not flipping lights on at noon. And if you’ve been living with foggy, yellowed plastic skylights, the clarity of new glass changes how the whole space feels.

Most single skylight replacements take us four to six hours. We protect your interior, handle the roof work properly, and you’re done in a day. No week-long projects, no endless disruption.

Smithtown Skylight Replacement Company

We've Been Fixing Roofs Here for Years

We’ve been handling residential skylight replacement across Suffolk County for over a decade. We’re licensed, insured, and local, which means we know exactly what Long Island weather does to skylights and how to install them so they last.

Smithtown homes deal with heavy snow loads, freeze-thaw cycles that crack seals, and coastal humidity that accelerates wear on older units. We’ve replaced hundreds of skylights in this area, and we’ve seen what fails and what holds up.

You’ll work with the same crew from start to finish. No subcontractors, no runaround. Just straightforward communication, transparent pricing before we start, and installation done right the first time.

Our Skylight Replacement Process

Here's Exactly What Happens During Your Job

First, we come out for a free inspection. We’ll get on the roof, check the flashing, look at the seal, and assess whether you need a full replacement or if a repair makes sense. For skylights over 15 years old, replacement usually makes more financial sense because seals, hardware, and energy efficiency are all compromised.

If you move forward, we schedule the work around weather. We protect your interior with tarps and prep the area. Then we remove the old skylight carefully, inspect the roof deck for any water damage, and make repairs if needed.

The new skylight goes in with proper flashing, which is where most leaks actually start. We use integrated flashing systems and multiple waterproof barriers designed for flat or pitched roofs depending on your home. Every seam gets sealed with high-grade materials that handle Suffolk County’s temperature swings.

Once it’s installed, we test it, clean up completely, and walk you through the warranty. Most jobs wrap in one day unless we find underlying roof damage that needs attention.

Velux Skylight Installation Smithtown

What's Included in Your Skylight Replacement

We install Velux skylights because they’re engineered for this climate and backed by real warranties. You’re getting double-pane glass that reduces heat loss in winter and keeps your home cooler in summer, plus integrated flashing systems that prevent the leaks caused by improper installation.

Every replacement includes removal of your old skylight, inspection and repair of the roof deck if there’s water damage, new flashing and waterproof sealing, and the new skylight unit with proper insulation. If you’re on a flat roof, we use curb-mounted systems with multiple layers of waterproof membrane and sloped insulation to direct water away from the skylight.

Smithtown sees 27 to 30 inches of snow annually, and temperatures hover around freezing during winter, which creates repeated freeze-thaw cycles. That’s why we don’t cut corners on flashing or sealing. Water gets into small gaps, freezes, expands, and creates bigger openings. Proper installation prevents that cycle from starting.

You’ll also get a transparent estimate upfront. Skylight replacement typically runs $800 to $2,500 per unit depending on size, roof type, and whether we’re dealing with flat or pitched installation. We offer financing for qualified homeowners if the cost needs to be spread out.

How do I know if I need skylight replacement or just a repair?

If your skylight is over 15 years old, replacement almost always makes more sense than repair. Here’s why: the seals are degraded, the hardware is worn, and you’re missing out on the energy efficiency of modern units. Repairing an old skylight is like patching an old tire repeatedly—you’re just delaying the inevitable.

For newer skylights, we can sometimes replace just the glass if the frame is structurally sound and the flashing is still good. But most leaks don’t come from the skylight itself. They come from improper flashing installation or degraded sealants around the unit.

During your free inspection, we’ll tell you honestly what makes the most financial sense. If a repair will actually solve the problem long-term, we’ll say so. But if you’re going to be calling us back in two years because the underlying issue wasn’t addressed, we’d rather replace it now and be done with it.

Most skylight leaks happen because of improper flashing installation, not because the skylight itself is bad. Flashing is the metal or waterproof material that seals the gap between your skylight and the roof. If it’s not installed correctly, water finds a way in.

In Suffolk County, freeze-thaw cycles make this worse. Water gets into small gaps, freezes overnight, expands, and creates larger openings. By spring, what started as a minor seal issue has turned into a full leak that shows up as ceiling stains or dripping water.

Ice dams are another common culprit on Long Island. When temperatures hover around freezing, snow melts during the day and refreezes at night, creating a dam that pushes water under shingles and around skylights. If your flashing wasn’t installed with this in mind, you’ll get leaks every winter. Proper installation with step flashing, continuous flashing at the head and sill, and multiple waterproof barriers prevents this.

Skylight replacement in Smithtown typically costs between $800 and $2,500 per skylight, including removal, installation, flashing, and materials. The price depends on the size of the skylight, whether it’s on a flat or pitched roof, and if there’s any underlying roof damage that needs repair.

Flat roof skylights cost more because they require curb-mounted systems, multiple layers of waterproof membrane, and sloped insulation to prevent water pooling. Pitched roof installations are more straightforward but still require proper flashing and sealing to handle Long Island weather.

We give you an upfront estimate before starting any work, so you know exactly what you’re paying for. No surprises, no hidden fees. And if the cost needs to be spread out, we offer financing options for qualified homeowners. Most people find that the energy savings and the peace of mind during storms make it worth the investment, especially when you factor in what water damage repairs would cost if you keep delaying.

Velux skylights are engineered to last and perform in climates like Long Island’s. After decades of installations across Suffolk County, the performance difference is obvious. Velux units hold up to nor’easters, handle freeze-thaw cycles without developing leaks, and continue to perform efficiently year after year.

Cheaper skylights often use single-pane glass or lower-grade plastic that yellows and fogs over time. They lack proper insulation, which means you’re losing heat in winter and gaining it in summer. The flashing systems are often generic and don’t integrate well with the skylight itself, which is where leaks start.

Velux skylights come with integrated flashing systems designed specifically for each unit, double-pane Low-E glass that reduces energy loss by up to 35% compared to older plastic skylights, and real warranties that actually mean something. You’re also getting features like solar-powered operation on some models, built-in blinds, and impact-resistant glass. When you’re making a long-term investment in your Smithtown home, reliability matters more than saving a few hundred dollars upfront.

Most single skylight replacements take four to six hours depending on roof type and access. We typically complete the job in one day, weather permitting. If we’re replacing multiple skylights or dealing with roof damage that needs repair, it might extend to a second day.

We start by protecting your interior with tarps so nothing gets damaged. Then we remove the old skylight, inspect the roof deck, and make any necessary repairs before installing the new unit. The actual installation includes proper flashing, waterproof sealing, and testing to make sure everything is secure.

Flat roof skylights take a bit longer because they require curb-mounted systems and more complex waterproofing. Pitched roof installations are faster but still require attention to detail on the flashing. Either way, we work efficiently to minimize disruption to your day. You won’t have a tarp on your roof for weeks or a crew showing up sporadically. We schedule the work, show up on time, and finish the job.

Yes, if your current skylight is old or improperly sealed. Modern energy-efficient skylights with Low-E glass and proper insulation can reduce your energy costs by up to 25% annually, which typically translates to $10 to $15 per month in savings depending on your home’s size and how many skylights you have.

Old plastic skylights or single-pane glass units bleed heat in winter and turn your home into a greenhouse in summer. You end up running your heating and cooling systems harder to compensate, which drives up your bills. New Velux skylights with double-pane glass and proper sealing reduce heat transfer significantly.

You’ll also use less artificial lighting during the day because modern skylights provide better, clearer natural light. That might not sound like much, but it adds up over time. And if you’re planning to sell your Smithtown home eventually, energy-efficient upgrades like new skylights appeal to buyers. Suffolk County’s median home values exceed $650,000, and buyers actively look for homes with energy-efficient features that will save them money long-term.
