No more water stains spreading across your ceiling. No more buckets on the floor during storms. No more wondering if that small drip is turning into rotted framing and moldy insulation behind your drywall.
A properly installed skylight replacement means your home stays dry when it rains. Your energy bills drop because modern skylights don’t leak heat in winter or let it pour in during summer. You get the natural light you wanted without the constant worry.
Most skylight leaks aren’t even caused by flashing problems. Three out of four come from the skylight itself—cracked glass, failed seals, or units that weren’t built for Suffolk County’s freeze-thaw cycles and coastal weather. That’s why resealing rarely works for more than a season or two.
When you replace a failing skylight with a Velux unit installed correctly, you’re done dealing with it. The right materials, the right installation, and a leak-free guarantee mean you can stop thinking about your roof every time it rains.
We’ve spent more than 10 years replacing skylights across Suffolk County. We’re licensed, insured, and we don’t use subcontractors. Every person on your roof is trained to our standards and knows how Long Island weather tests every seal and flashing detail.
Holtsville homeowners deal with specific challenges—humid summers, freeze-thaw cycles, nor’easters that test every weak point in your roof. Your median home value sits around $655,000, which means you’re not looking for the cheapest fix. You’re looking for the one that works.
We’ll tell you honestly whether your skylight needs repair or replacement. If a repair will actually hold up, we’ll say so. But if your skylight is over 15 years old or showing signs of seal failure, we’re not going to waste your time with a temporary patch that fails next winter.
First, we assess your current skylight to determine if you’re dealing with a flashing issue or skylight failure. Most leaks come from the unit itself, not the installation around it. If replacement makes sense, we’ll explain why and give you transparent pricing—typically between $800 and $2,500 per skylight depending on size and type.
Once you’re ready to move forward, we schedule installation on a clear-weather day. We protect your interior with tarps, remove the old skylight, and inspect the curb and surrounding roof structure for any water damage that needs addressing. Then we install your new Velux skylight with integrated flashing systems and multiple layers of waterproof membrane.
Most single skylight replacements take four to six hours. We complete the work in one day, weather permitting. You’re not left with an open hole in your roof overnight, and you’re not dealing with crews coming and going for weeks.
After installation, you get our leak-free guarantee backed by workmanship warranty, plus Velux’s material warranty. If a leak occurs within the warranty period, we come back and fix it at no charge. That’s not standard in this industry, but it should be.

Your skylight replacement includes removal of the old unit, inspection of the roof structure, and installation of a new Velux skylight with proper flashing designed for Suffolk County’s climate. We’re talking about double-pane glass that reduces heat loss in winter and keeps cooling costs down in summer—about 35% more efficient than older units.
You can choose from fixed skylights that don’t open, venting models that provide airflow, or solar-powered options with rain sensors that close automatically when moisture is detected. Flat roof applications get curb-mounted systems with reinforced mounting and custom flashing. Every installation includes integrated flashing systems that work with your existing roofing material.
In Holtsville, where temperatures are projected to increase and extreme heat days will double by the 2050s, energy efficiency isn’t just a nice feature. Modern skylights can save you $10 to $15 monthly on electricity bills. Over the 20-plus year lifespan of a quality skylight, that adds up.
We also handle storm damage response. If a nor’easter or hurricane damages your skylight, we can secure your home immediately and start repairs the same day. Suffolk County weather doesn’t wait, and neither do we.
Skylight replacement in Holtsville typically runs between $800 and $2,500 per skylight, depending on size, type, and roof complexity. A standard fixed skylight on an accessible pitched roof costs less than a large venting unit on a flat roof that requires custom curb mounting.
That price includes removal of your old skylight, new Velux unit, integrated flashing system, waterproof membrane installation, and labor. It doesn’t include repairs to water-damaged framing or drywall, which we assess during the initial inspection.
Material costs have increased about 10% from 2024 to 2025, and Velux typically raises prices each March. Waiting often means paying more, especially if your leak is causing interior damage that compounds monthly. A minor repair might cost $150 to $500 now, but delaying skylight replacement can lead to $3,000 to $10,000 in structural and interior damage.
We provide upfront pricing with no hidden fees. If you need financing, we offer options for qualified homeowners. You’ll know exactly what you’re paying before we start work.
If your skylight is over 15 years old and leaking, replacement usually makes more sense than repair. Here’s why: three out of four skylight leaks come from the skylight itself—cracked glass, failed seals, or manufacturing defects—not from flashing issues.
Resealing with caulk might stop the leak temporarily, but standard caulk breaks down in Suffolk County’s temperature extremes and UV exposure. You’ll be back on your roof in six months doing it again. Traditional repair approaches work about one time in four for older skylights.
If your skylight is newer and the leak is clearly coming from damaged flashing, repair might be the right call. We’ll inspect your situation and tell you honestly which approach makes sense. We’re not interested in selling you a replacement if a $300 repair will actually hold up.
But if you’re dealing with an older unit, failed seals, or visible condensation between panes, replacement stops the problem permanently. You get modern energy efficiency, a leak-free guarantee, and you’re done thinking about it for the next 20 years.
Most single skylight replacements take four to six hours and are completed in one day, weather permitting. We’re not leaving your roof open overnight or stretching a simple job across multiple days.
The timeline depends on a few factors. A standard skylight on an accessible pitched roof with no structural damage goes faster than a flat roof installation requiring custom curb work. If we discover rotted framing or damaged sheathing when we remove the old unit, that adds time for repairs.
We schedule installations on clear-weather days because we need dry conditions to properly install flashing and waterproof membranes. Suffolk County weather can be unpredictable, so we monitor forecasts closely and communicate any necessary schedule adjustments.
Multiple skylights obviously take longer—plan on a full day for two or three units. But even larger jobs are typically completed in one or two days. You won’t have crews showing up sporadically over weeks. We finish the work, clean up, and you’re back to your normal routine.
Yes, but the savings depend on what you’re replacing. Modern Velux skylights with double-pane glass can be 35% more energy efficient than older single-pane units. That typically translates to $10 to $15 monthly savings on electricity bills in Holtsville.
Older skylights leak heat in winter and let heat pour in during summer, forcing your HVAC system to work harder. If your current skylight has failed seals or condensation between panes, it’s basically a hole in your insulation. Replacing it with a properly installed modern unit stops that energy loss.
Over a 20-year lifespan, you’re looking at $2,400 to $3,600 in energy savings. That doesn’t fully offset the replacement cost, but it significantly reduces your net expense. And that’s before considering the value of not dealing with water damage, interior repairs, and the constant worry every time it rains.
Suffolk County is projected to see temperature increases of 3.8 to 5.8 degrees by the 2050s, with extreme heat days doubling. Energy-efficient skylights aren’t just about saving money now—they’re about keeping your home comfortable as summers get hotter.
Velux skylights are specifically engineered for challenging climates with integrated flashing systems that handle freeze-thaw cycles, coastal humidity, and the kind of weather Suffolk County throws at your roof. Not all skylights are built the same, and cheaper units fail faster in our conditions.
The integrated flashing system is key. Instead of relying on site-built flashing that depends entirely on installer skill, Velux units come with factory-designed flashing that works with your specific roof type. Multiple layers of waterproof membrane and proper drainage channels keep water moving away from the opening, even during nor’easters.
Double-pane glass with low-E coatings reduces heat transfer in both directions. You’re not losing warmth in winter or gaining unwanted heat in summer. The seals are designed to handle temperature swings without failing, which is critical when you’re dealing with 20-degree mornings and 60-degree afternoons in the same week.
Velux also backs their products with material warranties up to 10 years. Combined with our installation guarantee, you have real protection. We’ve seen too many budget skylights fail within five years because they weren’t built for Long Island’s coastal environment and salt air exposure.
Professional skylight replacement typically returns 50 to 60% of the project cost in increased home value, according to appraisers. In Holtsville, where the median home value is around $655,000, quality improvements matter to buyers who are making significant investments.
A leaking skylight is a red flag during home inspections. It signals potential water damage, structural issues, and deferred maintenance. Replacing it before selling eliminates that concern and shows you’ve maintained the property properly.
Beyond resale value, a properly functioning skylight improves your daily living experience. More natural light makes spaces feel larger and more inviting. Lower energy bills mean more money in your pocket each month. No water damage means no expensive emergency repairs.
If you’re planning to stay in your home, the value isn’t just financial. It’s about not worrying every time it rains. It’s about a ceiling that stays dry and a home that feels brighter. Those benefits start the day we finish installation and continue for decades.
