You’ll notice the difference immediately. Natural light floods rooms that used to feel cramped and dark—up to five times more light than a standard window of the same size.
Your heating and cooling costs drop. Modern ENERGY STAR certified skylights can cut your energy bills by up to 13%, and if you’re replacing an old plastic skylight from the ’80s or ’90s, you might see even bigger savings. That’s real money back in your pocket every month.
No more water stains on your ceiling. No more scrambling for buckets when it rains. A properly installed skylight with the right flashing system keeps water where it belongs—outside. You protect your insulation, your drywall, and everything else that water damage quietly destroys over time.
And if you’re thinking about selling, buyers notice skylights. In Lake Ronkonkoma’s $640,000+ housing market, the right upgrades matter. Natural light sells homes.
We know Lake Ronkonkoma homes because we’ve been working on them since before the housing boom. We understand what freeze-thaw cycles do to roof penetrations. We know how Long Island humidity tests every seal and flashing detail.
Most skylight leaks aren’t the skylight’s fault—they’re installation problems. Poor flashing. Shortcuts around the roofing membrane. We’ve fixed enough bad installs to know exactly what goes wrong and how to prevent it.
We’re licensed, insured, and we use materials that actually match our climate. When we install a VELUX skylight, it comes with real warranties and engineering designed for New York winters. You’re not getting the cheapest option—you’re getting the one that won’t need replacing again in five years.
First, we come out and actually look at what you’ve got. Not every skylight needs full replacement—sometimes it’s a flashing issue or a seal that’s failed. But if the unit itself is old, fogged between panes, or cracked, replacement makes more sense than throwing money at repairs.
Once we know what you need, we walk you through your options. Size, ventilation, glass type, solar-powered vs manual operation. We’re not upselling you—we’re making sure you understand what you’re getting and why it matters for your specific roof and room.
Installation day, we protect your interior space first. Then we carefully remove the old skylight and inspect the roof deck and framing. If there’s hidden water damage, you’ll know about it before we go further. We install the new skylight with a complete flashing system—this is where most contractors cut corners and where most leaks start. Every layer gets sealed properly for Long Island weather.
After the skylight is in and we’ve cleaned up, we walk you through how it operates and what to expect. You get warranty information for both the product and our installation work. Then we’re done—and you’ve got a skylight that actually works.
Ready to get started?
You’re getting the full skylight unit—not just the glass, but the frame, flashing kit, and all the components engineered to work together. We typically install VELUX skylights because they’re built for our climate and they back up their product with actual warranties.
The installation includes removing your old skylight, inspecting and repairing any roof deck damage we find, installing the new unit with a complete waterproof flashing system, and integrating everything with your existing roofing material. If you’ve got asphalt shingles (like most Lake Ronkonkoma homes built between 1940-1999), we make sure the shingle layers tie into the flashing correctly.
You’ll also get interior finishing work—new trim if needed, drywall repair if the old skylight leaked, and paint touch-ups to match your ceiling. We don’t leave you with a working skylight and a mess around it.
For homes in Suffolk County, we’re dealing with temperature swings, coastal humidity, and occasional nor’easters. Your installation accounts for all of that. The flashing system we use is designed for freeze-thaw cycles. The seals are rated for high winds. This isn’t a California install dropped into New York—it’s engineered for what your roof actually faces.
Most residential skylight replacement projects run between $1,500 and $3,000 per skylight, including the unit and professional installation. That’s not a small expense, but it’s the right range for quality work that lasts.
The price depends on skylight size, whether you want ventilating or fixed, the roof pitch and accessibility, and whether we’re dealing with any existing damage. A standard 2×4 foot fixed skylight on an accessible roof costs less than a 4×4 venting unit on a steep pitch with rotted decking underneath.
Cheaper quotes usually mean cheaper materials or shortcuts on flashing. You’ll pay for that later in leaks and energy loss. Higher quotes might include premium features like solar-powered operation or impact-resistant glass—worth it if you want those features, but not necessary for everyone. We price based on what your specific situation actually requires, not what we can upsell you into.
If your skylight is less than ten years old and the leak is clearly a flashing issue, repair makes sense. If the skylight itself is fogged, cracked, or older than 15 years, replacement is usually the smarter move.
Here’s why: older skylights, especially the plastic dome types from the ’80s and ’90s, lose their seal over time. The plastic yellows and becomes brittle. Even if you fix the leak, you’re still losing energy through outdated glazing. You’re also likely to face another problem in a year or two.
Modern skylights are dramatically more efficient. If you’re heating and cooling a Lake Ronkonkoma home with a median value over $640,000, the energy savings from a new ENERGY STAR skylight add up quickly. You’re also getting better UV protection, clearer views, and warranties that actually mean something. Sometimes the “cheaper” repair costs you more in the long run.
Most single skylight replacements take one day, weather permitting. We’re usually done in 4-6 hours for a straightforward job.
That timeline assumes we’re replacing an existing skylight with a similar-sized unit and there’s no major damage to repair. If we find rotted decking or framing issues once we open things up, that adds time. If you’re replacing multiple skylights or dealing with a complicated roof layout, it might stretch into a second day.
We don’t rush the flashing work—that’s where leaks come from. Every layer gets installed in the right order with proper overlap and sealing. We’d rather take an extra hour to do it right than save 30 minutes and have you calling us back when it rains. Long Island weather is too demanding for shortcuts.
Not if it’s installed correctly. Most skylight leaks are installation problems, not product failures.
The flashing system is everything. Your skylight needs multiple layers of protection—the flashing kit that comes with the unit, proper integration with your roof’s water barrier, and correct shingle placement around the curb. Each layer has to overlap the one below it so water always has a path down and out. Miss one detail and water finds its way in.
We see this constantly with DIY installs and low-bid contractors. They skip steps or use the wrong materials for Long Island’s climate. Then homeowners think skylights just leak—but they don’t when they’re done right. VELUX skylights, installed with their complete flashing system and proper technique, have excellent track records. We back our installation work with warranties because we know it’s not going to leak.
VELUX skylights with laminated or tempered glass, proper flashing kits, and insulated frames. They’re engineered for climates like ours—cold winters, humid summers, and everything in between.
You want laminated glass for impact resistance (falling branches, hail) and Low-E coating for energy efficiency. Double-pane at minimum, triple-pane if the room gets extreme temperature swings. The frame should be vinyl-clad wood or foam-insulated to prevent condensation—aluminum frames sweat in our humidity.
Ventilating models help with moisture control, especially in bathrooms or kitchens. Solar-powered venting skylights will close automatically when rain sensors detect moisture, which is useful if you’re not home during a storm. Fixed skylights cost less and work fine for rooms where you just want light, not airflow. Either way, the flashing kit matters more than any other feature—that’s what keeps Long Island weather outside where it belongs.
Yes, if the existing skylight hasn’t already caused damage. We protect your interior space before we start work on the roof.
We use drop cloths and plastic sheeting to contain dust and debris. The actual skylight removal happens from the exterior, so we’re not tearing into your ceiling unless there’s existing water damage that needs repair. If your old skylight leaked, there might be drywall or insulation damage we need to address—but you’d want that fixed anyway.
Once the new skylight is installed, we handle interior trim work to finish everything cleanly. If there’s minor drywall repair needed, we take care of it. You’re not left with a functioning skylight and a torn-up ceiling. The goal is a complete job—exterior and interior—so you don’t need to hire someone else to finish what we started.
