Your skylight shouldn’t be the weak point in your roof. If you’re dealing with leaks after every storm, fogged glass that blocks the light you installed it for, or condensation dripping onto your floors, you already know something’s wrong.
Most skylight problems come down to two things: age and installation. Skylights older than 15 years don’t have the seals, insulation, or flashing systems that modern units do. And even newer ones fail if they weren’t installed correctly in the first place.
When we replace a skylight, you’re not just swapping out glass. You’re getting a system that’s built for Long Island weather—proper flashing, insulated frames, double-pane glass, and seals that hold up against nor’easters and summer humidity. The result is a roof that stays dry, a home that stays comfortable, and energy bills that don’t spike every season.
We’ve been handling skylight replacements across Suffolk County for over 10 years. We’re not a national franchise or a crew that shows up once and disappears. We’re local, licensed, and insured—and we’ve worked on enough roofs in Mastic Beach to know what holds up and what doesn’t.
Coastal homes face different challenges than inland properties. Salt air, high winds, and freeze-thaw cycles all put extra stress on skylights. That’s why we use Velux products with integrated flashing systems and why we don’t cut corners on waterproofing. Every installation comes with a leak-free guarantee because we know how to do it right the first time.
You’ll work with the same crew from estimate to cleanup. No subcontractors, no surprises, no runaround when you call with a question.
We start with a roof inspection to assess the condition of your current skylight, the surrounding shingles, and the flashing system. If there’s rot or structural damage underneath, we’ll tell you upfront—not after we’ve already started tearing things apart.
Once you approve the estimate, we schedule the replacement around your timeline and the weather. On install day, we carefully remove the old skylight, inspect and repair the roof deck if needed, and install the new unit with fresh flashing and a complete waterproof seal. We match shingles, clean up all debris, and run a final water test to make sure everything’s sealed tight.
Most residential skylight replacements take one day. Larger projects or multi-unit installs may take longer, but we’ll give you a clear timeline before we start. After installation, you’ll get documentation on your warranty, care instructions, and our contact info if anything comes up down the road.

Every skylight replacement includes removal of the old unit, inspection and repair of the roof deck, installation of a new Velux skylight with integrated flashing, complete waterproof sealing, shingle matching and blending, interior and exterior cleanup, and a leak-free installation guarantee.
We handle both fixed and vented skylights, including solar-powered models with rain sensors that close automatically during storms. If you’re replacing a skylight on a flat roof or low-slope section, we use curb-mounted systems designed specifically for those applications—standard dome skylights don’t cut it in those situations.
Mastic Beach homeowners often ask about energy efficiency. Modern skylights with double-pane, low-E glass can reduce heat loss in winter and block UV rays in summer, which means lower energy bills and less fading on your furniture. If your current skylight is single-pane or has a broken seal, you’re losing conditioned air every day. Replacement pays for itself faster than most people expect, especially with older units that are drafty or fogged over.
Most residential skylight replacements in Mastic Beach run between $1,500 and $3,500 per unit, depending on size, type, and roof access. That includes the skylight itself, all flashing and sealing materials, labor, and cleanup.
Vented or solar-powered skylights cost more than fixed units. Larger sizes or custom dimensions also increase the price. If there’s roof deck damage underneath the old skylight, repair costs get added to the total—but we’ll identify that during the estimate so there are no surprises.
If you’re bundling skylight replacement with other roof work, the overall labor cost usually drops because the crew is already on site. We’ll walk through pricing options during the estimate and give you a written quote before any work starts.
If your skylight is leaking, fogged between the panes, cracked, or older than 15 years, replacement usually makes more sense than repair. Leaks often mean the flashing or seal has failed, and patching it is a temporary fix at best.
Fogged glass means the seal is broken and moisture is trapped inside. You can’t fix that without replacing the entire unit. Cracks in the glass or frame are also beyond repair—they’ll only get worse with temperature changes and weather exposure.
Skylights older than 15 years lack the energy efficiency and durability of modern units. Even if they’re not leaking yet, they’re costing you money in energy loss and they’re more likely to fail during the next big storm. Replacement gives you better insulation, stronger materials, and a warranty that actually protects you.
Velux skylights with double-pane, low-E glass and integrated flashing systems hold up best in Suffolk County. They’re built to handle temperature swings, high winds, heavy snow, and the salt air that comes with being this close to the water.
Vented models are popular because they improve airflow and reduce humidity, which is a big issue in coastal homes. Solar-powered versions with rain sensors are even better—they open and close automatically, so you don’t have to worry about forgetting to close them before a storm.
For flat or low-slope roofs, curb-mounted skylights are the only option that works long-term. Standard skylights sit flush with the roof and don’t drain properly on flat sections, which leads to leaks and ponding water. Curb-mounted units sit higher and channel water away from the opening.
Most single skylight replacements take four to six hours from start to finish. That includes removing the old unit, prepping the roof deck, installing the new skylight with flashing, sealing everything, and cleaning up.
If we’re replacing multiple skylights or dealing with roof deck damage, it may take a full day or slightly longer. Weather can also affect timing—we won’t install a skylight in the rain or when ice is present because proper sealing requires dry conditions.
We’ll give you a clear timeline during the estimate. Once we’re on site, we work efficiently and clean up completely before we leave. You’ll have a fully functional, watertight skylight by the end of the day.
If your skylight was damaged by a storm—cracked by hail, broken by a fallen branch, or torn up by high winds—your homeowner’s insurance will usually cover replacement. You’ll need to file a claim and have an adjuster inspect the damage.
Insurance typically won’t cover skylights that failed due to age or poor maintenance. If the seal just wore out over time or the flashing deteriorated on its own, that’s considered normal wear and tear.
We can work directly with your insurance company and provide documentation, photos, and a detailed estimate to support your claim. If the adjuster approves the replacement, we’ll coordinate timing and make sure the work meets all policy requirements.
Yes. Skylight replacement is a standard roofing procedure when done by experienced crews. We carefully remove shingles around the old skylight, pull the unit and flashing, inspect and repair the roof deck if needed, and install the new skylight with fresh flashing and sealing.
Once the new unit is in place, we reinstall shingles and blend them so the repair area matches the rest of your roof. If your shingles are discontinued or faded, we’ll source the closest match available or discuss options for blending the transition.
The key is proper flashing and sealing. That’s where most leaks start—not from the skylight itself, but from improper installation around it. We use integrated flashing systems that are designed to work with your specific roof pitch and shingle type, so water sheds correctly and nothing gets under the seal.
