What You Get When Your Skylight Actually Works

No more water stains spreading across your ceiling. No more wondering if the next storm will turn your living room into a leak zone. When your skylight is installed correctly with proper flashing and modern materials, you stop worrying about it.

You’ll notice the difference on your energy bills too. Old skylights with single-pane glass and worn seals let heat escape in winter and turn rooms into ovens in summer. Modern double-pane units with Low-E coatings can cut your heating and cooling costs by up to 13%—real savings that add up month after month in Suffolk County’s extreme weather.

The light quality changes everything. Fogged, yellowed glass makes rooms feel dim and closed in. Clear, new glass brings in natural light that makes spaces feel bigger and more comfortable. You’re not just fixing a problem—you’re improving how you live in your home every single day.

Skylight Replacement Company Centereach

We've Been Doing This for 20 Years

Home Team Construction has spent two decades installing and replacing skylights across Long Island. We’ve seen which brands hold up to coastal moisture and freeze-thaw cycles, and which ones fail within five years. That experience matters when you’re making a decision that affects your home for the next 20 years.

We’re licensed and insured, and we handle everything from emergency storm repairs to complete roof skylight replacement. Most of our work comes from referrals—homeowners in Centereach and throughout Suffolk County who tell their neighbors about installations that don’t leak.

When you’re dealing with a hole in your roof, you want someone who understands how flashing integrates with your specific roof type, how to handle condensation in Long Island’s humid summers, and how to install units that won’t fail when snow piles up in January. That’s what we do.

Our Roof Skylight Replacement Process

Here's What Happens from Start to Finish

We start with an inspection to figure out what’s actually wrong. Sometimes you need a full replacement. Sometimes the flashing failed but the skylight itself is fine. We’ll tell you what you’re dealing with and give you an upfront price—no surprises later.

Once you’re ready to move forward, most single skylight replacements take 4-6 hours and get done in one day, weather permitting. We remove the old unit, inspect and repair any roof deck damage, install new flashing that integrates properly with your roofing material, and set the new skylight with proper sealing and waterproofing.

We use Velux skylights for most residential skylight replacement jobs because they’re engineered for climates like ours—double-pane insulated glass, integrated flashing systems, and hardware that doesn’t corrode in coastal air. After installation, we test everything, clean up completely, and walk you through the warranty coverage. You get documentation of the work and direct contact info if you ever have questions.

Home Skylight Replacement in Suffolk County

What's Included in Your Skylight Replacement

You get a complete removal of your old skylight and proper disposal of all materials. We inspect your roof deck for any water damage or rot that needs repair before the new unit goes in—this step matters because hidden damage will cause problems later if it’s not addressed now.

The new installation includes manufacturer-specified flashing designed for your roof type, whether that’s asphalt shingle, metal, or flat roofing. Flashing is where most skylight leaks start, so we don’t cut corners here. You get a fully insulated, double-pane skylight with Low-E coating that blocks UV rays and reduces heat transfer.

Every home skylight replacement comes with our leak-free installation guarantee and the manufacturer’s warranty on the unit itself. In Suffolk County, where we average 27-30 inches of snow annually and deal with freeze-thaw cycles that expand and contract materials, proper installation isn’t optional—it’s the difference between a skylight that lasts 20+ years and one that fails in five. We also handle any necessary interior finishing around the skylight opening, so you’re not left with exposed drywall or trim work to coordinate with another contractor.

How much does skylight replacement cost in Centereach, NY?

Most residential skylight replacement projects in Centereach run between $800 and $2,500 per skylight, depending on size, roof accessibility, and whether there’s any underlying damage that needs repair. A standard 2×4 foot skylight on an accessible asphalt shingle roof typically falls in the $1,200-$1,800 range for a quality Velux unit with proper installation.

Flat roof skylights or units on steep-pitch roofs cost more because they require more labor and specialized flashing systems. If we find rotted roof decking or damaged rafters during removal, that repair work adds to the cost—but it’s not optional if you want an installation that won’t leak.

We give you an upfront price after inspecting your specific situation. No hidden fees, no surprise charges when the job’s done. We also offer financing options for qualified homeowners, because we know that $2,000 isn’t always sitting in your checking account when your skylight starts leaking.

If your skylight is less than 10 years old and the leak is coming from damaged flashing or a broken seal that can be fixed, repair might make sense. But if your unit is 15+ years old, has fogged glass, shows cracks, or has failed multiple times, replacement is the smarter move.

Here’s why: older skylights lack the energy efficiency features that modern units have. You’re losing money every month on heating and cooling costs. The glass technology, insulation, and sealing methods have improved dramatically in the last 15 years. A new skylight will pay for itself over time through lower energy bills.

Also, if your skylight has leaked before and been “repaired,” there’s likely hidden water damage in your roof deck or framing that will cause problems down the road. When we replace the unit, we can inspect and fix that damage properly. Repeated repairs on an old skylight often end up costing more than replacement would have—and you still have an outdated unit that will fail again.

Most single skylight window replacement jobs take between 4-6 hours and get completed in one day, assuming decent weather and no major surprises when we open up the roof. We schedule the work when the forecast is clear because we’re not leaving your roof open overnight.

If we discover significant rot or structural damage that needs repair, that can add a few hours or require a second day. We’ll let you know right away if that’s the case and what it means for timing and cost.

Multiple skylights obviously take longer—figure a full day for two or three units. Flat roof skylights take more time than sloped roof installations because the flashing and waterproofing requirements are more complex. We’re not rushing through your job to get to the next one. We’re making sure it’s done right so you don’t call us back in six months with a leak.

Yes, if you’re replacing an old single-pane or poorly sealed skylight with a modern double-pane Low-E unit. Studies show that energy-efficient skylights can reduce heating and cooling costs by up to 13%. In Suffolk County where energy costs keep climbing, that’s real money—potentially $15-30 per month depending on your home size and how many skylights you have.

Old skylights are basically holes in your insulation. Single-pane glass offers almost no thermal protection. Worn seals let air leak in and out. In winter, you’re heating the outdoors. In summer, you’re air conditioning it. Modern Velux skylights use insulated glass with Low-E coatings that reflect heat back into your home in winter and block solar heat gain in summer.

The payback period varies, but if you’re replacing a 20-year-old skylight that leaks air, you’ll likely recoup the installation cost through energy savings within 7-10 years. And that doesn’t account for avoiding the cost of water damage repairs from leaks or the increased home value from having properly functioning, modern skylights.

We install Velux skylights for most residential projects because after 20 years of installations across Long Island, they’re the brand that consistently holds up to our climate. Suffolk County’s coastal moisture, freeze-thaw cycles, and heavy snow loads are tough on skylights. Velux units are engineered for exactly these conditions.

Their integrated flashing systems are designed to work with specific roof types and actually shed water properly. The hardware doesn’t corrode in salt air. The seals don’t fail after five years. The glass technology—double-pane with Low-E coatings and argon gas fill—provides real insulation value.

We’ve seen cheaper brands fail within 5-7 years, usually from flashing problems or seal failures. When you’re cutting a hole in your roof, the brand matters. Velux offers solid warranties and their products are available locally, which matters if you ever need parts or service. We’re not locked into one brand if your situation calls for something different, but nine times out of ten, Velux is the right choice for Long Island homes.

Yes. Storm damage is one of the most common reasons homeowners in Centereach call us for emergency skylight repair or replacement. Long Island’s winter storms dump heavy snow that creates ice dams, and our coastal weather brings wind-driven rain that finds every weak point in old flashing.

If your skylight started leaking after a storm, we can usually get out within a few days to assess the damage and provide temporary weatherproofing if needed. Sometimes the skylight itself is fine but the flashing got damaged or lifted. Other times the unit cracked from ice buildup or impact damage.

We’ll inspect everything, document the damage for insurance purposes if that’s relevant, and give you options for repair versus replacement. If the unit is old and this is just the final straw, replacement usually makes more sense than sinking money into repairs on a skylight that’s near the end of its lifespan anyway. We work with homeowners and insurance companies regularly on storm damage claims, so we know what documentation you’ll need and how to handle that process.
