Your Mount Sinai home gets more natural light than you thought possible. Skylights bring up to five times more illumination than regular windows, cutting your electric bills while making rooms feel larger and more inviting.
You get the privacy regular windows can’t offer. Roof-mounted skylights face the sky, not your neighbors’ windows.
And when summer heat builds up in your kitchen or bathroom, operable skylights let hot air escape naturally. No more fighting with stuffy rooms or running fans all day.
Expressway Roofing and Chimney has installed and repaired skylights across Suffolk County for over 20 years. We’ve seen what happens when skylights are installed wrong – the leaks, the damage, the headaches.
That’s why we guarantee leak-free results on every installation. We use proper flashing techniques, quality VELUX products, and the installation methods that actually work in Long Island’s weather.
Mount Sinai homeowners know they can call us 24/7 when problems arise. We’ve built our reputation on being there when you need us most, not just when it’s convenient.
We start with a free, no-obligation assessment of your roof and interior space. Our technician measures the area, checks the roof structure, and explains your options – fixed skylights, vented units, or sun tunnels.
Next comes precise installation. We cut the roof opening to exact specifications, install waterproof flashing, and secure your new skylight with proper sealing techniques. Every step is designed to prevent the leaks that plague poorly installed skylights.
Interior finishing comes last. We handle drywall repairs, trim work, and even paint touch-ups if needed. You get a complete installation from start to finish, not a half-done job that leaves you calling other contractors.

We install VELUX skylights because they’re built to last in Long Island’s climate. These aren’t the cheap plastic skylights that crack and leak after a few years.
Your options include fixed skylights for maximum light, vented skylights for airflow, and solar-powered units that open and close automatically. Sun tunnels work perfectly for smaller spaces like bathrooms and closets.
Mount Sinai’s coastal weather demands proper installation. We use stainless steel flashing, marine-grade sealants, and installation techniques proven to handle Long Island’s storms, salt air, and temperature swings. Most skylight problems happen because someone cut corners during installation – we don’t.
Standard skylight installation in Mount Sinai typically ranges from $1,000 to $3,000, depending on the size and type of skylight you choose. Fixed skylights cost less than vented or solar-powered units.
The total price includes the skylight itself, professional installation, flashing, interior finishing work, and our leak-free guarantee. Larger skylights or premium VELUX models cost more, but they also provide better energy efficiency and longer lifespan.
We provide free estimates so you know exactly what your project will cost before we start. No surprises, no hidden fees.
Most skylight leaks happen because of poor installation, not defective skylights. Damaged flashing, improper sealing, or incorrect positioning causes water to find its way inside.
We prevent leaks by using proper flashing techniques around the entire skylight perimeter. Our marine-grade sealants handle Long Island’s weather extremes, and we position each skylight to shed water naturally.
Age can also cause leaks when seals become brittle and crack. That’s why we recommend replacing skylights that are 20+ years old when you get a new roof – you want both to last the same amount of time.
Yes, but flat roof skylights require different products and installation techniques than pitched roof skylights. We see problems when contractors try to use the wrong type of skylight for the roof style.
Flat roof skylights need curb-mounted units that sit above the roof surface to shed water properly. The flashing system is completely different from deck-mounted skylights used on sloped roofs.
We stock both types and know which one your roof needs. Using the wrong skylight type is a guaranteed way to get leaks, even with perfect installation.
VELUX skylights typically last 20-30 years in Long Island’s climate when properly installed and maintained. The glass itself rarely fails – most problems come from flashing or seal deterioration over time.
Long Island’s salt air, temperature swings, and storm exposure can accelerate wear on lower-quality skylights. VELUX units are built specifically for coastal climates like ours.
Regular inspection every few years helps catch small issues before they become expensive problems. We offer maintenance services to keep your skylights performing properly throughout their lifespan.
Yes, professionally installed skylights typically increase home value because buyers prefer houses with natural light. The key word is “professionally” – buyers worry about water damage from poorly installed skylights.
Skylights make rooms feel larger and more open, which appeals to potential buyers. They also demonstrate that you’ve invested in energy-efficient improvements that reduce electric bills.
The return on investment is best when skylights are installed by experienced contractors who can provide documentation of proper installation. DIY or cheap installations can actually hurt resale value.
Skylights are actual windows in your roof that provide direct views of the sky. Sun tunnels are reflective tubes that capture light on the roof and channel it down to interior spaces through a ceiling-mounted diffuser.
Sun tunnels work great for bathrooms, closets, or hallways where you want light but don’t need a view. They’re also easier to install in tight spaces or when roof framing makes traditional skylights difficult.
Both options reduce your need for electric lighting during the day. The choice depends on whether you want the view and ventilation that skylights provide, or just the light that sun tunnels deliver.
