Skylight Replacement Process Smithtown

Simple Process, Professional Results

We start with a thorough assessment of your existing skylight and roof structure. This isn’t just looking at the obvious problem—we check the flashing, examine the surrounding roof area, and identify what’s really causing the issues. Next, we carefully remove your old skylight and prepare the opening. We inspect the roof deck, replace any damaged materials, and ensure everything is structurally sound before the new skylight goes in. Installation is where experience matters most. We install new flashing systems, seal everything properly, and test the skylight before we consider the job complete. Your new Velux skylight gets positioned correctly, sealed against Long Island weather, and finished with interior work that looks professional.

Velux Skylight Replacement Smithtown

What You Get With Our Service

Every skylight replacement includes complete removal of your old unit, professional installation of your new Velux skylight, and proper flashing and sealing. We handle the interior finishing work too—drywall repairs, painting, and trim work so everything looks seamless. In Smithtown’s competitive housing market, where median home values hit $940K, quality improvements matter. Our skylight replacements use energy-efficient glass that helps with those rising summer temperatures we’re seeing more of on Long Island. Double-glazed, tempered glass that meets current building codes and actually reduces your energy costs. We also include our workmanship warranty and help you understand manufacturer warranties on your new Velux skylight. From flat roof installations to standard pitched roofs, we handle the technical details so you get natural light without the problems.

How much does skylight replacement cost in Smithtown, NY?

Skylight replacement in Smithtown typically ranges from $1,000 to $4,000, depending on the size, type, and complexity of your installation. This includes the Velux skylight unit, complete removal of your old skylight, professional installation, flashing, sealing, and interior finishing work. The cost varies based on your roof type, accessibility, and whether we need to repair any water damage from your old leaking skylight. We provide transparent, upfront pricing with no hidden fees. Most homeowners find that the energy savings and eliminated repair costs make the investment worthwhile within a few years.

How long does a skylight replacement take to complete?

Most skylight replacements in Smithtown are completed in one day. We arrive in the morning, remove your old skylight, install the new Velux unit with proper flashing and sealing, and complete the interior finishing work before we leave. Weather can affect timing—we won’t start a skylight replacement if rain is expected, because protecting your home is our priority. Complex installations or those requiring structural repairs might take two days, but we’ll explain the timeline during your estimate. We work efficiently to minimize disruption to your daily routine.

What makes Velux skylights better than other brands?

Velux skylights are the industry standard for good reason. They use double-glazed, tempered glass that meets current building codes and provides superior energy efficiency. The flashing systems are engineered specifically for Long Island’s weather conditions—heavy rains, snow loads, and temperature swings. Velux skylights also come with comprehensive warranties and replacement parts are readily available. Their energy-efficient glazing helps reduce both heating and cooling costs, which matters in Smithtown where we’re seeing more extreme temperatures. The build quality is consistently reliable, which means fewer callbacks and problems down the road.

Will a new skylight help reduce my energy bills?

Yes, properly installed energy-efficient skylights typically reduce energy costs in two ways. First, natural light reduces your need for artificial lighting during the day, lowering electricity usage. Second, modern Velux skylights with proper sealing eliminate the air leaks that force your HVAC system to work harder. Old, leaky skylights often cost homeowners hundreds of dollars annually in wasted energy. Your heating system works overtime in winter when warm air escapes, and your air conditioning battles hot air infiltration in summer. A new, properly sealed skylight stops these energy losses while providing the natural light benefits you want.

Do you guarantee your skylight installations won't leak?

Absolutely. We guarantee our installation workmanship and use proven techniques that prevent leaks. This includes proper flashing installation, correct sealing procedures, and ensuring your new skylight integrates perfectly with your existing roof system. Our guarantee covers our installation work, and Velux provides manufacturer warranties on their skylights. We’ve been installing skylights in Smithtown for over 10 years and understand what it takes to keep Long Island weather outside where it belongs. If you have any issues with our installation, we come back and make it right.

Can you replace skylights on flat roofs or unusual roof types?

Yes, we handle skylight replacement on flat roofs, low-slope roofs, and various roof materials including asphalt shingles, tile, and metal roofing. Each roof type requires specific techniques and flashing systems, which is why experience matters. Flat roof skylights need different mounting and drainage considerations compared to pitched roofs. We assess your specific roof structure and choose the appropriate Velux skylight model and installation method. Whether it’s a curb-mounted or deck-mounted installation, we have the expertise to ensure proper fit, sealing, and long-term performance on your Smithtown home.
