Skylight Repair & Replacement on Long Island, NY
NovaLee Solutions repairs and replaces residential skylights across Suffolk County and Long Island, NY. Most leaking skylights are not the glass — they're the perimeter flashing, the rubber gasket, or the underlayment. We diagnose first, replace flashing kits or full units (most often Velux) with matched shingles, and back the work with a 10-year craftsmanship warranty.

Frequently asked questions
Why is my skylight leaking when the glass looks fine?
About 80% of skylight leaks on Long Island come from the perimeter flashing or the rubber gasket between the glass and the frame, not the glass itself. Both are repairable without replacing the whole unit.
Can you replace a skylight without replacing the roof?
Yes. We lift only the surrounding 3-4 feet of shingles, swap the unit and flashing kit, and re-shingle. The repair is invisible from inside.
Are solar-powered skylights worth it?
Velux solar-powered venting skylights (VSS, VCS) qualify for the 30% federal Residential Clean Energy Credit, which usually offsets the upgrade cost over a non-venting model. They're popular on bathrooms and stairwells.
What size and brand of skylight do you install?
We install Velux as our default — they are the most widely stocked on Long Island and have the best flashing kits. We can also install Wasco / VKR equivalents if that matches your existing opening.
Do you do skylights on flat roofs?
Yes — flat-roof curb-mounted units (Velux FCM with EDH flashing) are a separate scope from pitched-roof installs and are quoted individually.
