What does a skylight cost in New York?

Straight answer: here are real unit prices, from the current VELUX price list (effective August 17, 2026), with NYC sales tax included. Installation is separate — it depends on your roof, access, and interior finish, which is why every job gets a free on-site estimate. But unlike most of the industry, we'd rather show you real numbers than make you call for everything.

What moves the installed price: roof type and pitch, whether an existing curb can be reused, interior finish work, hoisting/access, and how many units go in at once (multiple-skylight discounts apply). A typical residential install is quoted in one free site visit — and every deck-mounted quote from us already includes the flashing kit, so compare other bids carefully.
How our prices compare: national averages for skylight replacement run $800–$2,400 installed — but the low end of that range is a bare acrylic dome. Our installed replacement price is a complete VELUX Skylight System: solar shade and remote included, NYC sales tax included, full-unit replacement — never a dome swap — backed by a 10-year No Leak Warranty. One number, nothing hiding at the bottom of the invoice.
