Commercial Skylight Replacement in Brooklyn, NY
Commercial skylight replacement is what BST Roofers handles when a dome is fogged, cracked, or letting water into your building, across offices, retail stores, warehouses, and multi-tenant properties in Brooklyn. We are licensed and insured, every replacement carries a warranty, and we can turn a quote around fast once we have seen the roof.
When an old skylight is telling you it is done
Skylights fail slowly, then all at once. These signs mean replacement, not another patch:
A cracked or fogged polycarbonate dome gone cloudy or brittle- Leaking around the curb that returns after sealant work
- Condensation trapped between panes, meaning the insulated glass unit has failed
- A corroded aluminum frame, or flashing pulling away from the roof
- Energy bills climbing because an old single-pane unit will not hold heat or cooling
Two mounting systems, two different jobs
Commercial skylights sit on a building one of two ways, and the replacement work follows the mounting type. Curb-mounted units sit on a structural curb with flashing tied into the surrounding roofing, common on pitched or stepped roofs. Flat roof and low-slope units, typical on warehouses and retail boxes, seal directly to the membrane instead. Getting that seal wrong is how a new skylight leaks within a year. If the roof deck itself is the problem, our commercial roofing replacement page covers a full roof replacement.

From inspection to a sealed, watertight finish
Every commercial skylight replacement follows the same sequence, whatever the building type.
Inspect the curb, frame, and surrounding roofing before quoting the work.
Remove the old unit and haul it off site the same visit.
Install the new energy efficient glazing, insulated glass or a polycarbonate dome, in an aluminum frame, with flashing integration and code-compliant safety glazing.
Seal the unit and pressure-check it for a watertight finish before leaving the roof.
Built around your hours, not ours
We plan rooftop access and removal around your business hours, whether you run an office, a restaurant, a school, a warehouse, or a church. Old unit removal and disposal happen in the same visit as the new install. A single-unit job typically closes the roof opening the same day it is opened, so the space below stays usable.
