Overstock Skylights & Roof Glazing

Skylights and sloped glazing go surplus when a roof detail changes or a curb gets built to the wrong dimension. Overhead glazing carries code requirements that vertical glazing doesn't, so the makeup matters more here than almost anywhere else.

Inventory in this category moves quickly, and a lot of it never gets listed at all — it sits in a yard until someone asks. Tell us what you need and we'll put it in front of contractors holding overstock.

What shows up in skylights & roof glazing

  • Curb-mount and deck-mount unit skylights, fixed and venting
  • Multiwall and corrugated polycarbonate panels
  • Translucent sandwich panel systems from daylighting work
  • Sloped glazing framing and rafters from atrium and canopy projects
  • Flashing kits, curbs, and condensation gutter components

Before you buy

Surplus is only a bargain if it fits and it's documented. These are the questions worth asking on this category specifically.

  • Overhead glazing generally requires laminated glass or a screened assembly so it can't fall as fragments — confirm the makeup satisfies your code
  • Curb-mount and deck-mount units are not interchangeable; match the unit to the curb you have or plan to build
  • Confirm the curb's outside dimension against the unit, since skylight sizing conventions vary by manufacturer
  • Ask whether the flashing kit is included and whether it suits your roof type and pitch
  • Verify the minimum slope the unit is rated for; some units cannot be installed below a stated pitch
  • Check polycarbonate for UV-layer orientation — it's directional, and installing it inverted causes rapid yellowing and embrittlement

Common questions

Does overhead glazing have to be laminated?

In most cases the inboard lite of sloped or overhead glazing must be laminated, or the assembly must include a screen below it, so that a break can't drop glass on occupants. Fully tempered glass alone is generally not acceptable overhead. Confirm the requirement in your adopted code before buying.

Can I install a curb-mount skylight directly on the deck?

No. Curb-mount units are designed to sit on a built curb that establishes the flashing height and water management. Deck-mount units integrate their own flashing. Substituting one for the other creates a leak you'll be back to fix.
