What Is a Curb Mounted* Skylight?
A curb is simply a wooden box that is built higher than the roof and flashed (sealed) to become part of the roof.
The skylight is then dropped over the curb—much like the lid of a shoe box—and attached from the outside.
*Required for roof slopes LESS than 3/12 (14°).
What Is Skylight Flashing?
VELUX EDL Fl. Kit
Flashing is usually comprised of shaped metal in three components:
- Head flashing—at the top of the skylight.
- Sill flashing—at the bottom of the skylight.
- Step flashing—interwoven with the shingles along the sides of the skylight.
Flashing seals the skylight against the harshest extremes of weather and makes either a deck mount skylight or a skylight curb part of the roof itself.
What Is a Deck Mounted Skylight?

A deck mount skylight—unlike a curb mount skylight—is simply attached directly to the roof deck.
The skylight is then flashed (sealed) to become part of the roof.
A VELUX skylight installed with a VELUX flashing kit is guaranteed leak-free for 10 years.
What Is MAGS BAR?
MAGS BAR is a non-structural, maintenance free, aluminum glazing system that is custom built to fit the desired opening.
The bar is designed as a clamping system that sandwiches glazing between two bars. Glazing choices are nearly limitless.
