Deck Mount
A deck-mount skylight is designed to be installed directly onto the roof deck, creating a low-profile, seamless look.
Unlike curb-mounted skylights, deck-mounted models sit closer to the roofline, improving energy efficiency and aesthetics.

Roof Pitch
Best for steep-slope roofs with a pitch of 3:12 to 137:12.
Ideal for homes with asphalt shingles, tile, or metal roofs. Great for new construction or full roof replacements where a curb isn’t needed.

Flashing
Step Flashing (EDL) – For asphalt shingles, wood shake, and slate roofs (1/2" max thickness).
High-Profile Flashing (EDW) – For tile roofs over 3/4" thickness.
Metal Roof Flashing (EDM) – Designed for standing seam and corrugated metal roofing.
Copper Step Flashing (EDL COPPER) – Premium option for high-end roofing materials.
