Installation Guide

5 Build curb (or use Sun-Tek’s pre-built, pre-ashed

insulated “Labor Saver” Curb)

a) Construct curb with 2x4’s, 2x6’s, etc. (depending

on height desired or building code requirements).

Curb should be minimum 3½" high. Be sure inside

measurement of curb is the same as roof opening

measurement.

b) Secure curb to roof per local building codes.

6 Shingle roof up to bottom of curb.

7 Flash curb (or use Sun-Tek’s pre-formed, pre-cut Step

Flash Kit with one-piece head and sill. Step ash for 2x4

curb only). Use galvanized sheet metal, aluminum, or

copper. Metal should extend a minimum of 4" over

shingles (on bottom side), then up sides of curb.

Flashing should be ush with curb top.

8 Shingle up sides and across the top.

9 Apply a ½" wide bead of caulking on top of the curb

around the entire perimeter. Sealant applied too close

to the opening may “ooze” into the opening. Can also

use 1" wide by 1/8" thick butyl tape, if compatible.

10 Set skylight over opening. Nail in place through pre-

drilled holes in side with #8 x 1¾" galvanized ring-

shank nails.
