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 4" high. Be sure inside
measurement of curb is the same as roof opening
measurement.
b) Secure curb to roof per local building codes.
Build curb as shown in drawing. This is the tested/
approved method.
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. Flash curb to
comply with Florida building code.
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 with the"THIS EDGE
DOWN" label at the bottom of the opening. Screw in
place through pre-drilled holes in side with #10 x 2"
Phillips pan head screws provided. Fasteners must be
perpendicular to the curb. Every installation hole must
have a fastener.
11 Interior Finishing: Run drywall (or other nishing
material) up the inside face of the curb.
