RETROFIT APPLICATION
1. Mark the ceiling location for your skylight. Try to install between the
rafters to minimize your work (reference section 3). Before cutting, carefuly
check for electrical wiring above the ceiling. A carefully cut inspection hole
should be used. Cut and remove ceiling and insulation.
2. Make a 3/8’ or 1/2” thick plywood backer board to fit on top of the
rafters under the roof sheet metal. This backer board is used to give the
skylight mounting screws an attachment under the thin sheet metal
roof. The hole in the backer board is the same size as the skylight
roof opening. The backerboard outside dimensions are the same or
larger than the overall dimensions of the skylight. flanges.

ROOF OPENING – Maximum roof
opening must be 1.5” under the
skylight size, either direction.

opening of 14.5”x14.5”

3. Locate the roof openings directly above the hole in the ceiling (use a
square). Draw lines perpendicular with the room ceiling up to the
underside of the roof. Use a sharp object like an awl or ice pick to
push four dents or holes in the roof. This defines the corners of the
skylight opening on to the roof. Use 2 x 4’s or 2 x 2’s to frame the
tunnel up to the roof. Make sure all ceiling and tunnel paneling
edges are supported.
4. On top of the roof, locate the awl or icepick dents and mark the
dotted cut lines.
The cut lines on many roofs can be deeply scribed with a utility
knife and peeled open like a rooftop tin can. If the roof metal is too thick
to peel, use tin snips. Fold the one inch wide edges over flat on top of the
roof and nail onto the backer board and rafter.

The slit allows backer board to be slipped under roofing
material on one side and turned a full circle to get it
under the sheet metal.

5. ALL CAULKING IS TO BE APPLIED TO SKYLIGHT BEFORE MOUNTING. Do not remove protective plastic
cover from the glaze until the skylight is completely installed. Center the skylight above roofing (holding the
skylight away from the roof surface). When you are satisfied with the location, rest the skylight on the roof. Be
sure bottom pane is resting on the roof around the entire perimeter. Install the fasteners, first from the center
of each side and work to each corner. Tighten the fasteners only to the point when you can visually see
uniform compresssion of the caulk. Do not over-tighten fasteners, as it will distort the material making sealing
more difficult. Apply additional caulk to cover screws and to fill any voids around the perimeter, smooth excess
by hand. Finish interior tunnel and then remove the protective plastic from the interior glaze WARNING:
BOTTOM PANE MUST BE SUPPORTED!
SUGGESTED INTERIOR FINISH
Clean plastic with soap and water
ONLY.
6. Insulate tunnel with fiber glass batts stapled or taped in
place. Cut tunnel wall panels from matching ceiling or paneling
and nail in place
Recommend minimum insulation “R” factor
of R-11
