SKYLIGHT INSTALLATION

INSTRUCTIONS / SLOPED

ROOF:

CONGRATULATIONS… on having purchased the only skylight that does not rely on sealants.

For easy installation, please read the following instructions thoroughly before starting. Note - accuracy is important!

2” x 6” CURB (by installer)

HEADERS (by installer)

CRIPPLE (by installer)

CEILING MATERIAL (existing)

SHAKES/SHINGLES/ASPHALT TILES

ROOF SHEATHING or STRAPPING (existing)

.

JOISTS or BOTTOM of TRUSS (existing)

RAFTER or TRUSS (existing) ALLOW 5 HOURS TO RETURN ROOF

TO SEALED CONDITION

1. PREPARATION:

Planning: Determine the location of the skylight & type of light shaft desired. Check that there are no electrical wires,

water pipes, heating ducts or other obstructions. If there are, relocate them, or change the planned location of the

skylight or type of light shaft.

Tools required: Measuring tape, carpenters square, plumb line, hand saw, electric skill saw, hammer, utility knife,

scraper, tin snips, pry bar, drywall saw.

Materials: 2x6 curbing, 2x4 framing, 1x2 finishing, drywall or other finishing material, nails, paint or stain.

IF THE SPACE ABOVE THE CEILING IS NOT ACCESSIBLE CUT AN 18” INSPECTION HOLE IN CEILING

(APPROX. IN CENTRE OF THE PROPOSED LIGHT SHAFT).

WHAT TO LOOK FOR:

(a) Whether truss or separate rafter & joist construction & their exact location

(b) Width of spacing of above

(c) Depth of light shaft to ascertain if sufficient light will be produced and to estimate materials required.

2. LOCATE “ROUGH OPENING” CORNERS:

on underside of roof, by driving 4-3” nails to protrude through roof finish. It

will now be necessary to work on top of the roof. However, if preferred, it is

possible to cut from the underside with a reciprocating type saw.

Construct the curb to fit standard rough opening size

3. MARKING THE ROOF:

Place the curb over the protruding nails. Mark the roof on the OUTSIDE of the curb 3/4”

beyond the curb. EXCEPT THE BOTTOM which is cut EXACTLY ON THE OUTER

CURB EDGE.

5. THE ROOF SHOULD NOW LOOK LIKE THIS:

6. CUT BACK RAFTERS / JOISTS:

by 1 ½” to allow room for headers top &

bottom. Note the shape of the light shaft

may vary from that shown – but good

structural practices must be maintained.

4. CUT AWAY ROOF INSIDE CURB MARKINGS:

Remove the shingles back to outside of curb (see fig. 4)

7. FLASHING INSTALLATION:

7. FLASHING INSTALLA 7. FLASHING INSTALLATION

Continue with prepared roof hole. Install your one piece Top Pan Flashing under the

shingles or shakes at top of opening. Some of the

roofing nails will have to be removed carefully for

this step to take place.

Build a 2”x6” curb with correct inside rough opening.

Place curb over cleaned area under the top flashing and

toe nail it to the roof.

Install step flashing under the shingles on both sides of

the curb running from top to bottom. NOTE: Based on the

type of roofing, step flashing pieces may have to be cut

short. You also may have pieces that you do not need.

The bottom flashing which is over lapped by the last step flashing

is your next step. After these main flashings are installed, nail all

of them closer to the top of wood curb. The last piece of step

flashing is then bent over the bottom flashing in such a way that

water cannot back-up. NOTE: A small amount of sealant under

the bent (lowest) step flashing is recommended.

The counter flashing (cut to size) is required to finish the

job and give a smooth surface on top. Start with the

bottom one, then install the sides to overlap bottom and

finally fit top counter flashing to overlap both side pieces.

(See correct counter flashing in step 7)

On the flashed curb the counter flashing will come half way over

the top of the curb – leaving half the curb a wood surface. IMPORTANT: After peeling protective strip from butyl

tape (attached to the inner skylight frame by Dayliter),

bring down the skylight on the curb, so the butyl tape

rests on the “wood” surface of the curb to eliminate heat

transfer.

8. LIGHT SHAFT:

MARK SHAFT OPENING at ceiling level with carpenter’s square

CUT CEILING OPEN with appropriate saw - remove debris

9. IMPORTANT:

PROTECTIVE PLASTIC ON THE ACRYLIC SKYLIGHT MUST

BE REMOVED BEFORE EXPOSURE TO ULTRAVIOLET RAYS.
