ROOF CAP INSTALLATION &
MAINTENANCE INSTRUCTIONS
INSTALLATION
Plan installation carefully. Before installing roof cap,
make sure that birdscreen is in place. Refer to Figure
3 under “MAINTENANCE” section.
Roof cap will accept up to 3¼” x 10” rectangular or 8”
round duct. Ductwork may enter roof cap as shown in
Figures 1A & 1B. Tape all joints with duct tape to prevent
air and water leaks.
1. Cut hole in roof approximately ½” larger than duct-
work.
2. Insert ductwork through opening and run it back to
fan or range hood. Leave a maximum of ¾” of duct
projecting above roof surface on the high side.
3. Trim ductwork parallel to roof pitch.
4. Carefully lift shingles and slide back flange of roof
cap under shingles. Nail flange to roof under shingles
at top two corners and two sides. Nail directly to roof
in four places at bottom. (Figure 2)
5. Use roof cement to seal shingles to top and sides
of roof cap. Seal all nail heads with roof cement as
well.
