Determine the ashing to be used with the roof
opening chart. Slide ashing over pipe until
base is at against roof. Replace as many
shingles as needed to cover exposed area
and ashing base. Secure in position by nail-
ing through shingles (see Figure 16). DO NOT
NAIL THROUGH FLASHING CONE.
When installing the ashing on a metal roof,
it is required that putty tape be used between
the ashing and the roof. The ashing must be
secured to the roof using #8 x 3/4" screws and
then sealed with roof coating to prevent leak-
age through the screw holes. A roof coating
must also be applied around the perimeter of
the ashing to provide a proper seal.
Place storm collar over pipe and slide down
until it is snug against the open edge of the
ashing (see Figure 17). Apply waterproof
caulk around the perimeter of the collar to
provide a proper seal.
