INSTALLATION - ROOF FLASHING: RETROFIT APPLICATION
Cut the pliable roof fl ashing sleeve on the 190/200 marking and trim to suit tube size..
Cut the roof fl ashing seam and aluminium base with sharp tin snips.
Apply a liberal bead of silicone to one side of the cut seam,
With the seam in a downstream position wrap the cone around pipe and attach the fi rst double clip at the top
of the seam using multigrips.
Attach the remaining clips working down from the top of the cone to the base.
Apply a neutral cure silicon sealant on the underside of the fl ange.
Turning the fl exible fl ange back makes this simple.
Press the roof fl ashing into the contours of the roof confi guration.
Using self drilling washered screws or sealed rivets, fasten the roof fl ashing to the roof by placing fasteners on
either side of the seam fi rst and then fi tting fasteners progressively outward in opposing pairs to avoid gaps.
Apply sealant to the top of the base closure and any other potential leak areas.
In certain applications it may be advantageous to install the fl ashing on the
diamond
or bias.
This particular installation method is especially suitable when having to seal enlarged holes, for penetrations
on steep pitched roofs.
