shingle roof make holes 5” below the bottom of the shingle above the penetration.

5. Using a hole saw, cut the hole (penetration) for the 2 hoses or pipes from step 3.
6. If using flex hose: before connecting the hose, measure, cut, and lay out the hose,
including enough length for 8’ of hose above the roof. Pull the hose through the hole.

8. For composition shingle roof, DO NOT PENETRATE THE COMPOSITION SHINGLE.
Before installing screws, lift the composition shingle at the install point and slide the
mounting bracket in, beneath the top composition shingle. Place the bracket so that
the top surface composition shingle clears the bracket when folded (lifted) up or down
and mark an outline of the mounting bracket where the mounting bracket will be
fastened to the roof rafter or other appropriate mounting substrate. The marked area
should be 1.5” wide and 2.5” high.
