Step 7 - Remove the surrounding shingles
Once you know the outline of the flashing, remove the surrounding shingles with a pry bar. (fig. 19) Composition asphalt shingles
can be installed in various sizes depending on your roof configuration so it is recommended that you remove the entire piece as
you find it in the footprint of the Skylight Tube flashing (fig. 20) Make sure you remove enough shingles to allow the upper 2/3rds
of the flashing to make direct contact with the sheathing and roof underlayment (fig. 21) Save all of the pieces you remove for
re-installation later.

From on the roof, measure 7.25”, (fig. 12) repeat this at 90 and 45 degree angles to achieve a
circular pattern (or use provided template as in Step 2). Then draw in the pattern with chalk. (fig.
13) Using a 1/2” drill bit, drill a pilot hole on the edge of the circle to fit the saw blade for cut-
ting. (fig. 14) Start cutting the circle with a reciprocating saw, as you reach the end of the cut
secure the material by holding onto the exposed screw so it won’t fall into the attic space (fig.
15) Remove the disk of material and discard (fig. 16)
