Installation Instructions (cont.)
7
Cut shingle around the back of the chimney. This cut can be snug
with little, or no gap.
8
Finish installing shingle course across the back of the chimney and
nail into place.
9
Center the cricket ashing along the back of the chimney allowing the
ends to extend 3 to 4 inches past. Notch out both ends even with their
respective corner and bend tabs around to the sides. Nail in place.
10
Complete the installation of shingles. Check your work thoroughly
now and ensure there are no gaps or openings where ice & water
can seep in.
Part II, Counterashings. Counterashings divert water over and away from the roof ashings and are only fastened to the masonry.
11
For best appearance, install counterashing with tops aligned all
the way around chimney. Starting with both sides, mark along
the tops leaving a slight gap between the shingles and bottom of coun-
terashing for positive drainage. Align the top of the front and back
counterashings with the tops of the side counterashings and mark.
12
Notch out the counterashing ends as shown and bend around to
the sides of the chimney. For best results, cut away the top corners
ush with chimney corners then bend tabs around to sides. This will help
prevent the metal from warping. Install masonry fasteners through coun-
terashing and into chimney. Ensure metal is tight against brick.

Reglet Style
Reglet style
counterashings are
installed similar to
retro style with the
difference being the
tops are cut into the
masonry. This is a
common practice
used by Pros every-
where.
13
Mark rear counterashing even with chimney corners and place
along your mark. Install masonry fasteners. Check the tops of all
4 counterashings to ensure the presence of a “V” notch. As seen in the
detail, caulk all 4 counterashings along the V and at the corners. Ensure
there are no gaps, bubbles or air pockets for water to seep into.
Reglet Style Using a standard masonry saw blade, start at the front
of the chimney and cut slot along mark at a depth of 1 1/4”. Insert coun-
terashing as shown here remembering spring ange will compress. Trim
sides and bend back. Install masonry anchors (usually 2 to 3). Finish
piece by sealing with bead of caulk.
