• (Note special kits are available for extraordinary situations and oversizedchimneys.)

Install ice and water shield around chimney. Cut 1” into horizontal joints onthe front and back of chimney at the same height of the roof line (no higherthan 14 ½”) Draw a line on the sides connecting front and back and cut 1”into horizontal joints on both sides of the chimney. Cinder block chimneyscan only be cut in at horizontal mortar joints! Shingle around the chimney.

Position Apron Flashing (AF) in front of chimney. Mark where AF meetschimney line and measure 3” on both chimney lines and draw a line. Cut offexcess on either side of flashing. Cut a diagonal from the top of the hemdown to where it meets the bend in the AF.

Bend metal tabs slightly more than 90 ⁰ for a tight fit against the chimney.

Fasten bottom hem of AF to roof with roofing nails.

Fill in gap with roofing caulk before installing the First Step Flashing (FSF).

Place FSF along the chimney and flush with the bottom of the AF. Draw a linewhere the FSF meets the chimney and 3” further down the top hem. Cut offthe excess top hem and cut a diagonal down to where the FSF meets thechimney line.

Bend the metal tab slightly 90⁰ for a tight fit over the AF and secure thebottom hem of the FSF with roofing nails. Repeat with the other side ofchimney.

Shingle over the FSF.

Install pieces of Step Flashing (SF) overlapping no less than 2” working fromthe front of the chimney to the back. Shingle over each piece of SF.

On the last piece of SF, mark where the top hem meets the back of chimney.Cut diagonally to create a tab and bend slightly more than 90⁰ to hold tightly against the chimney.

Repeat the process on the other side.

Place Cricket Flashing (CF) on the back of the chimney and create tabs andfasten in the same manner as previous steps. Shingle over the back of thechimney.

Prior to adding the counter flashings, the chimney will look like this.

The Front Counter Flashing (FCF) is laid across the front of the chimney.Make a mark where the cut into the brick meets the flashing and trace downto the roof on the panel with the pencil.

Allow for an additional ¾” gap at the top of the panel and 2” on either side.The settling of the chimney and other factors will not allow for a perfectstraight line when you trace. Therefore the 2” should be measured from thewidest point on the line drawn of the panel. Cut out the panel and cut adiagonal at the top on either side so that the FCF will bend without crinkling.

With a hand brake, bend the panels.

Fit the FCF into the grooves. Trim the bottom of the side tabs to follow thecontour of the roof.

The Side Counter Flashing (SCF) is installed similar to the FCF except it ispositioned 1/8 past the front of the chimney and there is only one 2” fold tabto attach to the back of the chimney.

Prior to caulking, here is what the intersection of the SCF and FCF should looklike. The 1/8” edge will provide a pathway for the caulk.

Here is the view from the side.

The Back Counter Flashing (BCF) will be need a ¾” bend the top and extendpast the sides of the chimney 1/8” to provide a pathway for the caulk.

BCF is secured with zip screws into the corners of the flashing, not into thechimney.

Secure all corners of the counter flashings with zip screws being careful not toscrew into the chimney.

Bend a piece of scrap and slide under the shingles under the chimney to catchloose granules during the next steps.

Seal the reglet cut, all corners at the base of the chimney including the seamalong the AF and FSF. We recommend using a high quality sealant such asQuad or Solar Seal to bond properly with the roof granules and hold up to theelements.

Finish with granules from the touch up kit for clean appearance.

Here is what the finished product looks like.
