Note: For Re-Roof applications, strip and clean around existing chimneys make any required repairs to the substrate and chimney.

1. Install ice and water protector around the chimney, starting at thebottom and proceeding up the sides, finishing at the top. The top should have a minimum of 24” up the roof and 4” up the chimney; the sides and bottom having 8” on the roof and 4” up the chimney.

2. Install the shingle to fit around the chimney; the sealing line should bewithin 3” of the chimney.

3. Install the End Wall Flashing, trim and notch the flashing to extend past the chimney on the roof, and bend the sides up the chimney. Fasten to the roof.  Apply a quality butyl sealant at each corner up theroof a minimum of 8".

4. Start the Step Flashing over the End Wall Flashing and apply a quality butyl sealant on each edge of the step flashing. Continue with each StepFlashing up the sides, finishing at the top by trimming and bendingaround the top.

5. Install the Back Pan Flashing at the top of the chimney and extend beyond the sides of the chimney by at least 3”.

6. Install the Counter Flashing on the sides over the Step Flashing. Trim the Counter Flashing to butt to the Back Pan Flashing and over the End Wall Flashing. Fasten into the chimney at 12” centres down the sides and fasten at the front of the End Wall Flashing using waterfproof fasteners.
