Before getting started: Understanding how flashing and counter flashing work will help you better to complete the installation steps below. Most chimneys are built on a separate foundation than the dwelling and need to have flashings that can move independently without breaking the water-tight seal with the roofing material. Therefore, flashings used to tie in with the shingles are fastened to the roof only (leaving the upper flashings free standing). Counter flashings are used to guide rain, ice & snow over the flashings and down the roof. These flashings are fastened to the chimney only leaving the bottom portion free standing. Take a moment and read over these instructions for a better understanding of the overall project.

| Step 1. Ensure roofing and pre-existing primary flashing (including roofer's tar), is properly sealed. Note: Side counter flashings may appear to be wider as they are cut on an angle. For best appearance, keep tops aligned. Caulk tops of counter flashings for water run-off. |
Step 2. For best appearance, install your counter flashing with the tops aligned all the way around the chimney. Starting with both sides, use a soap stone or chalk and mark along the tops leaving a slight gap at shingles for drainage. Align the top of the front and back counterflashings with the tops of the side counterflashings and mark. |

Notch out counter flashing ends as shown and bend around to the sides of chimney. For best results, cut top portions flush with |
Place side counter flashings along your mark and cut flush with the front counter flashing. Notch out the rear corner as shown and bend tabs around to the back. Insert 2 to 3 more masonry fasteners. |
