Installing chimney surrounds
When installing chimney surrounds for your chimney you will need the right tools and instructions.
Measure the height and width of the chimney pipe and the pitch of the roof. You can also purchase chimney surround extensions for high chimney pipes.
Tools and materials needed
- tin snips
- roof tar
- roofing nails
- block of wood
Drill screws into a wooden board a certain distance away from the edge to build a bending jig. Secure the board in a vise that is on a workbench. Bend the flashing using the producer’s instructions.
Cutting surrounds to roof
The surround must match the roof’s pitch. If it doesn’t, cut it and adjust it to the proper size. You will need heavy metal shears to cut through 22 gauge steel surrounds. To fit the height of the chimney pipe, cut panels at the other end.
Cutting cap to pipe
Cut a hole in the center of the cap that comes with the chimney surround. The hole must have the same diameter as the chimney pipe. The cap will slide over the pipe once you attach it to the side panels using the mounting brackets.
Sealing brackets and nails
Using roofing tar, seal the strips of flashing before securing them into place with nails. Any gap in the roof made by mounting bracket screws must be sealed and covered with tar.
Lay the surround
Screw or bolt the mounting brackets into the roof frame around the chimney pipe. Place the surround panels on the outside edges of the mounting brackets.Follow the producer’s instructions if you are not sure about your skills.
Reinstall chimney cap
Slide any existing spark-arrest or draft inducer onto the chimney cap above the surround panels. Be sure to leave space for the cap while you work on the project.
