How to flash a chimney for a metal roof.

Bend legs up the chimney sides about 1 inch. A different type of flashing is a chimney pipe boot. Secure a shingle over the corner flashing using a hammer and roofing nail. Instead of having to cut flashing materials yourself you can buy a fitting boot for your chimney pipe.

Place a second piece of 8 inch 20 3 cm flashing against the chimney. Trim panels to fit around the chimney. Hammer 2 roofing nails into the flashing and roof. Cut two opposing 45 degree notches into z closure to allow a 90 degree bend.

These work better on smaller round chimneys and may be ideal for a stove chimney in a metal roof. Place the step flashing over the caulk and onto the chimney.
