Secure a shingle over the corner flashing using a hammer and roofing nail.
How to flash a chimney on a metal roof.
Place the step flashing over the caulk and onto the chimney.
Place a second piece of 8 inch 20 3 cm flashing against the chimney.
Slide the rubber boot over the pipe to check the fit.
Remove the rubber boot.
Trace the outline of the base of the rubber boot onto the metal roof with a pencil.
Apply butyl tape to the underside of the closure.
Place a small drop of caulk where the roof and chimney meet at the chimney corner.
If you use nails to hold the overlaps you should use a nail gun instead of a hammer to drive the nails into the flashing.
Panels above the chimney should be removed.
Bend legs up the chimney sides about 1 inch.
Use metal screws or nails to hold the overlaps together then apply caulking material on the seams to seal them off.
Cut two opposing 45 degree notches into z closure to allow a 90 degree bend.
Trim panels to fit around the chimney.
