FLASHING
The following are generic installation instructions for installing the flashing around a chimney. Installation of
all types of factory-built chimney systems is to be in accordance with the chimney manufacturer’s
installation instructions. Remove the nails from the shingles above and to the sides of the chimney.
Place the flashing over the chimney pipe and slide underneath
the sides and upper edge of the shingles. Ensure that the
chimney pipe is properly centered within the flashing, giving a
3/4” (19.1mm) margin all around. Fasten to the roof on the top
and sides. DO NOT NAIL through the lower portion of the
flashing. Make weather-tight by sealing with caulking. Where
possible, cover the sides and top edges of the flashing with
roofing material. Apply waterproof caulking, provided with the
flashing, around the chimney, 1” (25.4mm) above the top of
the flashing and push the storm collar down into the caulking.
Insert a rain cap onto the top of the last chimney section.
