Flashing A Fieldstone Chimney Along Siding

Along the bend at both ends so that the flashing bends around the chimney at the bottom and overlaps at the ridge.

Flashing a fieldstone chimney along siding.

Once the pan flashing is in place nail it to the roof sheathing and lay the shingles over the flashing. The house will receive a cement style siding panel with no inside corner trim against the brick. I ve looked around a bit and all the details i can find only deal with chimney roof flashing. The project is ocean front and it has become a point of discussion as to how to prevent water from penetrating when we get the sideways rain that we do.

Anyplace where the roof plane meets a vertical wall such as a dormer a chimney or a split level roof flashing is necessary. Pieces of 18 inch wide flashing installed prior to the brick work but on top of the house wrap in a stepped fashion periodically laying on top of the lapped upper portion of the siding to get the water back to the exterior of the wall is more along the lines that i would be thinking of. Sections of l shaped sheet metal are woven into the shingle courses and lapped up the side of the chimney. The other measures should have been taken before the siding was installed.

If this is running along the side of the house and not by the roof then maybe caulk at this point. The first is called step flashing. A second layer of metal is embedded in the chimney mortar joints and folded down to cover the top of the step flashing. Next comes the counterflashing.
