Flashing A Fieldstone Chimney Along Siding

Next comes the counterflashing.

Flashing a fieldstone chimney along siding.

A second layer of metal is embedded in the chimney mortar joints and folded down to cover the top of the step 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. Along the bend at both ends so that the flashing bends around the chimney at the bottom and overlaps at the ridge. On each end of the pan flashing cut about 1 1 2 in.

The other measures should have been taken before the siding was installed. Proper flashing around a chimney includes two layers. Yes you can caulk but in reality you should also be using chimney flashing which gets attached to and sealed to the chimney and then gets bent over the j channel. Anyplace where the roof plane meets a vertical wall such as a dormer a chimney or a split level roof flashing is necessary.

If this is running along the side of the house and not by the roof then maybe caulk at this point. 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. Sections of l shaped sheet metal are woven into the shingle courses and lapped up the side of the chimney.
