Flashing A Fieldstone Chimney Along Siding

The first is called step flashing.

Flashing a fieldstone chimney along siding.

I ve looked around a bit and all the details i can find only deal with chimney roof flashing. The house will receive a cement style siding panel with no inside corner trim against the brick. Anyplace where the roof plane meets a vertical wall such as a dormer a chimney or a split level roof flashing is necessary. Proper flashing around a chimney includes two layers.

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. Sections of l shaped sheet metal are woven into the shingle courses and lapped up the side of the chimney. Next comes the counterflashing. A second layer of metal is embedded in the chimney mortar joints and folded down to cover the top of the step flashing.

If this is running along the side of the house and not by the roof then maybe caulk at this point. 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. Once the pan flashing is in place nail it to the roof sheathing and lay the shingles over the flashing.
