Next comes the counterflashing.
Flashing a fieldstone chimney along siding.
The other measures should have been taken before the siding was installed.
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.
The first is called step flashing.
On each end of the pan flashing cut about 1 1 2 in.
Along the bend at both ends so that the flashing bends around the chimney at the bottom and overlaps at the ridge.
Proper flashing around a chimney includes two layers.
Once the pan flashing is in place nail it to the roof sheathing and lay the shingles over the 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.
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.
If this is running along the side of the house and not by the roof then maybe caulk at this point.
A second layer of metal is embedded in the chimney mortar joints and folded down to cover the top of the step flashing.
