Question Leak Around Chimney

I have a small leak around interface between square brick chimney and tilted shingle roof.

When I lived in Seattle a flashing was built right into the chimney brick. the flashing was about 6 inches above the roof. It kept the immediate area around the chimney dry.

Well this is California and it doesn't rain as much but when it rains it rains just as hard or harder.

q1: Are commercial flashings available that can be attached to the lower part of a brick chimney?

q2: what is the best way to attach to a brick chimney. Banding, screw inserts, concrete nails?

Today its like what can I get buy with. So its like what do you want to do. The first shingles that go there should have what we call step shingles. They where 5"X7" bent up 2" and 3 " on the roof under the shingles. Now we make the step shingles 6"up 6" on the roof 12 " long. After they are worked under the roof shingles. Then you come with the counter flashing 6" wide. Look around there and see if they step this are not. Some take and bend the top edge of this counter flashing 1/4" just a little angle. dope it up on the back with roof cement and use cement nails or PK to tack the top edge to the chimney
Its very hard to tell how when you cant draw it out.Be sure and start from the bottom of the chimney and work up to the top always over lapping as up go up

Find a Roofing materials "wholesaler". Tell them you want counter flashing material. It generally comes in 10ft. lengths. It fastens to the sides of the chimney. It will have a "trough" lip on the top edge which works fine for holding in place a bead of caulking.
The main problem with nailing the roof flashings to the brick, then caulking them, is that they are ALWAYS opening up.
ANY caulking is prone to "opening" up, but using an actual counter flashing as described above, with a quality caulking, can provide years of trouble free service.
Keep in mind that snipping and folding this counter flashing in such a way that it fits good at the corners, while not rocket science, does take a bit of patience and skill-with-the-snips.
