| A friend asked me to examine the flashing on her chimney and give her an
assessment. The chimney needs tuck pointed and a few bricks are cracked;
mortar and silicon caulk will solve that problem. The flashing, however, has
pulled away from the brick. It appears that whoever did the last roof job,
didn't put the flashing in the mortar joint but simply affixed the flashing
to the face if the brick and sealed the edge at the top. It was dark when I
say the job so I couldn't determine exactly how the flashing was affixed.
What's used to hold flashing to brick when installed this way?

| Usually plastic roof cement (sometimes called mastic or goop, Foogle:
http://snipurl.com/ijs7).
You could repair with cement, fiberglass webbing, more cement, and,
after a wait, if you want, some roof paint.

The yahoos who did my roof used polyurethane caulk when they put the
flashing in, just as you described. . I had to go on the roof every
year to recaulk the seam and it never was water proof. After one
horrific rain storm and having rain come pouring down the fireplace
wall in the living room, I hired someone to repair it the right way
and embed the flashing in the morter. Not a problem since.

Unfortunately, that seems to be the normal install these days. It amazes me
how people will accept shoddy workmanship on their long-term home, yet
demand perfect fit and finish on their automobiles which is constantly
subjected to wear, tear, and road rash. "Cheap labor" has all but run off
the master craftsmen of yesteryear.
