Hello,
I am looking for some advice on repairing flashing over my inlaws bay window. Recently, the flashing gave way during a heavy rainstorm. In my section of the country (northern Alabama) builders apply flashing to brick with Lexel caulk which seems to hold well for 10 years or so (in this case). The flashing is not folded into the mortar, and I was thinking that might be a better fix. Is it okay to cut a straight line in the face of the brick with a masonery blade and then caulk the flashing into this groove or is there a way to cut the mortar in a step fashion? Or perhaps I should just reapply new caulk and hope for the best?

rocky.. i'm guessing this is a brick wall ..
the joints should be raked, new metal flashing inserted into the joints.. secured with wedges... then the joint gets remortared...... so the flashings would "step" up the bay window roof hips and then level across and "step" down again
you can also use a PL -masonary culk in lieu of the mortar
here's a chimney we reflashed last summer... there was no cricket , so we added one while we were at it...

Thanks for the advice, Mike. You are right, it is a brick wall. What is the best way to rake the joints? IS the 10 year old mortar that soft or do I need to take a mini grinder to the joint?
Use a grinder with a diamond blade. The reglet will not be much wider than the metal so it won't need much of a wedge. Caulk the reglet after flashing. I prefer Geocel 2300 caulk (I can usually get pretty close to the mortar color with their variety).
