Subject: chronic leaking chimney

3 years ago I had the wood in the interior of my chimney completely replaced due to saturation from water. At the time, a roofer replaced the cricket, which he said was too small for the size of the chimney. He also replaced some decking, reshingled the area, and coated the outside of the chimney to prevent possible seepage. This month I again had water damage on the left side of the fireplace wall (directly below part of the new cricket). This time the inside of the chimney was dry. Is this something a brick mason should investigate or should I again try a roofer?

"I had the wood in the interior of my chimney completely replaced" This doesn't make sense to me? Wouldn't it burn?

What kind of shape is the chimney counter flashing in? I have cut a lot of new flashing into brick before. This is something a lot of roofers have no experience and knowledge on how to do properly. I usually cut in the new flashing for $200 in addition to whatever else I do to a roof. If it is all that you call on me to do for you it would cost about $300. You can view a chimney that I had cut new flashing into HERE.

I have questions concerning the competency and the extent of knowledge that your roofer has. I can flash anything and keep it from leaking even if the cricket was too small. If he made the cricket larger (not a bad idea but not necessary) he would reduce the clearance he has for his roof flashing to fit under the counter flashing that was preexisting on the chimney. Such a thing would most likely require new counter flashing. If he didn't cut in new counter flashing he would have to lower the height at which he could run his flashing up against the chimney. If his flashing has a height of only an inch at its minimum, cutting in new counter flashing now is meaningless. His flashing will have to be redone. The roofer's flashing should bend up the chimney a minimum height of 3" but hopefully 4". When looking at his flashing job to see how high his flashing runs take into consideration that he might have had to cut down the back edges of it to get pass the mason's step. It might appear to be taller on the front edge of his flashing.

"Is this something a brick mason should investigate or should I again try a roofer?" An experienced roofer should be the one to figure this out for you. Its hard for you to figure out just how knowledgeable your roofer is but ask him how he installs counter flashing in brick. He shouldn't be needing to use caulk. Hopefully he can show you a picture of how he's done it before. I don't have time to get into this procedure right now.

Thanks for the forum participation,
