Mayday... need some advice. I've been experiencing some kind of chimney leak and the roofers can't seem to fix the darn thing. I live in a roughly 19 year old condo in PA. These are two story buildings, one condo per story. I'm on the second floor and above me is the attic. The chimney is a box running up the side of the building and it has two exits... one for my fireplace and one for the downstairs fireplace. Recently we had our roofs replaced and at the same time they painted or replaced the chimney caps. Ever since then I've had some kind of leak when it rains, and the story is the same everytime...
During the initial hour or so of rain, even if it is a very hard rain, there is no sign or sound of a leak. Then I start to hear dripping sounds coming from within the chimney. The dripping sounds continue for an hour or so beyond when it stops raining. Water seems to be dripping onto metal in two general areas... 1) in the chimney at the level of my ceiling, and
2) onto metal in the vicinity of my fireplace. The only signs of water are in two places... a) on top of the firebox or whatever it is called (I can just stick my fingers up in there and feel that the top is wet), and b) under the fireplace (I can peer into a gap at the bottom of the fireplace and see some water seeping in). Initially alot of water came in (gallons), but after several repair attempts my guess is that we're down to a few cups or so. It is hard to tell because I think now virtually all of the water is falling somewhere behind or to the side of the firebox and only a tiny bit seeps in underneath. FWIW, some small amount of water has appeared in the same places around the downstairs unit's fireplace also.Does anyone know anything about fireplace/chimney construction and can hazard a guess as to what might be going on? My uneducated guess is that water is dripping onto a metal firestop near the vicinity of my ceiling, then from there dripping onto metal around the firebox. The thing that kinda confuses me is that there is a good delay before it starts dripping and then it continues to drip long after it has stopped raining. Can water pool in the cap? Once water is in the chimney, could it then get down to both fireplaces or would the fact that both are affected suggest there are similar problems with both caps? Any advice appreciated. Before I ping the associate again I wouldn't mind having some sense of what is going on. Thanks in advance.
