Leaks - chimney flashing or roof?
The house is an antique cape, with full dormer in front . The roof is 22 yrs old and very swayed in front (when they dormered yrs ago they cut out some beams and the roof sags). Its a 200 yr old house - no attic, and center chimney which is hidden behind walls of second floor bedrooms,but is full exposed in living room below (wood ceilings, old post and beam. You can walk around the whole fireplace). I have had drips running down outside of fireplace (i can see this in living room). I assumed chimney flashing needed repair (4 yrs ago)and that water was coming in thru flashing and just dripping straight down outside of chimney. A roofer reflashed (someone from same company recommended chimney rebuild because said water can actaully come in from outside of chimney then work its way back to outside of the brick and drip down outside?. It seemed ok for a while then was dripping again. A second roofer last year said it wasnt done properly and he did some repair. Shame on me for not knowing exactly what he did. Its been leaking a lot now, all around brick. I just had chimney rebuilt this week from roofline up by a mason. It is flashed 6 inches under roofing shingles (this guy said previous flashing was not far enough under shingles, and that the two flues should stick up a bit over chimney. Mine previously were flat across. I do not have a metal cap on top, which he recommends). Job completed Tuesday. Wednesday we had ton of rain. Yesterday I see it leaking again down the brick in living room. Not as much as before, but leaking. I have no attic so cant look to see where its coming in unless I rip some sheet room down in one room (which is wet anyway and needs to be replaced). Called the mason - he is coming back and says water could be coming down flues and working its way to outside of brick (it is not lined all the way down). So thoughts? Could the water come down the middle and work its way to outside of brick and is dripping down outside of chimney/fireplace, or is it likely to be a roof leak that is working its way over to the center chimney and coming down the brick? If it was was a roof leaking in some other spot, wouldnt my bedroom ceilings be wet? (I have a wood ceiling in one room and sheetrock in another?). Do I have to replace the roof in order to find out? The mason is going to come back tomorrow and flood around the chimney with a hose to see if it starts running into the living room. He thinks though its coming thru center (opening at top) of chimney. Please - any recommendations? Anyone who has been on that roof says it looks fine.
