We got a new bitumen roof put on last year on our low-pitch addition
roof. We keep getting leaks that eminate from the outside corners where
the chimney (prefab) meets the roof. It looks as though the leak starts
at the outside corner, then some water runs down the middle of the roof
(on the inside, where we can see it saturating certain spots in the
ceiling drywall) - due to gravity, of course.
Anyone know what we need to fix here?
Our roofing company came once and put a lot of silicone caulk on the
corner of the siding, but this did not help. Should we get the chimney
resided, or perhaps something is going on at the top of the chimney?
Note: The house is 15 yrs old, and did not receive proper maintenance
before we bought it 2 years ago.
Thanks in advance,
