I have a relatively newly built brick chimney (about 4 years old),
and I get water into my attic during sustained rains.
I've also had the roof & flashing just redone, and my roofer believes
the problem is with the chimney or crown. The chimney is large (about 3' x 6' x 3' high).
The brick/mortar & crown all seem to be in excellent shape, and there are caps
over the 2 flues. But the crown is very level; there is no flashing between the
crown & the brick; and the crown does NOT extend beyond the brick.
I'm thinking of putting a new crown on top of the existing one, such that it does slope
down from the top, and extends beyond the brick. Does that sound doable?
Can I put a new crown on top of an existing one (there are no cracks or anything;
and it's sealed with a product called 'Crown Saver')? Will it hold?
What kind of cement should I use to build it, and what kind of mortar should I use
to attach it to the existing one? Also, anyone have experience with brick sealants,
like DEFY Masonry Crack & Joint sealant? The chimney was supposedly sealed with
Chimney Saver when it was built, but now I wondering if some of the water is getting
in through the brick & joints. Any other suggestions would be greatly appreciated.
Thanks very much.
