Whenever it rains, the ceiling becomes wet at the corner of the chimney.
I ASSUME it's just a small leak, but obviously I don't want it to become any worse. I have a flat roof, so getting up there and doing some work is pretty easy for me. Any suggestions on what I need to do? My Googlefu has come up with this plan of attack:
- Repair and cracks I find in the morter with masonry sealant.
- Spray the chimney with water repellent.
- Caulk where flashing meets the chimney with flashing sealant.
