I see several things guys…
It looks like two clay flue liners are present. The chimney cap does not extend past the brick edge of the chimney so water rolls down the "edge" and keeps the brick wet during a wet period. Any Chimney covers... doesn't look like.
The crack around the liner / cap looks as if the temperature changes maybe helping this condition. Perhaps some movement with temp changes.. What is the Chimney cap material and quality ? Looks like a lousy mix of material? The cracks in the cap material will let water into the cracks and let freezing aggravate the condition even more.
The flue pipe / smoke pipe pictures scare me.. This huge gap needs to be sealed Period. Looks like Cat 1, natural gas burning, natural draft appliances to me connected to the chimney.
