around here the roofer is supposed to inspect the chimney cap when
doing a complete re roof.

the roof was replaced in july, the carbon monoxide poisioning in
december

so it definetely was a problem when the roof was replaced.

and since my ladder doesnt reach to the chimney height and i dont like
heights to begin with its the roofers job and a pretty easy one at
that.........

I have replaced chimney caps on other homes since then.

Inspect cap if its cracked remove broken masonary, clean area so new
cement sticks.

Mix new cement and place neatly and finish so its smooth. Mostly the
hassle is the inconvenient location.......
