I recently had my chimney repaired with new blocks at the top and resurfaced. The mason also poured a concrete cap that extends over the edges of the chimney to reduce water from hitting the chimney. The tiles previously extended about 2 inches about the masonry top of chimney but now are almost flush with the new cap. Is this going to affect my draft??
Thanks in advance
 
Steamer,
I doubt that 2" would be noticeable in your draft. The nice thing about having the tiles extend above the top cap, is it would prevent splash from rain or snow accumulation from falling inside. That height is sometimes used to attach the rain cap on, but not always necessary.
 
Anyone else have any thoughts on this ??

If I'm picturing correctly what you're describing, it doesn't sound like there was any change whatever (no matter how slight) to the height of the gas path (flue) from whatever it is you've got down below with a fire in it up to daylight at the exit from the top of the chimney. If that's the case, then there should be no effect on your draft whatsoever. Sounds like he may have made it just a bit trickier to install a chimney cap, if that's important to you. But it can be done in any case. If I'm misinterpreting what you've described, I apologize. Rick

Thanks for the reply and info
Appreciate it
 
I would not want my crown built up to the height of my flue tile. Flue tile is usually set proud of the crown for the reasons double-d suggested. That said, I can't see how it would affect your draft either way. It's a rain, snow and cap issue, not a draft issue.
 
Do you have a chimney cap and is there a wood stove involved?
