   What's the ht of your chimney now?  above the closest ridge/dormer within 10 ft?

   Roof slope?

   Overhanging trees?

   Roof low in relationship to a wall of taller trees on the side of the prevailing winds?  I know you say other buildings, but what is whipping that wind b/4 it gets to them?

   And of course, what kind of chimney-is your smoke staying hot enough to create a decent draft?

   A great place for Information, Comraderie, and a sucker punch.

   Thanks for the interest. Its a 12" triple wall flue straight up 34' with 14'above the eve of a 12;12 roof. (2' higher than the nearest point 10' away) the flue is enclosed in a faux chim once it leaves the eve. This slope of the roof faces SW. I'm on a hill overlooking DT Cincinnati with buildings all around. Some times on gusty days and even with a good blaze going I'll get smoke. The weather vane type cap is more appealing but does have moving parts. I've seen them on the coast on Oregon. The other type is simpler but may not compliment this 1880's Queen Anne.

   Luke, I had this "bonnet" made up by a local commercial roofing co. for about $400. The main goals were to keep rain and critters out of the chimney. It's made of stainless steel.

   that looks nice and may work as the prevailing wind would hit it on the side. Thanks for the interest.

   that is exactly the setup i need for ours because not enough of the flue liner extends above for a regular cap to grab.i've seen similar methods of attaching but with screen on all four sides and same shape as the chimney, with a cap above.

   In Scotland we call these 'grannies'  -   as in grandmother.  It can lead to confusion when you say granny is on the chimney.

   Sometimes the top section swivels with the wind, has a fin on it to keep the spout pointing away from the wind.
