its been really windy here lately and im gettin nervous about my chimney. its 11 feet above my roof on my porch , duratech stainless chimney , i got the support bracket at about 5 feet up , but there is still 6 feet of pipe unsupported above it and im afraid the wind is gonna take it down sometime , it wobbles a little when it really gusts , i called my fireplace store where i got the stove and they said its normal. what can i do to make it more rigid ? ad another bracket higher up ? or ....?

scared in ny.
 
There is supposed to be a support bracket every 5ft above the roof edge. Definitely add a second brace at the 10 ft level.

This is from DuraVent's installation manual:

"If the chimney extends more than 5 feet above the roofline, an Extended Roof Bracket must be installed at every 5-foot increment
of chimney height above the roofline, leaving no more than 5 feet of chimney extending above the last pipe bracket."
 
I agree you need one more support for that tall of a chimney.
 
The above advice is right on the money, as usual:) those support brackets come in different lengths and are usually telescoping in nature to get the exact length you need. You are right to be concerned and looking into a remedy for this. Having a good wind and your chimney coming apart with a fire going would be disastrous.

Some Installers may try to talk you out of it, but stand your ground and have them do it- it's your family and your job to protect them.

Happy Burning!
