Getting bad backdraft on windy days

[googlealchemist]

This was installed before I moved in here and I'm trying to fix the issue.

On windy days our house will fill with smoke, really bad to the point of having to put the fire out.

My limited understanding so far is that the chimney does not extend far enough above the roof lines to prevent bad backdrafts like this?

Is it as simple as adding an extension to the existing chimney and/or getting one of those expensive caps that are designed to prevent this or what else should I do?

Thanks

Yes your chimney is definetly too short and in a bad location. At the very least I would try adding another 4' length and a roof brace.

I had the same problem adding a section of pipe did the trick.

But also i see that your chimney is short too as vwmike says
