It appears this last storm broke one of two wires supporting the chimney. The broken one is on the right and covered in ice. The remaining one is goes from the stainless pipe to the left and attaches to the garage. Are these wires necessary or are these pipes pretty stable? I haven't measured it, but it's probably 8 or so feet. EDIT: This connects to our pellet stove.

It should be braced at the 5 ft level with 3 guy wires triangulated or a pipe roof brace. Strong wind can have a surprising amount of leverage.

Yes brace it. Especially since santa will be here soon
 
If the wires aren't cutting it, perhaps beefing it up some with the roof braces.
 
Thanks for the replies. I'd feel much better to get a bracket on it. The roof is pretty much flat, so sliding snow and ice is not much of an issue. Just wind. I'm assuming this is a 6" pipe connected to the pellet stove. A piece of the pipe on the interior that I can see reads Metalbestos 6s.18. Does that sound about right?
 
Your install manual, per code requires bracing. Yes, the pipes are stable, but as pointed out, wind can generate serious force. Suppose in a high gusting wind the pipe separated at the joint below the roof line while you have a good fire going.....! You need the Roof Brace kit or URBK.

Not being able to see the roof contour due to the snow load from what I can see I'd run one leg off the facia trim and properly triangulate the other leg. I wouldn't consider your wire to be remotely sufficient for that much exposed pipe. I would suggest that when you brace above the roof that you also look to see if and interior re-support kit might not be helpful as well.
