I am re-installing a wood stove and need to replace the roof flashing. The pipe is 6" ID and 8" OD. Do I need to purchase a 6" flashing or an 8"? Also, do you recommend one brand of flashing over another that may have a better universal fit?

Answer:Most of our roof flashings are listed with the pipe's inner diameter. So this SuperPro flashing will indeed work for your 8" outer diameter pipe.

My wood stove has a little downdraft issue. I noticed creosote is coming out from under the collar of a steep pitch roof flashing. Could this be a part of the downdraft problems and would clogged vents under the collar be the problem?

Answer:Unless smoke is somehow being forced downward towards the collar, creosote should not be leaking from beneath the storm collar or flashing. The Class A piping is designed to be completely sealed at each joint and leakage should not occur at any point along the way. If there appears to be no buildup above the flashing or collar, it would be prudent to check the pipe joints near the flashing to make sure they are not leaking.
