I am looking for opinions (good and bad, pros and cons), about Duro-Last PVC verses TPO (Firestone, Carlisle, etc). Lately I have come across several Duro-last roofs and want to know more contractor's opinions.
TPO, was garbage in the 80's and 90's, remained garbage in the 00's, and after it's 4th or 5th "new generation", I'm willing to bet remains garbage today.
We are seeing TPO failing after 7-8 years here,Some cases even sooner. I agree with you Mike its GARBAGE
I dislike Durolast because it is a poor substitute for Fibertite, and when they point to roofs from the early 80's that "are still in service" they are more than likely membranes that were made by my favorite manufacturer and private labeled to DL.
But I will say with full confidence. Durolast is superior to TPO in virtually every way.

I have been installing Duro-Last for 17-18 years. I have not had any problems with them. For me the prefabricated flashings save me on the for extra employees.
MikeH has shown me Duro-Last failures. He does not like it at all. Has not come between us. We do small jobs mostly. 2 - 5 square. We are doing a Wendy's right now. We did this Wendy's 15 years ago. They did some remodeling and the contractor screwed up the roof real bad because he thought you treat pvc like ashpalt. So we had to replace it. Last winter every snow fall we where there cleaning off the snow to keep it from leaking.
It serves my purpose and my customers purpose.
