TPO and EPDM | How to visually tell the difference
[#2] Posted: 04/22/2012 - 08:53:35 AM |  |  |

The TPO is shiny and feels and looks exactly like a swimming pool liner with heat-welded seams and the EPDM looks and feels exactly like black inner tube material.
ONE TEAM - ONE FIGHT!!!

No one described how to tell whether it's TPO or PVC.
That's a little trickier.

That's (more or less) what I do. I still can't tell lots of times, and have to ask. I hate asking.

So, I am thinking this is TPO because:
whiter than off-white
doesn't look cemented
looks like clean seams
correct?

It's why I brought it up; it's really hard to tell, especially from a pic.
Some of the Durolast jobs I see have joints as clean as TPO.

Single ply membrane it is - for now.
I will start looking at flashing boots for TPO and seams for DO!
Thank you gentlemen.

That's a little trickier. I don't try and figure it out; I tell 'em it's either TPO or PVC and if they're interested in knowing which they should find out who installed it and give 'em a call. I don't really care. If it's right it's right; if it's wrong I write it up and let the roofing contractor figure it out. ONE TEAM - ONE FIGHT!!! Mike
Yeah, but it's better to be right. You know how it is; if I call it the wrong thing, then the goons get all excited about me being wrong.
I hate giving people ammunition.

TPO, in our firm, is referred to as Temporary Plastic Overlay.
In Florida, when it is working at all, it will last longer than PVC. Usually.
PVC is the one that is more expensive.
PVC is more prone to splitting.
PVC sales are largely, from what we can tell, driven by the distributors. Strong distributors, strong sales, and vice versa. A lot of areas they are not selling in. Splotchy coverage, hard to know. PVC'rs don't do Residential normally.
