New roof! Should I use TPO or EPDM ??

[JimMartin]

Going to replace my Roof this summer on my 34' Coachmen. Has several patches in it right now, but needs to be done soon. The roof I have now is EPDM. But I've read that the TPO is easier to install and that it help reduce the temperature inside the coach because it's white on white?

The EPDM will run about $150 more then the TPO. Just wondering is anybody has done a roof in TPO?

Your thoughts?

I did. They want $4800 to do my 34' RV! That's crazy!!

Check coating it with EPDM Liquid rubber, check on here for several folks that have done so. It is a DIY product. Cost in hundred not thousands dollars.

TPO is the tougher of the two materials, and does not have the sluffing off of the top layer as EPDM. There are several companies that sell kits for diy application. Dicor is one of them.
In an RV application there should be no need for seams.

I haven't used TPO in an RV application, although like you: ours will need replacing in the near future. TPO is the way I'm leaning as it's more of a resilant material compared to epdm. From past expierennce in commerical building applications I've seen the durabilty, but the installation is much more tedious than epdm.
EPDM is great but can tear more easliy than tpo. Unlike epdm tpo needs its seams welded with a special welding iron and rod. In your case depending on your rv size you might not need to worry about seam welding, but depending on your rv roof profile, you might have to miter some of the corners and then the seam welding would come into play
keep us up todate with your project and good luck

Have you considered using a spray on bed liner? At least one high end RV manufacturer is offering it as an option.
