Question:

i have a 2000 aerolite cub travel trailer. I cant tell if it is a tpo or edpm based on the discoloration of the roof. Do you know what type this roof is and what products do you have to repair it? thanks

I don't know what type of roof is on your 2000 Dutchman Aerolite Cub TT however I can help you determine what roof you have.

TPO is going to be on the thicker side (1.1mm - 2mm) than the EDPM membrane, and also has rubbery feel to it.

EDPM on the other hand is going to have a smooth finish to it compared to the TPO, and it is also going to be quite a bit thinner at around .40mm - .90mm.

As far as repair kits go that does depend on what you're needing done. For instance, we have the Alpha Systems Patch Kit for SuperFlex RV Roof Membranes # AL37CV which will work with TPO roof membranes and measures 3' long x 2' wide.

If you let me know what you're needing I'd be happy to help.
