Cost of a new EPDM roof?
OK, it has been a month since I have had a chance to get any estimates on getting new EPDM roof on my TC. I am in the middle of a restoration on my TC and having a tree limb come through the roof, la...

Sleepy, the one I resealed was my first rv, a 1997 class A Fleetwood Jamboree Rally.

There's a very thorough explanation of the differences between a TPO, which is thermoelastic and EPDM cross linked polymer rubber.
This stuff is used to seal entire rooftops on buildings and is very very durable and remain more flexible.
From the tech part of the site:
The industry has for a long time been trying to come up with a cure mechanism for cross linking EPDM polymers. In 1990, one such polymer was developed and later made available commercially. This has resulted in the development and worldwide sales of Liquid rubber ( Liquid EPDM). The chemistry used in developing the liquid version is similar to the chemistry used to develop a single EPDM rubber ply sheet. The major advantages and differences are in the cure mechanism and a pendant group which is grafted on the polymer chain.
EPDM Liquid Rubber cured films have excellent weather ability. Also, they aren't thermoplastic which means they can be able to withstand high temperatures of up to 300° F and still remain flexible at temperatures as low as -62° F. Cured films are also resistance to polar solvents, acids and alkalis. They can also cope with total water immersion for an indefinite time period.
The Firestone site which manufactures both EPDM and TPO gives them both extremely high marks for durability and resistance to weather.
I'm not championing either, I'm just trying to clarify that this stuff is NOT a paint.
I only suggested it as an easy to apply, very cost efficient method of resealing a roof.
Here's a link to the Firestone site, with both if you'd like:
