Coating a newer EPDM roof?

My 2004 Crossroads roof is doing just fine. I crawl around up there a couple times a year and take a close look at all the joints, but so far so good.

On a 2011 I would not worry about it, just do your normal inspections.

The material warranty on EPDM is pretty good, I think at least a decade. I wouldn't coat the roof because over that period of time, a lot can happen... Replace it when it needs to be replaced instead.


The sealants are a lot more likely to fail than the EPDM... Especially if you're not diligent about maintaining them.

Don't depend on a coating fixing any water leaks. This is a newbie perception, that coating the roof fixes leaks. The integrity of the roof against leaking is done with sealants/tapes that prevent water from entering.

In another thread, the OP has discovered a rotten floor section near a wall.. The best thing you can do is perform a pressurized interior leak test. That will turn up even a pinhole leak anywhere in your TT. Do a search for "Pressurized leak test".

Mine is 16 years old and still in good shape.

Ours is 12 years old I'm thinking of coating it this summer it'seems looking like it could use it.

RV roofs are very subjective, do what you think is right. Look closely see if you see any cracks. If you do, then fill them with dicor and keep it with you.
Its better to be proactive then to chase damage.
When the rubber material gets old and black, you
can coat it with one of the coatings made for this.
I do this on the roof and crawl under to check for
problems before they become serious. That's just me.
