EPDM roof 14 years old and wore out, now what ?!

my EPDM roof is 14 years old. has LOTS of black showing .. most cracks are eternabonded and sealed with decor lap sealant..

but what about the entire roof being almost black ?


what are my choices ?

any reason I can't Eternabond my ENTIRE roof ? has anyone ever tried it ?


I CANNOT remove the ac, all vents, then clean and scrape, then primer, and then coat a new coat of rubber foot ... not myself ..
  • The stuff really works and it's pretty easy. I power washed then scrubbed the existing with "Crud Cutter" from Home Depot. Cut in the edges with a paint brush then use a paint roller on the roof. Make sure you run the stuff through a bag style paint strainer first since it is very chunky. I put down 4 light coats over two days. I think I used about 1.5 gallons. I touched it up with one coat after three years. It's been 5 years now and will do one coat next year to maintain. Has not peeled, cracked, chipped. I highly recommended it.
  • Is there any reason i cant do part of the roof at a time ? Say 1 section each weekend, over 3 weekends ?

    Really no primer, and dont have to remove anything ? Maybe i can do this afterall

    You don't have to remove anything. I did remove the vent covers just to make it easier. It was four bolts on each cover. I didn't touch the A/C.

    I did 30' of roof. It took two days, but I took my time and left the roof dry overnight. I also used a small roller to apply the Heng's because I wasn't in a hurry and wanted to check the roof as I rolled it.

    Depending on the length of your RV, you could probably do it in a day, especially since you have the Eternabond and Dicor applied.
    Just wash, let it dry and roll on the Heng's (or whatever you use).
    I chose Heng's because no primer is needed.

    Last year I restored the 20 year old EPDM roof on our Southwind.
    It had a lot of black exposed.
    I covered the seams with Eternabond and Dicor self leveling lap sealant.

    After washing the roof, with Tide powder detergent, i applied two light coats of Heng's Rubber Roof Coating.
    It looks good and held up to sun,wind, rain, snow and ice.

    You can E/bond the entire roof but, why? Restoring with Heng's, or the coating of your choice, is much easier and a lot cheaper.

  • I'll probably be coating my roof next year. Probably get me 5 years maybe more? After that it will be a new roof.
