In a previous post it was mentioned how long warranties are and rigs aren't usually kept that long. A 12 year rubber roof warranty is worthless IMHO. I filed a claim after 5 years service due to the membrane leaking water through the membrane. The company offered to pay $227.00 towards a complete new roof and only if I used their material. No Way.
I had the RV Flex Armor installed for essentially the same money as a new rubber roof and it is superb. I will never own another rubber roof longer than it takes to pick it up and take it to a RV Flex Armor installer and have it sprayed over.
A previous question was the thickness of the sprayed material - RV Flex Armor sprays to 3/16". And for the hearing challenged it is much much easier to hear television in a rain storm.
