Most new RVs built right now have rubber roofs. Rubber roofs are quite durable and if maintained properly they can last the lifetime of the RV itself.
Again, proper maintenance is the key to how long a rubber roof on an RV will last. The roof on your RV should be cleaned and inspected at least 3 times a year. Cleaning the roof regularly prevents build up of tree sap, bird droppings and other harmful chemicals that can speed up the deterioration of a rubber RV roof.
If a rubber roof is damaged, they can also be easily repaired using products such as Eternabond.
