RV dealers recommend that the vehicle be professionally inspected and repaired. Use the following tips to recoat an RV roof yourself.

Tape off any voids, cracks or openings along or on top of the roof with a commercial roofing tape, available at RV supply stores. Take note that a tight solid bond exists between the tape and the roof itself.
