Rubber Roofs

I think that fear of rubber roofs is somewhat overblown, probably because many have bought an old, poorly maintained, leaky rig as their first RV or have seen or read horror stories about costly repair of water damage. Our 2004 Tioga has a rubber/plastic roof that does not leak and had been minimally maintained. All roofs have vents and air conditioning that units that make large holes in the roof that must be kept sealed throughout the life of the rig. Damage from objects that rip the material must be repaired. Leaks in the clearance lights and front window on the overhead must be inspected for and fixed when needed.
Weep holes in the side window frames must be kept clear for drainage or water may come inside. When buying a used rig, check overall roof, vent, and overhead for inside and out for evidence of leaks including smells and stains etc., inside.
