Out of sight, out of mind is not a cliche that should be applied to RV roofs. They should be cleaned several times per year, and inspected for any potential issues.
During cleaning, scrub your RV roof with a medium bristle brush, or any other brush recommended by the manufacturer. You can use a cleaning liquid while doing this, but be sure not to use cleaners made with petroleum solvents, abrasives, or citruses, as those will weaken the strength of the roof materials.
After scrubbing, rinse the whole RV thoroughly, both roof and exterior walls. Any grime dripping off the roof will go down the exterior walls, and if not rinsed, will leave ugly stains.
Inspecting the roof while cleaning is vital, and should be done thoroughly. Check all sealants and seams, skylights, vents, and roof rack for mold and cracks. Fix any rips or tears immediately, before they snowball into other problems.
To passively protect your RV roof from weather damage, keep it away from weather, and avoid the sun! RV storage facilities are ideal for protection, but RV roof covers will separate the roof from the elements. Be sure to use a proper RV roof cover and not any other kind of tarp, which can reduce airflow and result in mold.
