How to Maintain an RV Rubber Roof

RV roofs are highly susceptible to the elements. Regular cleaning will go a long way to retard chalking and the settling of other air-born contaminates. The edges of the rubber roof will require re-sealing periodically. Inspect the roof for any signs of loose caulking or cracks in the seams. Tape the seams with self-bonding roof tape. Use only a self-leveling sealant approved for a rubber membrane to reapply loose caulking. Seal all intersections where the rubber roof meets the edges and around all vents and skylights. Inspect your RV roof often to prevent a costly roof replacement.

• 1

  Sweep all debris from the roof. Repeat weekly to prevent the build up of residue on the roof.

• 2

  Clean the roof of the RV with dish-washing detergent and water. Do not allow the water to run down the sides of the RV. Allow the roof to dry.

• 3

  Clean the roof with rubber roof cleaner to remove chalking. Repeat a minimum of three times a year to prevent excessive chalking and mildew accumulation.

• 4

  Remove all old, loose or crumbling sealant with the medium-bristle brush, but do not force off any sealant. If old sealant is removed, apply a new bead of roof sealant along the edges of the roof membrane all the way around the roof using the caulking gun. Apply the sealant around every roof vent and the plumbing vent pipe hole, around air conditioner openings and under the trim strips. Apply the sealant around every screw head. Allow the sealant to dry the recommended time by the manufacturer.

  Repair all torn rubber areas with the rubber repair and sealing tape.

• 6

  Apply the rubber roof treatment to the entire roof. Buff the roof with a clean cloth.
