Rubber Roof Maintenance for Motorhomes

Roof Inspection

• Inspecting the roof twice yearly minimizes the chance for severe damage, both to the roof and on the inside of the motorhome. A tear in the rubber roof can result in water leaks that cause interior damage. Inspect the roof in spring and again in fall, especially if you park your motorhome during the winter months. Look for visible tears and weak spots. Inspect the area surrounding vents and openings to ensure the roof is sealed in place. Also look for signs of mildew or mold growth.

Repairs

• RV suppliers sell rubber roof repair supplies. The most common is an adhesive repair tape that mends small tears. Sealants made especially for RV rubber roof seals any gaps that form around vents and other roof openings. Follow package instructions when using any repair material to ensure proper use. Your motorhome manufacturer may recommend specific products that work best with your specific roof. More extensive damage, such as a large rip from a tree branch, requires professional repair.

Cleaning

• Rubber roofs develop a chalky residue over time. This residue doesn't damage the roof, but it's unattractive and it may leave streaks on the side of the motorhome as it runs off during wet weather. Avoid abrasive or oil-based cleaners. Acidic cleaners and those containing citrus also damage the roof. A soap formulated for use on rubber roofs works best. Wash the roof down with the soapy water, using a sponge mop, then rinse thoroughly. Rinse the sides of the motorhome after cleaning the roof so chalk or soap residue will not remain.

UV Protection

• Constant sun exposure can cause the rubber roof to weaken prematurely. A twice-yearly application of a UV protector prevents sun damage from ruining the roof. Use a protector formulated for use on rubber roofs and follow package application instructions. Generally, you must spray or roll on two coats. The roof requires two applications a year – once in spring and again in fall. Apply the UV protector after inspecting, repairing and washing the roof.
