HOW TO CLEAN A RV RUBBER ROOF

Alongside the freedom and adventure of RV ownership comes the responsibility of maintaining its components. The roof of your RV is constantly exposed to the elements, including rain, sun, snow, and ice, so staying on top of regular maintenance is important to prevent costly repairs or leaks.

With proper cleaning and regular care, an RV roof can last up to 20 years. Plan to clean the roof about four times per year or more often if you travel frequently. Pay close attention to the caulking and seals, as cracks or gaps can allow water to enter and cause damage over time.

Effective RV roof maintenance starts with knowing your roof type, whether rubber, aluminum, or fiberglass. Rubber roofing is the most common because it is lightweight and cost-effective. If your RV has a rubber roof, check to see whether yours is made of either Ethylene Propylene Diene Monomer (EPDM) or Thermal Polyolefin (TPO). EPDM roofs may need to be resealed every 3-4 years, even with regular upkeep.

Choosing the right cleaner is also important. Rubber roofs made of EPDM have lower resistance to solvents and oils compared to TPO. Many manufacturers recommend avoiding harsh, abrasive cleaners, petroleum distillates, citrus-based cleaners, or mineral oils as they can damage the rubber membrane. A safer option for routine cleaning is Simple Green All-Purpose Cleaner, formulated to remove dirt and grime without leaving behind harmful residues that degrade your RV rubber roofing.

Directions for Cleaning a Rubber RV Roof

Tip: Use caution when working on an RV roof to prevent slips and falls.

Tip: Always follow RV manufacturer’s and warranty’s instructions for proper roof access, maintenance, and cleaning.

1. Dilute. In a large bucket or container, mix 6 ounces of Simple Green All-Purpose Cleaner with 64 ounces (which is 8 cups or ½ gallon) of cold water.
2. Clear loose debris. Using a broom, clear the RV roof of any loose dirt or debris such as leaves.
3. Rinse. Use a garden hose to spray down the roof. Wet the sides of the RV as well to prevent streaking in case the cleaning solution runs down the sides. Wet surfaces help dilute runoff immediately, which prevents visible lines or residue.
4. Wash. Use a mop or a soft car-cleaning brush and bucket to apply Simple Green All-Purpose Cleaner to the RV roof, working in small sections so that the cleaner doesn't dry before being rinsed off (drying makes it much harder to remove).
5. Scrub. Use a mop or soft car-cleaning brush to scrub and agitate any stains, grime, or residue to allow the dirt to lift up.
6. Rinse. Using a garden hose, rinse each section as you go. When finished, thoroughly rinse the entire roof and sides of the RV.
7. Dry. Using a microfiber cloth, immediately dry the roof of the RV to prevent water spots or streaking. Alternatively, you may allow the roof to air dry outdoors in the sun.
