RV and Motorhome Roof Maintenance 101

motorhome roof maintenance and repair

Your complete guide to getting the most out of your motorhome roof

Owning a recreational vehicle (RV) or class B motorhome is one of the best ways to ensure you’re never too far from excitement and travel. Purchasing a campervan is your gateway for easy weekend excursions and well-planned month-long journeys.

If you’re thinking about buying an RV or are already an owner of one, you may be thinking about maintenance. Many experienced road trip warriors will tell you that maintenance is important, but it doesn’t have to be difficult. Several components of maintenance are electrical, tire care, winterizing your vehicle and, last but not least, making sure your roof is in good condition.

One of the best things about traveling by RV versus tent camping is your roof. Motorhomes withstand most of Mother Nature’s elements and will keep you dry and comfortable all through the night. Making sure your roof is in tip-top shape can make all the difference depending on where you decide to travel.

Browse the information below for expert tips on how to maintain your campervan roof.

Types of Motorhome Roofs

The four most common types of material used for RV roofing are rubber, fiberglass, vinyl and aluminum. Your roof type will determine how you maintain it.

  • Rubber: Rubber roofing will generally last as long as you maintain it. There are two types of rubber roofs: EPDM (ethylene, propylene, diene monomer) and TPO (thermal, poly olefin). Depending on which type you have, maintenance may be a little different (see below).
  • Fiberglass: A fiberglass roof is the typically the easiest type of surface to maintain. Fiberglass roofs are heavy though, which makes them infrequently used in the production of motorhomes.
  • Vinyl: A vinyl roof requires similar maintenance to that of a rubber roof. However, always be sure to check the owner’s manual for maintenance tips specific to your type of roof.
  • Aluminum: Aluminum roofs require fairly low maintenance. However, like fiberglass, it’s unlikely your RV/motorhome has an aluminum roof. Unless, of course, you have an Airstream trailer.

Important note: Always refer to the user manual for your specific make and model of campervan when making decisions about roof maintenance. If you’re unsure of how to best go about maintaining anything relating to your RV, find a local mechanic and schedule an appointment.

Tips for Maintaining a Rubber RV Roof

  • Thoroughly inspect and clean your RV roof several times a year. This is a good way to avoid a costly emergency repair.
  • Never use any harsh chemicals, conditioners or solvents when cleaning your rubber roof. Experts recommend using warm water, mild soap and a medium bristle brush. If you find that you have a surface that needs deeper cleaning, look into purchasing RV-specific cleaning supplies for a rubber roof.
  • Inspect for sealant repair. Caulking your motorhome roof annually is necessary, despite the condition it may appear to be in. Making sure your RV is properly caulked will prevent liquid from seeping into your vehicle. Don’t forget to seal around your vents, fans and raised portions.
  • Touching up your roof can be easily done by applying RV liquid roof sealant. Apply a coating to help fight ozone and ultraviolet ray damage.
  • Think about investing in an RV cover. Using a cover can help eliminate debris and dust from damaging your roof. Be sure to remove your cover frequently enough to make sure mildew doesn’t have a chance to grow.
  • Do you have an RV ladder or rack? Be sure to check the sealants around those areas. Over time, ladders and racks can become loose depending on how much they’re used. Pay close attention and caulk as needed.
  • Don’t forget your air conditioner. Make sure that the filter is clean and free of debris.
