It’s time to clean your RV’s roof. Here’s how to do it and what you’ll need

It’s that time of year: RV roof-cleaning time! There are several things you can do to alleviate some of the angst associated with this job. Take a look!

Are you ready?

  • Check your owner’s manual to know if it’s safe to walk on your RV roof.
  • Also, check to see what kind of cleaner is recommended for your type of roof.
  • Climbing a vertical ladder, like the one on the back of most RVs, can be difficult. Always keep three points of your body in direct contact with the ladder.
  • Wear rubber-soled, non-slip shoes or boots. A wet roof can be very slippery!
  • You should be well-rested and sober before tackling this job. (Duh!)

Equipment to clean the RV’s roof

  • You’ll need a medium-bristle brush or sponge mop. This is the one we use. It connects to the garden hose and a toggle switch easily turns the water on/off. It’s really handy!
  • Water source (garden hose).
  • Smaller nylon scrubber for tough spots or stains.
  • Cleaning agent.

Let’s do this!

  • Some of the soap will run down the sides of your RV. To prevent so much soap from sticking to the sides, wet them down with water before you begin cleaning the roof.
  • Use a rope tied to the handle of a bucket to get everything up and onto the roof.
  • Start the cleaning process at the front of your rig and work back towards the ladder. (Always look behind you before stepping backward! There are lots of things to trip over, and it’s a long way down to the ground!) A “spotter” on the roof with you can help you stay safe.
  • Work in 3’ by 3’ sections. Apply soap, scrub with a circular motion, and then rinse.
  • Be careful walking near the roof vents, air conditioners, and other places where holes may have been cut into the roof reinforcement beams. These areas, as well as other places, may not hold your full weight. Tread lightly!
  • Once the roof is done, rinse the sides of your rig again to remove any soap.
  • Let the roof dry. Then apply a roof conditioner, if you choose.

How often do you clean your RV’s roof? Do you apply a roof conditioner? We’d love to know if you have additional tips or tricks to make this job easier. Share in the comments below.

What are best cleaning agents for roof. I use Dawn but what about the black that hard to take off?

1 roof had a peeling roof coat the other roof is brand new in your pics
Impossible to get a roof to go from peeling to new.
Show real pics of before and after
Your after pic would cost $8,000 plus to look like that

I wash my tt after every trip, this includes the roof. I protect it with 303 twice a year and a third time if needed prior to winter. I use a stiff brush as I want to expose any cracks, loose caulk, etc. We travel from March through November and do 3-5 trips each year. I am not concerned with keeping my roof bright white.

We are having trouble finding a Medium Bristle Brush to do the roof on the RV. The link above in your article brings you to Soft Bristle Brush. We’ve checked on Amazon, Walmart, Lowes, and Home Depot with no luck. Can someone tell us where we can find a medium bristle brush to clean the roof?

Check boat dealers and Boat suppliers in your area. Boats and RV’s use the same equipment

Try ace hardware or your local hardware store or an rv outlet.

I use a standard 18” floor broom purchased at Lowe’s. You can feel the bristles to determine how course they are. Or, check a few auto parts stores. Some sell long handled brushes for truckers to wash their rigs.

I agree, plus it looks like the roof is peeling.

I scrub down my fiberglass roof when winterizing and again in the spring. I use a mild soap/water mixture in a bucket and long-handled brush. For those stubborn spots, I also take a small kitchen scrubber sponge and my kneeling pad for detailed work. I drag my hose onto the roof and use a pistol type nozzle to rinse frequently. To avoid the hose from falling back to the ground, I tie a loop of string or light rope from the hose to my lower leg so it’s always convenient and ready to squirt when needed.

I clean my 34′ roof at least once a year – sometimes spring and fall. I use a soft brush, small pressure washer and MeGuiars Wash and Wax in the press. washer jar. I bring the press. washer up on a rope and everything else in a bucket on a rope. (I re-coated the fiberglass roof 3 yrs. ago with Dicor white for fiberglass. (A superior, hard finish and easy to clean product – I highly recommend it!). I also wet down the sides as I go. I only use the brush on tough stains if any – and the press. washer on a milder or not a forceful setting. (Don’t forget the sunglasses – even on a cloudy day!)

I clean campers for other people all the time….
Here is my big secret….skip the bucket of soapy water….soap and little water in a 1 gal pump sprayer makes things lots easier.
Hose down roof spray on soap and scrub away.
On heavy mold I add some outdoor bleach to the mix and let it sit….
When washing the roof you need to keep the soap on the roof and off the sides or you end up with big streaks on the sides

Dave, I hope you see this. THANK YOU SO MUCH for your comment. I cleaned my roof today using your method. So much better. We have a fifth wheel and the key is not looking down.

303 UV Protectant Spray. I buy it by the gallon.

I bought one of those brushes from Camco. Broke 10 minutes into first job. I don’t think I would want the hose hanging off the back of that brush while on the roof.

Same here. Leaks like crazy and too heavy when it’s extended. I still use it, but without hooking it to a hose. I just dip the brush in suds in a bucket. Shoulda just bought a small broom.

I use “Beast Wash” by Duratain to clean every part of my RV. It is the best all around cleaner you will ever find for your home on wheels. It even removes Black Streaks that are caused from Awning Arms with no effort at all. I tried Black streak remover and it did absolutely nothing. But a little Beast wash (full strength on a rag) took the streaks off immediately.
For my RV roof, I use a Gallon pump up sprayer with a Beast Wash/Water mixture and simply spray the roof, let it stand for a minute and then use a soft bristled brush to clean the roof better than anything else I have ever used. Rinse the roof after you have done a section. By section, I mean approximately full width of the roof by about 2 feet towards you starting at the front. Use a hose splitter and have two hoses handy. One for you and one for your partner on the ground to make sure none of the run off dries on your RV sides. I promise you, this will be the fastest and easiest roof cleaning you have ever experienced.

(Continued from above)
We lease an annual spot at an unconventional Campground in NC and I have actually gone over and helped my neighbors wash their RV’s with Beast Wash. They now all use it and love it. I even use it on my car. It is safe for all surfaces. This is not a paid advertisement and I am in no way affiliated with the makers of Beast Wash. But when something impresses me this much, I like to spread the word! Happy camping!

I clean my roof every other time I wash the rig. As I’m getting older (I mean Mature!) I don’t like getting up there as much! I do use a bucket every time I do any maintenance on the roof, tied to a carribeaner hooked to the handle. It works great for bringing rags and tools up there too.
I like to clean my vents and covers while up there as well. Like you say, Be careful up there, it’s a long way down!
