pressure wash the roof

I wouldn't use my power washer on my MH roof. I'd use a scrub brush on a long handle and then treat it with a UV treatment after it's dry.

NO pressure washer on the roof...or you will be back here asking about how to repair a leak and a bunch of other damage.

Soft bristle brush, Dawn Dish Soap, or Spic n Span and lots of "elbow grease."

Not sure if this is the best time to wash the roof in Minnesota.

I have used a RV roof specific cleaner and a brush, and try to keep it from running down the sides, but anymore I just use a car wash soap, and a brush with handle. I use plenty of water to flush the roof, then move to the sides and do the same.

Use What roof material maker recommends. Mine says Murphy Oil Soap.
My last one said Spic and Span. I add some bleach because we have Oaks and we get Mildew.

I definitely would not use a power washer.

I've used a power washer on a low setting for years and never damaged my rubber roof. Twice a year cleanings. Use the washer get get off the grime then a rubber roof cleaner and bristle brush. Finally a coat of uv protectant.

I won't have to worry about pressure washing now, as I had a new RV Flex Armor installed last month after some tree damage to the roof. Washer is never going to damage that roof.

Years ago I asked Thor and they said spic and span in a bucket of water, soft brush. They did not recommend any roof treatments. What I do is to mix up a batch of car washing soap with two cups of bleach in a two gallon yard sprayer. Spray down the roof, and sometimes use a soft brush. Let it set for about 10 minutes, then rinse it all off. Go over stubborn spots.

I am in the camp that says no power washer.

Wet & Forget. Best thing since sliced bread. All it takes is a garden sprayer coating on the roof once, maybe twice, a year to keep the roof looking new. I have used it for years and love it.

Like others, I will never use a pressure washer on my RV...anywhere on the RV.

Mine recommends Dawn, warm water and a scrub brush. I just wash mine to get the basic dirt off so it doesn't cause streaks down my sides. Twicw a year only. Nobody sees the roof so I'm not really concerned about it being spotless.

"I use a pressure washer. There I've said it":)

Here is what I do and get good results. First ...think about your equipment before you get up there. I have a 2000 psi with a very wide nozzle. Nozzle is 45 or 60 degree. And I don't get it close to roof because I went to a place that repairs pressure washers and they made me a very short tube. When I hook up to the wand with this short tube, it only comes to my knees when hanging down. Think they charged around $20.00 for cutting to length and putting on a connector. That way there is no danger of blasting thru the roof with to much water pressure when I'm standing upright. I also picked up 10 feet of clear vinyl tubing (cheap) and have the last 10 feet of my hose slid into it, like a protective cover. No more black marks on roof edge or when I drag it around. Just lay out 10 feet of vinyl tubing and cut length wise. Open it up and slide pressure hose inside. Little bit of dish soap to make it slippery if hose binds up. Everything on top that is plastic I give even more space between the nozzle and point of contact, respecting what water pressure can do to plastic and skin. And the hose doesn't roll up worth a darn with vinyl tubing around it.

Other points to watch. Your balance!!!! When you pull the trigger!!!!!

I stand just about in the middle lengthwise (not on edge) when washing and I wear "deck" tennis shoes. It gets slippery depending on what type and if you use soap. Being my ladder is at the rear and right in the middle of RV I usually drag hose up RV ladder, so hose is in middle of RV roof. Hose just follows the top rails of roof ladder. I Don't move my feet unless I have checked where my feet will go first. Another big hazard learned first hand is... with a very short tube...don't pull the trigger if the water could get you. That "spa treatment" in exfoliating my skin doesn't take long. You'll know real quick if you shoot yourself with water. Stung for about an hour, and looked like a bad sun burn couple days, but lesson learned.

I never touch sides with pressure washer.


We've all heard stories about falling of the roof. Anytime your feet are not attached to the earth, there is a possibility that Mr gravity is going to get the best of you. I have actually meet a man that was washing his roof by using a ladder with a long handled brush and fell off the ladder when he was brushing away. He now travels 35 miles one way, to where he can park along side a flat roof and get his roof washed. Of course we all can't have a son with a flat roof on his garage:)

If roof is real dirty, I'm going to use lots of soap. I stand where I can more less stay in one spot. Saves excess moving around. I also rinse really, really good. Because any left over soap will be very slippery.

When washing RV the worst part to me is all the weeds that pop up.
