How often do you wash your roof?

you're 'sposed to wash them? seriously...i don't get up there anymore but sometimes the RV guys do. i do have the roof smoke-tested for integrity every year.

Wash mine once per year and keep it in an enclosed garage. Still gets dirty though.

Mine's outside. 24/7.

Mine sits under a shade structure but with the dust here in Vegas its not so white looking, what works best to bring back the bright white look, hosing off does very little.

Depending on the roof type they are supposed to be washed every 6 months or so. It’s very important to keep the roof clean as it’s the only way to verify that the sealant is in good condition. I try to follow that schedule. I also inspect and reseal the roof on the same schedule. It’s far easier to keep up on the roof cleaning and maintenance than dealing with a leaking roof. I just inspected and resealed my sidewall a few weeks ago and I checked and resealed the roof earlier this year. I’m paranoid about water. It’s also why I have a mechanical dehumidifier in my coach.

What do you wash your roof with?

I inspect and wash mine once per year. I use Dawn dish detergent and a bucket of warm water and a hose.

I have a small RV with a silicone roof. I do a full inspect and wash maybe twice a year with a terry cloth pad, tad bit of car wash soap in a spray bottle and just hose water to restore it to a gleaming clean surface. Otherwise a hose (and maybe a rag) is usually enough for regular cleanings, which are done as needed. If I'm getting regular rains, it cleans itself, but if I have multiple Haboobs rolling over me, I clean much more often.

I guess it all depends on your roofing material and the conditions that roof is under.

We washed ours at least twice a year. How would you inspect your caulking/sealants if you don't get on the roof? Especially for a rubber roof it will last longer with washing.

Once per year is what the RV dealer told me. I have a 2001 Nomad with a rubber roof (I think). I use Simple Green.
