I have a mildew problem on the roof because I have to park under trees. How do you control the problem without using bleach? I understand that bleach is not good for the roof.

Thanks guys

 

A mild bleach solution will not hurt EPDM (rubber) roof. Make it mild and apply it with a wrung out sponge mop so it doesn't run down the sides - - clean the roof first, then apply the bleach lightly.

 

Ditto what FiverBob says, thats the best way!!

 

Thanks guys, I guess about a cup of bleach to a gallon of water.

 

We have found in our medical practice and from various informed sources, that in the case of bleach, "more" is not better. We use a 10% solution for cleaning and it works great. But we are guys, and we seem to think that is a little is good, more must be better, or faster, or something ? I use the same on my RV which lives under an oak hammock, and a spritz with that, followed by a quick rinse (with, as advised, an eye to the sides of the RV for streaking), then a brush with regular car wash soap solution works fine. Power washers can also be good - they will do the trick with no bleach - just another option.

 

Plus I always wash the trailer after I clean the roof.

 

That is quite strong. Do not expect it to turn white before your eyes - - if it does, it is too strong. That is why I suggested washing the roof first, then a light coating of the bleach solution and don't rinse it. It will continue bleaching as it sits in the sun.

 

My trailer always sits under a covered awning when not in use, it gets dirty but never just really bad. Not meaning to change the subject but I noticed here recently that the rubber roof membrane on mine had a few small wrinkles in it, is there cause for alarm or is this normal wear on the rubber roofs. It use to be pretty tight and I don't walk around on top of it when cleaning. This is the first trailer I've owned with the rubber roof.

No sweat on a few wrinkles in the roof fabric. After time almost all EDPM roofs will get a few small "wrinkles." These are no problem. Watch out for the big "bubbles." These indicate a serious problem. By the way, make certain that you keep the roof clean with good calking around the edges and fixtures.
