Mildew on roof

[egh33]

What is a good product to remove Mildew from the roof of Motor Home
When the weather does a rapid change the ceiling of the carport where the Motor Home is stored, there is condensation drips from the ceiling of the carport.
I have sides on the carport almost with in 3 feet from the ground. But I got a lot of mildew on the roof of Motor Home. I have tried a lot of car wash product cleaners. So far nothing works
Got any ideas??
Thanks

Two ideas: spray the roof with Wet and Forget AND cover the roof with a Sunshield tarp like I do.

After you remove the mold of course.

I have a very large fan in there. But I guess I don't turn it on at the correct time.
Around here the weather changes pretty fast. It was 72 yesterday 95 today Suppose to be in the low 80's tomorrow.

Mildew shouldn't stick to fiberglass. A stiff bristle brush and good cleaner should work. Just be aware that anything you put on the roof that is aggressive will strip the wax off the sides. Including the afore mention rubber roof cleaner.

You got that right, That's what I'm afraid of.

Ajacks, scrub brush, and elbow grease.

Followed by a good waxing.

What is your roofing material? If it's a rubber roof, I recommend this for cleaning:

Rubber Roof Cleaner

Then, when it's done, follow it up with this:

Rubber Roof Treatment

I had quite a few mildew stains and bird dropping stains. When I got done with both products, my roof looked like it came right off the factory floor.

It would be nice to know what kind of motor home with what kind of roof so good accurate info can be given to use on specific roofs.
