Roof cleaning?

[Uncamplicated]

How do you determine what type/material your roof is made from?

Thanks! I'll check out Theyford.

I watched a video about 30 sec outdoor cleaner and how a guy uses it to clean the mildew lines on this Solitude roof. Seemed to work pretty good. I might try that also.

I have used 30 second cleaner on decks, gutters etc. I don't think it would be good for an RV roof as it seems to have bleach in it.

I did some research on this a few years ago, I'm going by memory (not always the best idea) but one way to tell is remove the inside trim on your bathroom exhaust fan. The roof membrane will be visible. I believe if it is white on top and tan on the bottom it is TPO. Please double check this or better yet wait for another member to come along with better knowledge. Anyway I think most of our GD roofs are TPO.

I should have read the earlier post on this thread. If GD recommends 30second cleaner it must be ok. Forget what I said, it was just an observation not based on facts.

I use full strength simple green with a brush and pole. Works pretty good.

Used it on our old '94 Jayco TT and your right, worked great for our lake front parked trailer when removing the tree sap and stains!

Not to mention our boats, dock and siding on our lake house as well.....
