Framing collects condensation faster/longer than the rest of the roof.
As far as cleaning, Jomax and a mop and bucket.
Edit: SAFETY NOTE- work from front to back, or wherever you can go without getting your shoes wet before disembarking. Walking on wet roofing is very dangerous because your fall is going to be all the way down.
I use this stuff: Camco Pro-Tec RV Rubber Roof Care System – Two Step Treatment Rids Dirt and Grime and Reduces Roof Chalking | Extends the Life of RV & Trailer Rubber Roofs – 2 Gallons (41453) https://www.amazon.com/dp/B00T9IR9M6/ref=cm_sw_r_cp_api_fabt1_JqCRFbBV2MBY6
Works pretty well
I just want to say that’s an excellent parking job
Do not pressure wash. So many do it. Agree on the treatment suggested. I usually use soap and a soft scrub brush.
er0h:
after natural wear and tear, how much would it cost to replace the entire roof on a 30ft grand design?
Any roof cleaning product are good. But we use part vinigar, part water, part bleech and let me tell you my roof is white as can be.
I tried murphy’s oil soap for the first time this year, and it was amazing how white it got my roof.
