Vinke , you've done some huge commercial jobs with this type of system haven't you ,?......if I recall


I don't know jack ....

I started roofing at 16,,,,,,
I don't think I know what the product was that you applied.
I would fully bond a new tpo roof to any any rv I purchased.
give me 30 year of worry free roof

The channels on the side of a RV should never have caulk applied.
This will create a capillary affect issue because you can not get a good seal...
Take off the rubber gasket, put the channels, clean and seal under.
Gutter channel on RV roofs fill with stuff keep them clean



got luckly with a online bidding gig, I do at night, Commercial new construction roofing. (I dont sleep)

largest so far is 719000 sq ft.... part of a air port

AG, did you have to clean or prime old roof coating before applying the new goo?

The roof obviously needs cleaned before applying a new coating. No priming, they’re all rubber or silicone coatings that I’ve seen.

Yeah, I could have worded that better. I meant is there a special cleaner or just soap, water, rinse.

All the ones I’ve used were just soap water and rinse. When really bad I’ve pressure washed beforehand.
