Lance trailer “flat roof” makes roof water ponds -- problems

Something you might want to consider. Look at Inland coatings. Look at "case studies" couple of them are from our area. Look at rc2000. If you want to peruse it further call Corp and get manager for our area. He lives close to Seattle. He offered to show me his RV that he owns. Hopefully he hasn't moved on. I'm very pleased with results on my x rental for many years now. EPDM/rubber roofs on buildings have flat roofs also. If you need other info pm me.
