I then determined I have TPO roof. The local rv store sold me "alpha" self leveling lap sealant saying its the best on the market and better than Dicor. The dicor scared me away and I bought into the more expensive Aplha sealant, because the Dicor tube said NOT compatible with all TPO roofs. Also, the example test spots at the rv store made it look like to me the manufacture used Alpha lap sealant the first time around and not Dicor. It seems after curing Alpha is more flexible ad soft than Dicor, and whats on my roof now seems flexible and soft.
Any one know a specific type of cleaning agent I need to use on my TPO Roof? And also a maybe a agent I need to wash with a couple times a year?
