Roof Maintenance June 04, 2017, 02:42:41 pm I'm curious what others do to maintain the roof. I'm not thinking about the sealant, but the fiberglass. Do folks wax it? Seal it? Paint it?What product line can I use to clean and protect (seal) the roof surface, that WILL NOT cause problems and help eliminate the white streaking that seems to occur with age and UV exposure.
