Hi all, I have a 7200 sq foot flat roof in Canada, maritime climate. Tried GACO silicone on another roof, liked the product, bank didn’t because oddly enough GACO couldn’t or wouldnt show it had a long history in cold weather climates. My area is also very small, very conservative, and resistant to change, so liquid systems aren’t really known here it seems.
Substrate is mostly weathered SBS and a section of new SBS that leaked.
Anybody have any suggestions for a quality paint-on or roll on product, maybe fleece reinforced, that has a good lifespan and has been around and used in northern climates? One that doesn’t need excessive substrate prep other than cleaning and vacuuming.
I’m looking at a couple other liquid cold applied systems, one is Soprema Alsan 230 Winter Field and Flash. Other systems require putting down a glass coated foam level and then a cement board (not happening).
Thanks a ton everyone, kind of stuck right now with winter coming.
