Caulks work on roofs too. Does not have to be tar base. I think osi quad depends on solvent evaporation to cure, not water base which I assume can freeze before curing. More important will be working carefully on a roof while the body is freezing.
I have always used polyurethane caulk. The black stuff. I have tried every thing else out there. I’ve had problems with silicone, and any type of latex. Silicone tends to constrict and separate after a few years. Latex(even the fortified stuff) is just not suitable for roofs.
