I have decided on using PVC for a .5/12 nearly flat residential roof. The home is located on the coast and gets moderate to heavy winds (not hurricane speed though) and salt air. The roof is not walked on. We will be wanting a heat welded, mechanical seamed roof.
Is there one brand of PVC that you would recommend over another or some brands that you would stay away from?
I am deciding between
Versico, Weatherbond, JM, Duralast, IB, etc.
Any recommendations, brands I should use, avoid?
