And since seams can be welded with hot air, there are no poisonous fumes to deal with. Both 15 and 20 year warranties available.

Cons- Being solitary ply, they are prone to discarded cigarettes, sharp objects went down on the membrane, and broken glass from containers tossed on roof (this occurs a LOT) I typically discourage consumers from mounting these types of systems if the roof has a lot of foot traffic or is easily accessible to unapproved workers. In the past, material shrinkage went to times a serious issue on Thermoplastic and PVC roof coverings, however modifications in make-up and production has actually relieved this problem.
