Roofing membranes made of PVC are capable of passing this standard as all of them have a breaking strength which is a minimum of 350 pounds for every inch
Hot Air Welded Seams and Its Durability
Because of the hot air welded seams feature, it allows roofing membranes made of PVC to become exceptionally durable, strong,with a high impermeability against moisture. Seams welded with hot air can form a bond that is watertight and permanent which can actually be stronger compared to the membrane. Since this is the case, PVC roofs can be more advantageous in comparison to other roofing systems that usually depend on caulks, tapes, and adhesives in order to make the seams sealed. Because of this, they can be inherently and significantly less durable compared to the PVC.

Despite this, it will not make a negative impact on the membrane made of PVC.
