PVC Roofing

PVC Membrane’s Installation on a Flat Roof

PVC roofs are often chosen by homeowners who want to have a system that is ecologically friendly installed over the flat or low slope roof. Every time the removal of the old roof is needed, the total cost of the installation may be higher depending on the scope.


Roofs made of PVC are engineered specifically to become strong and to ensure the membrane’s extended life of service. It is required by the ASTM or American Society of Testing and Materials to have a membrane for roofing that has breaking strength at a minimum of 200 pounds for every inch.

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.

Service Life that is Long

Because of their exceptional strength and durability, PVC roofs often provide a long life of service. Whenever it gets installed properly, it can be possible for the PVC roof to last for more than two decades. It may not even require a lot of maintenance during its life of service. Because of this, whenever people invest money on a roofing membrane made of PVC, they may eventually save thousands of dollars on expensive repairs and maintenance in the following years.

Chemical Resistance

Commercial buildings that have a PVC roof like facilities for manufacturing will not have any problems in roofing when it gets exposed to chemicals. That is because PVC can be very resistance against damage from chemicals. Aside from this, the animal fat from the restaurants’ grease vents may eventually damage roofs based on asphalt including other roofing membranes with a single-ply. Despite this, it will not make a negative impact on the membrane made of PVC.

Wind Resistance

Because of the heat used in welded seams including its inherent strength, PVC roofs provide great resistance to wind uplift. A lot of the in-service membranes were able to survive hurricanes under Category 3. The recommended choice for especially high-rise and low buildings that are located in places that often experience strong winds is the PVC roof because of its strong wind resistance.
