How long does a PVC roof last?

Owners of commercial and industrial structures in Dallas, Texas need roofing materials that can take the weather changes and last for decades and PVC roofing has proven to be the one many rely on. What does pvc stand for in roofing? PVC is the abbreviation for polyvinyl chloride and is a single-ply roofing membrane popular on commercial or industrial roofs.

PVC roofing is similar to other membrane roofing membranes like EPDM and TPO in the fact that it can be applied to an existing roof. The eco-friendly solution to commercial or industrial roofing is one of the things that make these materials so popular. 

A well-engineered, professionally installed, and well -maintained PVC roofing can provide up to 25 years or longer service in protecting a commercial or industrial structure. Any type of roofing material, EPDM, PVC or TPO can give as little as 5 years longevity or 25 years and more, it all depends on how well it is engineered, installed, and maintained. 

There are many variables that affect the lifespan of any type of roofing material, but roofing experts feel that PVC roofing systems have less variables, giving it a longer life span Because PVC roofing has been used for more than forty years, it has gone through the trials and tribulations of being teste and used. 

Lessons were learned early on with the failures that were caused by the plasticizer not right, or contractors installing it with direct contact to incompatible materials. The past 30 years have all that put behind it now and PVC roofing has been the ideal material for commercial and industrial structures. 

Is pvc roofing good?

Absolutely, because pvc roofing advantages are many and make it the right choice for many commercial and industrial structures. PVC roofing is a two layer roof with polyester added between those two layers for support while keeping it flexible. The benefits include:  

  • Durability: PVC roofing is a remarkably strong membrane with heat-welded seams creating a watertight bond. 
  • Wind Resistant: The heat welded seams make PVC roofing wind resistant up to Category 3 hurricane strength.
  • Fire Resistant:  PVC roofing is hard to ignite, making it a favorite by insurance companies. 
  • Chemical Resistant: PVC roofing is resistant to chemical exposure. 
  • Environmentally Friendly: PVC roofing membrane is highly solar reflective, wasting less energy and helping ease cooling and heating expenses. 
  • High Alkaline Resistant: PVC roofing membrane provides a high endurance to alkaline conditions.
  • Bacteria and Fungi Resistant: PVC roofing is resistant to bacteria and fungi growth. 
  • Install Over Existing: PVC roofing can be installed directly over an existing system, saving money from tear off process and saving landfill space.

How much does a PVC roof cost?

PVC roofing should be installed by an experienced roofing contractor. The average cost range starts around  $750 per square foot and can reach as has as $1,250 per square foot. For a 1,200 square foot flat roof install, the total cost would be $9,000 to $15,000 for PVC roofing that is mechanically attached to the current roof deck. Any repairs or replacement of the current roof deck could increase these prices. 

How is pvc roofing applied?

A PVC roofing can be installed in 3 different processes, all involving a heat weld to ensure the seam strength and make a roof that is resistant to water leaks and wind.  The processes to install PVC roofing are: 


This is attaching the substrate with a special adhesive. This is a easy, quick method but if the roof deck has poor ventilation, the adhesive is known to come loose. It is recommended to have the fully adhered method reinforced by mechanically attaching the membrane to the roof deck along the perimeter.


For  PVC roofing to be mechanically attached, barbed plates and heavy duty screws are used to hold the membrane in place. This method ensures resistance to hurricane-level winds. 


PVC roofing that is ballasted installed is loosely laid across the substrate and is held by manufactured concrete pavers, other heavy weight materials. 

What is the difference between TPO and PVC roofing?

TPO roofing membrane is made of wither ethylene or polyethylene thermoplastic that is bound to ethylene propylene rubber. PVC roofing membrane is made from polymerizing vinyl chloride monomers with plasticizers that increase flexibility while making it stronger.

What is the difference between pvc roofing vs epdm?

EPDM roofing is a synthetic rubber, (ethylene propylene diene monomer) that has proven to be a weather resistance material at a cost-effective option. PVC, roofing offers exceptional seam strength with heat-welded seams.

With all of this information, what is the best material to cover a flat roof in the Dallas Texas area? For many commercial and industrial projects, PVC roofing is the most preferred choice and most recommended by roofing contractors.
