Pvc Roofing Systems
What is PVC Roofing?
Made from polyvinyl chloride (or in layman’s terms, plastic), PVC is a great single-ply roofing solution. It’s made from a lower percentage of oil and petroleum than thermoplastic polyolefin (TPO) or ethylene propylene diene terpolymer (EPDM). As a cool roof membrane, it carries both Energy Star and Cool Roof ratings.
Are PVC Membranes Strong?
PVC is surprisingly strong. The Remodel Gurus lists the breaking strength of roofs made from this material as at least 350 pounds per square inch — far above the minimum breaking strength required by the American Society of Testing and Materials (ASTM), which is 200 pounds per square inch.
Because PVC is so strong and stable, it can be installed by heat welding the seams, as opposed to other membranes that require adhesive or utilize a taped seam. This installation method allows a PVC roof to expand and contract with a building. Thanks to innovations in the marketplace, PVC can also be heat welded to a rubber coated flashing ensuring a strong, sealed perimeter that performs over years, and looks beautiful.
What are the benefits of PVC roofing?
Through the unique heat welding installation process of PVC roofing membranes, this walkable roof material is ensured to last a long time. The heat welding process creates a permanent bond between each individual PVC roofing sheet, forming a solid layer spanning your entire walkable roof. The results of this process are a waterproof and fireproof roof that will last for decades after installation
By understanding what PVC flat roof materials are and what their benefits are, potential buyers are able to make a more informed decision about their flat roofing systems.
Pvc vs tpo and epdm
Although PVC has a stronger track record in the roofing market than TPO, manufacturers and products can vary in quality. For this reason, it’s important to work with a reputable PVC supplier. TPO membrane is a less expensive option than PVC, and is also an Energy Star certified cool roof. But because PVC is more flexible, it’s less likely to break with old age, and accommodates building movement and settling without compromising performance.
Meanwhile, EPDM offers one of the cheapest membrane options low-slope installations. Another advantage EPDM has over its competitors is that it comes in sheets of up to 50 feet wide, making installation faster and less labor-intensive.
Is pvc easy to install?
According to Roofing Calculator, PVC is easier to repair than other membranes since it can be easily re-welded in sections. A PVC roof can also last up to 30 years. Despite the higher up-front cost, PVC’s longevity makes it a better investment for most roofing projects. While a properly installed EPDM roof can withstand rain, snow, UV rays, abrasions, ozone and temperature fluctuations, the seams are not as sturdy as PVC and the membrane can start to shrink and pull apart with the buildup of heat.
Ultimately, PVC, TPO and EPDM all offer their own benefits. Contractors should consider the factors driving a project and a client’s needs — budget, climate or longevity — to determine whether PVC or another roofing membrane is best.
Why PVC Roofing?
- Longest Industry Warranties. PVC membranes are specifically engineered for strength and endurance, making it the strongest roof system available, with warrantees up to 30 years.
- Wide Variety Of Thickness And Colors. With multiple choices of color and thickness, building owners and homeowners have a wide selection of products to meet their budget. The thinner the membrane, the cheaper it will be.
- High UV Reflection. Most PVC roofs are white, with exceptional solar reflectivity, reflecting up to 85 % of UV rays, lowering energy costs.
- Repair Friendly. Even if there is a seam void, it’s easy to take care of it. Even all the flashing and edge metal is heat welded, so there is virtually no glue used for waterproofing.
