Pvc Roofing Systems
What is PVC Roofing?
Made from polyvinyl chloride (or plastic), PVC is a tremendous single-ply roofing solution. In addition, it’s made from a lower percentage of oil and petroleum than thermoplastic polyolefin (TPO) or ethylene propylene diene terpolymer (EPDM). As a result, it carries both Energy Star and Cool Roof ratings as an excellent roof membrane.
The two types of PVC roofing systems are mechanically fastened and adhered to.
- A PVC membrane can be welded using heat (hot air, hot wedge, extrusion welder) or chemicals (solvent or adhesive). This method forms lap seams, end laps, detail work, etc. The main advantage of this system is its speed of installation. Also, a well-executed welded seam should have a higher pull-apart strength than the surrounding membrane.
- Adhered systems use an adhesive to bond the membrane to the substrate or insulation. Typically, either a cold-applied or hot-applied adhesive is used. One advantage of this system is that it can be applied to a wide range of temperatures. Also, certain adhesives can bond to damp substrates, which can be an advantage when working in cold weather or when there is a delay between membrane installation and substrate preparation.
Additionally, PVC is a solid and durable material. It can withstand high winds and is often used on commercial buildings that experience severe weather conditions. They can last up to 20-30 years old and are among the most straightforward roofs to repair. Therefore, PVC roofing may be the right choice for a durable and energy-efficient roofing system.
Although a system’s primary purpose is to protect a structure, your roofing system plays an integral part in safeguarding it. UV rays, ponding water, and strong winds conspire to prematurely damage a roof, resulting in leaking, installation failure, costly repairs, and perhaps early tear-off and re-roofing. Titan Commercial & Residential Roofing offers a variety of PVC roofing system designs tailored for any application regardless of slope or site conditions.
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), 200 pounds per square inch.
Because PVC is so strong and stable that it can be installed by heat welding the seams instead of other membranes requiring adhesive or a taped seam, this installation method allows a PVC roof to expand and contract with a building. In addition, thanks to innovations in the marketplace, PVC can also be heat welded to a rubber-coated flashing, ensuring a robust and sealed perimeter that performs over the years, and looks beautiful.
What are the benefits of PVC roofing?
This walkable roof material will last long through PVC roofing membranes’ unique heat welding installation process. The heat welding process creates a permanent bond between each 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.
There are many benefits to choosing a PVC roofing system for your commercial building. In addition to being energy-efficient and durable, PVC roofs are also:
- Lightweight: PVC roofs weigh about one-sixth as much as asphalt roofs, making them easier to install and transport.
- Fire-resistant: PVC is a naturally fire-resistant material, so it will not ignite or contribute to the spread of fire.
- Seamless: PVC roofs are seamless, so there are no gaps or open seams that can leak.
- Low Maintenance: PVC roofs are easy to clean and require very little maintenance.
- Environmentally Friendly: PVC roofs can be recycled, and they do not release harmful chemicals into the environment.

Pvc vs tpo and epdm
Although PVC has a long track record in the roofing industry, TPO, manufacturers, and materials differ in quality. As a result, it’s critical to use a trustworthy provider.
The TPO roofing membrane is less expensive than PVC, and it’s Energy Star certified. It also has greater flexibility, making it less vulnerable to tears, punctures, and impact damage and accommodating building movement and settling without jeopardizing performance.
Another alternative for EPDM is low-slope installations, which are less expensive than other types of slopes. EPDM has the second-lowest slope of all the alternatives, making it an attractive option. Meanwhile, EPDM’s sheet width is 50 feet wide, making installation quicker and labor-intensive.
Choosing the Right PVC Roofing
Chlorine from ordinary salt, and ethylene, from natural gas are the two components of PVC. By combining these two elements with additional chemicals, PVC may be made rigid, flexible, or semi-flexible. This is why PVC is known as a very flexible plastic material.
Rigid PVC is solid and brittle. It is used in construction as piping and siding.
Semi-rigid PVC is somewhere between rigid and flexible. It can be shaped but will not return to its original form once bent. This type of plastic is used in food packaging, wire coatings, and medical tubing.
Flexible PVC is rubbery and bendable. It is used to make raincoats, shower curtains, and hoses.
PVC Roofing Membranes are made from semi-rigid PVC because it offers the ideal combination of flexibility and strength for a roofing membrane. The manufacturing process begins with two linen or polyester carrier sheets coated with PVC. These are then sandwiched around a reinforcing scrim, which gives the membrane added strength and stability.
PVC Roofing systems are available in a variety of colors. The most popular color is white because it helps reflect the sun’s rays, lowering cooling costs by 30%. Other colors, such as tan, gray, and blue, are also available to help complement the building’s architecture or blend in with the surrounding environment.
Is pvc easy to install?
According to Roofing Calculator, PVC is more accessible to repair than other membranes since it can be easily re-welded in sections. A PVC roof can also last up to 30 years. PVC’s longevity makes it a better investment for most roofing projects despite the higher up-front cost. 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 benefits. However, 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.
How Do You Maintain a PVC Roof?
The environmental effect of roofing materials is determined by how long they last. Since they are less likely to contribute to landfill waste, the roofing material that lasts for decades is better for the environment. When properly installed and well-maintained, PVC membrane may endure for decades. Furthermore, welded seams are more robust than the material itself. Vegetated roofs made of PVC are ideal since they do not allow root penetration.
When cared for regularly, low-slope roofing systems endure longer. Regular maintenance on your PVC roof will help it function more efficiently and radiate more light, resulting in more significant energy savings and comfort. In addition, by keeping your roof clean, you can prevent dirt and debris buildup that can cause algae and other organic growth. A dirty roof can also attract small animals and pests. The frequency with which your roof should be cleaned is determined by various factors, such as environmental pollutants, rainfall quantity, and roof slope and drainage.
Why PVC Roofing?
- Longest Industry Warranties. PVC membranes are specifically engineered for strength and endurance, making them the most robust roof system available, lasting 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 are heat welded, so virtually no glue is used for waterproofing.
