Understanding PVC Roofing Systems

PVC roofing systems, or polyvinyl chloride roofing systems, have been gaining popularity as a durable and reliable choice for commercial roofing system applications in commercial and industrial buildings. These PVC roof systems consist of single-ply PVC membranes that offer high durability and resistance to fire, chemicals, and hurricane-level winds, making PVC roofs an excellent option for a roof system.

Invented in the 1960s by Sika Sarnafil, PVC roofing has come a long way since its initial use for shoe heels and shower curtains.

Components of PVC Roofing Systems

PVC roofing systems are comprised of three primary components: the top sheet, reinforcement scrim, and base sheet. The top sheet is a performance layer that is exposed to the environment. It can be affected by various things, such as wind-borne dirt, airborne contaminants, UV radiation, and foot traffic. Sandwiched between the top sheet and the base sheet is the reinforcement scrim, a weft-inserted, anti-wicking fabric.

The base sheet serves as the foundation, providing strength and stability to the PVC roofing system.

Common Applications

PVC membranes are widely used in low-slope roofs for commercial and industrial buildings. They are one of the two most popular single-ply roofing system options for commercial white roofing membranes alongside TPO membranes. As a roofing membrane, PVC roofing membranes have been praised for their recyclability and environmental product declarations.

Their performance has been assessed based on product design, product manufacturing, membrane durability, corporate governance, and innovation according to the NSF/ANSI 347 standard.

PVC Roofing Membrane, Installation, and Cost

Comparing the available options is wise when considering a roofing system for your commercial or industrial building. Outside of TPO, PVC is a single-ply roofing system that property owners and commercial roofers install due to their material properties, ease of installation, and fair cost.

In this section, we’ll delve into these factors to help you make an informed decision.

Material Properties of PVC Membrane

The PVC membrane consists of two PVC plies that sandwich a polyester reinforcement sheet. The PVC roofing material consists of polyvinyl chloride, a form of plastic, and other additives that strengthen and give it a high tear strength rating. PVC is known for its durability, long service life, and resistance to chemicals, fire, wind, and water.

PVC Installation Method

The installation methods for PVC roofing are similar to that of other single-ply, flat roof membranes. PVC roofing systems and membranes can be installed using fully adhered, mechanically fastened, or ballasted methods. The seams of PVC membranes are joined together through heat welding, resulting in strong and durable connections.

The choice of installation method will depend on factors such as the specific needs of the project, as well as the expertise and preferences of the contractor.

Cost Considerations

The cost is a significant consideration when comparing PVC and other roofing systems. Generally, TPO roofing systems can have a lower initial cost than PVC ones. The price of PVC roofing typically ranges from $4.00 to $12.00 per square foot when installed, depending on the quality and thickness of the membrane.

However, it’s important to consider other factors, such as maintenance and repair costs, as well as the expected lifespan of the roofing system, when making a decision.

Understanding TPO Roofing Systems

TPO roofing systems are a single-ply roofing membrane made with synthetic material and reinforcing scrim that provides a dependable and cost-effective roofing solution for commercial buildings and flat-roof properties.

Its UV resistance, heat-reflective properties, and flexibility make it popular among roofers, commercial contractors, and property owners.

TPO roofing is a relatively new addition to the roofing materials market, with about 33 years in existence. Still, it has already gained a reputation for its performance, especially on flat roofs.

Composition and Features

TPO is a single-ply three-layered membrane composed of a TPO polymer base, a polyester-reinforced scrim, and a TPO compounded top ply. Thermoplastic, in layman’s terms, means it becomes plastic when heated and hardens upon cooling.

TPO roofing offers superior stability and resistance to shrinking compared to EPDM, another popular thermoplastic membrane roofing material. An EPDM membrane can alligator, while TPO is less likely to shrink over time, resulting in a long-lasting, reliable system.

Furthermore, TPO roofing provides significant energy cost savings due to its highly reflective properties, which deflect the sun’s UV rays away from the building, keeping the interior cooler and reducing energy consumption.

Note: Geographic regions higher in altitude with high UV levels adversely affect the TPO and are often the number one problem TPO systems face in these regions.

Types of TPO Roofing Membranes and Their Thickness

TPO roofing membrane is typically sold in 45 mil, 60 mil, and 90 mil thicknesses, which is about the thickness of a heavy-duty trash bag. A thicker roof membrane should be considered for roofs that experience higher traffic (i.e., walkways or technicians routinely servicing rooftop units).

Two primary types of thermoplastic membrane roofing exist: Polyvinyl chloride (PVC) and thermoplastic polyolefin (TPO). TPO membranes have three layers, making them a highly durable and efficient choice for commercial buildings.

The TPO single-ply roofing membrane has gained popularity due to its energy advantages and durability. With its ability to resist heat and most UV rays, TPO roofing is an eco-friendly option that can yield significant energy savings for building owners.

TPO Roofing Installation Process

Following the specified installation process for TPO roofing is crucial to its performance and longevity. A high-level overview of installing TPO involves preparing the roof surface and substrate, choosing the proper insulation and thickness, attaching the membrane, and using a hot-air gun to weld the seams.

The heat-welded seams create a watertight seal that prevents leaks and protects your building’s interior. Hiring an experienced contractor to install TPO roofing is highly recommended due to the specialized tools and expertise required for a successful installation.

The layers of a complete, fully adhered TPO roofing system are as follows:

1. TPO membrane
2. Bonding adhesive (if fully adhered)
3. Cover board (recommended on roofs with regular foot traffic)
4. Insulation
5. Vapor barrier (optional, but roofs over concrete decking should always have a vapor barrier)
6. Underlayment (typically installed when an improved fire-resistive rating is required)
7. Roof decking

Preparing the Roof Surface

Before installing a TPO roof, the existing substrate must be appropriately prepared to ensure a successful installation. This involves cleaning, repairing, and priming the substrate to create an even surface for optimal adhesion. A flat surface is essential during installation to ensure proper adhesion of the TPO membrane and prevent water damage.

Priming the substrate is a crucial step in the installation process. It involves applying a primer to the substrate, ensuring optimal adhesion. Once the surface is prepared, and the insulation foam is installed, the TPO membrane can be attached securely to the roof deck, providing a durable and energy-efficient roofing system.

Insulation and Mechanical vs Adhered Attachment Methods

Insulation sheet foam is the component that dictates energy efficiency and must be installed to guarantee a satisfactory level of heating and cooling efficiency within the property. Several insulation options are available for TPO roofing, such as foam board or batt insulation. The type of insulation selected depends on the existing roof type, necessary insulation levels, as well as the specific needs of your building.

The TPO membrane can be mechanically attached using fasteners or attached using a fully adhered adhesive system. In mechanically fastened systems, the membrane is attached in the seams using fasteners and plates or battens. Fully adhered systems are completely bonded to the substrate beneath, creating a tighter and more secure looking TPO membrane. The bonding adhesives can’t be applied below certain temperatures. However, the adhesive in fully adhered systems evenly distributes the uplift pressure on the membrane and substrate, rather than focusing it on fastening points in the seams as the mechanically attached method does. This is why fully adhered systems typically have superior wind uplift results. Conversely, mechanically attached systems are often more cost-effective and have fewer installation restrictions. Each method offers advantages and is chosen based on factors such as the building’s structure, climate, and budget.

Regardless of the attachment method used, proper installation is crucial to ensure the longevity and performance of your TPO roofing system.

Comparing TPO Roofing to Other Roofing Materials
