    PVC Roof Installation

    The PVC roof has been widely adopted by commercial, industrial, and institutional buildings for six decades.

    Its prominence has been attributed to longevity, ability to withstand severe weather, and cost-effective installation and repair.

    If your roof was recently damaged or is approaching its life expectancy, a PVC roof installation delivers wide-reaching benefits.

    These are things to consider about PVC membrane roofing systems.

    PVC Roofing Details

    What is PVC Membrane Roofing?

    A PVC roof employs a single-ply PVC roof membrane consisting of two layers of specially-formulated vinyl bonded to a polyester reinforcement scrim layer.

    The PVC membrane roof is often white or light-colored to deflect intense UV rays and improve energy efficiency.

    Everyday people typically think of PVC as the hard plastic pipes used in plumbing. Called “PVC” by industry insiders, the term refers to “polyvinyl chloride.”

    This synthetic polymer can be manufactured as a rigid or flexible construction material.

    A PVC roofing contractor utilizes flexible products to cover a low-slope or flat roof with layers that last upwards of 30 years.

    A PVC roof installation begins by laying down a layer of insulation board over the roof deck.

    The more commonly used products include ISO or EPS foam boards that possess an R-value between R4 and R6 per inch of insulation thickness.

    This essential PVC roofing element minimizes energy losses and helps keep utility costs low.

    • There are three basic ways a PVC membrane roofing installation can be accomplished. These involve fully-adhered materials, mechanically fastened, or an induction welded PVC roof.
    • Fully Adhered PVC Roofing: The PVC membrane roofing material is essentially glued directly to the existing substrate using a strong commercial adhesive. This method usually comes into play when a structure cannot easily hold fasteners or property owners wish to minimize penetrations into the roof deck.
    • Mechanically Attached PVC Roofing: This process involves employing heavy-duty screws and plates to secure the PVC membrane roofing materials in place. A preferred choice in areas prone to severe weather events such as hurricanes and tornados, an attached PVC roof withstands high winds.
    • Induction Welded PVC Roofing: This process involves heating equipment deployed to the PVC membrane roofing above metal plate locations. The induction welding tool sends electric pulses that heat the metal plate, causing the materials to cling to it. An induction welded PVC roofing system requires fewer fasteners and tends to be less labor-intensive than others in its class.

    In all three processes, the seams of PVC membrane roofing sheets are welded together to form a cohesive barrier against the elements.

    It’s also important to understand that PVC membrane roofing materials are relatively thin compared to other systems. Manufacturers produce products that include thicknesses from 40 mil (0.04 inches) to 90 mil (0.09 inches). Common membrane thicknesses are 60, 80 or 90 mil.

    A large number of PVC roofing installations use white materials to reflect the sun’s rays. However, alternative colors such as gray, tan, brown, red and green are available. Niche materials can emulate the appearance of roof shingles and certified products are fire-resistant.

    Welding TPO Membrane Seams

    Types of PVC Roofing Membranes

    This class of materials has been popular in low-slope and flat roof installations since the 1960s.

    The rise of PVC roofing systems was driven by cost-effective installation, reduced weight on structural elements, and the ability to withstand inclement weather. These are commonly employed types.

    Standard PVC Roof Membrane

    Standard PVC roofing membrane comes as a single-ply product.

    Designed to deliver long-term heat reflection and water damage protection, industry-leading PVC membrane roof materials are Energy Star rated.

    A standard PVC roofing system is generally comprised of two layers of membrane, with polyester in the middle for reinforcement.

    Additives increase flexibility and standard PVC can usually be installed using fasteners or adhesives.

    PVC KEE Roof Membrane

    When PVC roof membrane materials are manufactured, rigid elements must be modified to make them more flexible.

    The liquid plasticizers used to make this happen can evaporate over time. That’s why Ketone Ethylene Ester (KEE) was introduced.

    KEE PVC membrane roofing products employ a concentrated polymer additive that exceeds many liquid plasticizers.

    Essentially, a PVC KEE membrane maintains its elasticity longer and adds to a roof’s life expectancy.

    This class of PVC membrane roofing products can also be used in conjunction with asphalt and reflects the sun’s rays efficiently over time.

    Fleece Backed PVC Roof Membrane

    By securing high-quality fleece elements to the bottom of a PVC membrane roofing product, it gives a low-slope or flat roof additional support.

    Fleece-inclusive materials are easier to install because they can be rolled out directly on the roof.

    This process reduces labor costs while delivering an effective protective PVC roofing layer.

    A PVC roof installation that leverages fleece-backed products enjoys the flexibility of being secured by adhesives or fasteners.

    Buildings in an area prone to high winds often prefer the adhesive PVC roofing installation for its resistance to severe weather storms.

    It’s important for property owners and managers to know that standard and KEE products can also be selected with a fleece backing.

    The decisions surrounding the products used in a PVC roof installation are largely driven by architectural design, structural integrity, and weather conditions. A PVC roofing expert can walk you through the process and answer any questions.

    TPO Roofing System


    Components of a PVC Roofing System

    A PVC roof involves more than a simple membrane.

    Each PVC roofing installation requires layers of materials designed to serve a specific purpose.

    Versico TPO Membrane Roof SystemsThese include the following.

    • Roof Deck: The roof deck is the layer of hard material secured to structural supports. It provides a foundation for other PVC roofing elements.
    • Insulation: Each PVC roof employs a layer of insulation that typically rests on the roof deck. The thickness and type are driven by regional weather patterns and energy efficiency.
    • Fasteners and Plates: The use of fasteners and plates provides a secure connection between the membrane sheets and roof deck.
    • Bonding Adhesives: Adhesives may be the best way to install a PVC roof, based on weather conditions, and other factors. Adhesives sometimes prove a suitable choice in places that frequently experience windstorms.

    It’s also essential to note that flashing and sealants are used where a ventilation pipe, HVAC unit, or parapet extends through the roof.

    A high-quality PVC roof installation calls or experienced technicians to properly seal and flash around a parapet to prevent moisture penetrations and water damage.

    Benefits of a PVC Roofing System

    The PVC roof remains a popular choice for a commercial, industrial, and institutional building with a low-slope or flat roof.

    That’s because a PVC roof provides property owners and stakeholders with lasting benefits, such as the following.

     Cost-Effective Installation

    A PVC roofing system ranks among the least labor-intensive options. Reducing the number of work hours it takes to diligently install a PVC roof lowers the cost to property owners.

     PVC Roof Repair is Simple

    A flat roof allows PVC repair technicians open access to areas that may have been impacted by hailstone strikes, falling debris, or an extreme weather event. Access and easy-to-apply repair materials minimize cost and maximize emergency roof repair response.

     Durable and Weather Resistant

    One of the true tests of any roofing system stems from its ability to withstand temperature swings and severe weather. A PVC low-slope or flat roof provides natural resistance to high winds. When properly secured by an experienced roofing contractor, the surface area deflects high winds. Even if hail the size of baseballs makes impact, PVC roof repairs can be made quickly to prevent water seepage.

     Maximize Energy Efficiency

    The PVC membrane roofing materials all serve an energy-related purpose. White and light-colored surface areas reflect harsh UV rays to minimize the need for air conditioning. The insulation layer traps heating and cooling energy inside the facility.

     PVC Roof Lasts Decades

    For a PVC roof installation to achieve its maximal life expectancy, three things are necessary. An experienced and certified roofing contractor is required to ensure the installation is conducted with precision. Loose fasteners or inadequate flashing result in unnecessary damage.

    The climate where the building is situated also matters. Areas prone to hurricanes and hailstorms may require ongoing repairs. Lastly, the type of installation and PVC membrane roofing materials must correctly meet climate and other expectations. When everything is in place, a properly maintained PVC roof can last 30 years or longer.
