Liquid Rubber Roof on PVC/ TPO/EPDM

Membrane PVC/TPO/EPDM roofing is so far one of the most contemporary roofing solutions. The technology of mounting of an PVC/TPO/EPDM roof allows creating a seamless layer that features incredible waterproofness and insulation.

An PVC/TPO/EPDM roofing membrane is a flexible material that is produced on the base of natural PVC / TPO / EPDM rubber. For further firmness and durability, the membrane is reinforced with synthetic fibers. An PVC/TPO/EPDM roof membrane is a relatively new solution that has not yet gained so much popularity as roll roofing, asphalt, or tar and gravel. However, many people have already discovered all the advantages the PVC/TPO/EPDM roofing systems offer and use them more and more often.

In most cases, the membranes are installed onto roofs that have a slight incline. The waterproof features of the membrane and the incline help withdraw water as effectively as possible. It’s a perfect roofing material solution for Toronto as well as the entire Canada territory. It’s a great choice for a flat roof that is used as a recreational space. In case you decide to have a small summer garden on your flat roof, there is no better choice than the PVC/TPO/EPDM roof membrane.

Feel free to give us a call and we will tell you more about the PVC/TPO/EPDM rooding advantages as well as other useful details.

The Construction of an PVC / TPO / EPDM Roof

The PVC / TPO / EPDM roofing membrane is 0,8 to 2mm thick. Its small weight allows using it on any roofs without any special reinforcement. It’s easily mounted without any specialized tools and equipment. The process of installation takes twice as little time compared to any other material from the bitumen types.

As a rule, membranes are made out of several layers of material where the top layer is natural PVC / TPO / EPDM rubber, the bottom one is made out of bitumen, and all this is reinforced by fiberglass canvas. Such membranes are extra durable to mechanic influences, UV radiation, and frosts that is especially important for areas like Toronto and GTA.

BTW, these membranes are absolutely environmentally friendly.

Though the PVC / TPO / EPDM roof membranes can be installed onto any surfaces, it’s better to remove all the old roofing materials and remnants of the old water insulation. That’s why we at Royal Roofing examine roofs to determine what pieces should be removed and what can stay before getting to installing the membrane. So, if you are interested in expert roof inspection and estimation of your project, call 416-880-7625 and discuss it with our well-trained staff.

Types of Installation and Repair

The most effective way to install a membrane is to weld the pieces of the material with the help of hot air. This technology provides extra durability of the seams. It requires a special machine that gives off hot air with a certain pressure. However, flashing, openings, corners, and other places that need special attention are usually processed manually with the help of other professional tools.

It’s also possible to use adhesive tapes that have both sticky sides but in such a case the reliability of seams is much lower.

The process of repair of an EPDM roof is quite simple: it’s necessary to replace damaged parts and install new ones. It’s obviously necessary to give a lot of attention to water insulation when old pieces of the roofing materials are removed and new ones are installed. If you don’t want to remove the entire roofing to replace it with a new one, you need to be sure that the old and worn materials have been removed completely.

For this reason, it’s always better to hire professional contractors who will do everything correctly and quickly. Get in touch with us at Royal Roofing Inc. and our experienced specialists will handle all your roofing matters in the most efficient way.

PVC / TPO / EPDM is an abbreviation for Ethylene Propylene Diene Terpolymer, which is a rubber roofing membrane. EPDM has been most widely applied to low sloping commercial roofs, and is designed especially for non-residential roofing systems. EPDM is also durable, reliable and delivers outstanding ultra violet, ozone and weathering resistance.

Other characteristics include;

  • Proven Hail Resistance
  • Flexibility in low temperatures
  • High resistance to ozone, weathering and abrasion
  • Thermal shock durability
  • Superior resistance to extreme heat and fire
  • Wind uplift ratings including 1-60, 1-90, and 1-120.
  • UV resistance and flexibility pass -60 degrees Celsius


PVC / TPO / EPDM membrane offers two installation options; one being its application with a bonding adhesive and the other—loosely laying the material and then covering it with ballast weight. The second option offers a cleaner installation and eliminates the need to use traditional and heavy roofing equipment.

Moreover, membrane sheets can be up to 10,000 square feet large, making PVC / TPO / EPDM roofing much faster to install than conventional modified bitumen or built-up systems.

PVC / TPO / EPDM Longevity

As most other roofing materials, EDPM rubber has varying levels of longevity, which significantly depend on the surrounding environment. Important factors to consider include, but are not limited to the amount of foot traffic on the roof, the type of a building to which it belongs as well as its tendency to collect and retain water after the rain, which is largely reliant on the natural speed of evaporation. Generally, the lifespan of an PVC / TPO / EPDM roof ranges from 12 to 25 years. While this duration may seem shorter than some other roofing systems, PVC / TPO / EPDM’s incredibly easy reparability makes up for this shortfall in full. Even following years of the roof’s exposure to various weather conditions and other ongoing natural factors, repairs or certain modifications can be easily performed to restore the roof’s condition, guaranteeing future performance and durability.
