EPDM

EPDM is an extremely durable synthetic rubber roofing membrane  (ethylene propylene diene terpolymer) widely used in low-slope buildings in the United States and worldwide. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas. EPDM is available in both black and white, and is sold a broad variety of widths, ranging from 7.5 feet to fifty feet, and in two thicknesses, 45 and 60 mils. EPDM can be installed either fully adhered, mechanically attached or ballasted, with the seams of the roofing system sealed with liquid adhesives or specially formulated tape.

LONG TERM PERFORMANCE

The long-term weathering study completed recently shows that 30-Year roofs continue to perform well.

All samples were performing like new—after up to three decades in the field.

EPDM withstands the effects of various climates extremely well.

Properly designed, installed, and maintained EPDM systems can successfully withstand extreme weather cycles.

Indications that EPDM systems can approach or exceed 40 years of service life.
This state-of-the-art study of roof systems provides tangible proof of the long-term performance capability of EPDM. The study examined five roof systems, ranging from 28 to 32 years of in-field service, and concluded that all of the systems examined were still performing as intended. In fact, the study found that all of the samples were essentially performing “like new” with physical characteristic properties above or just below the minimum characteristics of newly manufactured 45-mil EPDM membrane.

TPO/PVC

PVC roofing is made from two layers of PVC roof material with polyester added in between the layers to act as a reinforcement. The layers in a PVC roof include additives to make the material flexible, UV stable, and to prevent curing. By adding a layer of acrylic coating to roof membrane, a PVC roof is made reflective and repellent to dust and dirt.

Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made from polyprophylene and ethylene-propylene rubber polymerized together. It is typically installed in a fully adhered or mechanically attached system, allowing the white membrane to remain exposed throughout the life of the roof.

What are the benefits of vinyl 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.

PVC Roofs are uniquely formulated to withstand ponding water. Moisture will not pass through the PVC membrane. Ponding water will not affect the performance or warranty of Roof Systems single-ply membranes.

Heat Resistance

A white PVC  Flat Roof Membrane can reduce your energy consumption and your rising electric bills. By reflecting up to 90% of the heat that normally enters a building through the roof, an PVC Flat Roof will lower your building’s heat gain, and it might very well pay for itself over the lifetime of the install. Watch the video below from department of energy.

Fully Adhered or Mechanically Attached

Roofs are typically fastened to commercial buildings in one of two ways: mechanically attached or fully adhered (there are others but these are the most popular). Virtually all roofs—fastened through either method—sit on top of a layer of insulation that rests between the roof and a metal deck, which is fixed to the structure below. Why do you care? Because failing to match your roof’s construction with your actual needs can mean you’re paying for value you don’t actually need.

Mechanically Attached

Mechanically attached roofs are by far the most common, dominating around 80% of the market. They can be installed faster and at a lower cost. Builders like them because they can be easily inspected by the manufacturer, who can quickly validate the workmanship by verifying the fastener pattern and their proper installation.

On top of most buildings is a metal deck, then a layer of insulation, then the roof. When installing mechanically attached roofs, the membrane roll is laid down and then the screws are driven directly through the insulation boards into the metal deck below. Typically, the screws are drilled in at the edge of the membrane roll then covered with the edge of the next sheet as the rolls are successively put down. A watertight seal is then created by heat-welding the membranes together with a hot-air gun. This seals any gaps and creates a single, flat, waterproof surface.

Fully Adhered

Roofs that are fully adhered are glued directly to the insulation below. This requires the 4’x8′ insulation boards to serve the dual role of insulating and securing the roof to the metal deck, which requires far more screws. This method is more expensive, slower, and can lead to additional challenges because large quantities of glue have to be applied at exactly the right time and temperature—but only after it has dried sufficiently to achieve the right level of tackiness. A weighted roller is then used to press the membrane onto the glue on the insulation below.

Builders choose fully adhered roofs largely because of the perception that they’re more resistant to leaks. The theory is that if you get a hole in the roof, the water can’t travel under the roof membrane past the layer of glue. But in reality, the odds are high that you won’t even realize there is a hole until enough water has pooled underneath to degrade the glue that adheres to the insulation below.

If this happens, you’re in bigger trouble than if you had a leak that you knew about right away. Hidden water that accumulates unseen beneath the surface can spread, resulting in greater damage to a larger area.

Fully adhered roof attachments can also provide higher Factory Mutual (FM) wind-uplift ratings. Factory Mutual is a large insurance company that has established the standards for commercial buildings, even for buildings that don’t use their insurance. While it’s true that fully adhered roofs have a higher FM wind uplift rating, it shouldn’t be the priority in much of the U.S. outside of coastal or high-wind areas.

Mechanically adhered roofs dominate the market for a reason—but fully adhered roofs are still popular for buildings in certain locations with specific needs. Talk to us to determine what is right for your building based on these criteria.
