EPDM Roofing Systems

The EPDM (ethylene propylene diene terpolymer) single-ply rubber roofing membrane has been an appealing choice of the low-slope commercial roofing industry for over 40 years.The number one roofing choice of architects, roof consultants and contractors for both new construction and replacement roofing projects according to market surveys from Building Design and Construction, and Roofing/Siding/Insulation magazines, and the National Roofing Contractors Association (NRCA).
  • Over 1 billion square feet of new roof coverings in the United States annually.
  • More than 500,000 warranted roof installations on 20 billion-plus square feet.

Successful Track Record of Overall System Performance & Sustainability

EPDM has gained industry-wide acceptance and respect by providing immediate and long-term roofing solutions. As environmentalists and code regulators place more emphasis on the sustainable performance of building materials, EPDM continues to be the roofing material that stands the test of time. Characteristics that contribute to EPDM's overall system performance include:
  • Cyclical membrane fatigue resistance
  • High resistance to ozone, weathering and abrasion
  • Flexibility in low temperatures
  • Thermal shock durability.
 

TPO: Thermoplastic Olefin or Polyolefin

TPO membranes are single-ply roof membranes constructed from ethylene propylene rubber. They are designed to combine the durability of EPDM rubber with the proven performance of hot-air weldable seams. They have been tested as having excellent resistance to ozone, are algae-resistant, environmentally friendly and safe to install. The material's manufacturers are so confident in properly welded seams that the material is sometimes advertised as a monolithic (seamless) roof. Seam strengths are reportedly 3 to 4 times those of EPDM's adhesive and tape seams.

TPO is highly resistant to tears, impacts, and punctures with good flexibility to allow for building movement. TPO's are available in white, light gray, and black with thicknesses of either 45 mils (.045") or 60 mils (.060"). The width of the membrane depends on the manufacturer but they usually come in widths of six to six-and-a-half feet and are one-hundred feet in length.

TPO membranes are installed fully-adhered, mechanically-attached or ballasted. Fully-adhered means that the roof is "glued" to the substrate using a special adhesive. What actually happens is the glue creates a chemical bond with the membrane. Ballasted simply means the membrane is loose laid over the top of the roof, sealed at all penetrations and around the perimeter, and then a ballast is put on it to hold it in place. Ballast usually consists of smooth, round, river rock 2" - 3" in diameter and is applied at a rate of 1,000 to 1,200 pounds per roof square (100 sq. ft.). Sometimes concrete pavers are used in their place. These average 20 pounds per square foot. Mechanically-attached membranes are those that use some type of special screw-type fastener to secure it. The type of fastener will depend on the type of substrate but all fasteners are generally screw-type fasteners.

Properly installed TPO roof systems have service lives ranging from about 10 to 20 years, depending on the type of installation. Full removal of the existing roof, the amount of slope the roof has, weather conditions, as well as several other criteria contribute to the longevity of a roof's service life. Typically, if you remove an old roof down to the deck before installing a new one, then the new roof will last longer. Also, the steeper the slope and the less severe the weather conditions, the longer a roof will last. High winds and hail can do a roof in rather quickly.

Foam Roofing Systems (SPF)

SPRAYED POLYURETHANE FOAM (SPF): Spray foam roofing starts out as two liquid components - an isocyanate, known as the "A" component, and a resin (or polyol), the "B" component. When the liquids are mixed at a one-to-one ratio, a chemical reaction occurs and the mixture expands 20 or 30 times forming a solid, monolithic (seamless), closed-cell, fully-adhered roof system that provides excellent water-resistance and thermal insulating abilities.

SPF adheres to just about everything so it can be installed over concrete, wood, steel, and most existing roof systems (EXCEPT APP MODIFIED BITUMEN!) which saves on the expense of roof removal and landfill fees. SPF mechanics can spray apply a tapered roof system with the foam which eliminates the need for costly tapered insulation systems. The cants and vertical wall terminations are also spray applied making them an integral part of the roof system and minimizing additional component costs.

Long term energy savings.

Density of SPF is important when it comes to strength and Thermal Resistance. Obviously, higher density means increased strength and higher R-value. Most SPF roofs have densities ranging from about 2.5 pounds per cubic foot to 3 pounds per cubic foot. Three pound density foam has a compressive strength of about 50 psi and an R-value of 7.14 installed and 6.86 aged (these numbers may vary slightly depending on the foam manufacturer). Here's an example of how well a good SPF roof insulates. A school district in southern California had recently installed some new, one-room relocatable classroom buildings. During the late spring and early fall, these classrooms were using their air conditioners an average of 50 minutes every hour. The school district installed foam roofs on some of these classrooms in order to see if it would provide an energy savings. The roofs consisted of three pound density foam, 1.5 inches thick with an acrylic coating system. The air conditioner usage was cut down to fifteen minutes every hour. That's a fifty-eight percent savings on energy costs.

Does this mean an SPF roof pay for itself? Absolutely! Texas A&M studies indicate that an SPF roof in Texas and other southern climates can pay for itself in approximately four and a half years.
