Ethylene Propylene Diene Monomer (EPDM)

No other roofing membrane withstands the weather like Ethylene Propylene Diene Monomer (EPDM).

Key Features

  • Weatherability / durability of the sheet — the longest lasting membrane

Additional Features

  • Flexible application:
  • Ballasted — loose-laid membrane that is held in place with stone
    Mechanically attached — secured to the roof deck with mechanical fasteners
    Fully adhered — glued directly to the roof insulation

  • Can be used on both new and existing roofs

Thermoplastics

Durable, versatile and attractive, thermoplastics are a popular choice for many reasons.

Key Features

  • Light colored
  • Reflects heat for lower utility costs and greater comfort inside
  • Attractive — aesthetically pleasing, especially for sloped applications
  • Heat — weldability

Additional Features

  • More tear-resistant than EPDM membranes — up to five times more puncture-and tear-resistant than a non-reinforced EPDM membrane
  • Much more resistant to animal fats, oils, and contaminants than rubber (EPDM) is
  • More suited to chemical situations — some can withstand significant chemical attack
  • Can be applied in the winter
  • Can offer compatible thermoplastic-clad metal flashings

Limitation

  • Less resistant to ultra-violet attack than EPDM (rubber membranes)

  • Thermoplastic Olefins (TPOs)

    Thermoplastic Olefins (TPOs) combine the unparalleled durability of rubber membranes with the superior seaming process of PVC, providing the best of both in a single membrane.

    Key Features

    • Durability of rubber combined with the strong (heat weldable) seams of PVC

    Additional Features

    • All the advantages of thermoplastics
    • Aesthetics (some limited color options)
    • Reflection (available in light-colored sheets)
    • Increased tear-resistance
    • Chemical-durability
    • Can be applied in cold weather

    Limitation

    • Relatively new technology; not market-proven yet, which takes about 20 years
  • Ethylene Interpolymer Alloy (EIPs)

    Ethylene Interpolymer Alloy (EIPs) are resistant to animal fats and chemicals — for restaurant roofing there’s no better option.

    Key Features

    • Most resistant to animal fats and chemicals of all roofing membranes
    • Best choice for restaurants
    • Proven performance — more than 20 years of market use

    Additional Features

    • Plasticizers do not leave the sheet, allowing the membrane to remain flexible

    Limitation

    • Initial cost can be high relative to other systems
  • Polyvinyl Chloride (PVCs)

    Polyvinyl Chloride (PVC) features strong seams and, because it’s resin-based, a great deal of color flexibility.

    Key Features

    • Heat-weldable seam — strongest seaming technology in the business

    Additional Features

    • Can custom mix colors to create a desired look
    • Compatible thermoplastic-clad flashings are available

    Limitation

    • UV stability can be an issue
    • Plasticizer migration can cause PVC to become rigid and crack
 

Modified Bitumen

Asphalt-based systems have been proven performers on high-traffic roofs for years.

Key Features

  • Perfect for heavy traffic areas and roofs that see a lot of abuse

Additional Features

  • Rubber compounds are added to asphalt
  • Makes the asphalt less brittle
  • Adds to the roof’s ability to withstand weather changes
  • Can be applied during colder months

Limitation

  • Ponding water can shorten the roof’s effective service life
  • May require open flame for installation
  • Odor during installation can be offensive

Cautions

  • Weak warranties—does not always require a manufacturer’s inspection

Shingles

  • We offer the leading shingles from the best manufacturers
  • Expert installation for the most demanding commercial applications

Built Up Roofs

Once the traditional approach to flat roofing in America, Built-Up Roofing Systems are enjoying renewed popularity due to significant improvements in materials, design and application techniques.

Key Feature

  • Durability. The strength of today’s composite, built-up roofing systems make them resistant to puncturing and general rooftop abuse. They are often a great choice for roofs that see a great deal of traffic.

Additional Features

  • Good life expectancy (15-25 years) if properly maintained
  • Easy to maintain and service
  • Reliable
  • Can be completed without a final coat of gravel for projects requiring a finished surface that is both smooth and ultraviolet light-reflective

Limitations

  • Limited ability to handle expansion and contraction requiring the installation of expansion joints
  • Ponding water can shorten the roof’s effective service life
  • Can emit an offensive odor during the installation process
  • Caution required during installation due to the need for an open flame
  • More maintenance is generally required
