EPDM

single ply roofing

  • EPDM (ethylene propylene diene terpolymer), also often referred to as “rubber roofing” is in most applications, the least expensive single ply membrane to install.
  • Reliable and durable roofing membrane that has been in wide use since the 1960s.
  • The seams of EPDM must be sealed with liquid adhesives or specially formulated adhesive tape.
tpo

TPO

single ply roofing

  • An economical membrane material made with special polymers that give it great flexibility in a variety of weather conditions, including colder climates.
  • Easy to install and the most environmentally friendly of the single-ply membranes.
  • Seams are heat-welded so that, once installed, it becomes unified membrane.
pvc

PVC

single ply roofing

  • Less economical than TPO, PVC has a longer track record of performance.
  • Naturally fire-retardant and highly UV resistant.
  • Seams are heat-welded so that, once installed, it becomes unified membrane.

MODIFIED BITUMEN

  • Modified Bitumen Roofs are economical, tough, built-up, layered roofs that use factory-made rolls of roofing material, layered on top of one another.
  • In a factory-controlled environment, rolls of fiberglass mat are impregnated with either plastic-modified or rubber-modified bitumen.
  • The uppermost layer is usually topped with mineral granules to provide protection from Sun and mechanical damage.
BUR

BUILT-UP

single ply roofing

  • Multiple layers of roofing materials provide redundant protection against mechanical damage and they can be easily patched and repaired.
  • Built-up-roofs or BURs have been popular in the United States for over 100 years, and are still found on a large number of flat roofs today.
  • Built-up-roof systems are composed or “built up” using alternating layers of bitumen (asphalt, coal tar or synthetically modified cold-applied adhesives) and reinforcing felts (tar impregnated fabrics).

LIQUID APPLIED ROOFING

  • Liquid-applied roof coatings are waterproofing coatings used in re-roofing situations.
  • Can be applied, hot or cold, over the top of existing membranes.
  • The most common system is the hot-applied rubberized-asphalt applied over uncured neoprene, polyester fabric or fleece reinforcing.

METAL ROOFING

  • Hydrostatic Roof Systems – Roof panels are designed to operate in slopes less than 3:12.
  • Hydrokinetic Roof Systems are water-shedding panels and require a slope greater than 3:12 (25 percent).
  • Metal roofs are more efficient at shedding rainwate. It can also withstand impact from hailstones and airborne debris and is less likely to get punctured
