We are well versed in the application, maintenance and repairing of membrane and built-up roofing systems. There are a variety of commercially manufactured flat roof systems our company has experience with to meet a customer’s needs. Below are the more recognized flat roof systems and their attributes.

Elastomeric/Plastomeric Membranes

EPDM (ethylene propylene diene monomer)

Attachment methods: Mechanically attached and adhered.

  • High resistance to ozone and ultraviolet exposure.
  • Flexible even at low temperatures.
  • Resists expansion and contraction (less likely for the roof to leak)
  • Easy to locate and repair leaks.
  • High resistance to wind damage, hail, and punctures.
  • Frequently used on commercial roofing projects
  • Sustainable and environmentally responsible, material is recyclable and it reflects heat energy allowing the building to remain cooler in turn, reducing energy/cooling costs.

Thermolastic Single-Ply Membranes

TPO (thermoplastic polyolefin)

Attachment methods: Mechanically attached and adhered.

  • High resistance to ozone, ultraviolet, and chemical exposure (i.e. oils).
  • Flexible even at low temperatures.
  • Easy to locate and repair leaks.
  • High resistance to wind damage, hail, and punctures.
  • Frequently used in commercial roofing projects
  • Sustainable and environmentally responsible, materiel is recyclable and it reflects heat energy allowing the building to remain cooler in turn, reducing energy/cooling costs.

PVC (polyvinyl chloride)

Attachment methods: Mechanically attached and adhered.

  • High resistance to ozone, ultraviolet, and chemical exposure (i.e. oils). One of the most resistant membrane types when it comes to oils and chemicals.
  • Flexible even at low temperatures.
  • Easy to locate and repair leaks.
  • High resistance to wind damage, hail, and punctures.
  • Frequently used in commercial roofing projects.
  • Sustainable and environmentally responsible, materiel is recyclable and it reflects heat energy allowing the building to remain cooler in turn, reducing energy/cooling costs.

Modified Bitumen Roofing Systems

SBS (styrene-butadiene-styrene)-Asphalt modified with synthetic rubber.

Attachment Methods: in hot asphalt, cold adhesive or heat welded (adhered).

  • Flexible even in low temperatures
  • Resistant to punctures and wear and tear from foot traffic.
  • Sustainable and environmentally responsible, materiel is recyclable and it reflects heat energy allowing the building to remain cooler in turn, reducing energy/cooling costs.

APP (atactic polypropylene)-Asphalt modified with plastic.

Attachment Methods: Adhered via heat welding or cold-applied adhesive.

  • Resistant to ultraviolet and higher temperatures.
  • Resistant to punctures and wear and tear from foot traffic.
  • Sustainable and environmentally responsible, materiel is recyclable and it reflects heat energy allowing the building to remain cooler in turn, reducing energy/cooling costs.
