Single Membrane Roofing

 

Twin City Roofing uses 3 different types of single ply systems.  All of these systems are applied in a single layer of membrane.

EPDM, (Ethylene Propylene Diene Monomer), is commonly referred to as rubber roofing.  It is the most commonly used of the 3 systems.  EPDM withstands the extreme temperatures of our region and remains flexible in order to accommodate the effects of expansion and contraction created by temperature changes.  EPDM is available in 45, 60, 75 and 90 mil thicknesses.

  • Ballasted systems have all the components, insulation and membrane, loose laid over the deck or existing roofing.  It is then covered with a layer of gravel to hold the entire system in place.
  • Fully adhered systems are installed by fastening the insulation to the roof deck with either fasteners or adhesive.  The roof membrane is then laid into a layer of adhesive which holds the membrane in place.
  • Mechanically fastened systems are similar to the fully adhered system as they have no ballast.  The insulation is fastened to the deck.  A reinforced membrane is used in this application as the fasteners securing the membrane in place penetrate the membrane at the seams.  The following sheet covers the fasteners which eliminates any exposed fasteners.
  • Metal retrofit systems are used to cover existing metal roofs.  The flutes of the existing roof are filled with insulation.  Another layer of insulation or a cover board are installed next.  A fully adhered membrane is most commonly installed over the insulation.

TPO, (Thermoplastic Olefin), is a membrane that is heat welded together at the seams.  The material is available in 45 and 60 mil thicknesses.  It is most commonly installed as a white membrane although it is available in tan or gray.

  • Fully adhered systems are installed by fastening the insulation to the roof deck with either fasteners or adhesive.  The roof membrane is then laid into a layer of adhesive which holds the membrane in place.

PVC, (Polyvinyl Chloride), is a membrane that is heat welded together at the seams.  PVC is more resistant to greases, oils and various other chemicals than the other membranes.  It is commonly used on restaurants or buildings that have harsh emissions.
