Flat Roof Systems


Flat roofing is a necessary aspect of construction industry, something most larger buildings could not have been built without. However, flat roofing is an intricate field in construction, and very few roofing contractors can properly specify and install an appropriate roofing material, which would keep the building envelope water-tight, provide energy savings appropriate for our location and local climate conditions, as well as being a financially feasible option for the roof owner. Adirondack Roofing is an expert in this field and can provide viable solutions for your flat roofing project! Call today for a FREE evaluation and estimate of your flat roofing needs!


EPDM Flat Roofing


Ethylene Propylene Diene Monomer (EPDM) is durable and resistant to general wear and tear and an excellent material for low slope roofing applications. EPDM roofing is a synthetic rubber that acts as a roofing membrane special for flat roofs. The EPDM roofing membrane is versatile and allows for many installation options.


  • Developed in America in the 1960’s, EPDM roofing is designed to exhibit superior flexibility, high strength, and outstanding weathering in practically all climates. The EPDM roof will not crack, split, or peel, and is completely resistant to atmospheric pollution. EPDM roofing is also environmentally friendly, and is unaffected by UV light and ozone. The elasticity of EPDM roofing allows it to elongate to over 300% to accommodate temperature cycling and building movements. An EPDM roof system has a life expectancy of about 20 years, during which next to no maintenance is required.
  • EPDM roofing comes in all sizes and can be installed in one piece, eliminating the problems associated with parting joints that cause many roof leaks and other common problems associated with flat roofs.
  • Because EPDM roofing can be installed in one piece, its installation requires minimal seaming. We offer EPDM roofing installation services for all kinds of low slope and flat roof applications. Additionally, EPDM roofing has a low life cycle cost, as it requires little maintenance.


TPO Flat Roofing


TPO (Thermoplastic Olefin or Polyolefin) membranes are single-ply roof membranes constructed from ethylene propylene rubber. They are designed to combine the durability of rubber with the proven performance of hot-air welded 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 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.
  • 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.


Composition of “Modified” Bitumen Flat Roofing


Modified Bitumen is a roofing membrane consisting of asphalt and plastic or rubber polymers, and is therefore widely considered an evolution of asphalt built up roofing. Modified bitumen displays the built in redundancy of asphalt built up, as well as the UV resistance and flexibility of a modified membrane. This is because the polymer mix used allows the asphalt to take on its most beneficial qualities. Like with tar and gravel roofing, modified bitumen requires a surfacing material, and the most commonly used are factory applied mineral blends, and gravel. Modified bitumen is generally applied using a heat application process that melts the seams together to create a seal, yet sometimes a cold adhesive application system is used.
