  • Liquid Membranes
    Applied in liquid form to create a seamless, UV resistant, and waterproof membrane that conforms to any penetration shape
  • Modified Bitumen Roofing
    Designed for buildings with low-slope or “flat” roof structures
  • Build-Up Roof (BUR)
    Traditional design consisting of multiple layers of bitumen and reinforcing materials
  • Single Ply Roof Systems
    Single-ply roofing membranes are mechanically fastened to layers of insulation  for durability
  • Inverted Roof Membrane Assembly (IRMA)
    Protected membrane roof where the insulation is installed on top of the membrane
  • Metal, Tile & Shingle Roofing
    Durable and aesthetic options for specific roofs
  • Green Roofs
    A planted or vegetated area on a flat or sloped roof with the goal of increasing energy efficiency and lowering carbon footprints

As your roofing experts, our team of qualified engineers will investigate the roof, prepare thorough specifications and drawings with customized details that fit your site, and suggest how you can optimize your new roof, possibly by installing a green roof or a VOC compliant roofing system. Surrounding problems at parapets, bulkheads, railings and other critical locations that may need repairs prior to installing the new roof will also be noted and documented by one our our Sr. Project Managers.

Our team is present throughout every stage of your roofing project. From bid leveling to the monitoring of construction, we not only assist in selecting a contractor who is the best fit for your project but ensure they maintain complete adherence to our design and contract requirements.

Infrared Scans

With the use of Infrared Thermographic Technology and non-destructive techniques, our team can easily identify problem areas during roof and leak investigations. This enables us to efficiently and accurately solve the problem before water and moisture cause extensive damage to the building’s structure.
