Project Scope of Work:

  • Met with the owner's representative to determine the features of the new roof system and a scope of work that meets with the client's needs.
  • Installed thermal insulation and cover board all adhered in cold adhesive to the high performance cold fluid applied vapor barrier over the concrete deck.
  • Installed two plies of heat welded modified bitumen membrane in field and base flashing of the roof.
  • Conducted a water test to check for leaks.
  • Installed over the membrane retainage drain fabric, filter fabric.
  • Per the architect's design growing medium and sedum plants or high strength concrete walk pads on pedestals were installed over the roof membrane.

Project Intent:

  • The original building was circa 1845 Williams-Brown House and was relocated to its current location in 1987. This is a historical preservation project which was built to be environmentally friendly by obtaining a LEED® Silver Rating under the LEED® System Version LEED NC 2.
  • The intent was to design and install a vegetated roof that would expand the public space for the visitors and provide a highly reflective paver system durable enough to withstand pedestrian traffic. The space provides an additional source of income for special event leasing. It was one of the main focuses of the buildings energy design and is an incremental part of the rain water management system.
  • An Energy Star Rated cool roof membrane was used for areas of the roof that are instrumental to the Rain Water Harvesting system.
