Metropolitan designs, installs, and repairs all types of roofing systems and plaza deck membrane systems...from conventional built-up roofs to single ply roofing systems, and from historic roofs to EPDM membrane systems. Our firm has extensive expertise in the installation of historic slate and copper roofs. Metropolitan handles the fabrication of architectural copper roofing detail and metal roofing systems in-house, thus assuring quality workmanship and the utmost efficiency in the installation of these types of roofing projects.

Our firm has a highly experienced project management team to assure that roofs that have been prone to water infiltration are fully evaluated and reconstructed to be watertight. In plaza deck reconstruction, Metropolitan is skilled in the installation and repair of all types of plaza deck systems, including the installation of containment grid systems where appropriate.

Known industry wide for its evaluation of roofing/water infiltration problems and the effective resolution to these problems, Metropolitan is a single resource for sealing the building envelope. Every roofing system should be inspected regularly so that any water problem is resolved before it becomes major. Toward that end, we offer clients routine maintenance and service programs to assure the integrity and longevity of the structure's roof.

Project Size
6,000 s.f. Plaza Deck Reconstruction

Project Background
The project entailed the removal of the existing plaza deck pavers, and overburden, as well as the installation of a new waterproofing membrane and new plaza deck pavers.

Project Description
The plaza deck at the Astrophysics Department facility at Harvard College is also a courtyard for the science building. It has very difficult access which proved to be a challenge that was solved by Metropolitan prior to project commencement. The existing plaza deck membrane system was located under concrete pavers. The reconstruction project necessitated removing the over-burden, consisting of 2' X 2' concrete pavers and 12" of drainage fill. Since the logistics and access were difficult, a system had to be devised and implemented so as to handle the material removal efficiently.
