GRS undertook a project re-roofing a large commercial unit with an EPDM roofing system. Everything was brought in and installed with exacting detail from the FR boards to the metal flashings and detail work.Roof Report: August 5 2015:
The crew arrived on-site at 7:00am and began cutting and laying in the FR board in preparation for this EPDM roof installation at this commercial property. Before all of the FR board was put down, four gumboxes (plastic pans) had to be removed and the pipes they surrounded required grinding down. The grinder ran out of discs, so one member of the team left to replace them while the others began putting down the first run of the EPDM rubber. Upon the departed member's return, the two remaining pipes were removed and rubber was cut to fit around the extrusions and glued into place. Around 3:00pm, rain clouds began to roll in and threatened the end of the work day. The FR boards were covered and cleaned, covered with rubber, and weighed down to waterproof the roofing system for the night.

Team arrived on-site again for 7:00am and began to lay board down, using Duratec to seal it. After the board was laid, they began installing the EPDM, taping and sealing as they went. Upon finishing the last roll of rubber for the day, one member began sealing and waterproofing penetrations (pipes, extrusions, etc) . The remaining members put the overnight seal on the unfinished work. Day's work resulted in 2580 square feet of EPDM roofing installed.
Roof Report: August 8 2015:
After a safety briefing and detailing what materials were required to finish this job, the crew started working at the far wall on the west side of the building. Three members of the crew worked to finish laying in the rubber and bonding it to the board (completing seam work as they went along). Two team members worked on the detail work remaining on the east side of the building, completing that portion and ensuring that the metal siding application can be done next. For the day, 500 square feet of rubber was laid and 95% of the seam work was finished.
Roof Report: August 9 2015:
This day saw the completion of all the required seam work and removal of most of the rooftop garbage. The patchwork and detail work is nearly done in addition to the metal stripping around the perimeter of the building being put back on. The crew believed that the following day would see the finalization of the project, contingent on some materials being brought to the site. The smaller roof (separate level) is entirely prepared to be roofed over, which is believed to take eight man hours (in a two-man team) to wrap up. A bin will need to arrive on Tuesday to remove all of the waste from the site.
Roof Report, August 11 2015:
Today was the last day of the project. The GRS team completed the detail work, patching, flashings and the lower roofing's EPDM system. In addition to the above, a new drain was installed and the garbage was cleaned away from the building.
