COATINGSPRO MAY 2016 63 "We coordinated things so we could utilize them at the same time," Kohls said. Working together also beneftted the profle of the roof, and by extension, the client. "We could make sure we had a good transition between the roof and chimneys, so it wouldn't leak," Kohls said. According to him, the working relationship went very smoothly. "On our frst day of the project, it was the fnal day they needed to remove the last of the stone on the last chimney, so we helped them with a few things there," Kohls said. "Ten as soon as we fnished, they were there that next Monday to get started putting the stone back on." Prior Engagement With the chimneys cleared out, Kohls and his crew were ready to tackle the job. Tey started by installing safety perimeters and fagging around the rooftop. He also had a full-time safety monitor while the crew was working. Te crew also put to use the Genie boom lift that Kohls had rented with Aspen Tile. Te roof was 40 to 50 feet (12.2–15.2 m) above the parking lot, which was too far for a ladder to reach. The crew from Kohls was ready to get the foam going once the area was prepped. "After all the gravel was removed, we started the spray foam application," Kohls said. Coordination was a key on this rooftop recoat project. The Kohls crew had to coordinate their part of the project with the replacement of the chimneys and that company's crew.
