Ridgeworth Roofing had handled preventative maintenance and repairs on the main roof of the 36-story high rise, but the roof was past life expectancy and was experiencing periodic leaking. Building ownership requested a roof system with a long-term warranty that would meet the building’s needs. Ridgeworth worked with Polyglass USA on a specification that would meet the requirements of both the building owners and the roof manufacturers, including fluid-applied flashings along with the installation of the bright white Polyglass modified sheet. The building offered an interesting safety challenge, as the roof perimeter was more than 500 feet in elevation with a standard low-profile edge detail. To protect the crew on the roof and the public on the city sidewalks below the work area, Ridgeworth had its subcontractor, Switch Rail Safety Systems, install a full guardrail system with a debris screen.
