Academy Roofing’s knowledge of sustainable technology and expertise with roofing systems and insulation was of pinnacle importance when selecting the company for this project. Not only did Academy provide complete and thorough LEED documentation for certification, it also worked with the client to provide the most feasible, affordable and workable budget.

“Academy Roofing was chosen due to the ability to meet a demanding winter time schedule and their vast knowledge of green-building industry requirements,” explains Jan Becker, architect, Bread Loaf Corp. “They ensured all products met or exceeded the LEED requirements. Academy is one of the finest roofing contractors we have had the pleasure to work with.”

The project demands included unique flashing details, raised skylight section areas and custom-designed A-framed roof sections with skylights. Varying roof surfaces meant safety was imperative, especially with respect to winter weather. Overhead crane work, steel work and protection of open edges of the building were required during construction at the high-traffic job site.

Academy Roofing provided design expertise regarding the architectural details of the varied roof sections, including custom fabrication of roof system components.
