Flat Roofing

He saw an opportunity to develop a hard worker, with the skills to learn and provide customers a professional experience on all roofing construction aspects.

Five years later, as the roofing industry moved to single-ply systems, Alan became the youngest foreman at Black Roofing Inc., supervising 8 to 10 man crews. In 2003, after a short time in the service department as a technician, Dan Zahtila and Tim Black gave Alan the opportunity to move into a larger leadership role as Commercial Superintendent; overseeing multiple re-roofs and new construction projects from set-up through final completion. Since that time Alan feels blessed to have the incredible resources at Black Roofing in his fellow co-workers and supervisors.
