Medical Centers Case Study Aduddell understands the very special demands from its valued medical center clients. We have years of experience in working with hospitals from coast-to-coast, which has given us the insight to provide quality roofing services in an environment where no type of flame can be used on top of the roof. Also, we understand that any type of hot asphalt cannot be used because of smell. Consequently, we have special expertise in using a cold applied system on hospital projects.
