Roof Designs and Repairs

Program Development Study
San Francisco, CA
Interactive Resources designs and specifies roofing systems for all new buildings and major renovations designed by our firm. In addition, we have provided evaluation, construction documents and contract administration for a large number of projects principally involving roof replacement or repair.

We have developed an in-depth technical knowledge of roofing design and systems over our years of experience. Our firm is often selected to provide services for challenging re-roofing projects where innovative solutions are required to correct design and/or construction deficiencies found in the original construction.

Our completed projects include the successful application of a wide range of roofing systems, such as conventional built-up bituminous roofing, modified bitumen, single-ply thermoplastics, and metal roofing.
