About Marin County Civic Center Roof Replacement

The roofs of the Marin County Civic Center are one of the most important character-defining features of the building, including their forms, distinctive color, and decorative ornamentation. Roof leaks have been present since the building was constructed and have continued in various locations throughout its life. A variety of repair techniques, products, and reroofing projects had previously been utilized to attempt to mitigate the leakage problems.

The firm began with a peer review of a previous roofing rehabilitation feasibility study. The firm then oversaw the preparation of mock-up installations for three recommended roofing systems, performed adhesion testing, and assisted with analysis and testing of the colorfastness of each material based on accelerated weathering tests.

The project involved complete removal of existing roofing systems; removing, refinishing, and reinstalling the historic metal fascia; and installing a fluid-applied elastomeric roofing system which was custom-colored the building’s distinctive “Marin Blue.”
