At the request of the in-house design team, OAS specified removal of an aged clay tile roof system to facilitate installation of new ice and watershield membrane followed by the installation of new copper flashings, valleys, base flashings, and gutters. In order to access all areas, scaffolding and safety apparatus were erected as fall protection. The final phase of the project included installation of new treated lumber ridge poles followed by the installation of new Ludowici glazed Spanish tile.

As the facility was fully occupied and access could be gained only from the east elevation front entrance of the facility, it was imperative that great care was exercised in protecting employees and visitors of OAS.
