Governor’s Office of Emergency Services Roofing

When California’s Governor’s Office of Emergency Services complex began experiencing persistent leaks and water damage, they partnered with Salas O’Brien to replace the worn-out roof membrane. Our team removed the existing Thermoplastic Polyolefin (TPO) membrane and installed wet insulation and gypsum cover boards for increased wind resistance. In addition, we removed and reflashed copings, edge metal, mechanical units, windows and doors, skylights, and wall claddings to minimize potential leak paths above the roof.

We collaborated closely with architects, contractors, membrane manufacturers, and state officials throughout the project to address any issues. And we monitored applications part-time and established strong relationships with on-site state inspectors, ensuring a seamless and successful project.

As a result, the roof passed all specified uplift, water, and winter rain tests with flying colors, demonstrating its strength.
