CSI Architectural Metal was brought into the project during the design-assist phase, where we worked closely with the architect and project team to engineer many of the sheet metal details before fabrication began. Our involvement included developing constructible standing seam details, coping transitions, roof edge conditions, gutters, rake flashings, and installation sequencing to ensure the architectural vision could be successfully executed. The mock-up drawings illustrate many of these engineered details and installation sequences developed for the project.
The architect selected Rheinzink for the roofing system. During the design process, CSI also proposed
terne-coated stainless steel as an alternative because of Malibu’s demanding hot, dry marine environment. Based on our experience, terne-coated stainless steel generally offers superior long-term durability in these conditions while maintaining the natural appearance architects often seek.
Ultimately, the design team elected to proceed with zinc, and CSI fully supported that decision by fabricating the custom roofing components and providing installation consulting throughout construction.
VNSM performed the installation, delivering a high-quality installation that has stood the test of time.
Approximately
13 years after completion, recent site photographs show the zinc has developed a beautiful natural patina. Aside from localized cosmetic wear in a few exposed areas that can be addressed through routine maintenance, the roofing system continues to perform well. The building’s location and setback from the Pacific Ocean appear to have contributed to the roof’s successful long-term performance.
This project highlights CSI Architectural Metal’s collaborative approach—providing engineering expertise, constructability reviews, fabrication, and installation support while respecting the architect’s material selection and design intent. The result is a high-quality architectural metal roof that continues to perform successfully more than a decade after installation.
