Our Mission

To be the industry standard by which quality in roofing is compared, where the value we provide our customers is not only measured by our workmanship, service, timely completion and profitability on jobs, but also by our honesty, integrity, enduring relationships, and our unwavering commitment to the safety of our employees, and to the occupants of the buildings upon which we work.

Our History

San Marino Roof Co. Inc. opened in 1959, serving the greater Los Angeles area.  San Marino Roof quickly established itself as a top roofing contractor, completing many of the major Los Angeles building projects.

In the early 1980’s Don Banks (President, 1979-2008) relocated the company to the Orange County area. Throughout the following years, San Marino Roof continued to build its reputation as a preferred roofing contractor with many well established general contractors.  San Marino Roof is also a select roofer for many of the high-end retail centers in Los Angeles, Orange County, and the Inland Empire.

Since 2008, Greg Banks has continued to lead San Marino Roof in the continuation of our commitment to not only quality service, but forward-thinking utilization of new technologies for the next generation of roofing needs.

San Marino Roof’s Project Management staff possesses over 100 years of combined experience, and continues to strive to be “on top” of all the current and new roofing system technology.  Utilizing trained and qualified workers, through the Union Roofers Local 220, San Marino Roof provides training, skill, safety and confidence on all projects, regardless of size.

San Marino Roof Co. Inc. highly values its established long-term relationships, and we look forward to providing your company our experience and expertise in solution of your roofing system needs.
