Expertly roofing Greater Los Angeles for decades

We are family-owned and operated, and have been roofing for over 20 years. In 2018, we decided to take our talents directly to consumers. After servicing the industry as a subcontractor, a father-daughter duo created GreenCal Construction to provide clients with a turnkey exterior remodeling experience.

GreenCal Construction is Los Angeles, Orange County, and Southern California's preferred roofing and exterior construction company. We are committed to offering the best products at fair prices, all while providing our professional expertise and high-level service.
