Our History

We are family-owned and operated. We have been roofing for about 20 years and in 2018 we decided to take our talents directly to consumers. After servicing the industry as a subcontractor a father-daughter duo decided GreenCal Construction would provide customers with a great product and service at fair prices. GreenCal Construction is Fullerton and Southern California’s preferred roofing and exterior construction company. We service both residential roofs and commercial roofs.
