The Next Generation of Roofers

Growing up in a roofing family, our owner and operator brings a wealth of experience to the table. With years of hands-on experience in the roofing industry, she guides our team of professionals and understands the unique challenges and requirements of residential and commercial roofing projects.

Whether it's a single-family home, apartment complex, large industrial facility, or small business establishment, GreenCal Construction has the knowledge and expertise to handle diverse roofing needs. Every roofing and exterior project is unique, and there's no one-size-fits-all solution.

After thoroughly assessing your needs, we identify any issues, and recommend the most suitable materials and techniques for the job. This personalized approach ensures that you will receive roofing solutions that are both effective and cost-efficient.

Building Relationships, too

Customer service is at the heart of GreenCal Construction's approach. We prioritize open communication, transparency, and client satisfaction throughout the roofing process. From the initial consultation to project completion, clients can expect attentive service and a dedicated team ready to address any questions or concerns.

From the initial scheduling call to the completion of the project, we guarantee we will always be here if you have any questions. GreenCal doesn't view projects as mere transactions, but as opportunities to build long-term relationships with our clients. Our commitment to customer satisfaction extends beyond project completion, fostering trust and reliability for ongoing roofing needs.
