Our Story

Welcome to ADS Sheet Metal, a story of ambition, family, and exceptional craftsmanship. Our journey began over 20 years ago when our founder and owner, Alim Diaz, immigrated from Guatemala with a vision to build something enduring. Rooted in family values and a strong work ethic, Alim began his venture by employing members of his family, each bringing their unique skills and dedication to the table.

Over the years, this small family endeavor has blossomed into a thriving business, now boasting over 200 dedicated employees. Our growth is a testament to our commitment to quality and our deep understanding of the sheet metal, gutter, and metal roofing industry. ADS Sheet Metal has become the leading name in these sectors across more than 41 cities within the Greater Los Angeles area, thanks to our relentless pursuit of excellence and customer satisfaction.

Our expertise spans a broad range of services, from intricate sheet metal work to robust metal roofing and efficient gutter systems. Each project we undertake is infused with the same level of care and precision that has been our hallmark since the beginning. We take pride in not just fulfilling, but exceeding our clients' expectations, whether it’s a small residential job or a large commercial project.

The heart of ADS Sheet Metal lies in our people – a diverse team of skilled professionals who are more like family than employees. Our shared vision and values have helped us navigate the challenges of a competitive industry, turning obstacles into opportunities for growth and innovation.

As we celebrate over two decades of service, we reflect on the journey that has brought us here. From Alim Diaz's courageous start in a new country to becoming the #1 Sheet Metal, Gutter, and Metal Roofing company in the region, our story is one of resilience, unity, and unwavering commitment to craftsmanship.

We look forward to continuing our legacy of quality, innovation, and family-centric values for many years to come. Thank you for considering ADS Sheet Metal for your needs – where we treat every project as if it were for our own home.
