Meet The Team

NEXT-LEVEL support and customer service. Fantastic, prompt communication and excellent product education/resources/support. These guys are the real deal. A++. ”

— Heather H.

What makes Castagra truly different from other coating manufacturers? That’s easy: our people.

Castagra employees share a unique bond (confession: we’re not above making coating puns). They’re not simply talented, innovative, engaging individuals; they’re also extremely curious.


They aren’t content with the status quo in roofing. They love breaking the mold and taking the path less traveled. They crave what’s different and new. They’re what makes our company culture so vibrant and exciting — and propels us to greater heights every day.


We proudly introduce the friendly faces of Castagra.

Tats is passionate about innovation and loves the challenge of developing great ideas that can change the world! When he’s not working, he likes to spend time with his family, and read as much as possible (mostly books about entrepreneurship and business). He’s not all business though!
