About Castagra 

“Amazing company! They are the future of coatings.” — Mike W.


Almost three decades ago,

a growing awareness was swirling around the industrial and commercial products industries: many of the ingredients going into the products they produced were, quite simply, too toxic. The products were incredibly toxic to make, and just as toxic to use.

Also during this time, a small handful of innovators and business experts were studying this problem. They couldn’t believe it was truly necessary to cause potential health issues and to harm the environment in order to produce a high-quality, high-performing product.

Enter Peter Roosen , an engineer, inventor, and construction technology specialist who spent months conducting experiments to disprove that theory — and in the process created Ecodur , Castagra’s revolutionary, incredibly durable, 100% sustainable roof coating.

Making the world a better place

Being “green” was something that Peter took very much to heart. The creation of Ecodur, a VOC- and BPA-free product made from naturally occurring gypsum and renewable castor oil, sparked in all of us both a mission as well as a dream. We saw in Peter’s incredible invention a once-in-a-lifetime opportunity to produce a top-performing commercial product that would improve the lives of others — while also protecting them, and the planet, at the same time.

With mission and dream firmly in tow, we brought the product to the Canadian TV show Dragons’ Den, where entrepreneurs compete by pitching business and investment ideas for a chance to secure business financing and partnerships. And won.

Ecodur took home the top prize on the “Greenvention” episode — and Castagra was born.


Practicing what we preach

From day one, everything we’ve done at Castagra has stemmed from our drive to make the world a cleaner, healthier place for all of us. We truly care about keeping you and your family safe, and we’re committed to helping to protect the environment while never sacrificing performance.

The proof’s even in our name! We combined castor oil and agriculture to bring Castagra to life. The pioneering of Ecodur Roof Coating has allowed us to fulfill our dreams of building one of the leading green roof coating companies. Did you know that in the last 40 years, over 100,000 new chemical compounds entered the consumer market? That’s truly shocking, and it’s fueled our dedication to produce roofing products that are just as safe to create as they are to use.

Whether you’re a roofing contractor or a building owner/manager or a building occupant, you can rest assured that Castagra is the right choice!

Supporting the industry

We care about the roofing industry — and roofers! — just as much as we care about the health of our planet. That’s why at Castagra, we’re always striving to be a valuable resource to you as well as to help move the industry forward.

One way we do this is through the Castagra Roofing Scholarship Program, for those pursuing a post-secondary education in roofing (or a similar field in the building industry) who are also passionate about innovation and/or sustainability.

We also produce a LinkedIn Live series called Roofer Reflections, hosted by our own Tatsuya (Tats) Nakagawa — where he interviews roofers who share their insights on the industry. Tats himself is incredibly passionate about innovation, and every conversation is an opportunity for yet another amazing idea that could revolutionize the industry!
