Welcome

Capstone Materials Group is a Manufacturer's Representative specializing in commercial and industrial roofing products in the Chicagoland, Northern Illinois and Southern Wisconsin areas. With over 30 years of experience on our team, we are the liaison between our customers and the manufacturers we represent. 

  

As a trusted commercial roofing manufacturer’s representative, we bring more than just projects – we bring solutions. By combining a consultative approach with deep technical expertise, we partner with contractors, architects, consultants, and building owners to deliver high-performing roofing systems tailored to each project’s unique challenges. 


Our value lies in understanding the full project lifecycle-from specification to installation and beyond-providing expert guidance, responsive support, and hands-on training. We help clients navigate evolving code requirements, system compatibility, and performance expectations to ensure long-term success and peace of mind.
