We look forward to strengthening our commercial presence in the region, building on our relationship with Firestone and Mark as he continues to work as Firestone’s agent representative in Northern California, and learning from CRI’s team of commercial roofing experts.”

RSG operates a strategic distribution network of 56 branches across 22 states, focused exclusively on residential and commercial roofing products and accessories. The CRI acquisition further strengthens RSG’s geographic position and ability to serve its customer base.
