About CMS

Construction Materials Supply, Inc. (CMS) was started in 1990. Over the last 16 years we have grown into a specialty distributor of roofing materials with a reputation for excellent service and fair pricing.

We specialize in Gerard Steel products and all the accessories used with this type of roofing system. We also carry a full line of Owens-Corning shingles and accessories and a variety of high quality fire treated wood shakes and shingles.

CMS uses state-of-the-art equipment to service all the roofing contractors needs. We have a fleet of lift-bed and conveyor trucks servicing contractors throughout Northern California from the Oregon border to Fresno.

Our primary warehouse and showroom are in Livermore, CA where we inventory nearly all the product lines and colors sold by Gerard Roofing Technologies and Owens Corning.
