SPEC Building Materials Corp

SPEC Building Materials Corporation is a wholesale distributor of building materials, selling roofing products, siding, decking and railings, and windows and doors to contractors for both commercial and residential projects. Its roots are in roofing: the company started by supplying equipment and materials to the roofing industry and has since expanded into a full-line distributor.

Contractors can order through the company's branches, pick materials up at the warehouse, or have them delivered to a job site, and the company also offers estimating help, project guidance and some personal lending solutions for projects. The corporate office is at 2840 Roe Lane in Kansas City, Kansas, and the company reports branches in 12 to 13 states, with a training center in Kansas City.
