ABC is the largest wholesale distributor of roofing products and one of the largest distributors of vinyl siding in the U.S., primarily serving small and medium-size contractors supplying residential (55%-60% of total 2002 sales) and commercial markets (19%). Business strengths include broad geographic coverage through more than 255 company-owned distribution centers that are strongly customer service-focused, significant purchasing leverage--American Builders
