About Us
From established, family-owned companies to more recent startups, our organization brings exceptional people within the building materials industry together to learn from one another, share best practices, and grow relationships. Ultimately, these members achieve success and the highest level of satisfaction that mutually benefits customers and manufacturers.

Our membership of leading roofing and building material wholesale distributors combined now has over 1100 branch locations across the United States and Canada.
Whether they are serving customers in a small town in Alabama or working with vendors in New Jersey, IDAC members are committed to excellence and value.
“Over the years, our relationships with our vendors have been good, but at one point several years ago, our relationship with a key vendor tanked to the point of no return. I made Doug and Tom DeWalt aware of this, and within the next few days, the President of the company flew into town to meet with us. And sure enough, the issues were resolved, and now, they continue to be a key vendor!”
Our Goals
At IDAC, our primary goals include providing effective education for all employees, sharing best practices designed to improve operations, and successfully supporting suppliers to the building material industry.
Our key principles:
- Education
- Best Practice Sharing
- Networking
“Erie Materials was a founding member of American Wholesale. For the past 40 years, the ownership and strategic managers of Erie have grown and developed through this association. The AWL/IDAC organization has provided a platform to cultivate relationships with fellow members as well as strategic vendor partners. We are a better company as a result.”
