David Humphreys is an American businessman, the CEO of TAMKO Building Products LLC, one of the nation's largest residential roofing manufacturers, and a prominent philanthropist. His fortune is rooted in the family business, which was founded by his grandfather in 1944, and named after the five states it originally served: Texas, Arkansas, Missouri, Kansas, and Oklahoma.

Humphreys' background is in law and finance: he holds a B.A. from the University of the South, a J.D. law degree from the University of Miami (FL), and an LL.M. (Tax) from New York University (NYU). His career began as a corporate tax attorney in New York and Paris at Davis Polk & Wardwell, specializing in complex cross-border transactions. This rigorous legal and financial training prepared him to take the helm of the multi-billion dollar manufacturing company.

David Humphreys succeeded his late father, who had run the company for 38 years, as CEO of TAMKO in 1994. His leadership has been defined by a commitment to modernizing the roofing industry through industrial efficiency and quality control. He implemented rigorous quality management systems, including the Six Sigma quality control methodology and the Deming model.

His greatest contribution has been transforming TAMKO's operational culture by hiring alumni of military academies with strong quantitative skills to implement a process he calls Autopilot (total process automation). This focus on technical rigor, combined with continuous product innovation (like the Titan XT and StormFighter FLEX shingles), secured TAMKO's position against larger competitors, ensuring the family's multi-billion dollar fortune. He also manages his family investment firm, ELC Capital, and diversified real estate holdings.

David Humphreys is a major philanthropist, focusing his giving on education and advancing personal liberty/free-market principles. He and his wife, Debra, founded the Thomas Jefferson Independent Day School (Pre-K – 12) and endowed a Chair in Criminal Justice Advocacy at the University of Miami Law School.

His structural social impact is tied to TAMKO's role as a stable employer (over 1,000 employees) and a supplier of essential, high-performance building materials. His high-profile support for free-market think tanks (like the Cato Institute) positions him as a significant force in American public policy.

David Humphreys maintains the professional, formal style of a Texas industrialist and corporate tax attorney. His attire is consistently high-quality, favoring tailored business suits. His aesthetic is one of serious, data-driven authority, reflecting his commitment to quantitative management and libertarian philosophy.

His luxury is the immense security and autonomy derived from his multi-billion dollar fortune. His life is dedicated to the long-term stewardship of the TAMKO legacy and his profound engagement with public policy and education reform.
