Standard Industries, a privately held global industrial company operating in more than 80 countries with more than 20,000 employees, has announced the appointment of John Altmeyer as CEO of GAF, North America’s largest roofing manufacturer. Jim Schnepper, who was appointed GAF president in 2017 and became CEO in 2021, has stepped down after 28 years at GAF and is joining the Standard Advisory Board.
Altmeyer’s new role is effective immediately. He joined GAF in 2021 as executive chairman, commercial roofing. Under his leadership, GAF Commercial sales have more than doubled and significant strategic progress has been made to set the business up for continued growth. Altmeyer previously served for 21 years as president of Carlisle Construction Materials.
“John Altmeyer is a renowned industry leader who will draw upon his deep experience, relationships and track record to drive GAF’s next stage of growth,” said David Millstone, co-CEO of Standard Industries. “Over the past few years, as executive chairman, commercial roofing, John set GAF up to be as successful in commercial as it is in the residential market. We now look forward to working with him as he leads the entire company into the future.”
Schnepper led GAF during a period of tremendous growth and transformation and through the challenges of the COVID-19 pandemic.
“We are grateful to Jim Schnepper for his dedication to GAF over his many years with the company and wish him success in his next chapter,” said David Winter, co-CEO of Standard Industries. “As one of the industry’s most respected executives, John is the right person to step in as CEO of GAF. He will build on the momentum he helped create in GAF’s commercial business and continue to strengthen and expand GAF’s broader leadership in the industry.”
