Standard Industries, a privately held global industrial company operating in more than 80 countries with over 20,000 employees, has announced the appointment of John Altmeyer as chief executive officer of GAF. After 28 successful years at GAF, Jim Schnepper, who was appointed president of GAF in 2017 and became CEO in 2021, has stepped down and is joining the Standard Advisory Board.
“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, Altmeyer 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.”
“We are grateful to 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, Altmeyer 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.”
Schnepper led GAF during a period of tremendous growth and transformation and through the challenges of the COVID-19 pandemic, as part of his nearly three decades with the company.
“It has been an honor working at GAF to help Americans protect what matters most,” said Schnepper. “As I leave the company to focus on my young family, including my one-year-old triplets, and take the time to explore future opportunities, I know I leave GAF in great hands with Standard Industries and Altmeyer’s leadership. I look forward to joining Standard’s advisory board and watching the incredible team at GAF continue to lead the industry.”
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. He previously served for 21 years as president of Carlisle® Construction Materials.
“I am thrilled to lead GAF,” said Altmeyer. “I thank Schnepper for everything he’s done for GAF, and I’m grateful for his guidance during this transition. We will further build on GAF’s best-in-class service, product innovation, and customer relationships across all areas of the business. I came to GAF because I know this team will win, and I am excited to lead them forward.”
