GAF announced the appointment of John Barkhouse to the newly created position of President, reporting to CEO, John Altmeyer.

Barkhouse, who starts on October 15th, brings over 25 years of manufacturing and operational leadership experience in the industrial, energy, and services sectors to GAF. As President, he will oversee Operations (manufacturing, supply chain, logistics) and R&D for GAF’s Residential and Commercial divisions. Reporting directly to Altmeyer, Barkhouse will work closely with him and the GAF team to build upon the company’s recent success and accelerate GAF’s future growth.

This appointment follows a period of sustained growth at GAF. Over the past five years, GAF has dramatically grown its Residential and Commercial businesses, released innovative new products and increased production capacity across all major product lines. 

“We are excited to welcome John Barkhouse to GAF,” said John Altmeyer, CEO of GAF. “He brings both a fresh perspective and an expertise in growing and operating industrial manufacturing businesses. I look forward to working closely with him as we grow GAF’s position as the best company in the industry.”
