While most people his age have been retired for decades, the 95-year-old plumbing contractor has officially been recognized by Guinness World Records as the Oldest Plumber in the World, honoring a career that spans more than 75 years in the plumbing and mechanical trades.
The record was officially verified March 5, 2026 following a detailed review of Lighthart’s birth records, current trade licensure and proof of active employment with The Lighthart Corporation.
Career in the Trades Spans More Than Seven Decades
Born in 1931, Lighthart entered the trades at an early age, working alongside his father before beginning a formal apprenticeship with the Army Corps of Engineers in the 1950s.
Over the decades, he witnessed major changes in the plumbing industry—from evolving materials and tools to advances in installation methods and system technologies.
Despite those changes, his approach to the work has remained consistent.
“Roger never set out to break a record; he just never found a good reason to stop working,” said Rogers wife Jackie, “He enjoys the challenges and problem-solving. He has seen the industry change over the years, the materials, tools and technologies, but at the end of the day, as Roger says, water still runs downhill.”
Still Active in the Field Seven Days a Week
Lighthart remains actively involved in daily operations, continuing to work seven days a week on plumbing and mechanical solutions for commercial and industrial facilities.
When asked about the key to staying active in the trade well into his 90s, his answer is simple.
His secret to longevity? “Never stop moving”.
Longtime Industry Leader and PHCC Member
Throughout his career, Lighthart has also been deeply involved in industry leadership and advocacy.
“We are honored to celebrate Roger’s achievement,” said Sandi Soleta, Executive Director, PHCC Los Angeles. “He isn’t just a record-holder; he’s a mentor to the next generation of tradespeople and a testament to the idea that if you love what you do, you never want to retire. Roger has been a PHCC Los Angeles member for 72 years, serving on the local and state boards, he has also served as Chairman of the California State License Board and held many other positions within the plumbing industry.”
A Fixture in the Plumbing Community
Since the 1950s, Lighthart has remained a constant presence in the plumbing community through both his work and his industry service.
The Lighthart Corporation provides plumbing, general engineering and mechanical services and is proud to include one of the world’s most experienced plumbing professionals on its team.
Even after more than seven decades in the trade, Lighthart continues doing what he has always done—solving problems and keeping systems running.
