Young Gun CLAYTON Rathjen

Problem Solving for the Modern-day Commercial Roofing Market

Compiled by Art Aisner

Being underestimated is Bradley Rathjen's competitive advantage. At 23, the estimator and project manager at Madsen Roofing & Waterproofing in Sacramento, Calif., has learned that when clients doubt you because of your age, there's only one response: become undeniable. That mindset helped him secure several million dollars in work during his first year in the office—not by taking shortcuts, but by holding himself to a higher standard than anyone expected. 

While some might view youth as a liability in this industry, Rathjen has turned it into an asset by pairing energy and adaptability with an unwavering commitment to professionalism—earning the respect of owners, manufacturers, and consultants alike, one project at a time.
