Jack
Cottrell

Jack Cottrell is the Owner and CEO of Jack The Roofer (JTR), a residential and commercial roofing company based in Centennial, Colorado serving the greater Denver metropolitan area. With roots in the roofing industry dating back to 1996, Jack brings nearly three decades of hands-on experience spanning every facet of the business — from installation and quality control to sales, production management, and company leadership. Jack’s career trajectory is what sets him apart. He started on the crew, rising from foreman to Quality Control Manager where he personally monitored installations to ensure standardized, flawless execution. He then moved into sales, gaining deep insight into customer needs and communication. This dual perspective — understanding both the technical execution and the customer experience — became the foundation for JTR’s operational philosophy when he founded the company in 2015. Before launching JTR, Jack was recruited to build a residential department for a large commercial roofing company, developing processes and systems from scratch. That experience in systems development became central to JTR’s identity — the company operates on a proprietary methodology called “Jack’s Cutting Edge” system, ensuring consistent results through consistent processes across every project. JTR specializes in asphalt shingle, cedar, slate, and concrete tile roofing systems, as well as commercial steep-slope and multi-family housing projects, gutters, and insurance claims assistance. The company holds an A+ rating with the BBB, is a Home Advisor Top Rated and Elite Service Professional, and maintains a reputation for transparent pricing, thorough education, and quality craftsmanship that has earned Jack a loyal customer base across Colorado’s Front Range. Jack is also active in his community as a Toastmasters International Club President and a long-time Boy Scouts of America volunteer. He is a Portland State University graduate and speaks Swedish.
