About the Team

Meet the people who will bring Roofstar Arizona’s honor and integrity right to your front door.

Jeff Knudson, Owner

He was a young man when it started.

Jeff Knudson was traveling across country with friends when they signed on to a roofing crew in Houston to earn some cash. Down the road in Denver, he became a roofing mechanic, foreman, salesman, and supervisor. In Phoenix, he ran his own office, estimating contracts for first-line builders. Next it was on to Universal Roofers, where Jeff became a division manager for a $2.5 million Sun City West contract. In his own words, Jeff has “seen the roofing business up and down, inside and outside.”

He’s never lost his Midwestern values.

After more than 35 years, Jeff is still very much committed to honest assessments, fair pricing, and quality workmanship. Roofstar Arizona maintains the spirit of the neighborhood contractor. “I do get real satisfaction providing an honest assessment on what they have – and what really needs to be done.”

Melody Knudson, Sales Coordinator

That sweet voice that greets you on the phone is Melody’s. Coordinator by day (aka Chief Spear Catcher), accomplished actor by night, she is at the core of our great service. With a Bachelors Degree in Inter-Cultural Studies from BIOLA University, she has been an integral part of Roofstar Arizona, Inc. since early 2013 and has grown up in the roofing industry with her father Jeff. Melody’s passion for acting is expressed often in live performance at Brelby Theater, Hale Theater, and numerous other art centers throughout the Valley.

Juan P. Diaz E., General Superintendent

This consummate career professional invests his superior skills in the roofing trade in every crew at Roofstar Arizona, Inc. Juan can point to hundreds (possibly thousands) of valley tile roofs he has personally installed, and since 2006, “Juanito” has helped build our reputation as the best roofer in Arizona. This guy used to be a competitive bull rider and member of the PBR, but has more recently taken a calmer road, crooning Latino songs and raising his four children with his wife Jennifer.

Mike Rine, Sales Manager

Mike Rine is the man who does it all. After graduation from high school in Longmont, Colorado, he enlisted and spent his years as a young adult in the U.S. Army. Mike pursued degrees in Business Management and Organizational Communications. Mike is a former remodeling contractor, and has spent many years in the roofing industry. Mike started his construction career excavating basements and foundations in Colorado, and over the years, has made it all the way up to the roof. Leading with honesty and integrity, he takes seriously our saying, “We’ll tell you the truth about your roof.” Mike loves drinking Rockstar, caring for his family, fishing, and hanging with his 160lb Saint Bernard, Hemi.

James Funk, Field Inspector

The laughter, smiles, and hard work James brings with him every day make everyone’s day better. Often a Team Leader for Habitat for Humanity on his days off, James has loved construction since he was big enough to lift a hammer. James and Jeff have worked on many roofing and construction projects together over the years as part of service trips around the country. Tech savvy and quick to learn, James also helps with our website and social media platforms.
