Jeff Knudson, Owner

Jeff Knudson


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.”

Kevin Murdock

Office Manager

Kevin has been the Office Manager of Roofstar Arizona since 2008 and has been thrilled to watch the company change and grow over the years. The “office” he originally worked in was just 80 square feet (a little bigger than a broom closet) and we’re now in an office building that is about 5,000 square feet! He loves being a part of the Roofstar team and is especially thankful to be working alongside his son, Adam and daughter, Brittany! In his free time, Kevin enjoys baking (his specialties are muffins and cinnamon rolls!), spending time with his black lab, Nellie and bowling. Since 2008, he has been actively serving at his church, The Door Tempe in the areas of prayer and music. Fun fact: Kevin can whistle without moving his lips… Also, make sure to ask us about “National We Love Kevin Day!”


Mathew Arellano

Field Superintendent

I have always had a love for construction, but I wasn’t sure what type of construction I wanted to get into. My stepfather Santiago Carrillo, who was a crew foreman for Roofstar introduced me a young 19-year-old to the company in 2015 and I began working as a crew helper. It was a brutal summer day in August where my love for roofing began. Jeff Knudson who I refer to as ‘Papi Jeff’ began mentoring me and passing on all his knowledge of roofing to me. Jeff has helped me advance in my career and truly made me feel like family. I have met many wonderful people through the years and have seen the company grow in many ways. This company has helped me grow in my personal life to my career life as well. I’m truly blessed to have started working for an honest and family-oriented person like Jeff. We really are a family here at Roofstar Arizona, Inc.

Chris, Project Manager


Project Manager

I was happily adopted into the Roofstar family back in 2017. I grew up with older parents and a father who was a preacher. Their senior age resulted in me becoming an “old soul” with a large variety of interests. Learning how to bridge the gap between the younger and older generations is something I still enjoy to this day. In my free time you can probably find me having a completely random conversation with someone I just met. I find it fun and fascinating to ask about other people’s life stories. In short, I’m an inquisitive guy who likes to listen and learn. After working for a number of years in the corporate sector (banking, insurance, and even watch making) I was happy to find myself making a complete switch into contracting. As a child I originally wanted to be an architect, and now I have the privilege of working in a field that lets me use my strengths to help others. I love the way Roofstar is centered around honesty and integrity. It’s been refreshing working for a company that aligns with my own personal morals where I can simply tell the truth.

Alberto, Project Manager


Project Manager

I was introduced to the roofing industry about a year ago by my good friend Matt and have not looked back since. On my first day at Roofstar, I felt welcomed with open arms and accepted by the Roofstar family. I recently relocated to the little town of Florence with my girlfriend of 3 years, we currently do not have any children, but we are plant parents. On my spare time I enjoy early morning workouts, evening walks with my girlfriend and spending quality time with my niece and nephews. I am excited to keep learning and seeing where my roofing career takes me, I know I am in good hands at Roofstar. I hope you give me the opportunity to tell you the truth about your roof

Mary Knudson

Project Estimator

Mary is Jeff Knudson’s youngest daughter and has been working for Roofstar Arizona since 2017. She decided to join the family business after graduating from the University of Arizona and falling in love with the roofing industry. Mary has done everything from inspecting to bookkeeping for us, but currently is one of our estimators. When she’s not estimating at work, you can find her bird watching, roller skating, cross stitching, or out on an adventure with her partner Corrin and their dog.
