Founder & General Manager
Hi, I’m Andrew Johnson. I am the founder and General Manager of Prime Seamless Gutters & Roofing, which I started back in 2006 here in San Antonio, Texas.
I was born in Minnesota, but did most of my growing up in Oregon. One of my very first jobs was installing roofs and gutters back in my late teens and early twenties where I learned the basics of the trade, never knowing how much of a foundation it would later become for my future career.
I started Prime Seamless Gutters & Roofing in 2006 wanting to utilize skills I had from my past experience and hoping to make a better life for my family. I have kept the focus of Prime on customer service, attention to detail, quality, and doing the right thing. I am proud of what we have accomplished as a team here at Prime and the most rewarding part of this venture is having an extended family of employees here that I deeply appreciate and care about.
I am married to Katie and she helps me here at Prime now. I also have four children, three boys and a girl. As I write this, our oldest is about to graduate from college, our second just graduated from high school, our third is going to be a senior in high school, and we also have a 7th grader. They keep us busy, laughing, and spending lots of money on gas and food! They are the greatest joy of my life. Other things I enjoy include attending my Christian church and staying connected with my family in faith, boating, camping, BBQ’s, and spending time with friends and family.
Hi, my name is Katie Johnson. I am co-owner of Prime alongside my husband, Andrew. He started the company in 2006 and in 2020, I left my career in custom home construction to work with him and help manage the business together.
I have lived in San Antonio and the surrounding countryside all of my life. I went to high school at Antonian and Clark and I finished school with a B.B.A. in Small Business Management from UTSA. I’ve worked in new home sales, education software sales, and most recently, I held the position of Vice President of Service & Design with a local custom home builder.
Andrew and I have been married since 2011 and we have 4 children between us–all mostly grown now! We also have Tommy Boy, our Labradoodle. I enjoy spending time with my family and kids, hanging out with our friends, boating, camping, and cooking. We are also members of Community Bible Church here in San Antonio and we really enjoy the community we have there.
I love working at Prime because we are empowered as a small business to take care of our customers the right way, adapt quickly to changes, and we have a work family here that we dearly care about.
My name is Mike Riojas and I’m the Sales Manager at Prime Seamless Gutters & Roofing. I graduated from Texas A&M in 2011 with a Business Management degree. I have been in the roofing industry for 9+ years and have done everything from scheduling to ordering, supervising, payroll, sales, and managing sales teams and crews in San Antonio, Austin, and Corpus Christi. I enjoy working for Prime because of the tight knit family feel. Everyone works together and supports one another to ensure we are all providing the best product and service on the market. In my free time I enjoy doing CrossFit, spending time with my dog Harley, and hanging out with friends and family. I look forward to servicing any and all of your roofing and gutter needs!
Hey folks! My name is Carlos Tamez and I’m the Roofing Production Manager here at Prime seamless Gutters & Roofing. I chose to work at Prime because they take care of every single customer. It doesn’t matter if the job is big or small, we just love what we do and we really take pride in our work. In my personal time, I love to ride around in my old trucks, go fishing, hunting, travel with the family, explore new places, and I really, really love BBQing for family and friends. I’m from a small town down by the Mexico border and my parents brought me here when I was a child. Soon after, I became a US citizen of this amazing and blessed country. I have been working on roofs since 2005 and I soon became one of the most recognized roofers in San Antonio and the surrounding area from the roofing suppliers. I love what I do and I look forward to working with you on your project.
