Who are you sending to my house?

Before your appointment, we’ll send a picture and short bio of your designated roofing or construction expert, so you know who to expect.

We help you make an informed decision.

We walk your roof whenever possible, and take pictures so you can see what’s going on up there. Then, we’ll explain what we recommend and why, so that you can be confident about the work being done to your house.

We respect your home.

During the job, we take every precaution to leave your property in better shape than we found it. Roofing and construction work can be messy – but we clean up as we go, run magnets to pick up stray nails, and use special equipment to keep the debris contained.

Crafting a Legacy: The Mast Family

Value begins with a strong foundation and Kerwin and Corrie have been laying the groundwork for Mast Roofing since the very beginning. It all started in 1997, with a one-man crew and vision to honor God through superior craftsmanship. Growing up on a farm, Kerwin learned the value of hard work and integrity, core values that are woven throughout Mast’s framework. Above all, Kerwin’s desire is for every person that encounters Mast to experience unparalleled excellence, walking away feeling cared for and respected. On any given day, Corrie, our CFO, can be found carefully reviewing statements, while Kerwin crunches numbers, carefully casting the future vision for the business. In the in-between moments of life, they can be found enjoying the outdoors, tending beehives, and spending time with their three children.

What Our Clients Say

We love our team and the
community does too!

“I have used Mast three times and each time I have been more than satisfied. They did a huge project on my complicated old stone house and bank barn. The slate was replaced with metal roofs. They started on time and stayed until finished. I was so satisfied that I then had them tear down and build a large porch on the back of my father’s home. Again, an excellent job from start to finish. Extremely caring and had great advise. They just finished another job at my dad’s house. There was a complicated porch roof and then a flat roof. The job was excellent. Every employee that I met was so nice, knowledgeable and had a great work ethic. I don’t know how Kerwin Mast is able to find such great people. I would like to hire such people to help me around the house and farm. Bottom line is, I was totally satisfied with all three jobs they did. For the second and third job, I didn’t even research for another roofer. I knew I had found the BEST.”

- Connie Unger

“Chris and Jason arrived on time and got to work immediately. They were polite and friendly and very professional. Chris explained everything as the replacement/installation of our 4 skylights progressed. He placed large tarps down both on the enclosed porch and living room, after moving some furniture and the Christmas tree. But everything was cleaned up; furniture replaced when the job was finished. I thought it would be a 2-day job, but the entire process took only six and a half hours! The results are amazing! No more leaks and crystal clear glass! I would recommend Mast Roofing and Construction to anyone! In fact, I just did – this morning!”

- Wendy Futrick

“I reached out to Mast Roofing because of their reputation for quality workmanship AND the owner’s experience / expertise with insurance jobs. Kerwin Mast’s understanding of both construction and the ‘extra work’ that can be associated with the unfamiliar world of insurance claims, helped to expedite what had been a complicated process. But the very satisfying final result was really a collaboration of the Mast Roofing TEAM. Thank you, Mast Roofing team, for a job well done! For anyone in an insurance claim situation: I cannot emphasize enough the value of selecting a preferred contractor, like Mast Roofing, with the right experience and aptitude to deal cooperatively and fairly with both the insurance company and you.”

- Jo Ann & Todd Spidle

Keith was very professional and explained everything thoroughly. I feel very comfortable and secure that Mast Roofing would fix my roof the correct way and I would not be taken for a ride. Excellent first impression.

- Corrie Bates
