How We Will Serve You

We get it. Handling the health of your home can be stressful and finding a company you trust to care for your home can feel like an impossible task.
At Mast Roofing & Construction, we challenge ourselves daily to provide a stress-free experience and exceed the industry’s status quo. We’re on a mission to impact others by serving according to our W.I.S.E. model: We Work hard, with Integrity to Serve others with Excellence. From client, to supplier, and into our local community – our goal is to serve you W.I.S.E.-ly!

We're ready to answer your call

We’re easy to talk to – we promise! Even if you don’t know exactly what your home needs or what that “thingy” is called that you want us to look at – we know the right questions to ask to get you to the next step.

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!

“Mast Roofing did a terrific job! We are so pleased with the quality materials and workmanship. Working well and in a timely manner, the workers were respectful of our property and us. The 14″ Velux sun tunnels added in our dreary interior hallway and kitchen are providing excellent lighting without electricity. This was an investment in the long term equity and maintenance of our home, and money well spent. We can feel protected, secure, and safe. Thank you!”

- Sharon Fisherowski

“The problems of our roof were photographed and reviewed by a real professional of Mast Roofing. Solutions were clearly presented and repairs were made that solved our concerns. We couldn’t be happier having worked with Mast.”

- Richard Applegate

“These guys at Mast Roofing are great craftsmen. They installed 2 ridge vents that were not there before. They replaced 2 VELUX skylights perfectly. Extremely courteous team that works seamlessly together. They also replaced a gutter. No mess ever. The cleanup was exceptional. I am a very satisfied customer and would recommend to anyone.”

- Gerard Dolan

“Mast responded to my roof emergency in less than one day! I had an appointment for the afternoon but Chris called to say he was free and could come early, so he arrived in the morning. He was so professional and knowledgeable about our damaged roof from a fallen tree. He assessed the damage, took excellent pictures before and after, and provided an emergency repair in about 30 minutes. Our roof has a steep pitch and Chris was confident and worked safely despite the sharp angle. I can’t say enough about how relieved I was to have him repair our roof so quickly and in a quality manner. With this service we avoided more costly repairs with rain due in two days, so worth the price. We will definitely hire Mast again to do the full repair once insurance has evaluated the claim. Thank you Chris and Mast!”

- Janice Johnson
