Best Roofing Companies In Bismarck

““Tyler Lemmen is a hard worker with great attention to detail, creative problem solving, and great communication. Highly recommend working with him on any projects!”“

“I had a leak that caused interior damage. I had a couple other companies look at it and they weren’t helpful. Tyler was honest with the conversation to problem solve and through the estimate process. He is very responsive to questions. Work to replace roof was scheduled timely. The workers arrived on time, did a nice job, and cleaned up after the job was done! Definitely would recommend them!“

“After a major summer windstorm in summer of 2025, we called ROOFTOP for estimates/repair for roof damage on house.
1) They answer the phone.
2) Showed up when they said they would.
3) Completed the work when they said they would, at the price on the estimate.
This all seems like pretty basic customer service; unfortunately it's getting harder to find.
ROOFTOP delivered in all aspects of our needed minor repairs, and treated us like we were their No.1 customer with first-class service.
Would recommend these guys without hesitation.
They do more than roofs, too!!“

“I am very impressed with ABC seamless on the installation of our vinyl windows, gutters and siding. They are very professional from start to finish. Thanks to Mark D for showing us all the window features“

“Ryan was great to work with and our roofing project was completed timely with no fuss. All the questions I had were answered quickly and the crew did a nice job. Highly recommend!“

“Gabe did a fabulous job on our siding! He went above and beyond working with our insurance company, which was not easy, and handled everything professionally. The finished work looks great, and we really appreciate his patience and persistence throughout the process. Highly recommend New Tech Construction!!“

“Guys were great. I very much appreciate the fact that they made sure that the gate was closed tightly because of the dog. I didn’t have to worry about her getting out.“

“My newly bought home had no gutters or downspouts. Eddie quickly gave us an estimate and time for installation. He was the cheapest price for installation, I called a dozen places. I was shocked at how quick, sturdy, and cleaned up after the project. Maybe 1 hour, and he was done. Have nothing bad to say. Professional and respectful.“
