Customer Reviews

"The whole process with Theisen Roofing was amazing from start to finish. We initially contracted them to do some siding repairs for us Eric Theisen was very willing to help us out, talked me through the entire process, answered ALL my questions, and communicated with me via e-mail and phone. Fast forward 6 months and we were looking to do our roof next, and the answer was easy, Eric was so great with a small repair and their business had a great reputation in our community, they were the only place I looked. Eric came out, measured, quoted us a great price and again answered all my questions and concerns. They were patient in the Spring while I was waiting for my chimney to get repaired, and when the chimney work was done they were very quick to get out and finish our roofing project. Installation was done in 1 day, and I couldn't be happier with the results. Thank you very much Eric Theisen and Theisen Roofing, your reputation preceded you in this installation! Few things to note, I started talking with Theisen Roofing about our roof installation 7 full months before installation started. I signed a contract almost 5 months before the install happened. Remember, when working with contractors, a lot don't have the ability to do you work right away, plan ahead and don't expect them to drop everything they currently have booked for you."
"Brian with Theisen Roofing came to my parents home to address my fathers concern about a possible leaking roof. Brian was not only honest in ensuring my parents there was no problem with roof, he went further to help my parents identify what the concern was within the home. This is a professional who went above and beyond and had nothing to gain, but good intentions. Thank you for your honesty and help, Brian."
"We have been using Theisen Roofing for the past 30+ years for roofing and gutters. We have always experienced professional and courteous service from the owners and their employees. They just put aluminum cladding on our garage door frames and we couldn’t be happier! They also found a product to discourage birds from building nests that they installed on the second story downspouts."

- "I recommend them 100%. Did the entire house and connecting garage and cleanup in two days."
- "A few years ago Theisen Roofing replaced our roof, gutters, downspouts, siding and facia. We were, and still are very happy with the quality of their materials and workmanship. They are also very professional and always kindly responsive to questions we have. Recently we asked them to clean our gutters with fallen leaves going into winter. They were very willing to help, and they did another excellent job. We would not consider going to another company for work on our home’s exterior. We highly recommend their services!"
- "I heartily commend Theisen Roofing for my roof and partial siding replacement. With the pandemic, and the supply chain delays, it was a full year from estimate to completion, but Eric paid attention to my specific requests and carried them out flawlessly. My old roof was a bit troublesome (two layers) but the crew tackled it with impressive skill and professionalism, and I'm very pleased with the results."
- "We had to have leaf gutters installed because of the maple trees around us. Eric came out gave us an estimate, when the job would be scheduled, and the amount of time the install would take. Everything was installed in a professional way and we are very pleased with the work. Would highly recommend this company."
- "Theisen performed some aluminum work around some windows at my house. Eric provided me with a quote in a timely manner. There was a minor issue with some of the windows and they came back immediately to fix them to my satisfaction.. I would highly recommend this company for any roofing or siding work."
- "Theisen Roofing is consistently responsive, reliable, and does quality work. Greeview Townhouse Assoc., Treasurer"
- "We are absolutely satisfied with the work Theisen provided. They provided a quality product and their employees performed in a well and efficient and reserved manner. Overall we appreciated the professionalism and curiosity this company has displayed to us."
- "Thiessen is top of the line in work quality, service, conscientiousness and local tradition. Theissen's 50 years of excellent reputation in this community is well-deserved."
- "The owner came out to check what was causing a drip sound in the furnace room after raining. He went into the attic to check vent connections and on the roof where he found loose shingles and a broken flap on the dryer vent. We were expecting rain in two days so he had a crew out the next day. No more drip sounds. Service couldn't have been better. They were polite and cleaned up after themselves. Highly recommend them."
- "Amazing business. Lightning fast response to our emergency. Followed up and ensured all was done right. Very trustworthy."
