What our customers are saying

We're not afraid of letting you know what our customers are saying about us. We will put out warnings about "Storm-Chasers" that don't stick around when the leaking starts or inferior products that will make the initial price of your roof cheaper but when the rubber meets the road – your pocket book gets hit HARD… We'll let you speak to our customers personally about their experience with us.

Dear Ganser Company,

Jose did a wonderful job supervising, insuring the detail matched what the bid had called for, and working late until things were done to my satisfaction. I used them many times!

Dear Mr. Winterberg,

Thank you to you, your crew, and your staff at the Ganser Company for your help with the recommendations and the replacement of our roof, gutters, soffit, and insulation at Westwood Christian Church. We have had time to put these new items into use and everyone agrees it was the best solution to our situation. I also want to thank you for your patience throughout the education and budgeting process as well as completing the project within our narrow window of time and in a professional manner. If you ever need a good reference for your company please be assured you can count on Westwood Christian Church to do so.

Dick J. – WCC Trustee, Madison

THANK YOU SO MUCH!! Every experience I had with Ganser employees was professional and courteous. This was such a good home improvement project for me – I would recommend the Ganser Company any time I have a chance!

Thanks Again,

George and Juliaanne W., Madison

Creative! Enthusiastic! Quality! Experienced! Trustworthy! All describe Travis and his company! Just need to ''nail'' down one last issue.


Duane and Kathy J., Madison

Everyone we worked with were very courteous and friendly. They answered all questions we had. We have had several people stop and tell us how good the house looks! They love the French doors when people stop in to visit. You all did a wonderful job! Nicely done!!!


Al and Madge K., Middleton

My husband and I have been very pleased with the quality of the roof replacement and the quality of your service. Whenever we had a question or problem, someone at Ganser responded quickly and courteously. Problems were fixed in a timely fashion and to our satisfaction. We would not hesitate to recommend the Ganser Company to others who need help with their roofing. Thanks for a job well done


Ed P., Madison

We were particularly impressed by the sense of a well-managed operation; everyone and everything arrived on time as needed and the job was promptly finished.


Peter and Rose H., Madison

We have been very pleased with every aspect of the job Ganser did for us, and we recommend the company most highly.


Cosmas H., Madison

A great company!


Cheryl M., Madison

I appreciated meeting with the representative to go over the proposal. It provided an opportunity to ask questions with a person face to face. It was a good selling point for me.


Carol & John J.

We were very pleased with everyone involved with the Ganser Company, from the office personnel to the estimator and the actual work crew. They were considerate about protecting our shrubs, deck, and driveway. Marc explained step by step the procedure of replacing the roof. The crew picked up all debris and nails following the job. The roof is beautiful and we’d recommend them to anyone needing roof repair. We already told our neighbor whose roof you’re currently doing. Thanks for a job well done!


Jan W., Madison

Many thanks for saving the pieces of damage for insurance purposes. Sure wish we knew about you before we went with the previous roofer!!!


Miron L., Madison

Written by one of our customers to the contractor that referred him to our company:

Just a quick note to thank you for the reference. While, as I assume you know, they are not the cheapest in the market, everything about them was very professional. I very much appreciate your willingness to help me with such references.


Tom B., Madison

Mark took extra care to match (as closely as possible) the existing trim in my 60 year old home. I appreciate what he did.


Jeffrey and Helen M., Madison

My wife and I want to thank you for the fine work your company did this summer when replacing our damaged roof. What started out as a relatively small project snowballed due to a vendor’s error in the materials delivered to our site. However, Jim did the right thing. Without any hesitation, he arranged for the materials to be replaced and the work completely redone correctly. He also attended to several cosmetic details at the end of the project until we were 100% satisfied. As a result, you now have another loyal customer with a good story to tell. As far as we're concerned, there's only one roofer in the Madison area, and that's Ganser. In addition to Jim who managed the project, the fellows who worked on the job were outstanding. Unfortunately, we don’t remember all of their names, but Chase, Mark, and Martin come to mind. Thank you.


Lela M., Madison

Dear Marc: My thanks to you for your quality professionalism in taking care of our roof. I was impressed with Marc's willingness to show me the problems on the roof and giving an honest assessment; that we didn't need a whole new roof. He was patient and diligent in explaining where some additional shingles needed replacement. Thank you and God's greatest blessing to you.


Don H., Sun Prairie

Dear Marc, I just had to tell you how pleased I am with the roof installation Ganser recently completed on our home.

You took the time necessary to walk around with me pointing out things that the previous roofer did not do correctly, and telling me what Ganser would do to correct that, as well as letting me know how Ganser would do things differently.

Your book, with pictures of other roofing jobs that point out various how’s and what’s, really helped us understand exactly what Ganser was going to do.

The crew leader on our roofing project, was very helpful and informative. He took the extra time to show me the proper way to walk on a roof without creating what he referred to as shingle smear. He pointed out several things he thought should be done, and we took his advice. I was very impressed with his attention to detail.

Your people found a potential problem on our roof the previous roofer overlooked, and as a result, recommended to us and then installed a flat roof membrane on a section of the roof and the side of the house to prevent future ice damage. I’m grateful this problem was identified and the change made to prevent a future problem.

We also had Ganser install the optional gutter guards. Now that fall is here and the leaves are falling, we are glad we went with this option to eliminate the continuous need to clean our gutters. (When you come up with an automatic raking and bagging system we would like to hear about it).

The quote you gave us spelled out in detail what would be done to re-roof our home. It was comforting to have it all spelled out in writing.

A co-worker here at work was in need of a new roof on his house and asked me who did ours. I told him how happy we were with the job your company did for us and that you definitely get what you pay for, and I highly recommended Ganser for him to consider. He did and he had you re-roof his home as well.

Thank you for an excellent job, the crew leader, Joseph, for his attention to detail, and all your employees who worked on our roofing project and survived the summer heat.

A thanks to Marc for an outstanding job. We really appreciate it. We’re telling all our friends and co-workers about the great job you did for us.


John and Deb H., Madison

Great job! House looks 30 years younger. Very high quality work.


Tonia N., Madison

I was so impressed with the crew that worked on my roof! They worked hard, kept the site neat and were very courteous. The gentleman in charge explained the measures they took to avoid the problems with leaking that I’d been plagued with in the past. When I went up on the roof to check it out, the preventative measures they took were obvious. Thank you!


Carol A., Cross Plains

I am very pleased with the personal touch of your company and the thoroughness of your service


George and Ann C., Cottage Grove

All problems were promptly and courteously addressed to our satisfaction. Majority of company workers were ''people persons'' and made you feel like a valued customer. Special kudos to Steve Noble's work on the interior trim.


John D., Madison

Your crew was great – cleaned up every evening – tarped over every evening – kept me informed throughout.


Stanley R., Madison

We left for a vacation two days after the job was finished and noticed on returning some siding was bulging. Your crew fixed it two days later. We have told all of our friends and neighbors how pleased we are with your work.


George U., Madison

The project took about four days longer to complete than I was told, but I am very satisfied with the job. It restored the value of my building.


Susan V., Verona

Very few stray nails and shingle pieces found, very little damage to landscaping. In spite of lots of rain, the estimate of time it would take was exactly correct. Everyone we spoke with treated us like a customer, not a bother. The job seemed important to each of them. The young man that did much of the work took time to explain what work was done and why. It was apparent that quality and care were a priority. Thanks for making a dreaded home maintenance project almost pain-free!


Gail S., Madison

As previously, you are A-1. I thought my husband over did it two years ago when you put on our roof (80 mph winds could be withstood). Well, when that tornado went through Madison a couple of weeks ago, I was glad.


Richard S., Madison

I would like to thank you and your staff for the prompt and excellent service in the siding of my home. I chose Ganser Company to side my home in 2004 due to the fact that I chose your company to re-roof my home in 1986. From our first meeting to the end of the project of siding my home, I felt that I received very personal concern in meeting my needs. I would certainly recommend your company to whoever is in need of roofing and siding.


Richard R., Middleton

Thanks to Marc and the crew. It was a wonderful suprise to come home from Milwaukee and the garage overhang was fixed. Thank you very much.


Kevin & Lori K., Madison

Thank you all for our beautiful roof. We were happy to hire such a long standing, family-owned company and even more pleased with your expedient, professional service and kindness!


Rob and Kim S., Madison

We wanted to tell you how pleased we are with our roof that you installed. From the proposal to the final nail, you and your employees did an excellent job. Marc was very knowledgeable in explaining the process, the different quality of the products, and the pricing. We felt comfortable with the accuracy of his proposal. The crew that did the work was very polite. They answered questions we had while the roof was being installed and cleaned up their work areas along the way.

We are sure happy we chose the highest quality architectural shingle. We have had several neighbors compliment us on the roof and asked who did the work. We don't hesitate to let them know that Ganser Company did the work.

Sometimes home remodeling projects can be a real hassle, but we are sure glad that your company made it very easy. Please feel free to use us as a reference.


Bob & Carla C., Madison

I was especially impressed with the clean-up every night. Great job.


Scott P., Cross Plains

I've already given your names to several friends – your team was terrific!! Roof looks great and team worked very hard! Thank you!


Karen K., Middleton

Water was coming in around windows and doors and through soffits before the new roof. Now all of the water runs to the gutters! We are very happy. Your workers were hard working, neat, and friendly! Thank you!


Pat B., Madison

We have used Ganser Roofing Company since 1962. They have done several jobs for us over a long period of time. Ganser has a high quality professional staff who do excellent work. They care about the customer and every aspect of the service provided. The crew manager was excellent. I will continue to use Ganser Company when we have a need for roofing.
