Ganser Company will bring your home's original beauty back with timeless products, new innovation, and hands-on displays designed to let your imagination run wild!

There are a lot of great reasons to live in the Madison area, but pleasant, predictable weather isn’t one of them. Snow, hail, ice dams and wind can wreak havoc on your roof. We at the Ganser Company provide service and replacement for all kinds of roofs, including asphalt, metal, slate, tile, rubber, wood shake and thermoplastics. No matter what kind of roof you have on your home, Ganser has the answer.

Our steep-slope residential roofs use only the best made-in-the-USA materials and come in a variety of styles, allowing you to pick the perfect match for your house. Features include an advanced ventilation system to insulate your attic and keep it dry, as well as ice dam barriers that prevent water from backing up in cold weather. We hold a Master Elite certification from GAF, the largest shingle roof manufacturer in the United States and the most trusted name in the roofing business. This means we can offer not just a material warranty but also a 25-year workmanship warranty that few other contractors can match.

Our low-slope single-ply roofs are strong and well-protected against UV damage and heat-aging. Custom-order taper systems will prevent water from accumulating and causing costly long-term damage. If you want, we can also add ribs to improve your home’s appearance. You can further customize your roof to include railings, a deck system and custom-made flashings. Not only are our single-ply roofs made right here in America, they are also certified by Energy Star, helping to keep utility bills low and protect the environment.

During one of the torrential downpours we had late last summer, we noticed that we had a leak in our roof. This spring, I started contacting various contractors for a roof replacement quote. Out of all of the people I had come to view and get quotes, there was only one that bothered to look in the attic and that was Ganser. This is important because I ended up having some black mold started. Ganser used a systematic approach to fixing the problem that involves inspection of ALL of the elements such as proper soffit ventilation, bathroom fan ventilation, and proper attic air flow. They found that for some reason, the entire North side of my roof was blocked of ventilation. There had been continuous soffit vent material placed over plywood with only a few small openings on each side of the roof soffit overhang. Along with this, there had been plywood installed between the rafters up tight to the roof deck blocking all air flow on the North side of my house. I ended up having them do a total roof and soffit replacement on our house along with all new larger gutters. During this process, we found other issues where moisture was a problem that caused some rotting in different areas of the roof overhang. This caused compaction of my attic insulation which had to be removed as a precaution due to the mold. At the same time, they suggested having all of the penetrations for electrical wires and light fixtures foam sealed prior to replacement of insulation which I did have them do as well. They called me several times to verify their start date and answer any questions that I had. They started on time and performed all of the functions within a few days time. I am extremely satisfied with the results. All of their workers are extremely good and they never hesitated to answer questions, show me how they fixed the problems that were identified, and provide me with any information that I needed. Everything was done with a focus on proper repairs. I could not be more pleased. Had I chosen to go with the cheapest repair, I would have ended up with a new roof and continuing problems. The main issue was that the bathroom fans were not properly vented, causing the majority of the moisture problems and with little ventilation there was no way for it to dry out. This would have led to some very major issues in a few short years. Not one other company noticed or informed me of any of these issues and would have gladly replaced my roof and not fixed the problem. Yes, the project ended up costing us more money than anticipated, but now I know that my investment is properly protected for many years to come and I have an excellent warranty to back that up. If we were to sell this house after a few years of retirement as planned, within the next 5-10 years we would have had some very major expenses with another roof replacement. I am so thankful to Marc Ganser and his staff of professionals for their considerable knowledge, understanding, and craftsmanship throughout this project. They have all proven to be trustworthy, timely, honest, thorough, and committed to customer satisfaction. Words cannot explain how thankful I am to them for assistance in protecting a very valuable asset and most importantly the well being of my family by eliminating the mold problem in the early stages and fixing the problem. I now know that I have a very solid roof with ridge vents and soffit ventilation, foam sealed attic penetrations, new insulation, and properly vented bathroom fans. For this, I am truly grateful and can guarantee that Ganser WILL be part of our next home project.

We had 11 windows and 4 doors replaced - what a beautiful difference the new windows and doors have made. We couldn\'t be happier with the quality of the products, the invaluable help, the professionalism of all the people involved in our project (beginning with our first consultation with Marc Ganser, to the workers, to the office personnel). We unreservedly recommend the Ganser Company - you will be glad you chose this business!! We will be using their services again in the near future with more products to improve our home. Thank you Ganser Company!!

We recently had our roof replaced. From the first in-home visit to the free estimate to the actual service, everything was professional and top-notch. Great communication, fast service, high quality and trustworthy. I\'d definitely recommend them...and actually we did...to our neighbors.

We’ve had Ganser do several projects for us since we moved into our home in late 2014 (gutters, soffits, porch overhang, bathroom, and a Trex deck). All projects have turned out wonderfully. The only issue we have had was with the apron on the deck. The vertical face board pulled away from the deck...yuck. Marc Ganser answered our call for help and had contacted Trex for a solution. A Ganser carpenter came out and completed the fix. It looked great for one season and then warped again. Whoops.... When we called again, Marc came back out and problem solved with us. Within a couple of weeks we had a new apron/solution and we have no doubt this fix will be a winner! Ganser is obviously a company that follows through! Thank you Marc. Thank you Ganser Company.
