I have observed quality workmanship and constant efforts to meet established construction milestones. Further, I have appreciated the professional respect I have received when discussing various issues during the construction process. I look forward to the successful completion of our next project and would highly recommend Cotterman & Company to others who want to work with an excellent roofing company.

We chose the Sika Sarnafil's Decor Adhered Feltback system for our $13,000,000 Elementary building as a cost-effective roof that would be not only attractive but offer durability and superior insulation properties. We have not been disappointed. The standing seam application is truly elegant. Although the project was over 59,000 square feet, your company was on time, within budget, and provided high quality workmanship. Your customer service has been both curteous and professional. The roof to our new elementary school is beautiful and will last for many years.

The professionalism of your staff during our re-roof project was great. The technicians that staffed the job were very conscious and always kept me informed of the projects status. This helped keep the project on schedule and on budget. I would recommend Cotterman & Company and the Duro-Last roofing product to other facilities.

Cotterman & Company was faced with some difficult challenges in the installation of our Duro-Last roof. They met those challenges in a professional and thorough manner. I would not hesitate to recommend Cotterman as a Roofer.

Over the years, we have learned that when it comes to roofs, it needs to be done right the first time. That’s why we trust the experience of Cotterman & Company.

I would highly recommend Cotterman & Company! From their prompt arrival to the completion of the job, it was just quality through and through. It is obvious they are extremely knowledgeable and experienced -- and that transferred over to the finished job! I can state without reservation, Ohio Ready Mix is a very satisfied customer!

I just wanted to write and let you know how pleased we are with our two new Duro-Last roofs Cotterman installed for us. It is a true relief to not have to worry about water leaks every time there is bad weather. The white color has really made a difference in the indoor temperature. This is especially noticeable at our store that has a low ceiling. The roofs look great and it was a pleasure dealing with Cotterman & Company.

As maintenance director of Circleville City Schools I would highly recommend the expert services of Cotterman Roofing. We have contracted with Cottermans for all of our roofing services. In each of these projects Cotterman’s service department was prompt and professional, using the best quality products. They offer a wide range of services that fill our needs and have been an excellent resource with exceptional attention to detail and customer service. We will continue to use Cotterman & Company in our future roofing projects.

Circleville City Schools

I am very pleased and grateful for the service your company has provided us over the last year. Our roofs were in very poor condition and your repair technicians helped us make it through the winter months. When it came time to replace the roofs, your crew was very helpful and willing to go the extra mile to get the job done. Replacing three roofs in a downtown building is no easy task. They kept me informed and graciously met all of our requests. This is the second roofing project we have worked on together and once again the service you provided was excellent.

Cotterman & Company has worked with New Bremen Schools on numerous roof projects over the years. They have always been upfront and fair in their dealings with us. We believe they have done quality work with quality materials. On occasions when we do need repair work done, they have responded quickly, stood behind their work, and repaired the roof to our satisfaction. I would certainly recommend Cotterman & Company to others having any type of roofing needs.

St. Michael the Archangel Parish has utilized the services of the Cotterman Roofing Co. in Minster, Ohio, for both installation of new roof and replacement roof. Most of this work was to install DuroLast Thermoplastic, but also at places to install asphalt shingles. In dealing with the Cotterman personnel, we have always found them to be professional and willing to meet any challenge that arises. They are good for their guarantee of their work and we have established a good relationship. As pastor of St. Michael the Archangel Parish, I would encourage and recommend those in need of roof construction to contact Cotterman & Company, Inc. I know that people will find this company compatible and resourceful.

The entire process from beginning to end was outstanding! The crew arrived on schedule with the necessary materials making our project finished and completed without a hitch. We were very pleased with their service and the new roof throughout the job. Their focus and attention to top quality, professionalism, and high standards was the difference for us in choosing Cotterman & Company versus another roofing company. Community Storage & Properties is a very satisfied customer!

I want to say "THANK YOU" for a job well done by Cotterman & Company! In my previous experiences, I know how hard it is to find someone to complete a job the way you expect it to be done. Cotterman & Company's professionalism and communication from the start to the finish of our roofing project was excellent. Every item discussed about our project was completed in a timely manner and best of all there were no added cost at the completion. Keep up the good work! I look forward to working with you on any upcoming roofing jobs we have in the future.
