Locally Owned. Committed to Community.
Owner Erik Dieringer started his roofing career after graduating from Waukesha South High School in 1992. What started as Dieringer Roofing exclusively offering roofing services, eventually adapted to Big Fish Contracting LLC in 2001. Years in the industry and experience in other forms of home remodeling and renovation called for a new business that encompassed the diverse services the Big Fish team was able to offer customers. Now, with over 20 years of experience, particularly in roofing and siding, Big Fish Contracting has proudly built a reputation as an industry leader in exterior renovations in Waukesha and Milwaukee Counties.
Family Owned and Operated
When you hire a contractor, you are putting a great deal of trust in that team – believing they will do the best for you and your home, that they will treat you with respect, and that they will provide honest and quality services. An important part of trusting your contractor is knowing more about them. We believe that our dedication to our family and our involvement in the community are a great place to start. We have all built a life in Lake Country – our homes are here, our children are being raised here, and we work with families all over the area. Go ahead and take some time to get to know us and please contact us if you have any questions or are interested in getting started with a project for your home!
Meet the Dieringer Family
Married for almost three decades, Erik and Lindsay Dieringer have worked together not only to build a trustworthy contracting business, but to create a loving, thoughtful family full of passion and creativity. Their four children Amber, Alex, Hannah, and Lola have all played a part in making Big Fish what it is today and have each worked, in some way or another, on the business. Erik and Lindsay are so proud to watch these incredible humans grow into the careers of their choice and love watching them live out their passion in the same way Big Fish Contracting was born from their own shared vision. We are a family dedicated to improving the industries we’re in, focusing on building trust and building stronger communities. These are the family values that continue to drive the growth and evolution of Big Fish Contracting.
