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!

Amber is a college senior at Trinity International University in Deerfield, IL. She has a passion for writing and journalism (sports in particular), and lends her talents to our social media team and contributes to our industry and news articles.  Alex is a freshman at Carroll College and also has a passion for writing and screenplays. Always willing to lend a hand, you can often find Alex helping out our team (and dad!) with many diverse tasks.
