Solar Panel Team Working


Service you can trust

At Citadel Roofing & Solar, our effort to gain your trust starts with your first call to us, and your initial conversation with a member of our sales team. Did we listen to you? Did we explain your options? Did we deliver a proposal that meets your specific needs, rather than a cookie-cutter offering?

After that, we guide you through the process and answer your questions, no matter how many you have. And we provide an attractive product that complements your home or business and enhances your property value.

Company History

It all started with a high school job that sparked a lifelong passion. In the summer of 1977, Dieter Folk worked part-time at his father’s roofing company and fell in love with roofing: serving customers, providing quality craftsmanship and creating safe, stable employment opportunities within the community.

Dieter founded his own roofing company in 1991 and in 1999, the business installed its first solar energy system.

Dieter remains integrally involved in the business, personally ensuring that you are cared for from start to finish when you choose Citadel for your home improvement, commercial or construction project.
