Citadel Roofing & Solar is all about Northern California. Our headquarters remains here alongside several offices. We’ve always been based here. Employees live here. Our customers are here. We’ve focused on serving our own “backyard” because our state is home to environmentally-concerned and economically-savvy homeowners and businesses who benefit from Citadel’s solar, energy storage and roofing solutions.
