Citadel Roofing & Solar

Citadel Roofing & Solar is a leading California-based provider of integrated solar energy systems, battery storage solutions, and roofing services. With over 30 years of experience in roofing and more than 20 years in solar installations, Citadel serves both residential homeowners and commercial clients across California from its headquarters in Vacaville. The company manages all aspects of projects with an in-house team—covering consultation, design/engineering, permitting, installation, inspection/commissioning—and offers long-term warranties on workmanship.
Citadel distinguishes itself by holding more licenses than typical competitors within the state’s solar or roofing sectors. Their offerings include advanced technologies such as smart battery backup systems for energy independence during outages or peak demand periods. They also provide bundled roof-plus-solar packages to streamline upgrades for property owners.
Thousands of homeowners as well as homebuilders trust Citadel for its responsiveness and high-quality service; the company has completed thousands of installations statewide—including new construction projects—and maintains a strong reputation among industry peers. Financing options are available through partnerships with financial institutions to make clean energy accessible to more Californians.
