Our Analysis
Century Roof and Solar is located in Hayward (Alameda County) and has been licensed for 30 years with an active license status. It also carries workers’ compensation coverage and maintains a $25,000 bond. Customer descriptions commonly reference roofing work (replacements and repairs) as well as solar-related services, including solar installation and solar removal/reinstallation connected to roofing projects.
