Century Roof and Solar Inc. takes a systematic approach to roofing.

company logo

Century Roof and Solar specializes in installing roofs with a systems approach, paying special attention to ensure all components of a roof and solar system are designed to work together. As an installer of photovoltaic (PV) solar roof systems, the Hayward-based company’s goal is to permanently reduce or eliminate clients’ electric bills.

Owner Tony Diaz has more than three decades of experience in the roofing industry—he’s factory-certified on many roof and solar systems and is qualified to assemble and build composition, tile, shake, shingle, and PV solar-integrated roof tiles. Mr. Diaz holds the coveted NABCEP certification (North American Board of Certified Energy Practitioners) and is a continued education provider for NABCEP.

In 2007, Century Roof and Solar received an exclusive certification from the Tile Roof Institute to improve national roof tile application. Century is also a Master Elite Certified installer for GAF products and has won the GAF Excellence Award the past 15 years in a row. The company invites each client to “enjoy your solar roof on us,” with zero percent interest financing during the first six months of a new roof and/or PV solar system installation.
