Zimmerman's Roofing

Zimmerman's Roofing is a family-owned exterior contracting firm founded in 1996 and based in New Holland, in the heart of Lancaster County. For three decades, the company has built its reputation on residential roofing work across Lancaster, York, Berks, Lebanon, and Chester counties. Their expansion into solar panel installation was a strategic move that leverages their deep expertise in roof systems, an advantage that matters more than many homeowners realize when it comes to mounting photovoltaic arrays on existing structures.

The company's solar division operates in partnership with Iddings Electric Inc., a sister company that handles the electrical engineering and wiring components of each solar project. This collaborative model means that Zimmerman's handles the roof-side work they know best, including structural assessment, weatherproofing, flashing integration, and mounting, while Iddings manages inverter installation, panel connections, and grid tie-in. The arrangement has earned the team a CertainTeed Master Solar Installer certification, one of the more rigorous manufacturer credentials available in the residential solar space.

For Pennsylvania homeowners, working with a roofing company on solar installation carries a practical benefit that dedicated solar firms sometimes overlook: roof condition assessment. A 20-year-old roof that needs replacement within the next five years is a poor candidate for a solar array, and a roofing contractor is better positioned to make that call honestly than an installer whose revenue depends on selling panels. Zimmerman's ability to evaluate, repair, or replace the roof before or during the solar installation removes a common pain point from the process.

Their 4.9-star Google rating from 556 reviews reflects consistently strong performance across both their roofing and solar lines of business. The company serves a loyal base of Lancaster County homeowners who value the accountability that comes with a locally owned, family-operated firm that has been in the same community for 30 years. While they do not hold NABCEP certification, the CertainTeed Master Solar Installer credential and the electrical expertise provided through Iddings Electric ensure their solar work meets a high technical standard.

With a composite score of 73.8 out of 100, Zimmerman's Roofing earns the third-ranked position among solar providers in Pennsylvania for 2026.
