Key FAQs

  • Is roof-mounted solar safe for flat commercial roofs?

    Technically, yes—but it often results in extra costs. It's more efficient to replace your roof first or bundle both services together.

  • What’s better: ground-mount or roof-mount?

    Yes. The portion of the roofing that supports solar panels may qualify for the 30% federal tax credit.

  • Do I need a new roof to go solar?

    Yes. Commercial solar loans may offer zero-down or low-interest terms.

  • Can my system scale as my business grows?

    Yes. We design systems with future capacity in mind, including add-ons like EV charging and battery storage.

Our home is 32 years old and needed a new roof. Karl was great and easy to work with through the estimation/quote process. The office was easy to work with for payments and scheduling. Anthony and his team were fun to work with while delivering on everything they said they'd do. Anthony kept the project running on schedule, worked around rainy days, and was a great resource for us to ensure our home was safe. The new roof looks excellent, new wood work around the roof turned out great, overall very happy.
