Key FAQs

  • Do I need solar to install battery storage?

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

  • What can commercial batteries power during an outage?

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

  • Are rebates still available?

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

  • Can I add storage to my existing solar system?

    Absolutely. We retrofit battery systems to older installs and optimize them for your current load and use patterns.

When uptime matters, TAG Roofing & Solar delivers commercial battery solutions that work. Protect your business. Optimize your energy. Let us design a smarter system.

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.
