Can You Put Solar Panels on an Old Roof? What Homeowners Need to Know

If your roof is more than 10 years old, you might be wondering: "Can I still go solar?"It's a smart question — and the answer isn't one-size-fits-all. In this blog, we’ll break down what to consider if you’re thinking about installing solar panels on an older roof, and how to make the best long-term decision for your home and your wallet.

Old roof? No problem. Here’s what to know before going solar—and how to save big by combining upgrades.

Why Your Roof Matters When Going Solar

Your solar panels will last 25–30 years, so you want a roof that can last just as long. Installing panels on a roof that needs replacement in just a few years can lead to extra costs down the road when the panels have to be temporarily removed.

Here’s what matters most:

• Roof Age: If your roof is 15–20+ years old, you may want to replace it first.

• Material Type: Asphalt shingles, metal, tile — some are more solar-friendly than others.

• Structural Integrity: A roof inspection can reveal if the structure can handle the added weight.

• 
  

Can I Still Qualify for Solar If My Roof Is Old?

Yes — but you may need a roof inspection or upgrade first. The good news?At Solano Solar, we work with trusted local roofing partners to bundle your roof replacement and solar into one package, often with $0 down financing and federal tax incentives that help cover both.

Should I Replace My Roof Before or After Going Solar?

Here’s the rule of thumb:

• If your roof is under 10 years old, you're likely good to go.

• If it's over 15 years old, you should strongly consider replacing it first.

• If you’re not sure — schedule a free inspection. We’ll give you honest advice with no pressure.

Bonus: Replacing your roof and installing solar at the same time often qualifies you for the 30% Federal Solar Tax Credit on the whole package — not just the solar panels.
