Technical FAQs 4

Can you replace a roof with solar panels?

Simply put, you can’t replace a roof while it has solar panels on it. So, when a home with roof-mounted solar panels needs a new roof, the solar panels have to come down. Modern solar panels for homes and businesses are often guaranteed to produce energy efficiently for 25 to 30 years. In theory, that’s not a major issue.

How do you replace a solar panel on a roof?

For homeowners who already have solar panels installed but need to replace their roof, the process involves a few additional steps: Contact the solar panel installer: They will need to remove the panels and mounting hardware before roof work can begin. Coordination with the solar installer is crucial to ensure minimal downtime for the solar system.

How much does it cost to replace a roof before solar?

If you have an asphalt roof over 5-10 years old, you'll probably want to replace it before going solar. Replacing your roof and installing solar costs about $30,000. If you need to replace your roof after you install solar panels, expect solar panel removal and reinstallation to cost anywhere from $1,500 to $6,000.

Can you install solar panels and a new roof at the same time?

When you install solar panels and a new roof at the same time, it's very unlikely you'll need to re-roof during your system's lifetime. Solar panels are more durable than most roofing materials and can extend the life of the roof shingles they cover. Replacing your roof and installing solar panels will probably cost about $30,000.
