If you add solar to your roof today and then a few years later wanted to reroof, it’s not that expensive to quickly remove the panels from the roof, re-roof, and put them back on. In most cases, the amount of power that you would have saved by installing solar is greater than the cost to remove and reinstall the panels, so it would actually cost you more to wait.
If you plan on re-roofing this year, we suggest you go ahead and do it at the same time as the solar installation. This way, our installation team can work with your roofer and we can make sure that your roof warranty is preserved. It’s extremely common for roofers and solar installers to work together on projects.
