When you go solar, your roof warranty is voided on the portion of the roof that you install solar.
Don’t worry, you’re still going to be covered under your installer’s workmanship warranty. An installer’s workmanship warranty is generally for 10 years and it covers the areas of the roof they worked on.
If there are any issues with the areas your installer worked on, you’ll be covered bumper to bumper for 10 years. If there are problems with the rest of your roof, your roof warranty will still cover you there.
Some installers will even take on the remainder of your roof warranty if they are confident in both the condition of the roof and their own workmanship.
Either way, you’ll be completely covered.
