Q: My peaked roof was recently redone with 30-year shingles and I also had my flat roof foamed. Now I’d like to put solar panels on the roof, but I’m worried about what effect that will have on the warranty for my roofing job. Will my warranty be any good anymore?

A: This change can definitely affect your warranty. You need to have the solar company contact the roofing company in advance to demonstrate how and where the solar installation will be done. Generally, only the warranty on the area covered by panels would be affected. The rest of the roof should still be under warranty.
