I live in a townhouse development and we recently had a discussion regarding the fact that when one installs solar the void the roofers 10 year warranty on the roof. Someone called the roofer and asked whether that would void the rest of roofs of the same strip of houses, and they responded that it would. While I know that solar installers will usually come repair the roof if there are issues because of them (I don't think they officially warranty their work, rather they choose to fix it on their own), does anybody have any idea whether or not they'll fix a neighbors roof (regardless of whether the issue was caused by the solar installation or not)?
