I had three installed 5 years ago, love them and Solar Guys were great to deal with. A phone call to the warranty department would answer you warranty question but based on experiences here the warranties on the shingles are worthless (there are threads to read). I can't imagine any structural issues would be an issue, look at all the solar panels around and expanded lanai's that change roof lines. Then there are the skylights, weather stations and tv antennas (lot of them showing up) so holes in the roof is not unusual but as I suggested, call the warranty department to get your answer.
