I purchased new home from this builder 6 years ago. House shingles started falling apart/breaking down in four years. I called builder office. They gave me a phone number of the company who installed shingles. I contacted them and they asked me to send pictures of roof from all angles and 2 strips of shingles so that they can evaluate what type of work they might have to do (In my opinion, this way one way of saying “NO”, as I had to hire someone to meet their requirement). Instead of hiring someone to take pictures of roof from all angles and remove 2 strips, I got the shingles fixed by myself and 15/20 year warrant was not honored.
