Why does a contractor want to know if I plan to live in the home?

[Cynthia Hartley]

Hi everyone,

I purchased a new house as a primary home, although I currently have a primary home that I plan to rent once the new house has been renovated. I called a roofer to give me an estimate to replace the roof of the new house, and he asked twice if it I was going to be living in it. Why would a contractor want to know if I am going to live in the house or not?
