A homeowner estimates that it will take him 6 days to roof his house. A professional roofer estimates...?

A homeowner estimates that it will take him 6 days to roof his house. A professional roofer estimates that he could roof the house in 2 days. How long will it take if the homeowner helps the roofer?
