I have done work for this gentleman before on houses that he's bought and renovated and rent it out now he's asking me to give him an estimation on the roof and I work with the gentleman that does have a license and has general liability insurance for himself so I gave the other guy just an estimated price on doing the roof is that illegal for me to do that. So my question is do I have to be licensed or anything in Michigan to give us someone an estimation on what it would cost to do a roof
