I have about 10 years of roofing experience and so I wanted to look into being a roofing sub-contractor but when I phoned a roofing company to ask them about it they asked me stuff like what are the roofing codes and how much would I expect to get per bundle and whatnot.

Not hard questions I imagine for someone that's sub-contracted here before but my experience in roofing was only as a grunt. I do believe that I can roof on my own but I just don't know the lingoes and so selling myself as a sub-contractor isn't easy.

So Any information I could get as to all that I would need to become a roofing sub-contractor would be appreciated.
