I think that they did a spectacular job on the roof, but there are things that I did not like. It was promised to be done in 2 days, but was done in 3 because of a small job that they did somewhere else. Clean up was not much on the grass area, but was clear on concrete. They used a magnet and walked over the grass. Apparently, it did not work because I am about half way done & have found 5 nails. They used a blower to move the old roof pieces deeper into the grass. There were still big pieces close to the concrete pathway. What's weird is that they knew that I had a daughter that would probably play there. I do not know how much they cost, since I'm a renter & it was taken care of by my landlord. If they are cheap, and you want clean up after them, then you may want to hire them.‎
