When the men arrived, they began throwing asphalt roof debris on the bushes and walkways below the roof. When we asked them why they didn't use a tarp to protect what was below, they said they had forgotten to bring one. We gave them one tarp we had but it was not large enough and debris was still getting all over the place. We complained by phone to Mike, the owner, who called the workers and told them to be more fastidious and clean up, but in the end, they left a sidewalk dark with asphalt debris and dust, as well as the ground around the bushes. My wife had to spend about 3 hours cleaning up the mess. When the owner, Mike, called to check out how things went, we told him what a mess they had made, even though the new roof looked good. Mike came over immediately, inspected the new roof (which he thought was well done), agreed with us that the mess the men made was unacceptable, was very apologetic, and gave us a $250 discount because of the trouble that had been caused. All in all, I believe that Mike has high standards and has taken appropriate action to see that this sort of thing doesn't happen again, but in all honesty, I can't give a good rating because of what happened.
