These were H.D. shingles. I don't think they had done many or any projects with these. However the original crew (Shawn) did a good job. The finishing crew did not do a good job. The rain gutters had a lot of debris in them as well as a lot of nails. It cost us $250 to clean them out. Also there is a piece of tin flapping in the wind that is supposed to be attached to our brick chimney. They've come and looked at it and I've left phone messages but nothing has been done nor have they got back to us.
