I can’t think of anything that wasn’t done efficiently, timely and neatly. One of the workers took my garbage out of my hand and put in the can for me, nice. I am no roofing expert, but all the wood is completely covered along the gutters and sides, shingles are exactly spaced. In addition, we really like the pattern/colors of the shingles. They coordinate nicely with the siding color and gutter colors.
