They did a nice job. We had major varmit damage in our roof, so we had our roofer strip the shinges and pull up the plywood. The foam gys vacuumed out all the rafter bays and filled them with low density foam.
I think they could ahve cleaned up a bit better, but overall I am happy with their work and they did a good job of coordinating with my roofer. The insulation has made a big difference in the warmth of the house.
