My wife and I agreed to use DuPont roofing based on the excellence of previous work by their parent company Infinity Design Solutions. Having decided to install solar panels on our roof it was clear we would need a roof replacement prior to the solar panel installation. Jeremy Goldman from DuPont roofing was easy to work with, patient with questions and made several thoughtful suggestions to improve our roof replacement. His work crews arrived on time, were professional and very efficient. We are very pleased with our new roof, replacement skylights and gutters. Two of our adjoining neighbors were so impressed by the work on our home that they had their roofs replaced by DuPont roofing as well. That is high praise for work well done!!
