We dropped about 15 degrees in the summertime with the work your team performed. I now can report that we are keeping about the same temperature upstairs as the main floor. Also, based on the first few snows we have had, my roof has stayed fully snow covered with no ice dams. I want to thank you and your team for their work. PS. It made me smile when I changed out my smoke detetors to Nest and could see spray foam around the electrical box.
