This old flat roof above a shop in Pinner was leaking for some time. As it’s a walkway to the flat above, the new roof had to have tiles over the top. This roof was well constructed so we were able to use normal concrete tiles rather than promenade tiles. The roof walls were insulated using Kingspan insulation to a depth of 100mm, then a new decking over the top with the Kemperol V210 System.
The difficult details on this job were the flashings to the door step and getting the drain details correct
