We are delighted with our new roof. The installation has been done in two stages. First, we had the interior insulated and the finish is UPVC boards which actually give us more light and insulation. Secondly we had the old polycarbonate roof removed to be replaced with boards and extra insulation and finally finished with lightweight tiles. We now have a roof which can be stood on with new fascia boards and guttering. Sound insulation is improved and the room has been turned into all the year round living space with its increased light. Overall much cheaper than alternative companies and the materials and workmanship are first class. Each stage only took one day.
