Only one wrinkle in the flashing near the south scupper was observed. The <br />gravel protection layer is thick and protected the roof well from the sun. The existing insulation <br />consists of 2 layers of 1.5" polystyrene and one layer of 3/4" perlite board with BUR ( built-up <br />roofing). R value is about 12, new code is 30. In my estimation the roof should last another 5- <br />10 years with some flashing repairs when needed. When solar panels are added, the city <br />needs to verify loading capacity and also possibly moving the gas lines off the roof or more <br />grouped near the edge to accommodate greater open area for solar panel installation and <br />access. When the new roof is installed, the second RTU heat/AC unit should be installed for <br />the fire hall with new curbing. The existing gas configuration is stubbed for this unit. It may <br />make sense to move the gas meter to the rear of city hall and eliminate 80% of the roof gas <br />lines. One infrared heater stack needs a cap installed and others that are rusted should be <br />replaced. Paul <br />
