In connection with the coating work, the holes caused by removing the old snow barriers were patched with ElaProof H and Base fabric. In addition, the vertical seams of the long miters were treated in the same way. The ventilation of the roof was improved with vacuum fans hand-made by a sheet metal worker. After the coating work new snow barriers, roof bridges and ladders were installed.
