In the current year, a few days after snow disappearance, we resumed operations at the review of our roundhouse roof. We were alarmed by visible dislocation of a few rafters supporting the machine room roof surface. This dislocation caused a leak, which has become a serious wake-up call. The roof of the machine room is under our special supervision because of its interesting, original, wooden structure with large spans, dated to 1942. Wooden beams require absolute protection against moisture.

During the inspection, it turned out that a few rafters, based in the wall of adjacent to the hall workshop building could not stand the pressure of snow sliding down on the steep roof of the workshop. The real reason for this was mouldered old rafter ends, there was no doubt that for decades they were exposed to moisture while beeing in spot difficult to seal.

Due to the urgent need for immediate emergency repairs it was carried out. The roof of the machine room on the two sections was removed, the old rafters were removed and replaced with new ones then the new roof surface with flashings and guttering was placed.

Repair work was very complicated because of the need to carry them out with far-reaching care – in the hall there are valuable, old machine tools. At the work time the equipment most vulnerable to damage or flooding has been secured, but moving scaffolding in the hall occupied by units was still very difficult.

The emergency repair was ended in mid-April. During the repair we newly made about 120 square meters of the machine room roof covering.
