Brief Description

A flat roof on a pitched roof would be a layman‘s fair description of the Berlin-style roof. More appropriately it is described as a truncated, asymmetric mansard roof. This type of construction is frequently encountered in large cities and dates back to the beginning of the 19th century, when there was a need for low-cost accommodation. The basic conditions here were as follows: The roof structure of the U-shaped apartment building was made of wood. The visible faces of the pitched roof were shingle-clad and the flat roof was waterproofed with bitumen sheeting. When the leaking roof was due for refurbishment, the apartment owners‘ association chose a liquid-resin waterproofing system with fleece reinforcement throughout to preserve the fabric of the building.
