About us
brennwald+heilig AG is a long-established sanitary and metal roofing (Spengler) business based at Tobelstrasse 8 in Männedorf in the canton of Zurich. The company has existed for over 100 years and has been firmly rooted in the municipality and the surrounding villages since 1919. Its fields of work include metal roofing work with metal roof coverings, sheet-metal façades, chimney claddings, lightning protection systems and sealing, as well as sanitary installations for new builds and conversions, including repair, maintenance and a 24-hour emergency service. In the field of solar energy, the company implements thermal solar systems and photovoltaic systems as in-roof, on-roof or flat-roof installations. For pitched roofs, sheet-metal shingles and sheet-metal diamond tiles made of copper sheet, coloured aluminium or matte stainless steel are used; flat roofs and terraces are sealed, renovated and redesigned. Customer groups include private builders, architects, engineers, commercial and public clients. Since 2026, the company has been managed by a six-member executive management team; it is a training company and a member of Suissetec.
