Tin roofs as a turnkey service

You will also receive all-inclusive turnkey roofs produced as a turnkey service. We manufacture the roof in our own workshop and install it ready for use. Feel free to contact us and ask for a quote on such a package!


The sheet metal can be used to make high-quality roofs for residential buildings, garages, yard warehouses, boat sheds and industrial halls, for example. They are suitable for all roof buildings. We always manufacture the roofs according to the dimensions you give and the dampers are overlapped or split into the width of the roof during the installation phase. If necessary, our friendly dealers can help you choose the right profile and color, and can also provide installation instructions if you want to install the roof yourself.
