This method

Roofing copper is made in ribbons, it is cut into the sheets of the desired size already at the installation site. This allows you to arrange a roof without technological holes. The strips of copper are laid by the method of folding — special equipment are attached to each other by the bending method. This method gives the optimal quality of the seams even in the conditions of a minimum slope of the roof. Since all components are also made of copper, almost all the remains are used during installation, and less than half a percent remains waste.
