To have gains from the labor costs and to solve the problem of asbestos cement it is possible to overlap a new roofing upon an old one. The new flask Riblok allows to fix a new roofing to the old roof without punching it. This is possible thanks to a self-locking system whichs exploit the existing holes of the old roof and which precludes the dispersion of asbestos fibres in the environment.
