    Free structural diagnosis before any recommendation

    An end-of-life metal roof shows recognisable signs: corrosion, leaks, panel deformation, failing joints. Depending on the load-bearing structure, two options: insulated overroofing or full removal and replacement. Vincent Piront SA carries out a structural diagnosis before any recommendation.
