A master craftsman's business with a signature touch
Blang & Lauterbach is an owner-managed master roofing company based in Mertert. For more than two decades, we have delivered roofing projects throughout Luxembourg – from classic slate roofing to modern flat roofs and energy-efficient renovation.
As a master roofer, Michael Blang focuses on what matters: honest advice, careful workmanship and materials that live up to their name. We plan, coordinate and build your roof from a single source – with no loose ends and one dedicated contact.
