Pitched roofs The traditional roof shapes protect the building permanently from all weather influences. Materials such as clay or concrete tiles, fiber cement, natural slate or metal require not only traditional craftsmanship but also technical knowledge in their application. We would be happy to advise you on this and offer you a solution tailored to your property. Flat roofs The flat roof is particularly popular in modern architecture. Its advantages are better use of space, accessibility (as a terrace or garden) and its storm resistance. With competent advice and good craftsmanship, it fulfills its task perfectly for decades, contrary to many opinions. By greening flat roofs, ecologically valuable open spaces can be reclaimed. Services: For your safety, we recommend our periodic inspection service. This includes: Visual inspection of the roof for damage or loose parts Replacing defective roof material, etc. Checking and cleaning sheet metal connections We would be happy to advise you personally. We look forward to your inquiry.
