Eight PREFA standard colours and an extensive range of accessories ensure that your roof looks fantastic and remains incredibly durable. The PREFA long-term roof, at the core of a perfectly coordinated complete roof range, is the result of ongoing research work and the hardest of practical tests by the leading Austrian aluminium roof specialists, PREFA. Alloys compliant with EN 1396 are used as the base material for PREFA aluminium products. The coating for roof tiles, shingles, roof rhomboid panels, roof gutters, pipes and sheets is applied in the coil coating process and is subject to the strict requirements of the ECCA (European Coil Coating Association) in Brussels. 40-year guarantee on the aluminium base material for PREFA roof tiles, PREFA shingles and PREFA roof rhomboid panels against breakage, rust and freezing when exposed to natural environmental stress and subject to expert installation by tinsmith engineers!
