Roof system 01 : R.16 roof tile

Gables, roof hatches and curves — whether new builds or renovations, an aluminium roof adapts to virtually every roof shape. PREFA’s different products ensure a technically perfect, virtually maintenance- free roof covering.

Original accessories 02 : snow guard, solar panel supporting system,...

The individual components of PREFA’s accessories work together perfectly, guaranteeing high fitting accuracy. Manufactured from a single source, they are delivered together with all the parts required for assembly. This ensures safety and the desired durability of a PREFA complete system.

Roof drainage 03 : box gutter & square downpipe

The drainage systems that have been tried and tested for years are truly outstanding with their sophisticated and detailed technical solutions. They come in many standard colours and are also available in bespoke shades, on request.

Façade systems 04 : Sidings

Aluminium façades are durable and rust-free, and are easy to clean when slightly soiled. The different systems offer flexible design possibilities and the right solution for every building.

Flood protection solutions 05 : flood protection system

Together with our affiliated company, Neuman Aluminium Strangpresswerk, PREFA has developed a demountable flood protection system made of aluminium. This flexible solution allows buildings and properties to be efficiently protected against damage caused by floods.

The reliable partner for…: Always a solution

PREFA products are colour and material resistant and therefore the best choice forroof and facades applications The building material aluminium is ideal for renovations because an aluminium roof does not break and weighs only a fraction of a conventional roof. Furthermore, the PREFA all-in-one system enables optimum interaction between roof, gutter, façade, and solar at top quality. After all, only the best is good enough when it comes to protecting your home. Read more about the benefits!

The advantage of PREFA is that you get a 40-year guarantee on the material and the colour. I laid the R.16 roof tile for the first time here. I followed PREFA's instructions, kept to the vertical lacing and worked according to it, and it actually worked great.

The client was probably also convinced by the durability and sustainability of the aluminium. It protects the house against extreme weather conditions – even in the Rhône Valley it can storm and snow. It also meets the requirements of processing. The organic concept required a flexible material that could follow the flow and form.

Every individual roof and façade product is firmly attached to minimize the risk of storm damage.: 01 Storm-proof

With the unique, concealed fastenings and the special laying technique with offset joints, your PREFA aluminium roof and PREFA façade are able to withstand even high wind speeds. The number of fasteners can be increased depending on the wind load, and the type of fastening (nailed or screwed) can be adapted accordingly.

PREFA roofs and façades are completely weatherproof and guaranteed rust-proof.: 02 Rust-proof

Aluminium forms a protective layer which constantly self-regenerates to protect itself from damage. In addition, on most PREFA roofs and façades, the material is given a high-quality coil-coating finish.

Light in weight yet high in quality: 03 Lightweight

At just 2.6 kg/m², a PREFA roof weighs only a fraction of a conventional roof (approx. 35–55 kg/m²). Therefore, the weight on the roof structure of a typical detached house is reduced by up to ten tonnes! The light weight of aluminium also has a positive influence on transport and construction site times.

PREFA aluminium roofs and façades withstand even the worst weather conditions.: 04 Break-proof

Not even heavy snow loads, extreme temperature fluctuations or bad weather conditions pose a problem for PREFA aluminium roofs and façades. Aluminium’s particularly good properties and resistance are the reason for this.

A unique design for your building!: 05 attractive

PREFA offers infinite design possibilities. Choose from a variety of shapes, formats, colours, installation patterns and surfaces. In the complete system, each product, including accessories, can be perfectly colour-coordinated. Even bespoke colours are available on request in the required quantities.

With PREFA, the colour of your choice remains just the way it is.: 06 Colour-resistant

Thanks to a special coating layer, PREFA product surfaces are highly resistant to temperature and weathering. The reason for this is the coil-coating system which is applied in up to 20 processing steps.

The lightweight material means that there is no need to build an expensive substructure.: 07 Great for renovations

In the case of roof renovations, due to structural engineering reasons, old roof structures often have to be prepared so that they can cope with the extremely heavy load that they are subjected to by modern roof tiles. However, with the much lighter PREFA aluminium roof, there’s no need to make any additional reinforcements.

Roof, façade and many more well-coordinated products: 08 Complete system

Not only is PREFA the strong roof specialist, it also produces high-quality products for façades, roof drainage systems, flood protection and solar panel substructures—tested and coordinated system components for the outer building shell—exclusively installed by trained specialist companies.

Aluminium is fully recyclable.: 09 environmentally-friendly

Aluminium can be recycled as often as necessary without loss of quality. And what’s the best thing about that? The manufacture of secondary aluminium requires 95% less energy than that required to obtain primary aluminium. Aluminium’s light weight (less transport and construction site times) and durability (does not break, rust or freeze) also ensure its sustainability

40-year guarantee on colours and materials: 10 40-year guarantee

PREFA provides a 40-year colour and material guarantee on PREFA roofs and façades. This provides you with optimum protection against breakage, corrosion (rust), frost damage, chips and blistering.
