Discover the PREFA roof drainage system: Quality products, produced in Austria and Germany
There are times when we complain that so many drops come pelting down from above. And then we experience weeks and months where we really long for the cooling rain, especially with regard to nature. But no matter what phase we find ourselves in, our home should always be prepared for possible (heavy) precipitation. A functioning roof drainage system is the key to reliable and safe protection during heavy rainfall.

Benefits of PREFA roof drainage
No heavy metal pollution:
PREFA gutters and downpipes are made of aluminium, which means that no harmful heavy metals get into the waste water.
Rustproof:
PREFA gutters and downpipes are made of aluminium and are therefore rustproof. No unsightly rust stains appear on the floor nor even holes in the gutter.
Highly resistant:
PREFA gutters and downpipes (rain pipes) are produced from colour-coated aluminium coils. Thanks to the high-quality surface treatment in a coil-coating process, the paint layer remains malleable and resistant, even under extreme weather conditions.

Robust design:
Do you need a more robust solution, e.g. for your entrance area? PREFA also offers robust downpipe systems, with 1.6 mm thick aluminium, in round (robust downpipe) or square (square pipe) versions.
Attractive:
The P.10 colour coating of the roof drainage system makes it a perfect visual match for the P.10 façade and roof systems, which are also matt. For a more angular look, we recommend our angular versions: Box gutter & square downpipe.

Wide range of colours – now also in matt P.10 finish
The PREFA roof drainage system blends in perfectly with the overall appearance, as it can be perfectly matched to the roof system as well as the PREFA façade. As a result, the roof drainage becomes almost visually invisible, if so desired. Alternatively, the colour power of the roof drainage system can be actively used to set accents and emphasise the architecture of the building. No matter which version you prefer, the PREFA complete aluminium gutter system offers you a wide range of colours.
The P.10 finish is a high-quality and malleable lacquer coating that does not flake off. Since the material, aluminium, does not rust either, there is no need for tiresome repainting or touching up. In addition to the colours anthracite, brown and light grey, the colours dark grey, nut brown, PREFA white and black have also been available in proven P.10 quality since 2021. The roof drainage is part of the PREFA complete system made of aluminium and therefore fits perfectly with the PREFA roof and façade systems, both visually and functionally.
In addition to the extensive design options, you as a resident naturally also benefit from the functional advantages of PREFA aluminium gutter systems: Cracks, holes or leaks are a thing of the past and rain can run off safely and reliably. PREFA partner installers will take care of the correct dimensioning and installation of your aluminium gutter. Correct dimensioning and professional installation prevent moisture from penetrating into the walls and causing fatal consequences such as severe water damage. That is why you can rely on guaranteed PREFA quality: Secure a 40-year guarantee on the aluminium material and the colour for P.10 finshes after your purchase.
The PREFA roof drainage products
Half-round gutter
The PREFA aluminium half-round gutter is the semi-circular classic among gutters and rounds off your (PREFA) roof perfectly. This popular gutter shape is available in 4 dimensions, in 3 or 6 m lengths, and in many standard colours also in P.10 quality. It can be combined with the round rainwater downpipe.
Box gutter
The PREFA box gutter is the square counterpart to the semi-circular gutter. It is also available in 4 dimensions and in lengths at 3 m and 6m. Together with the square downpipe, it creates a modern house design. But the classic round downpipe can be combined with the box gutter as well.
Edge gutter
In contrast to the half-round and box gutter, the PREFA on-roof gutter, is mounted on the roof surface using its own on-roof gutter brackets. It is therefore perfect for roof areas at the property boundary, as it does not protrude beyond the eaves, provided that the minimum slope can be maintained. With the PREFA complete set, you receive the coordinated accessories from a single source.
Downpipe
The proven PREFA downpipe is suitable for all types of houses and reliably drains rainwater from the roof. In addition to the numerous standard colours, it is also available in the robust version with 1.6 mm material thickness. Since no heavy metals are leached out of aluminium, the rainwater can be collected in a rain barrel and used for watering the garden without concern.
The PREFA all-in-one system is perfect for coordinating your roof, façade, and drainage. For this residential building, PREFA sidings in brown and Prefa white were combined and matched to the gutters.
square downpipe
Thanks to the concealed fastening and the angular design, the PREFA square downpipe is particularly popular for use in modern buildings. It consists of 1.6 mm thick extruded profiles and is characterised by its particularly high resistance.
