Roof terrace challenge: drainage and waterproofing for professionals

Waterproofing a roof terrace and doing it safely: This is one of the most challenging areas of the roofing trade - not least because of the numerous rules involved. Gutjahr is an expert in drainage and has developed a range of products to help you execute this critical area.

The biggest challenge here is to drain rainwater sustainably - even during heavy rain or thaw. This is the only way to permanently prevent seepage water from accumulating on the roof surface and causing damage to the substructure - which can be immense, especially in the case of roof terraces. This ensures safe drainage and prevents expensive terrace renovation work on flat roofs.

Roof terrace drainage: Mistakes can be expensive

The crux of waterlogging on the roof terrace or flat roof: the visible water damage is not always close to the leaking area due to the largely functioning waterproofing and drainage. In the worst case, the entire roof often has to be renovated when the damage is repaired. This is not the only reason why it is strongly recommended to hire a professional when waterproofing and draining roof surfaces.

The right strategy: waterproof roof terraces and find suitable drainage solutions - especially at edges and in the area of door connections. High-quality products and proper use can prevent water from seeping into the substrate and damaging the entire roof. This is especially true for barrier-free transitions to the interior.

But even in the case of flooring on roof terraces, waterlogging can lead to unsightly discolouration that can hardly be remedied later. Therefore, it is better to install a professional drainage system for the terrace beforehand instead of having it renovated or replaced later.
