CONSULTATION » Decking boards » Roof or balcony
The foundation of a balcony or roof terrace can come in two forms: either as a steel girder structure or as a closed surface, sometimes sealed with a roofing foil or tar sheet. In both cases, you have to keep an eye on the railing height and often only have a small amount of construction height available. At this point we clarify the correct preparatory work for both variants.
As a support for the substructure or pedestal and as protection for roof foil and tar sheeting.
So that the foil and tar sheet are protected and do not react with the terrace pads.
The distance between the supports defines the construction of the substructure.
So that your wooden terrace does not rattle later.
The distance between the supports defines the construction of the substructure.
When building a wooden terrace on an EPDM foil (also called roof foil) or welded tar membranes, you must above all keep an eye on the protection of the respective seal. With EPDM foils, we recommend first laying root fleece over the entire surface. Even if weed growth is not usually a problem on roof terraces and balconies, the fleece fulfills the important function of preventing a chemical reaction between the foil and the terrace pad.
Even if the height compensation is less when laying on the roof and balcony than when laying on a slope or on the ground, the surfaces are usually not 100% flat. Here, too, leveling has to be carried out with several terrace pads or pedestals, which also has to keep an eye on the railing height and only has a limited construction height available.
Steel girders offer the advantage that, as a rule, everything should already be “in the water” here, i.e. no leveling of the surface is necessary. To ensure that steel and wood or steel and aluminum do not cause any noise later on, the supports should be covered with patio pads at certain points or with a rubber granulate roller over their entire length.
On many balconies and roofs, the steel beams were welded at intervals that did not match the desired laying direction of the decking. Only with a relatively narrow grid of 50cm or less can the construction timber run parallel to the steel girders. For larger distances, the construction timbers must run across the beams. If you then want to change the laying direction of the terrace floorboards, counter battens are necessary, but care must be taken to ensure that the railing is not too low later on.
