Definitions

• the invention relates to a metal roof panel for cleaning and keeping clean of building roofs, in particular vegetation or environmental pollution, consisting of a metal that reacts in connection with moisture, the metal roof panel being made of plate-shaped material by punching and a structured reaction surface with raised knobs and openings having.
• Such a device for protecting housing roofs against vegetation, in particular against moss and lichen is known from DE 44 13 119 C2 of the applicant.
• the metal roof panel By producing the metal roof panel from plate-shaped material by means of punching, there is the possibility that the metal roof panel can be adapted in a simple manner to the shape of the roof tiles used in the roof covering.
• the curve below can be formed at the same time as the stamping process, so that an optically appealing design results compared to a simple copper sheet and in particular the reaction surface for the flowing moisture between two rows of roof plates is largely utilized.
• Furthermore, there is a simpler assembly of the metal roof panel since the metal roof panel which matches the outer shape of the roof tile can be inserted in a simple manner between the individual rows of roof tiles.
• the production by punching the individual metal roof panel provides the simple possibility of forming a circumferential bead in relation to an inlaid, smooth copper sheet on the outer edge of each individual roof panel, which delays a rapid drainage of moisture and thus increases the reaction time between moisture and metal roof panel. It can be used in stamping the metal roof panel in the downward half of the metal roof panel (reaction surface) knobs are embossed, so that the flowing moisture must travel as long as possible and at the same time a good distribution of moisture is guaranteed on the roof surface.
• punching and the raised (raised) knobs at their highest points openings in the form of slits can be provided, as a result of which liquid can also react on the underside of the metal roof panel with the metal underside.
• the copper sheets are still attached to protect the roof covering against moss growth that occurs over the years in the visible area of the roof surface so that they come into contact with rainwater and the draining rainwater covers the largest possible area of the roof cover below the copper sheets overflows.
• the rainwater dissolves constituents, in particular ions, from the copper sheets, which counteract vegetation, especially moss and lichen, on the concrete or tiled roof panels.
• the copper sheets are preferably in the form of ridge hoods and arranged along the ridge of the roof so that the moisture flowing off can drain off over the entire roof area.
• simple strip-shaped copper sheets can be attached in the area of the roof saddle.
• strip-shaped copper sheet in the area of the roof saddle is relatively easy to manufacture, in which a copper sheet is unwound from the roll, but then only a small effective area of the copper medium remains between two successive rows of roof panels, so that a corresponding one Effectiveness against vegetal growth on the roof surface, a large number of such rows of copper strips must be inserted. This results in a high cost burden overall.
• such copper strips are difficult to attach, especially when retrofitting existing roofs, since the copper strips have to be inserted and fastened between two rows of roof plates, which means that depending on the length of the copper strip used, a larger number of roof plates must be removed.
• the object of the invention is to further improve a metal roof panel for cleaning and keeping building roofs effective and manageable.
• the inclination of the openings of the knobs against the water drainage direction that is to say towards the roof ridge, enables improved water entry to the underside of the metal roof panel.
• an improved utilization of the underside of the roof panel is made possible, so that the cleaning effect on the building roof increases as a result.
• a relatively large amount of residual moisture remains on the underside of the metal roof panel, as a result of which the metal ion removal is increased.
• the openings of the knobs facing away from a viewer of the roof surface standing on the floor result in a more uniform appearance of the metal roof panel.
• a bead support can be embossed on the top of the metal roof panel, which is designed as a support for the roof tile above.
• the narrow space created in this way also provides ventilation for the brick or concrete roof panels of the building roof.
• Figure 1 is a plan view of a metal roof tile formed in the so-called beaver tail format.
• Fig. 2 is an enlarged cross-sectional view through the in

• Fig. 3 is an enlarged, partial plan view according to

• a metal roof panel is shown in plan view, which is formed by a circumferential bead 1 (see also Fig. 2) in the form of a so-called beaver tail roof panel.
• the metal roof panel is punched out along the circumferential bead area 1 from plate-shaped material, in particular copper sheet, the circumferential bead area 1 being stamped in during the stamping process.
• a plurality (here about 150 per metal roof panel) of raised knobs 3 are embossed or pressed out of the reaction surface 2.
• openings 4 which are arranged asymmetrically, offset from the highest points of the knobs 3 pressed out of the reaction surface 2, in particular in the form of elliptical cutouts, are provided (cf. FIG. 3).
• This structuring of the reaction surface 2 in the form of raised, pressed out knobs 3 on the one hand inhibits the flow of liquid, so that the outflowing moisture (rain water, snow water and the like) has to cover the longest possible path between and along the knobs 3 and on the other hand a uniform distribution the reaction surface 2 is guaranteed.
• the flowing moisture reacts with the metal for as long as possible and thus releases copper ions from the metal roof panel, which prevent growth on the roofs of the building and has a cleaning effect on the roof surface.
• the preferred embodiment of the knobs 3 pushed out toward the top 6 with openings 4 punched out during punching or embossing is shown enlarged.
• the asymmetrically designed opening 4 can even extend up to the top 6, as is indicated by a broken line.
• Fig. 4 the metal roof panel is shown in the inserted position between two rows of roof tiles 8, wherein the roof tiles 8 can also consist of molded concrete panels.
• the arrangement of the structured reaction surface 2 located in the lower half of the metal roof panel, as well as the bead 1 surrounding the outer edge, can be seen.
• the one in the upper half, ie above the reaction field 2 shown in FIG. 1, is also of importance.
• a flat intermediate space 9 is thus formed between the circumferential bead 1 and the bead support 7, which results in improved ventilation of the building roofs.
• the effectiveness can be further increased by pre-oxidation, in particular by briefly immersing the metal roof panel in chemical cleaning agents based on alkalis or acids and ultrasound cleaning, so that the otherwise available activation time is avoided until the metal ion solution becomes effective.
• the pre-oxidation can also be accelerated by flame treatment of the reaction surface 2, as well as by sandblasting, which results in an additional fine profiling and thus enlargement of the reaction surface 2 (also on the underside 5).
• the proposed metal roof panel can be used to clean or keep windows or similar elements on the roof surface clean, e.g. B. also for solar cells arranged on the roof surface.
