1. An aerial drone for repairing holes or punctures in a membrane on a roof, the aerial drone comprising:
a drone body configured with a motor and propeller;
at least one camera mounted on the drone body, the camera configured to record a section of the membrane,
an applicator oriented vertically and configured to apply material vertically onto the section of the membrane from a nozzle,
a plurality of legs supporting the applicator and the drone, the plurality of legs configured to support the applicator on sliders attached to each leg such that the applicator is attached to the sliders and is configured to slide in a z-direction along the plurality of legs, each of the plurality of legs having a lowermost point,
wherein
the applicator is controllable wirelessly from a different altitude and/or the ground,
the applicator is slidably mounted on the sliders such that the applicator is configured to slide in the z-direction independent of the drone body such that the nozzle is able to reach to a point approximately even in the z-direction with the lowermost point of each of the plurality of legs,
and
the applicator material contains polyvinyl chloride and/or thermoplastic olefin and/or polyolefin and/or ethylene propylene diene monomer rubber and/or bitumen.
