Method of manufacturing an identifiable roofing product including a roofing product and a process plant for carrying out the method

A method of manufacturing an identifiable roofing product comprising the steps of:

• providing a first layer of material, where the first layer of material comprises a felt or a web impregnated with a material comprising tacky bitumen and heating the first layer of material;
• arranging at least one RFID tag adapted to communicate via radio waves onto the first layer of material by blowing the at least one RFID tag onto said first layer of material by means of a pressurized gas, wherein the at least one RFID tag is applied onto said first layer of material while said first layer of material has a temperature of about 125-150° C.;
• and
• after the arranging step, providing a second layer of material after the at least one RFID tag is arranged onto the first layer of material, where the combined first and second layer are configured with sufficient flexibility to be rolled into rolls;
• wherein the at least one RFID tag comprises a plurality of RFID tags applied one at a time;
• and
• wherein the plurality of the at least one RFID tags are applied to said first layer of material in a tab region, close to a butt region, and one by one under a theoretical line being substantially parallel to a longitudinal line of said roofing product.
