To cover a wound on a leg using a roller bandage, gauze must first be applied to the injury. The main point of a roller bandage is to secure other dressings for the wound. A roller bandage, as the name suggests, is rolled around the wound and then tied off. The knot should be placed directly over, or as close as possible to the location of the wound.
If the bandage comes in contact with an open wound, then yes it should. If a bandage is securing a sterile dressing that completely covers the wound, then as the sterile field is already intact, simple prophylacsis will do.

To secure a first aid bandage using tape, start by wrapping the bandage around the wound and holding it in place. Then, use medical tape to secure the bandage by wrapping it around the bandage and skin in a crisscross pattern. Make sure the tape is snug but not too tight to allow for proper circulation. This will help keep the bandage in place and protect the wound.
