She became a member of the Committee on the Affairs of the European Union and a substitute member of the Committee on Internal Affairs of the German Bundestag. Furthermore, she was elected chairperson of the newly established Committee on Human Rights and Humanitarian Aid. On 9 March 2001, Roth was elected Federal chairperson of Alliance 90/The Greens at the party conference in Stuttgart and resigned as a Member of the Bundestag at the end of March 2001 as a result. At the same time, she was spokesperson of the Alliance 90/The Greens on women's affairs. In the 2002 national elections, Roth was elected to the Bundestag as Bavarian lead candidate for Alliance 90/The Greens. Since then, she has been a member of the Bundestag's Committee on Foreign Affairs and the Committee on Cultural and Media Affairs. She is also cultural affairs spokesperson for the Alliance 90/The Greens parliamentary group in the Bundestag and chairperson of the German-Turkish Parliamentary Friendship Group.

Roth became federal chairperson of Alliance 90/The Greens again in October 2004 and was re-elected as such several times, most recently in November 2010. In 2012, she failed to become the number-one woman in the campaign for the 2013 national elections. After this defeat she was unsure to run again for the position of leader of the party's board. Fellow party member Volker Beck started a support campaign in favour of her in social media networks and called it candystorm. The party members subsequently re-elected Roth with 88.5 percent backing. Roth served as deputy chairwoman of the German-Iranian Parliamentary Friendship Group between 2005 and 2009 and held the same office in the German-Turkish Friendship Group between 2005 and 2013.
