Rooty was well-received critically. Allmusic gave it 5 out of 5 stars, calling it "so raw you can't believe they spent over an hour per track, so perfect you're glad they stopped noodling about long before most producers would, and so poppy they should get picked up by commercial radio in America as well as the rest of the world".Entertainment Weekly gave it an A- grade and called the album "where heart and feet meet and lovingly coexist".Billboard said the album "revels in exploiting rhythms that shouldn't work—but definitely do".PopMatters' review was mixed, calling the album "either a brilliantly innovative record, or an unlistenable mess, depending on your point of view".
Pitchfork Media's initial opinion on the album, however, was very negative. While calling band members Felix Buxton and Simon Ratcliffe "two of the weirdest, most innovative and talented house producers on the scene", the website's wrote that "[Basement Jaxx] have taken kitsch too far", noting that the music is "often so tacky that it's impossible to stomach." However, Pitchfork would later name Rooty the 33rd best album of the 2000s.
Q listed Rooty as one of the best 50 albums of 2001.
