Legacy
Shane Mehling of Decibel, commenting on the album's nu metal sound, likens the reaction from the metal community to the Electric Dylan controversy and writes that "there's still plenty of raw emotion about what that record did to heavy music." Mehling himself deemed the record "a massive blow to metal purists, some of whom had already been disappointed by Sepultura moving away from thrash on their previous album, Chaos A.D. The smolder of Korn's increasing popularity may have worried some, but Roots was like Nero downtuning while Rome burned." Greg Whalen of Terrorizer, who was a fan of Sepultura, recalled that Roots "was like someone took a fish and slapped me across the face with it. It was the most reprehensible thing. They could write these amazing riffs and technical parts, and they just dumb it down to lowest common denominator status. And it almost physically hurt me."
Speaking to Kerrang! in 2008, Max Cavalera looked back on Roots:
Roots came from a blurry dream I had about going to the rainforest. Wine may have been involved. In the end, when we actually went into the forest to record, it was unbelievable. The whole album was a huge personal journey for me, and as a Brazilian, it felt as an incredible achievement. Everyone was inspired and Igor was at the top of his game. The percussion was crazy and we worked with so many great musicians, in the end coming out with a 15-minutes drum jam that someone likened to a crazy Brazilian Pink Floyd. When we took the album to Roadrunner they loved it except for the title. They thought it would sound like a Bob Marley tribute album. We explained it to them, and thankfully they got it.
As for the Xavantes, both their leader at the time of the band's visit (Cipassé) and Pappiani agree that Roots helped the tribe gain some visibility, to the point that people would actually identify them as Xavantes instead of just calling them "indigenous people". Pappiani noticed an increase in people's interest for information on the tribe and their music.
On March 25, 2021, French heavy metal band Gojira released the single "Amazonia", a song about anti-deforestation of the Amazon and the protection of Brazilian indigenous peoples' rights. Shortly after its release on April 15, frontman Joe Duplantier in an interview with Blabbermouth.net was asked his thoughts about comparing "Amazonia" to Sepultura, to which he said:
I go, "Yup." And it's a compliment, and there is no shame here. And we ripped them off, but we didn't do it on purpose. But we realized it right after. We were, like, "Oh, that sounds like SEPULTURA. Ahhh, whatever." It's a tribute to Sepultura — how about that? It's about Brazil. It's about the Amazon. It's tribal.
Brazilian UFC fighter Alex Pereira uses the song 'Itsári' as his signature walkout music before his fights. Commentators have noted the connection between the song and Pereira's indigenous heritage.
Saby Reyes-Kulkarni stated of Roots in 2016, "we can still only point to a handful of acts that have even nibbled at cross-continental mass appeal by blending metal with music that strikes Western ears as comparably remote and alien", noting the Armenian, Assyrian, and Sumerian cultural influence on Melechesh; as well as the Taiwanese cultural influence on Chthonic. Alien Weaponry have also been compared to Roots-era Sepultura due to their usage of Māori culture in their music, stemming from their own Māori heritage. Drummer Henry de Jong said they were not aware of Sepultura before writing their first song in the Māori language, but Youtube commenters compared them. de Jong found it strange seeing how similar they were despite being years apart and not knowing what Sepultura had done.
Keith Kahn-Harris analyzed the album's influence for its 25th anniversary in 2021. He found it important for expanding the boundaries of metal into other kinds of music in the world, but considered the album's sound to cross the line from raw into half-baked at times, particularly in its integration of Brazilian music. He states "In folk metal today you find a much more seamless melding of metal and its musical others. Korpiklaani and Finntroll are not jam bands, they are effortlessly slick and do not question their entitlement to evoke their mythic ancestors. Orphaned Land and Melechesh are not incorporating Middle Eastern influences into their music, it is their music. Even bands that owe a lot musically to Sepultura, such as Alien Weaponry, sound much more comfortable in their own skin." Kahn-Harris also argued that while Roots was influential on nu-metal, it didn't entirely fit due to its influence from 80s anarcho-punk. He concluded that Roots "doesn't really map out as much new musical territory as was claimed at the time", but was nonetheless still very enjoyable. That same year, the staff of Revolver included the album in their list of the "20 Essential Nu-Metal Albums".
In 2025, Rae Lemeshow-Barooshian of Loudwire included the album in her list of "the top 50 nu-metal albums of all time", ranking it eighteenth. Spin ranked Roots at number 30 in their 2002 list of the "40 Greatest Metal Albums of All Time", with Chuck Klosterman deeming it "death metal as world music as universal horror-flick soundtrack" and praising it for advancing the use of native Brazilian sounds from Chaos A.D., saying Roots mixes "tribal chants, polyrhythms, and norteamericano ringer Jonathan Davis of Korn with political fury and into-the-abyss guitar."
