The forward moved to Exeter in the summer of 2023 and was one of a group of impressive new faces in his first campaign as a new-look Chiefs side surprised many with a sixth-placed finish.
But last season Exeter managed just four league wins and finished second from bottom – their worst-ever top-flight campaign.
However, Roots has been in good form this season as Exeter have surged to second place in the Prem ahead of a weekend trip to rivals Saracens.
“I’m here to play international rugby, that’s my goal, it has been been my goal from the start,” added Roots.
“Lots of people have written me off from the early stages, and I always thought it would be nice to prove them wrong, and that was really nice about playing the first time.
“Now it’s about proving myself right. Now I just want to prove it to myself that it wasn’t just a one-time fluke.
“I really want to be back in that squad and show my worth.”
