After some time he adapted his bowling style, due to injuries and diminshed pace, to encourage augmented swing and movement of the ball.

[6][7] He has also featured for Barbados, Deccan Chargers, Worcestershire along with CPL teams Antigua Hawksbills, St Lucia Zouks and Jamaica Tallawahs in his cricketing career.

[10] He finished with the best bowling figures in the match of 2/29 from three overs, claiming the scalps of Shaun Marsh and Luke Ronchi as the West Indies won by seven wickets.

On 20 August 2008 Roach – along with fellow debutants Leon Johnson and Brendan Nash – made his first appearance for the West Indies in a One Day International.

John Dyson, the West Indies coach, said that Roach was expected to put the more experienced and established bowlers such as Fidel Edwards and Jerome Taylor under pressure for a place in the team.

Varying his length and exploiting the Bangladesh batsmen's weakness against short bowling – even hitting Raqibul Hasan on the elbow with one delivery – Roach proceeded to take career-best figures of 6/48 in the first innings.

[25][26] Shortly before West Indies embarked on a tour of Australia in November to December 2009; senior players such as Chris Gayle and Shivnarine Chanderpaul returned to the squad, but Roach had sufficiently impressed selectors during the dispute that he retained his place.

[27] The West Indies lost the first Test in three days; Adrian Barath's century on debut and Roach's bowling performance were the main positives for the West Indies; in the opinion of former Australia captain Ian Chappell, Roach's bowling was "exceptionally good" but he lacked support from more senior bowlers.

"[30] It was the opinion of Tony Cozier that in the absence of experienced fast bowlers Jerome Taylor and Fidel Edwards, Roach was the leader of the bowling attack in Australia.

However, he was forced to bowl into the wind, which surprised Australian batsmen Shane Watson as it reduced Roach's pace.

He played just two matches for the Chargers in the 2010 season, against Mumbai Indians and Kolkata Knight Riders The West Indies hosted the 2010 ICC World Twenty20 in April and May.

South Africa won the three-match Test series 2–0; Roach played in two matches, taking 6 wickets at an average of 31.

In the lead up, he attempted to develop his use of swing to cope with Sri Lankan pitches traditionally unhelpful to fast bowlers.

He dismissed Pieter Seelaar, Bernard Loots, and Berend Westdijk for his hat-trick and went on to claim 6/27, the fourth-best bowling figures by a West Indies player in ODIs.

[44] Despite not regularly featuring in the Test side, Roach finished the year as the team's leading wicket-taker in ODIs with 30 dismissals from 23 matches at an average of 31.16.

[46] At the time the club was struggling to avoid relegation from the first division of the County Championship, the first-class competition, and in the final game of the season managed to ensure they stayed up.

[47] According to Roach Worcestershire's seam bowler Alan Richardson helped him learn how to bowl in English conditions,[48] and took 14 first-class wickets at an average of 39.28.

[54] On 7 March 2018, Roach took his 100th ODI wicket, having Rohan Mustafa caught behind for eight by Shimron Hetmyer, in an eventual win over the UAE at the Old Hararians Sports Club.

[65] In 2021, Roach signed for Surrey County Cricket Club, joining up with the squad soon after Sri Lanka's tour of the Caribbean.
