Both teams will be able to use 13 players during the game, providing only 11 bat and the match is Zimbabwe's final preparation ahead of two Tests against West Indies in Barbados and Dominica.
Roach, 24, has played 21 Tests, taking 82 wickets while 32-year-old Samuels has played 44 Tests, scoring 2,690 runs and taking 24 wickets.
Samuels scored 260 on his last Test appearance, against Bangladesh in late 2012, a series that Roach missed due to injury.
The only other player in the squad with international experience is wicket-keeper Andre Fletcher, who played 15 One-Day Internationals and 16 Twenty20 Internationals between 2008 and 2011.
The team will be captained by Kyle Hope.
Elsewhere, ahead of the July Test series with Pakistan, Jamaica's Sabina Park is set to step in and host the opening Test after the West Indies Cricket Board (WICB) revealed it had given the Guyana Cricket Board (GCB) a deadline of Friday (7th March) to advise on its ability to host the match.
