Eoin Ryan was Roscrea's inspiration as his side put paid to Causeway in Rathkeale to book their place in the semi-finals.
Roving between the half-forward and full-forward lines, Ryan tormented the Causeway defence and finished with a tally of 1-7, with only three of the points coming from frees.
Causeway also had a top marksman in corner-forward Paul McGrath, who contributed 1-5, but he lacked the necessary support and the game never came to life with Roscrea in front from an early stage.
They led 1-13 to 0-7 at the interval and with Joe Bergin scoring 1-3, the issue was never in much doubt.
All of the Roscrea forwards got on the scoresheet, while in defence Conor Bergin and Colm Hassett were in commanding form.
Scorers -- Roscrea: E Ryan 1-7 (3f), J Bergin 1-3, D Teehan 0-3, M Collier, J Cleary, D Cleary, J Sampson 0-2 each, J Wall 0-1. Causeway: P McGrath 1-5 (3f), P Boyle, D Collins, 0-2 each.
