This however was not a last kick of the game victory but a win based on forward power and some useful touches along the back line.
Reece Stansfield brought up the first from a catch and drive after Lewis Allen had floated a penalty into touch five metres out, Allen also on hand with the extras.
Jordan Lord claimed the second after the pack had driven over from short range, Allen again successful with the conversion.
Elliott Husband pulled a try back for the visitors but following some powerful phase play, swift hands across the line created the opportunity for Ian Blackman to go over in the closing stages of the half allowing Rossendale to go in at the interval 19-5 ahead,
In the second period Billingham began strongly with a try by Mark Hopley converted by Dan Finney putting them within a score.
Billingham came again but with Rossendale determined to maintain their lead and the chance of the 'double', Nick Flynn backing up a quick tap by Lord went in to take the bonus point, Allen's conversion sealing the win.
Rossendale still have two games in hand and although perhaps a long shot could still make fourth especially as they have to take on fourth place Lymm at Beechwood.
