Paul Benson scored but wasted countless other opportunities as Dagenham missed the chance to extend their lead at the top of the Conference table.
The striker had seemingly stolen the points when he lit up an otherwise drab opening spell with a 39th-minute blast.
But, with just 16 minutes left, Michael Brough denied Dagenham a 24th league win with a low drive from 16 yards out.
Benson should have done better with a host of chances, while Darren Jones came close for Rovers late on.
