Rowledge looked to be in trouble in their Watsons national Village Cup Surrey Group final as Blackheath moved impressively to 143-2, with Rob Parrott (54) and Peter Melhuish (62) both reaching half-centuries.
But 16-year-old Max Martin (2-41) got the two big wickets and the home side collapsed to 187 all out in the 40th over.
Ian Metcalfe (41) and Ricky Yates (26) got Rowledge off to a flier as opening bowler Torsten Wrigley lost his radar. But having reached 79-1, they dipped to 105-4, needing 83 from 17 overs.
Ollie Baker, also 16 years old, made a composed 30 as accurate bowling by Peter and Will Melhuish and Simon Mansell (3-28) kept the result in the balance.
When Ben Wish was out for 23, the visitors required 18 off four overs. Tom Nicholls (20 not out) and Chris Yates (11 not out) picked off the remaining runs in an unbroken partnership and Rowledge, with the considerable help of 34 extras (26 wides), won by three wickets with an over to spare.
