The Broncos repeated last season's victory at Castleford by scoring three tries in eight minutes at the start of the second half to overturn a 12-6 half-time deficit. The result lifted them above the Tigers who are now without a win in their last five matches.
"We are a very happy team. The players are happy because they know the effort they put in," said Rea. "They played as a team in a difficult game and found the effort required. It was fantastic. Our commitment to the basics and our workrate was excellent."
He added: "Tommy Lee had 80 minutes in really wet conditions and contested and competed on every play. I thought he was terrific."
Chris Bailey scored two tries, Michael Witt kicked five goals and Craig Gower was also a key contributor as the Broncos bagged a second successive away win following their 38-4 success at Salford earlier this month.
"Craig Gower and Chris Bailey both had great 80 minutes. Our full-back and wingers also really worked hard and kept control of the game," added Rea.
Tigers coach Ian Millward felt Australian scrum-half Gower was the main difference between the teams, and he said: "If Craig Gower had played for us we would have won the game. I thought he was the best player by a mile. He controlled the game and was outstanding.
"We did a really good job on Gower and Michael Witt in the first half but in the second half they absolutely dictated to us."
Millward was left to rue a disappointing second-half showing that saw his side slip to second-bottom in the table.
"We were the best team in the first half and really good value for a 12-6 half-time lead. We conceded only one try and that was from a dropped ball but London were the better side in the second period," he added. "We looked a bit of a rabble in the second half and we lost all our shape defensively."
