Carroll headed home Joey O'Brien's cross in Sunday's 3-1 defeat at Tottenham to end his 1,062-minute Premier League goal drought.
"It was about time, to be honest," Carroll said. "I'm just grateful to have got off the mark and hopefully there will be more to come this week.
"I think I've put myself about and been involved in our goals in previous matches. "I think I've been doing well so it was about time one went in.
"It was a great ball in by Joey O'Brien and I just had to get up and head it across the keeper. That's what I did and thankfully it went in."
