"It was a good level of event, attracting maximum entry, so we're pleased with producing such good performances," said Roberts.
"We acknowledge it wasn't a World Cup or Grand Slam but it's a good stepping stone for many players who are looking to move on to the next level and it's important for us to make winning a habit."
The eight-strong GB team, selected by head coach Patrick Roux, produced two gold medals and a bronze while a host of established internationals entered themselves and excelled in Scandinavia.
The in-form Ashley McKenzie (pictured) defeated France's Sylvain Goulet and Spaniard Raul Clemente by ippon before seeing off Israel's Ohad Idels by a waza-ari.
McKenzie, 21, who triumphed at the British Open in May and German European Cup in August, overcame Scot Graham Trinder to seal a final against Sweden's own Olle Sundstroem.
A single waza-ari was the difference as the London talent produced another fine gold medal-winning outing on the European circuit.
Britain's other gold medal winners were Megan Fletcher, Karina Bryant, Jan Gosiewski and Tom Reed.
