Roy began his broadcasting career on BBC Radio Norfolk in the early 1980s
The commentary position at Carrow Road in now officially known as the Roy Waller Commentary Box.
A plaque was unveiled by Roy's wife Silvie and Norwich City FC chairman Alan Bowkett just before the Canaries' game against Barnsley in September.
"Roy's voice was so much a part of following the Canaries for several generations of fans", said BBC Norfolk editor David Clayton.
Roy commentated on the Canaries for BBC Radio Norfolk for more than 20 years.
He passed away in July 2010 at the Norfolk and Norwich University Hospital, where he was being treated for a liver illness.
"He was that most important thing in BBC local radio - a fan with a microphone sharing the ups and downs of our team," said David.
During his career Roy's dulcet tones brought listeners news of the Canaries' joyous promotion to the Premier League in 2004, as well as the despair of relegation a year later.
"I can think of no better tribute the football club can make than to allow the naming of the commentary box in Roy's honour.
"His name will, quite rightly, live on right above the tunnel at Carrow Road from where he described so many wonderful football moments," he added.
