His father John told the Spokesman-Review on Thursday that the group had been attempting a route that had only been completed for the first time just two decades earlier.
They were attempting a route called M16 on the east face of Howse Peak, Roskelley said.
It appears the climbers were caught in a size 3 avalanche, said Chelsey Dawes, a spokeswoman with Parks Canada. Authorities launched an aerial search the next day.
"This is one of those trips where it turned into a nightmare".
After the men were reported missing on Wednesday, park officials used a helicopter to search for them from the air, and "observed signs of multiple avalanches and debris containing climbing equipment", Parks Canada said in a press statement obtained by CNN.

If you want to be a 21st century Columbus, you probably have to be either an astronaut or a mountaineer.
Three famous hikers are feared to have passed on after an avalanche in the Canadian Rocky Mountains.
Lama is renowned as among the very best, if not the best, of the world's "super-light" mountaineers who ascend peaks amazingly quickly, with minimal equipment. His sheer determination took him to the peaks of the most hard mountains in the world, while his passion rubbed off on the entire mountaineering community.
Roskelley climbed Mount Everest in 2003 at age 20.
In the ensuing years, Roskelley would decide to pursue climbing as a career, making a living as a welder until he could afford to train and climb full-time. "It's a very bad accident, terrible", said Messner in an interview with the APA.
"We can't speculate ... every mountain, every valley has its own conditions", he said.
"I think it's really important to say that he was just totally in love with his wife", John Roskelley said. As conditions worsened, he yelled out to his son, "Jess, you've got to move faster, or we're going to die right here". They were part of a North Face-backed team, as the company confirmed.
And then, of course, there was Everest.
On Instagram, he wrote: "We choose to play by the rules of the mountains because they are our calling".
