Found some cool info when searching for era-adjusted save%. Some dude on hfboards did it for goalies. Here is the top 10, career:
Player Min SA Saves Sv%
Ken Dryden* 24,105 11,301 10,559
93.4%
Dominik Hasek* 44,465 22,090 20,434
92.5%
Tony Esposito* 54,387 27,782 25,613

Patrick Roy* 62,369 30,475 28,036

91.6%
Tim Thomas 24,448 13,037 11,932
91.5%
Martin Brodeur is actually way down the list. At like rank 35, with 91.0% adjusted career save%.
Patrick Roy jumps up A LOT because the league average sv% in the late 80s was like 88%, and his at the time was about 90% on average. Shows the importance of era-adjusting this stat.
Also interesting, the same poster did adjusted sv% for playoff performances. This added some really interesting perspective on Roy:
Patrick Roy is tied for the second highest career save percentage out of any goalie who faced at least 1,000 shots (Roy faced more shots than the other top five goalies combined). He's also faced 33% more shots than the next closest goalie (Brodeur). No goalie during the past thirty years has surpassed (or even approached) Roy's combination of an extremely high level of performance, and longevity.
...
As I said in the previous post, there is little doubt that Roy is the greatest playoff goalie of the past three decades. He has three of the top seven performances, and five of the top thirty-three. He performed at an exceptionally high level on five different occasions where his team made the Stanley Cup finals, and he was a major reason why they were victorious four times.
