Clement has acknowledged that he would have taken a point before the game at Ewood Park, but being pegged back had left him "disappointed".
The 46-year-old is quoted by the Reading Chronicle as saying: "Maybe before the game a point here would have been a good result, but on reflection, we come away disappointed that we didn't take all the points.
"You're disappointed when you've gone 2-0 ahead and not come away with all three points. Blackburn are probably satisfied that after going two behind that they got back in it."
Reading sit in 23rd place in the second-tier standings, with the point in the North-West being their first of the campaign.
