The visitors only held the lead for seven minutes as Derby levelled with a goal that will give Leeds keeper Bailey Peacock-Farrell nightmares. Tom Lawrence's direct running was too much for Luke Ayling, the right-back bringing down the Welsh global outside the corner of the penalty area.
Craig Bryson has urged Derby County to "dust themselves off and stick together" following a 4-1 defeat to Leeds United on Saturday evening at Pride Park Stadium.
Alongside Aston Villa and Swansea City, Leeds are one of three sides with a 100 percent start and trail only table-topping Middlesbrough - who have played one more game - after they beat Birmingham City 1-0.
Only a desperate block in the area from a Luke Ayling shot then denied Leeds a third and the superb Saiz then produced another energetic run from midfield before firing straight at Scott Carson.
But there was nothing that Carson could do about a superb second goal for Roofe on the hour mark as the striker produced a sensational touch to turn Fikayo Tomori to work space for a deadly finish that was smashed into the net.
Leeds struck again with devastating speed. Pablo Hernandez, Samu Saiz and Ezgjan Alioski support Kemar Roofe.
In response to the goals Lampard emptied his bench with Mason Bennett making his first appearance since returning from a loan spell at Notts County and Florian Jozefzoon making his Derby debut following a £2.75 million move from Brentford but it was to no avail.
