Visiting Roda took the lead through Sanharib Malki after six minutes but goals from Bart Van Hintum (10) and Youness Mokhtar (32) saw PEC come roaring back.
Roda equalised through Bart Biemans 10 minutes before the interval but the hosts made sure of a win that takes them four points clear of danger when Denni Avdic netted 17 minutes from time.
PEC, promoted last season as champions of the Eerste Divisie, began the night just one point and one place above Roda, but are now up to 12th place after their seventh win of the campaign.
Roda remain third-bottom, mired in the relegation play-off zone.
