Jonathan Forte scored twice in 20 minutes to bring his total since arriving on-loan from Scunthorpe to six goals in seven games before Delroy Facey added a third in first-half added time.
Bradford, who had been thrashed 4-1 by lowly Barnet in their last fixture, got a late consolation from Peter Thorne but it did little to dampen the mood of McParland.
He said: "I'm delighted with the performance and I will be able to enjoy my weekend now. At times we made Bradford look ordinary.
"Jonathan Forte has been terrific for us and I said to him after training during the week that if he performed like that he would get a couple of goals - and I was right.
"It was a disappointment we couldn't keep a clean sheet, but we've now won four in five at home and once you get a couple of results under your belt the confidence grows. We want to please the supporters with the football we play and the results we get and we are doing that at the moment."
