In latest reportlab there are new Programming Flowables which allow condifitonal 
execution based on the state of the current doctemplate and frame etc etc.

I think you should be able to use something like

DocIf('string boolean expression',[thenflowables],[elseflowables])

ie


story.append(DocIf('doc.frame.atTop',[Paragraph('sectionhead...',style=headingStyle)]))

prior to your lead paragraph for each section.
