Probably not. Most of that cost is having a professional sort out the specifics of your particular installation, plus paying the dudes to scramble around on your roof and actually do the work (plus the associated liability).
And even once it's all done, you take an efficiency hit because no one's roof will be at the ideal angle the way panels installed at ground level can be.
