Over-grown pear tree
We have a pear tree that was already too high to harvest when we moved in years ago. Now it is so tall it's dropping pears on the second story roof; not good for the roof or the nerves. We need to do something; I'd prefer not to have to cut it down and lose it. I'd love to cut it back and see if we can revive it at a harvestable height like they do for over-grown orchards. Is it possible? When and how should we do it?

You are going to want to do a crown reduction to reduce the height of the tree (this is best done when the tree is dormant (late winter/early spring).
I am attaching information from the U on pruning (see the section Pruning large established trees): https://www.extension.umn.edu/garden/yard-garden/trees-shrubs/pruning-trees-shrubs/#large-establishe...
If the tree is very large, you might consider hiring a tree service (be sure to ask if they are experienced pruning fruit trees) or a certified arborist: http://www.extension.umn.edu/garden/yard-garden/trees-shrubs/how-to-hire-a-professional-arborist/
