Over the master bedroom they'll install "ventilated nailbase insulation panels". The bedroom has a cathedral ceiling with no insulation, so this allows them to put the insulation on top of the roof deck, and still have the roof vented to prevent ice dams. http://www.hpanels.com/pages/pdfs/Lit_Prod_Color/Cool-Vent.pdf (5" of foam, with a plywood, not OSB)
Oh wow, that's really cool. If we needed more done to our roof, I'd consider having something like that put on. *crosses fingers* but hopefully our roof is just the simple straight up repair job that our contractor thinks it is going to be.
