Now I'm wondering if the system is too small...

SIZE: Go as big as your roof permits OR to the limits of the rebates/tax credits. You (or the leasee) don't want to bear the full costs of the PV size above rebates. I was limited to as 3.45KW system by the rebates not the roof area.
ROOFING: yes replacing a roof can be an issue, make sure the current roof surface will last 20+ years. I had new 40yr shingles installed a couple years before installing the PV array.
SNOW: I am able most of the time to accelerate the removal of snow from the panels manually, if you don't you might lose several days production on decent sized storms.
SHADE: check not only your own property but trees in the neighbor's yard might cast a shadow, especially this time of year, not that you can do anything about it.
