The volunteers are not doing roofing. They're installing trim and
fixing punch-list items. There are _always_ lots of punch-list items.
("We do it right the last time.")
As far as the shingles go, all I can tell you is that walking on them
by people who aren't careful sometimes causes enough damage that the
roof fails a final inspection. Besides, the rule for making punch-lists
is, "How would you want it if it were your house?")
