Today workmen began installing shingles on the roof. They made great progress. Sadly, they are not slate ($$) shingles, but they color match closely. As you can also see from this photo, more of the arches were placed into the window frames.
There's now a full stairway from basement to choir loft. The sections installed today were from the ground level to the loft (as shown).
Happily, they also took care of some housekeeping in and around the site filling one entire dumpster with cut lumber and trash of other kinds.
