Today the roof got removed! Nice weather for it, clear and cool. Hopefully it doesn't rain for a while now.
Next we have to raise the level of the walls, which are made out of concrete block, pour a "bond beam" with concrete and rebar around the top perimeter, and enlarge openings for the new windows.
Evidently rebar is in short supply in Ottawa right now. Hopefully it won't cause too many delays because the block work and bond beam needs to be done before the framing for the second storey and new roof can start.
With the new foundation poured, the backfill in, and the roof off, it looks like things are finally starting to progress in the upwards direction on our renovation.
