In the process of doing this work, she discovered yet more holes in the roof near the chimney. Upon coming back down from the roof, and taking stock of the rate of progress and the fact that I have to leave by mid-day Saturday, she decided that the original plan to cover the entire roof was too ambitious. We went to the hardware store, bought some specialized sheeting for roof repairs and some roof-repair goop that can only be used in hot, dry weather like we're having now. The new plan is to try and do something just to the approximately three-meter-wide space down-roof from the chimney, and the area immediately around the chimney itself. With luck, she figures she can get the lathe strips down later today, and maybe even get the plastic sheets stapled into place. However, before she can do that, she plans to take the leaf blower up there and blow most of the rest of the moss that she'd loosened with the wire brush off the roof.
I had to go back to the "office" and work later today on account of the long lunch. That's okay, though, because she needed time to cool off and decompress after the hour on the roof, and she won't want to go back up there until later this evening. The long days here mean that we can work until almost 8:30 PM. Also, the weather is slightly cooler today than it was yesterday.
