Actually, yesterday went very well. It was slightly cooler and a little overcast, which gave Lisa an extended time on the roof without sending her into heatstroke. Yesterday afternoon, after we took my van to the dealership where they will, I hope not have to charge me a whole lot of money to deal with the service-engine light, we came back to Mehama and Lisa climbed up to the roof and laid a coat of Gray Goo on the lower section of the now-covered "gap," and now there's at least one coat of goo and roofing material on the entire forward third of the roof. Now that needs to dry for a couple of days before she can go back up and put down White Goo over that.
Meanwhile, plans are progressing for laying down more roofing cloth and roof goop on sections of the roof moving toward the back. At some point, we'll have to move the ladders and ropes, which will no doubt be a difficult production, given the roof configuration. Oh, and I think we'll have to completely cut out one of the bushes at the side of the house to give us the necessary access. But that's not really a problem. It's Oregon: the thing will surely grow back in a year or two if we give it a chance.
