Check the weather...
I waited for the optimal day to go through the roof; clear skies, no chance of rain, sunny, and the hottest day of the year to date. It was hot in the house, hotter on the roof, and ridiculous in the crawlspace. I had to be sure that the adhesive and the caulking would have enough time to set before a storm. The sample from the roof was about five inches thick, mostly tar and rocks, and probably weighs close to twenty pounds. Now that I have officially passed through every floor and the roof, the next step is to resolve the shelves loaded with board games on the first floor. I'll only be here at Elsewhere for three more working days and I still have a lot of work to do.
