Celebrated my 50th birthday by helping with my brother's roof in Calgary. He had cedar shakes on top of asphalt; the weather was hot and most of the bodies old or inexperienced so tear-off took a couple of days. TwinB worked valiantly for the first morning, developed heatstroke as usual and took a good 36 hours to fully recover.
Found some interesting things up there such as an old bone probably from a cow (just a small section that some bird had lifted from someone's garbage) and the hind leg from a very young jack rabbit. There was so much good composty dirt under the shakes that ('nother)brother Alex and I agreed that the simplest solution would be to start a roof top garden right there with the supplies at hand.
