This fellow has been building a cabin in, I believe, Labrador, by himself. He's quite handy, but forgot a little something when he laid his beams on his piers. Just shows the power of wind! (his language can be pretty salty...be forewarned!) The problem shows up at about 3 minutes into the video. First three minutes are about all his shingles that came off (there's also nothing between his roof sheathing and the shingles. Likely a cost-cutting measure.)
