worked with my uncles roofing co for a bit ,,was on roof pitched enough i needed boards and brackets,,,well i pulled nail out of bracket and board went bye bye,, i scrambled up the roof trying to grap nails sticking out the ones before cleaning off during ripoff well down i went screaming grabbed the gutter that failed fingers twisted right off in pain down into a bush feet first i got hit with shingles/debri for good measure ,,the kicker the fucking board that kicked out landed in bush before me .i landed in between board bruised the shit out of my leg,,,felt like a big fall probably 15 to 20 feet..
