Sorry to hear about your fall, i had slipped off a portch roof a few years back (trad)
one minite i was cleaning away, then before i could blink, i was on the concrete below , took all the
guttering with me on way down, i landed backwards with my hands stopping me from braking my back on
a steep step, could have easily ended up in a wheelchair,

ive done it again on another house since, but managed to grab the window ledge.. not got that worry
now on wfp. here's a pick of the first fall that i took with phone on the next clean i done on the house. jp
