Well as u can see its "possible" to get onto that roof i think didnt test enough, basically u get on the poles from that house at north (in SS) it might seem its blocked with invisable wall but u can get past it enoguh t get on the pole, then jump on the otehr pole as show in ss using a nade, c4 or w.e and then the next one... and finally the roof.
Grey colour = possible c4 sticky zones
Green colour = The Route to the roof
