We were making a trench cut on a 3 story apartment building the other day on the fire side of a firewall. The problem we ran into was that the roofing material ran about 10" to 12" and after making the 2 parrell cuts 4' apart through the 2 foam layers of insulation and pea rock we tried to remove that material. At one point we had about 15 men on the roof working on this. We were only able to open several small holes-none large enough to apply a master stream. Since we don't do this everyday does anyone have any tricks or tips they might have on this.
Thanks
