edge similar to bond beam panels fig5 b there is no need for all the structural reinforcing at the gutter location as aac is strong enough by itself an angled routed groove 44 may be added to the aac panels to transmit moisture out of the roof assembly and act as an integrated gutter system to gutter box 46 hereof no prior art of cementitious materials with integrated gutter systems employ a gravity driven water removal method all prior art relies on inferior water pressure method as subsequent water forces previous water toward down spout box and off the roof the prior art 39 s use of water pressure has negative results of residual moisture remaining in trough which eventually causes water damage due to debris build up and or freezing downspout box 46 fig4 d disperses moisture out and away from habitat by curved wall and wide slot at base the interior ridges and various platform heights of curved wall near slot break up the mass of water into smaller droplets so as it is propelled out of box large volumes of water do not overburden any one area too much finally the facia water deflection system 45 is one and the same material as the roofing and is one continuous niece of roofing material specifically shaped to have reversing angles with a series of sharp angles so it is impossible for water coming off the roof to run down its face but rather gravity pulls water off its face at several different places which not only deflects water away from house.
