A roof viewed from the terrace or from windows on a higher storey requires particular attention. The entire surface is then visible, along with the divisions and elements that remain almost invisible from the street. Integrated steel BIPV makes it possible to achieve an orderly roof slope without separate modules on a mounting frame. However, the layout should be planned from the user's actual viewpoint. Light reflection, service access and the way the roof is finished at its surroundings also matter. From ground level on the plot, the roof may look like a narrow dark plane. From a first-floor window or a terrace above the garage, much more is visible. The boundaries of the active fields, the flashings and the installation penetrations become apparent. The design should therefore include this view if it will be part of the residents' everyday surroundings.
