The eaves gutter flashing serves to collect water flowing down the roof slope and direct it into the gutter, while also shielding the eaves zone. At handover, it is worth checking not only the continuity of the flashing and its laps, but above all whether water from the covering actually reaches the gutter rather than passing behind it or under the covering. Equally important is preserving the required ventilation beneath the metal sheet. The shape of the flashing should follow the specific eaves detail, not merely the width of the available sheet.

A roof without eaves is a system in which the slope ends at the façade rather than projecting beyond the wall. Before choosing this variant, check above all the roof-edge cross-section: the junction of covering, insulation and drainage. This detail determines whether water reaches the gutter rather than the wall or the space behind the insulation. It is also worth establishing how ventilation under the covering will work and whether service access to the gutter is provided. A visualisation alone will not show these details, so the design should clearly define the solution for each layer.
