A concealed gutter is an internal gutter that is not visible from the street; it sits behind a fascia or cornice, or within the plane of the roof itself. Concealed gutters keep the roofline clean and uninterrupted, which is why they are often chosen for buildings with a strong architectural profile.
Types
Concealed gutters take several forms depending on where they are hidden:
- Behind a fascia — the gutter tucks in behind the fascia board so only the roof edge is seen
- Behind a cornice or parapet — the gutter runs behind a decorative cornice or a raised parapet wall
- Within the roof plane — a box gutter set into a valley or between two roof slopes
- Secret gutter — a narrow gutter concealed within the roof covering itself
Application
Advantages
- A clean, uninterrupted roofline with no visible gutter
- Preferred on traditional and high-status buildings
Points to watch
- Concealed gutters are harder to inspect and clean
- A leak can allow water into the structure before it is noticed
- Adequate falls, generous outlets and reliable waterproofing are essential
