15 gutter & downpipe terms explained
- Fascia bracket
- The clip screwed to the fascia board that holds the gutter channel and sets its gentle slope towards the downpipe.
- Union bracket (joiner)
- The clip with internal rubber seals that joins two lengths of gutter together while allowing slight expansion and contraction.
- Running outlet
- The gutter fitting with a hole in the base that funnels water from the horizontal gutter into the top of the downpipe.
- Stop end
- The cap clipped onto the closed end of a gutter run (external stop end) or inside a fitting (internal stop end) to hold water in.
- Swan-neck (offset bend)
- Two 112.5-degree or 92.5-degree bends joined by a short pipe that brings the downpipe back from the overhanging eaves to the house wall.
- Downpipe shoe
- The angled fitting at the bottom of a rainwater downpipe that directs water neatly into the ground gulley grate.
- Gulley trap
- The ground-level drain basin with a removable grate and water seal that receives rainwater from the downpipe.
- Gutter fall (gradient)
- The slight downward slope along the fascia (typically 1 in 350 to 1 in 600) so rainwater runs cleanly to the outlet instead of ponding.
- Eaves support tray (felt tray)
- A rigid plastic tray slid under the bottom course of roof tiles so rainwater drops into the centre of the gutter even if the old underlay felt has rotted.
- Half-round gutter (112 mm)
- The standard semicircular domestic gutter profile fitted on many Irish semi-detached and terraced homes.
- Deepflow / high-capacity gutter
- A deeper semi-elliptical gutter profile that carries roughly twice the flow of standard half-round on steep or large roofs.
- Ogee (K-style) gutter
- A decorative moulded front-profile gutter with high water capacity, common on detached houses and conservatory roofs.
- Continuous aluminium gutter
- Roll-formed aluminium guttering extruded on site to the exact roof length so there are no mid-run joints to leak.
- Hedgehog / mesh gutter guard
- A cylindrical bristle brush or clip-in mesh fitted along the gutter to stop autumn leaves blocking the running outlet.
- SkyVac / high-reach gutter vacuum
- A commercial wet-and-dry vacuum with lightweight carbon-fibre poles and a wireless camera used to clear gutters from ground level.
