This small slate vent offers a low‑profile face that blends into the roof line while a vent cap discourages debris, birds and insects from entering. Behind the face, a built‑in downpipe allows direct ventilation to the roof space or a simple connection to flexi pipe for soil and extraction runs. The geometry keeps airflow steady to reduce condensation risk and protect timbers, and installation suits most small man‑made fibre cement or natural slate profiles. From ground level the vent reads as part of the coursing; inside the build‑up it works continuously to keep humidity moving out. Choose the small slate vent when you want discreet presentation with dependable performance and a connection detail that stays tidy.
