Slate Tile Vents
The Slate Vent makes it easy to vent your loft, bathroom extractor fan or soil vent pipe.
Stopping condensation in your loft or bathroom is essential for protecting your home against damp, black mould, and even wood rot.
So if you want a healthy home and a longer-lasting roof, this is the product for you.
Why You Need Better Roof Ventilation
Loft and bathroom condensation is rising fast. Here's why:
🔥 We're making more heat (showers, washing, and central heating)
🏠 Our homes hold more heat (double glazing, loft insulation, and cavity wall insulation)
When warm air rises, it meets the cold surfaces of the ceilings or roof, and condensates into water droplets.
If you leave it until it's too late, untreated loft and bathroom condensation can lead to damp, mould growth, and wood rot.
We know what it's like to have an endless list of jobs to do in your house. But getting roof ventilation right could save you £1000's in the long run.
Inline Slate Vents are the Best Multi-Purpose Solution
The most effective way to reduce loft and bathroom condensation is to create a pathway for air to flow between the inside and outside of your home. Our inline slate vents help you do this seamlessly.
✅ Multi-purpose - Vent your loft, bathroom fan or soil vent pipe
✅ Simple installation - One vent replaces one slate
✅ Inline design - Almost disappears in your roof
✅ High-quality + durable - Built to outlast your roof
✅ 30-day returns - No questions asked

Our premium quality flexi pipe helps you connect your soil vent pipe. With a full extended length of 550 mm, it is NOT a substitute for extractor fan flexi pipe. The pipe diameter is 110 mm at both ends, with jubilee clips to secure in place.

How do Slate Tile Vents Work?
See how our Slate Tile Vent works in the image to the left (or above if you're on mobile).
Air flows through the vent via the underbase unit and grille.
Rain that enters the vent will flow out through the bottom via water channels, onto the roof tiles below.
The pipe adaptor makes an easy connection point for your bathroom extractor fan or soil vent pipe.
