Three Different Types of Roof Vents

A roof should be well ventilated to stop damp causing damage to timbers. While modern breathable membranes allow an amazing amount of moisture to vent through to the layer above, good circulation of air is always helpful in reducing the moisture levels under the roof and preventing mold and rot damage.

One of the key tools in a roofers armoury against moisture is the roof vent which will allow air to pass through the tile or slate layer and yet will keep out rain, even when strong winds might threaten. To get enough air through a roof, it's important to use vents in the roof line to allow air to flow freely through the structure.

Flush tile vents

One of the most commonly used vents in a roof is a simple tile vent. The tile vent takes the place of one of the tiles in your roof and allows air to get in but keeps moisture out. There are a wide range of tile vents available, suitable for use with different types of roof tiles.

Flat roof vents

Flat roof vents are usually small dome shaped structures that allow the internal roof space under a flat roof to breathe. They should be fitted when the roof is refitted with torch-on roofing felt, so the roof maintains its watertight seal.

Soffit vents

Soffit vents fit neatly under the eaves in place of standard sealed soffit board. They are usually made from aluminium and can either be clipped or screwed into place. The continuous vents allow air into the roof under the soffit, reducing the potential for damp.

Roof Vents are simple but remarkably effective at greatly increasing the flow of air under the roof and are essential, especially if you have problems in venting sufficient moisture from under your roof space. They are inexpensive and easy to fit with fixtures for every type of roof.
