Best Types of Roof Vents for Houses

Roof vents are becoming more and more important for modern day houses.

Because new builds require roof tile ventilation to pass building regulations, and owners of older homes are installing roof vents to improve ventilation.

There are many different types of roof vents for houses on the market.

And each option has its good and bad points, which I'm going to point out and use to give a rating out of five.

But what are the best types of roof vents? Let's quickly go through them here to save you some time.

In fact, I'll save you even more time by giving you the best ones first.

 

Best Types of Roof Vents for Houses

1. Roof Tile Vents

Roof tile vents are by far the easiest professional solution to roof ventilation problems.

They are easy to fit either during the process of installing a new roof, or retrofitting to older existing roofs. One vent replaces one tile.

There are roof tile vents designed to fit most tile profiles on the market.

You can buy them in the same colour as your existing roof tiles to maintain the appearance of your roof.

If you're venting your extractor fan through your roof, a roof tile vent is almost certainly your best solution. They're an excellent way to stop bathroom condensation.

2. Slate Vents

Slate vents are specifically designed to replace the slates on a slate roof.

Slates come in 2 standard sizes - 600 x 300mm (24 x 12 inch) and 500 x 250 mm (20 x 10 inch).

You can get them in plastic and sometimes real slate. They have a grille and underbase that allow air to flow through the vent and out of the roof. 

Most slate vents have the option of a pipe adaptor fitting to create a connection for bathroom extractor fans and soil vent pipes.

A cowl vent is a hooded roof tile vent designed to replace existing roof tiles.
They can also be connected to a bathroom extractor fan using a flexible pipe adaptor.

 Pros Cons
Easy to install Doesn't look great
Prevents draughts and wind-driven rain Breaks appearance of roof
Prevents entry of bugs and insects  

Cost per unit: £30 - £40

Installation cost: £150 - £250 (day rate for professional roofer)

Product rating: 

 

4. Lap Vents

Lap vents slip in between an overlap in the horizontal under-sarking inside the loft, providing an air path for the wind blowing up the face of the roof outside.

Pros Cons
Simple, easy, and effective Safe floor in loft needed to work on for internal fitting
Can install from inside - no need for external access or getting on the ladder Might not provide as much ventilation as roof ventilation tiles 

Cost per unit: £2 (multiple quantity needed)

Installation cost: £150 - £250 (day rate for professional roofer)

Product rating: 

 

5. Fascia Vents

Fascia vents are installed over the fascia boards to provide low level ventilation.

They could offer a better alternative to soffit vents, because soffit vents can accumulate dust and debris.

This can require regular maintenance and cleaning work.

Pros Cons
Can't see them like soffit vents Not an easy DIY option
Mesh keeps out insects Can leave little space for guttering install
Can be blocked by loft insulation 

Cost per unit: £2 - £4 per metre length

Installation cost: £150-£250 (day rate for professional roofer)

Product rating: 

 

6. Soffit Vents

Soffit vents are installed under the eaves of a roof.

They let fresh air up into the loft to improve air circulation. This prevents loft air from going stale.

When combined with roof ventilation tiles they work efficiently to draw air in through the soffit vents and exhaust warmer air through the ventilation tiles.

Pros Cons
Easy to install Designed for air intake
Unlikely to be blocked by snow Different roof vents needed to exhaust air 

Cost (singular): £0.50 - £1 (multiple quantity needed)

Cost (continuous): £5 - £10 per 2.4 metre length

Installation cost: £150-£250 (day rate for professional roofer)

Product rating: ⭐⭐

 

7. Dry Ridge Vents

Dry ridge vents can be used on the apex of a roof to provide high level ventilation and exhaust moisture.

Dry ridge vents aren’t really designed to be used as vents alone. They are more of an exit point than a source of ventilation.

They can be used in combination with other forms of lower level ventilation such as eaves vents or soffit vents, fascia vents, or roof ventilation tiles.

Pros Cons
If positioned on the apex of the roof with the felt or under-sarking suitably cut immediately beneath, they do provide excellent natural air movement If you live in an exposed location and have large soffit vents as well, ridge tile vents have been known to cause too much ventilation on very windy days, possibly blowing the insulation about near the edges

 Cost per unit: £40 - £60 

Installation cost: £150-£250

Keep in mind that ridge vents may require scaffolding to install, which could increase costs significantly.
