Roof vent cost
Enabling air circulation in your loft is just as vital as boarding your loft and insulating it properly. So, if condensation’s present in your loft space, installing roof vents will combat this as well as keep the air circulating correctly for a more regulated temperature.
If you spot condensation in your loft (particularly during the colder months between November and February), your roof probably isn’t ventilated correctly. You also may have noticed water droplets (often called “roof sweating”) or even damp patches. Perhaps it smells musty or you’ve spied mould growing on boxes stored in your loft space.

Fitting roof vents stop loft spaces from becoming too warm or too cold and help prevent moisture build-up.
Enabling air circulation in your loft is just as vital as boarding your loft and insulating it properly. So, if condensation’s present in your loft space, installing roof vents will combat this as well as keeping the air circulating correctly for a more regulated temperature.
If you’re having a new roof installed, it’s also worth mentioning to your roofer about having loft vents installed at the same time, as doing so will prevent issues further along the line.
Roof vent costs
Roof ventilation costs start at around £250 for 20 circular/eaves vents – this would include fitting them in the front and back of your terraced or semi-detached house.
To fit four roof vent tiles, you’d be looking at a price of roughly £400, while fitting four ridge vents to a standard house would cost about £350.
There are three kinds of loft vents available, so we advise fitting a minimum of one type, but it’s best to fit two types, as all three would be a little too much.
Roof vent installation costs
A roofer will typically charge £150 – £250 per day and, normally, they’ll work in pairs to carry out the task safely and efficiently.
Roof ridge vent installation cost
It costs roughly £650 for a roofer to fit four roof ridge vents and 20 eaves vents to a two-storey semi-detached property, plus a day’s labour. The overall price will depend on the size, type, and the number of units you want fitting.
Roof vent repair cost
On average, a roofer will charge £650 to repair four tiles and 20 eaves vents.

What kinds of roof vents are available?
There are three types of loft or roof vents to consider:
- Ridge vents – positioned at the roof’s highest point (the ridge).
- Tile vents – replace tiles mid-roof and work well with most roof tiles in the UK market.
- Eaves/soffit vents – circular vents that are often fitted together with ridge vents for extra ventilation to enable airflow to the loft.
If you’re worried about the ventilation in your loft, it may be worth having soffit vents installed. These types of vents are fitted underneath the eaves of your roof to enable fresh air to pass into your loft.
