What is loft ventilation?
Most pitched roofs are ventilated at the eaves, sometimes with high-level vents as well. Where there are no vents, we add soffit vents, tile or slate vents, or ridge vents, depending on the roof covering and the underlay. More about loft ventilation.
- Eaves trays where insulation could block airflow
- Soffit, tile or ridge vents as specified
- A note of air leaks from the house that need sealing

Building regulations in England
In England, a loft insulated across more than half its area should reach a U-value of 0.16 W/m²K. Insulation alone is not usually notified to building control. How the rules work across the UK.
Questions about loft ventilation in Portishead
Will I get a written quote for work in Portishead?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Is loft work in Portishead different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
Do you cover all of BS20?
Yes, we cover the BS20 postcode district and the districts around Portishead.
My bathroom fan vents into the loft. Is that a problem?
Yes. It pumps warm, wet air straight into the coldest part of the house. The duct should run to outside through a vent tile, soffit or wall.
Does my loft need ventilation after insulation?
A cold loft needs a path for outside air, usually at the eaves. New insulation must not block it, which is why we fit eaves trays.
