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

Questions about loft ventilation in Ystradgynlais
What do I need to do before you arrive in Ystradgynlais?

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.
