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.

  • Soffit, tile or ridge vents as specified
  • A note of air leaks from the house that need sealing
  • Eaves trays where insulation could block airflow

Questions about loft ventilation in Hertford

Will I get a written quote for work in Hertford?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Do you cover all of SG13?

Yes, we cover the SG13 postcode district and the districts around Hertford.

Is loft work in Hertford 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.

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.

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.
