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.

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

Questions about loft ventilation in Greater London

Are your prices the same across Greater London?

Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.

Can you quote for several properties in Greater London?

Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.

Will extra vents make my house colder?

No. The vents ventilate the loft above the insulation, not the rooms below.

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.
