What is loft ventilation?

Most pitched roofs are ventilated at the eaves, sometimes with high-level vents as well. Insulation pushed into the eaves can block that path, which is why we fit ventilation trays. 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 Hampshire

How do I book a survey in Hampshire?

Send the form or call us. We call back to agree a time and confirm it in writing.

Can you quote for several properties in Hampshire?

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

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.

Will extra vents make my house colder?

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