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.

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

Questions about loft ventilation in Calne

Is loft work in Calne 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 SN11?

Yes, we cover the SN11 postcode district and the districts around Calne.

Do you charge extra to travel to Calne?

Not normally. Our guide prices include normal travel to Calne. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Will extra vents make my house colder?

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

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.
