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.

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

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.
