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
