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 Penarth

Do you charge extra to travel to Penarth?

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

Do you take on jobs outside Penarth?

Yes. We also work in Cardiff and Barry and elsewhere in South Glamorgan.

How soon can you visit a home in Penarth?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

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.
