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.

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

Why book with us in Cowbridge

Eaves kept clear

Insulation is held back from the eaves so the loft can still ventilate.

Fixed written price

The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.

We measure before we quote

Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Tidy work

Dust sheets on the route in and every bit of packaging taken away.

Questions about loft ventilation in Cowbridge

Can you visit Cowbridge outside working hours?

Do you cover all of CF71?

Yes, we cover the CF71 postcode district and the districts around Cowbridge.

What do I need to do before you arrive in Cowbridge?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

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.
