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.

  • 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 Nailsea

Do you take on jobs outside Nailsea?

Yes. We also work in Portishead and Clevedon and elsewhere in Somerset.

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

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.

Do you cover all of BS48?

Yes, we cover the BS48 postcode district and the districts around Nailsea.

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.
