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 Antrim

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

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.

Can you visit Antrim outside working hours?

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.

How soon can you visit a home in Antrim?

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.

My bathroom fan vents into the loft. Is that a problem?

Yes. It pumps warm, wet air straight into the coldest part of the house. The duct should run to outside through a vent tile, soffit or wall.

Will extra vents make my house colder?

No. The vents ventilate the loft above the insulation, not the rooms below.
