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 Larne

Will I get a written quote for work in Larne?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

How do I pay for work in Larne?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

Do you take on jobs outside Larne?

Yes. We also work in Carrickfergus and Newtownabbey and elsewhere in County Antrim.

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.

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.
