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
  • Soffit, tile or ridge vents as specified
  • Eaves trays where insulation could block airflow

Questions about loft ventilation in Devizes

Can a landlord in Devizes book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Will I get a written quote for work in Devizes?

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

Can you visit Devizes 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.

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.
