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

We measure before we quote

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

Eaves kept clear

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

Questions about loft ventilation in Farnham

Will I get a written quote for work in Farnham?

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

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

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 a landlord in Farnham book work for a tenanted house?

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

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.
