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.

  • Eaves trays where insulation could block airflow
  • Soffit, tile or ridge vents as specified
  • A note of air leaks from the house that need sealing

Why book with us in Winchester

Eaves kept clear

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

We measure before we quote

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

Fixed written price

The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.

Questions about loft ventilation in Winchester

Is loft work in Winchester different from anywhere else?

The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.

Will I get a written quote for work in Winchester?

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

Do you charge extra to travel to Winchester?

Not normally. Our guide prices include normal travel to Winchester. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

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.
