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
  • A note of air leaks from the house that need sealing
  • Eaves trays where insulation could block airflow

Eaves kept clear

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

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.

We measure before we quote

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

Questions about loft ventilation in Machynlleth

Can you visit Machynlleth outside working hours?

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

Do you charge extra to travel to Machynlleth?

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

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.

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.
