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

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 Milford Haven

How soon can you visit a home in Milford Haven?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

How do I pay for work in Milford Haven?

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 Milford Haven?

Yes. We also work in Pembroke Dock and Haverfordwest and elsewhere in Dyfed.

Will extra vents make my house colder?

No. The vents ventilate the loft above the insulation, not the rooms below.

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.
