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

Questions about loft ventilation in Weymouth

Will I get a written quote for work in Weymouth?

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 Weymouth?

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

Do you cover all of DT4?

Yes, we cover the DT4 postcode district and the districts around Weymouth.

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.
