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 Greenwich

Will I get a written quote for work in Greenwich?

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

Can a landlord in Greenwich book work for a tenanted house?

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

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

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.

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.
