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
Why book with us in Larne
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
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.
Clear contact details
Your quote says who to call with questions before, during and after the work.
How much does loft ventilation cost in Larne?
This work is not an energy-saving material for VAT, so it is standard-rated if VAT applies. Where it is done alongside insulation, the quote shows each part separately.
Building regulations in Northern Ireland
Northern Ireland has its own Building Regulations, with energy guidance in Technical Booklet F1. Upgrading loft insulation may count as a thermal alteration, so check with your council's building control. How the rules work across the UK.
Questions about loft ventilation in Larne
Will I get a written quote for work in Larne?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
How do I pay for work in Larne?
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 Larne?
Yes. We also work in Carrickfergus and Newtownabbey and elsewhere in County Antrim.
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.
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.
