What loft conversion steels involve in Armagh City, Banbridge and Craigavon
Loft conversion steels are one of the most common structural jobs in homes across Armagh City, Banbridge and Craigavon. Towns we cover include Craigavon, Banbridge and Portadown, among other places in the area. Every job starts with a survey visit, then calculations from a structural engineer, so the steel suits the house in front of us rather than a rule of thumb.
Things to plan for
- A rear dormer removes part of the roof slope, so the rafters above lose their support at the lower end. A ridge beam or a beam along the dormer's front edge carries them instead, designed for the dormer width and the weight of the roof.
- Steels supporting a loft floor commonly need 30-minute fire resistance in a typical house. That is usually achieved with fire-rated plasterboard below and around the steel, to the specification agreed with building control.
- Water tanks, cables, aerial leads and bathroom extract ducts often sit exactly where the steel needs to go. They are moved before the beams arrive, and old cold water tanks are frequently removed as part of the wider loft project.
- Getting steel into a loft is often the hardest part of the job. Beams can be brought through a roof opening, a gable window, or in shorter lengths bolted together inside, provided the engineer's design allows for the splice.
- The steel stage of a loft conversion usually takes a few working days and comes early, before floor joists, dormer framing and insulation. Keep the steel calculations with the completion certificate, as both are asked for when the house is sold.
From survey to sign-off in Armagh City, Banbridge and Craigavon
Survey in Armagh City, Banbridge and Craigavon
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
A full plans application or building notice goes to Armagh City, Banbridge and Craigavon Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Questions about loft conversion steels in Armagh City, Banbridge and Craigavon
Who approves loft conversion steels in Armagh City, Banbridge and Craigavon?
Structural work in Armagh City, Banbridge and Craigavon needs a full plans application or building notice to Armagh City, Banbridge and Craigavon Borough Council. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
Can I stay at home while the work is done in Armagh City, Banbridge and Craigavon?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
Can my loft be converted if it has trussed rafters?
Often it can, but it is a bigger structural job. Trussed rafters have diagonal webs right through the loft, and every truss that is cut needs its load picked up by new steel and timber. The engineer designs that, and the roof is propped carefully throughout.
Do loft conversion steels need fire protection?
Usually, yes. Steel loses strength in a fire, and the beams carrying the new floor are elements of structure. In a typical house they commonly need 30-minute fire resistance, often provided by fire-rated plasterboard around and below the steel, as agreed with building control.
What is a ridge beam in a loft conversion?
A ridge beam is a steel beam running along the top of the roof to support the rafters when their usual support is removed, such as when a large dormer is built or a hipped roof is converted to a gable. The engineer decides whether one is needed and specifies it.
Do all loft conversions need steel beams?
Most do, but not all. Steels are usually needed to carry the new floor, replace purlins and struts, or support the roof around a dormer. Some smaller conversions use deeper timber joists or engineered timber instead. A structural engineer decides what the roof and walls need after a survey.
What happens at the survey visit in Armagh City, Banbridge and Craigavon?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
