Roof structure repairs in Irvine
Many older roofs, in Irvine and across Ayrshire alike, were built with slim purlins and few ties. A little historic movement is normal, so we check whether the roof is still moving before recommending how far the strengthening needs to go.

What should you know about the ground under Irvine?
We cover Irvine and its postcode districts KA11, KA12, part of Ayrshire, with a population of roughly 34,000. Nearby, we also cover Kilwinning (3 miles), Saltcoats (5 miles) and Troon (5 miles).
Clay shrinkage is less of a concern in Ayrshire, so other causes such as drains, poor footings or older walls are checked first. Historic coal workings are recorded beneath parts of Ayrshire, and a coal mining search is worth checking where movement is unexplained. Housing stock in Ayrshire: Sandstone villas and terraces in the coastal towns, miners' rows and post-war estates.
What happens during roof structure repairs, step by step?
Send photos
Photograph the roof from across the street, both slopes if you can, and the loft timbers with a torch. Include the eaves and any cracks just below them. From these we can usually tell sag from spread and whether an engineer is needed.
Written quote
You receive a no-obligation written quote listing each timber repair, any ties or straps, propping, scaffolding and making good. Once the repair is specified, the figure becomes a fixed price in writing.
Prop, strengthen and tie
The roof is propped where members are being changed, then rafters, purlins, struts and ties are repaired or added as specified. Coverings disturbed by the work are relaid, and building control inspects where the work needs it.
What to look for before calling about roof structure repairs
- Ridge line dipping in the middle when seen from the street
- Horizontal cracks in the wall just below the eaves or ceiling line
- Roof slope looking hollow or wavy between the ridge and the gutter

How we usually approach roof structure repairs
Purlin and strut strengthening
Undersized purlins are strengthened with extra timber or replaced, and new struts are taken down to a load-bearing wall. Where there is no suitable wall, an engineer designs the load path. Temporary props hold the roof while members are changed.
Best for: Sagging slopes, slim purlins and struts removed from the loft
Tying in roof spread
New ties, collars or steel straps connect opposite rafters, or fix the rafter feet and wall plate firmly to the ceiling joists, so the outward thrust is resisted. Leaning wall heads are strapped back to the roof, and a badly spread roof may need partly rebuilding first.
Best for: Walls pushed out at eaves level by spreading rafters
Rules for roof structure repairs in Scotland
In Scotland, underpinning and other structural alterations generally need a building warrant from the council’s building standards service before work starts, and a completion certificate at the end; small like-for-like repairs often do not. There is no Party Wall Act in Scotland; shared walls are covered by title deeds and, for flats, the Tenements (Scotland) Act 2004.
Questions about roof structure repairs in Irvine

Is the ground in Ayrshire prone to subsidence?
Ayrshire has a large coalfield, especially in the east around Kilmarnock and Cumnock, with recorded workings, and raised-beach sands and gravels along the coast. Only an investigation can say why a particular building has moved.
Can heavy concrete tiles damage a roof?
Yes, if the frame was designed for lighter slate or tiles and was not strengthened. The extra weight makes rafters and purlins sag and can bring on roof spread. Before re-roofing in a heavier material, have the structure checked and notify building control.
Can the roof be strengthened without removing the tiles?
In most cases, yes. Doubling rafters, adding struts and fitting ties can all be done from inside the loft with the coverings in place. Tiles usually only come off where timber near the eaves is badly decayed, or the roof is being re-covered anyway.
