What should you know about the ground under Aberdeen?
Postcode districts AB10, AB11, AB12, AB15, AB16 cover Aberdeen, a Aberdeen and Aberdeenshire town of about 200,000 people. If you are just outside Aberdeen, we also cover Westhill (7 miles), Stonehaven (13 miles) and Inverurie (14 miles).
Clay shrinkage is less of a concern in Aberdeen and Aberdeenshire, so other causes such as drains, poor footings or older walls are checked first. Ground movement here is more often linked to soils, drains and trees than to mining. Across Aberdeen and Aberdeenshire, most homes are granite tenements and terraces in Aberdeen, fishing-town cottages and post-war estates.
How we usually approach roof structure repairs
Repairing or doubling rafters
Cracked, sagging or rotten rafters are strengthened by fixing a new timber alongside, often called doubling, and rotten rafter feet are cut back and spliced. The work is usually done from inside the loft with the tiles left in place, unless the covering is coming off anyway.
Best for: Individual rafters that have cracked, sagged or rotted at the feet
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
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.
Loft and outside survey
On site we check rafter sizes and spacing, purlins, struts, ties and wall plates, look for rot and past alterations, and measure any lean at the wall head. The covering is noted too, because its weight affects the repair.
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.
What to look for before calling about roof structure repairs
- Horizontal cracks in the wall just below the eaves or ceiling line
- Struts, collars or ties cut out or missing in the loft
- Daylight through the tiles, or timber that is damp, stained or crumbling

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 Aberdeen
What is the price of roof structure repairs in Aberdeen?
Guide prices for roof structure repairs in Aberdeen start from about £285 per rafter, including VAT, on Scotland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Does the ground around Aberdeen cause cracking?
The north-east is mostly granite and other hard rock with glacial till and sands, so clay shrinkage is uncommon. Granite buildings, older lime mortars and coastal exposure shape most repairs. Only an investigation can say why a particular building has moved.
Why are there cracks just below the eaves?
A horizontal crack just below the eaves, along the front or back wall, is a common sign of roof spread. The rafters push the top of the wall outward and the masonry cracks where it hinges. Corroded wall ties can cause similar cracks, so the cause needs checking.
What is roof spread?
Roof spread is when the feet of the rafters move outward because nothing is tying them together firmly enough. As they spread, the ridge drops and the tops of the walls are pushed out, often with a horizontal crack below the eaves. It is fixed by adding ties, collars or straps, sometimes with rebuilding.
