Roof structure repairs in Kelso
Many older roofs, in Kelso and across Scottish Borders 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.

Is Scottish Borders prone to ground movement?
Kelso, Scottish Borders: about 7,000 residents across postcode districts TD5. Nearby, we also cover Galashiels (15 miles) and Hawick (18 miles).
Shrinkable clay is less common in Scottish Borders than in south-east England. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Scottish Borders: Whinstone and sandstone mill-town houses, rural cottages and post-war estates.

Methods for roof structure repairs
Wall plate replacement
Rotten or crushed wall plates are replaced in short lengths while the rafters above are propped, and bedded on the wall in mortar. The plate is then strapped down to the masonry. It is often combined with rafter foot splices along the same run.
Best for: Rot along the eaves where rafters bear on the wall
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
From first photo to finished repair
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.
Engineer’s design where needed
Where purlins, struts or ties must be redesigned, or the roof carries a heavier covering, an independent chartered structural engineer is appointed to specify the work. We can arrange this, and their design sets the sizes and fixings.
Symptoms that point to roof structure repairs
- Struts, collars or ties cut out or missing in the loft
- Top of an outside wall leaning out at eaves level
- Horizontal cracks in the wall just below the eaves or ceiling line
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.
Frequently asked questions
How much will roof structure repairs cost in Kelso?
Guide prices for roof structure repairs in Kelso 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.
Do you cover Kelso?
Yes, Kelso is covered, along with postcode districts TD5. We also cover nearby Galashiels and Hawick.
Is the ground in Scottish Borders prone to subsidence?
The Borders are mostly older hard rock with glacial till and river gravels along the Tweed and its tributaries. Stone mill towns and rubble walls shape most structural 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.
Do roof structure repairs need building control?
Usually yes, where the structure is strengthened or altered, or the covering becomes significantly heavier. In England and Wales that falls under Part A, in Scotland it generally needs a building warrant, and in Northern Ireland council building control approves it. We deal with building control where the work needs it.
