Roof structure repairs in Cumbernauld
Many older roofs, in Cumbernauld and across Lanarkshire 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 Lanarkshire prone to ground movement?
Postcode districts G67 cover Cumbernauld, a Lanarkshire town of about 51,000 people. If you are just outside Cumbernauld, we also cover Coatbridge (6 miles), Kirkintilloch (6 miles) and Falkirk (9 miles).
Clay shrinkage is less of a concern in Lanarkshire, so other causes such as drains, poor footings or older walls are checked first. Historic coal workings are recorded beneath parts of Lanarkshire, and a coal mining search is worth checking where movement is unexplained. Across Lanarkshire, most homes are miners' rows, sandstone tenements, inter-war council houses and new-town estates in East Kilbride and Cumbernauld.

Methods for 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
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

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.
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.
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 Cumbernauld?
Guide prices for roof structure repairs in Cumbernauld 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 Cumbernauld?
We do. Cumbernauld and the surrounding area are covered, including nearby Coatbridge and Kirkintilloch. A free initial assessment from your photos is the first step.
Is the ground in Lanarkshire prone to subsidence?
Lanarkshire lies on the Central Coalfield, mined intensively in the past around Hamilton, Motherwell, Airdrie and Coatbridge, so recorded workings are common beneath towns. Only an investigation can say why a particular building has moved.
Is a sagging roof ridge dangerous?
A slight, even dip in an old roof is often historic movement that stopped long ago. A sag that is getting worse, cracking timbers, walls pushing out at the eaves or recently removed struts should be checked soon. Avoid storing heavy items in the loft until then.
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.
