Roof structure repairs in Fort William
Many older roofs, in Fort William and across Highland and Moray 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.

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
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
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.
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.
Symptoms that point to roof structure repairs
- Struts, collars or ties cut out or missing in the loft
- Horizontal cracks in the wall just below the eaves or ceiling line
- Roof slope looking hollow or wavy between the ridge and the gutter

Frequently asked questions
How much will roof structure repairs cost in Fort William?
Guide prices for roof structure repairs in Fort William 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 Fort William?
Survey visits to Fort William are by arrangement because of travel and access. We can still give a free initial view from photos, and we tell you any travel cost before a visit is booked.
Is the ground in Highland and Moray prone to subsidence?
The Highlands and Moray are hard rock and glacial deposits with little shrinkable clay; exposure, steep sites and older stone buildings drive most structural work. Only an investigation can say why a particular building has moved.
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.
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.
