Roofs in Paisley that were re-covered with heavier concrete tiles, or had struts cut out for a loft room, often start to sag years later. Spotting which change caused the movement is the first step to a repair that holds.

Is Renfrewshire and Inverclyde prone to ground movement?
Paisley, Renfrewshire and Inverclyde: about 77,000 residents across postcode districts PA1, PA2, PA3. Neighbouring towns we cover: Barrhead (3 miles), Renfrew (3 miles) and Johnstone (3 miles).
Most of Renfrewshire and Inverclyde is on firmer ground than the clay belts of the south-east. Parts of Renfrewshire and Inverclyde lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Renfrewshire and Inverclyde: Sandstone tenements, villas in East Renfrewshire, and post-war estates.
From first photo to finished repair
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.
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
- 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

Methods for roof structure repairs
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
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
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
What is the price of roof structure repairs in Paisley?
Guide prices for roof structure repairs in Paisley 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 carry out roof structure repairs in Paisley?
Yes. We take enquiries from across Paisley, including PA1, PA2, PA3, and from nearby places such as Barrhead and Renfrew. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Paisley cause cracking?
Renfrewshire has glacial till and Clyde alluvium with coal workings recorded in parts, while Inverclyde's towns climb steep slopes above the Clyde with many retaining walls. Only an investigation can say why a particular building has moved.
Do I need a structural engineer for roof repairs?
For like-for-like repairs to a few rafters, often not. Where purlins, struts or ties are being redesigned, the covering is getting heavier or the walls are being pushed out, you usually do. Where the repair needs an engineer’s design or sign-off, an independent chartered structural engineer is appointed, and we can arrange this.
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.
