Roof structure repairs in Leyland
If the top of a wall at your Leyland property seems to lean out at the eaves, the roof may be spreading. Ties, collars and straps can usually hold it back, sometimes with an engineer’s design for the new load path.

Is Lancashire prone to ground movement?
Postcode districts PR25, PR26 cover Leyland, a Lancashire town of about 38,000 people. We also take enquiries from nearby Chorley (4 miles), Preston (5 miles) and Horwich (9 miles).
Lancashire has a mix of ground, with clay in some places and firmer rock in others. Parts of Lancashire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Lancashire: Stone and brick mill terraces, seaside villas in Blackpool and Lytham, and inter-war and post-war semis.
What to expect when we carry out roof structure repairs
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.

Repair options we may recommend
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 England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.
Your roof structure repairs questions
How much should I budget for roof structure repairs in Leyland?
Guide prices for roof structure repairs in Leyland start from about £290 per rafter, including VAT, on North West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Leyland?
Yes. We take enquiries from across Leyland, including PR25, PR26, and from nearby places such as Chorley and Preston. Send photos for a free initial view and we will tell you what happens next.
Why do houses in Lancashire crack?
Lancashire is mostly glacial till over sandstone and mudstone, with the Burnley and Accrington coalfield in the east and soft coastal and estuarine ground on the Fylde. Old mill and mine sites leave made ground in many towns. 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.
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.
