Is Lancashire prone to ground movement?
Blackpool (FY1, FY3, FY4) has around 150,000 residents and sits in Lancashire. We also take enquiries from nearby Poulton-le-Fylde (3 miles), Thornton-Cleveleys (4 miles) and Lytham St Annes (6 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. Across Lancashire, most homes are stone and brick mill terraces, seaside villas in Blackpool and Lytham, and inter-war and post-war semis.
What happens when we carry out roof structure repairs in Blackpool?
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.
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.
Signs you may need roof structure repairs
- Horizontal cracks in the wall just below the eaves or ceiling line
- Ridge line dipping in the middle when seen from the street
- Top of an outside wall leaning out at eaves level

Which repair method suits a home in Blackpool?
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
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
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.
Roof structure repairs in Blackpool: questions and answers
What is the price of roof structure repairs in Blackpool?
Guide prices for roof structure repairs in Blackpool 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.
Do you carry out roof structure repairs in Blackpool?
Yes, Blackpool is covered, along with postcode districts FY1, FY3, FY4. We also cover nearby Poulton-le-Fylde and Thornton-Cleveleys.
Does the ground around Blackpool cause cracking?
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.
Can the roof be strengthened without removing the tiles?
In most cases, yes. Doubling rafters, adding struts and fitting ties can all be done from inside the loft with the coverings in place. Tiles usually only come off where timber near the eaves is badly decayed, or the roof is being re-covered anyway.
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.
