Roof structure repairs in Oswestry
A dipping ridge or a wavy roof slope in Oswestry is usually a timber problem, not a tile problem. We look at the rafters, purlins, struts and ties from the loft, and at the wall heads from outside, before suggesting how to strengthen it.

How do local ground conditions affect roof structure repairs in Oswestry?
Oswestry is in Shropshire and takes in postcode districts SY11. About 19,000 people live there. Nearby, we also cover Shrewsbury (16 miles) and Chester (24 miles).
Shropshire has a mix of ground, with clay in some places and firmer rock in others. Parts of Shropshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Shropshire: Timber-framed and brick town houses, industrial terraces around Telford, and new-town estates.
What happens when we carry out roof structure repairs in Oswestry?
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.

Which repair method suits a home in Oswestry?
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
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 Oswestry: questions and answers
How much will roof structure repairs cost in Oswestry?
Guide prices for roof structure repairs in Oswestry start from about £300 per rafter, including VAT, on West Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Oswestry?
Yes, Oswestry is covered, along with postcode districts SY11. We also cover nearby Shrewsbury and Chester.
Is the ground in Shropshire prone to subsidence?
Shropshire has very varied rock, from Mercia Mudstone on the north Shropshire plain to the Coalbrookdale coalfield under Telford, where historic shallow coal, clay and ironstone workings are widespread. Only an investigation can say why a particular building has moved.
Why are there cracks just below the eaves?
A horizontal crack just below the eaves, along the front or back wall, is a common sign of roof spread. The rafters push the top of the wall outward and the masonry cracks where it hinges. Corroded wall ties can cause similar cracks, so the cause needs checking.
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.
