What is the ground like in Cumbria?
Whitehaven (CA28) has around 23,000 residents and sits in Cumbria. Nearby, we also cover Workington (7 miles).
Clay shrinkage is less of a concern in Cumbria, so other causes such as drains, poor footings or older walls are checked first. Parts of Cumbria lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Cumbria: stone-built terraces and farmhouses, sandstone town houses in Carlisle and post-war estates.
How we usually approach roof structure repairs
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
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
What happens during roof structure repairs, step by step?
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.
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.
What to look for before calling about roof structure repairs
- Roof slope looking hollow or wavy between the ridge and the gutter
- Daylight through the tiles, or timber that is damp, stained or crumbling
- Horizontal cracks in the wall just below the eaves or ceiling line

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.
Questions about roof structure repairs in Whitehaven

Does the ground around Whitehaven cause cracking?
Cumbria's ground is largely hard rock and glacial deposits, with the West Cumberland coalfield around Whitehaven and Workington where historic coal workings are recorded. Stone walls and older lime mortars feature in much of the housing. Only an investigation can say why a particular building has moved.
Is a sagging roof ridge dangerous?
A slight, even dip in an old roof is often historic movement that stopped long ago. A sag that is getting worse, cracking timbers, walls pushing out at the eaves or recently removed struts should be checked soon. Avoid storing heavy items in the loft until then.
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.
