Why does the ground in Leicestershire matter for roof structure repairs?
Leicestershire has Mercia Mudstone, Lias clay and glacial till across much of the county, with the Coalville and Swadlincote coalfield in the north-west. Clay soils near large trees can move with the seasons.
Parts of Leicestershire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Leicestershire: Victorian terraces in Leicester and Loughborough, inter-war semis and large post-war estates.
Which repair method suits a home in Leicestershire?
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
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
What happens when we carry out roof structure repairs in Leicestershire?
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.
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
- Ridge line dipping in the middle when seen from the street
- Daylight through the tiles, or timber that is damp, stained or crumbling
- Roof slope looking hollow or wavy between the ridge and the gutter
- Top of an outside wall leaning out at eaves level
How much will roof structure repairs cost in Leicestershire?

Do you need approval 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 Leicestershire: questions and answers
Does the ground around Leicester cause cracking?
Leicestershire has Mercia Mudstone, Lias clay and glacial till across much of the county, with the Coalville and Swadlincote coalfield in the north-west. Clay soils near large trees can move with the seasons. Parts of Leicestershire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.
How much will roof structure repairs cost in Leicestershire?
On East Midlands rates, roof structure repairs starts from about £295 per rafter, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
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.
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.
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.
