Which repair method suits a home in Leigh?
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 Leigh?
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.
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.
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
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 Leigh: questions and answers
What is the price of roof structure repairs in Leigh?
Guide prices for roof structure repairs in Leigh 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 Leigh?
Yes. We take enquiries from across Leigh, including WN7, and from nearby places such as Tyldesley and Westhoughton. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Leigh cause cracking?
Greater Manchester is mostly glacial till over sandstone and mudstone, with the Lancashire coalfield beneath much of Wigan, Bolton, Salford and parts of the east. Historic mine workings, made ground and old mill sites are common. Only an investigation can say why a particular building has moved.
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.
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.
