Cheshire has a mix of ground, with clay in some places and firmer rock in others. Historic brine and salt working has caused ground movement in parts of Cheshire in the past. Across Cheshire, most homes are brick terraces in Crewe, Northwich and Warrington, Victorian villas in Chester, and inter-war and post-war semis.
What to expect when we carry out roof structure repairs
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.
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.

Repair options we may recommend
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.
Your roof structure repairs questions
What is the price of roof structure repairs in Warrington?
Guide prices for roof structure repairs in Warrington 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 Warrington?
Yes, Warrington is covered, along with postcode districts WA1, WA2, WA4. We also cover nearby Widnes and Ashton-in-Makerfield.
Does the ground around Warrington cause cracking?
Most of Cheshire is glacial till over Mercia Mudstone. Around Northwich and the Weaver valley, historic salt and brine extraction has caused subsidence in the past, and a separate brine subsidence compensation scheme exists for parts of the county. 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.
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.
