Roof structure repairs in Sudbury
If the top of a wall at your Sudbury property seems to lean out at the eaves, the roof may be spreading. Ties, collars and straps can usually hold it back, sometimes with an engineer’s design for the new load path.

What should you know about the ground under Sudbury?
Sudbury (CO10) has around 24,000 residents and sits in Suffolk. Neighbouring towns we cover: Colchester (13 miles), Haverhill (13 miles) and Braintree (13 miles).
Shrinkable clay is widespread in Suffolk. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Suffolk: Timber-framed and flint cottages, Victorian terraces in Ipswich and Lowestoft, and post-war estates.
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.
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.

Repair options we may recommend
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
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
How much should I budget for roof structure repairs in Sudbury?
Guide prices for roof structure repairs in Sudbury start from about £315 per rafter, including VAT, on East of England rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Sudbury?
We do. Sudbury and the surrounding area are covered, including nearby Colchester and Haverhill. A free initial assessment from your photos is the first step.
Why do houses in Suffolk crack?
Much of Suffolk is chalky boulder clay, with London Clay around Ipswich and Felixstowe and sandier ground in the Breckland and on the coast. The clay areas are prone to seasonal shrinkage near trees. Only an investigation can say why a particular building has moved.
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.
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.
