Is West Sussex prone to ground movement?
With roughly 34,000 people, Haywards Heath spans postcode districts RH16 in West Sussex. Nearby, we also cover Burgess Hill (3 miles), Crawley (9 miles) and Uckfield (9 miles).
Much of West Sussex sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across West Sussex: Wealden cottages, 1930s semis and bungalows on the coast, and new-town estates in Crawley.
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.
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.
What to look for before calling about roof structure repairs
- Roof slope looking hollow or wavy between the ridge and the gutter
- Ridge line dipping in the middle when seen from the street
- Horizontal cracks in the wall just below the eaves or ceiling line

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
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
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 Haywards Heath
What is the price of roof structure repairs in Haywards Heath?
Guide prices for roof structure repairs in Haywards Heath start from about £335 per rafter, including VAT, on South East 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 Haywards Heath?
Yes, Haywards Heath is covered, along with postcode districts RH16. We also cover nearby Burgess Hill and Crawley.
Does the ground around Haywards Heath cause cracking?
North West Sussex around Crawley and Horsham sits on Weald Clay, the South Downs are chalk, and the coastal plain has brickearth and gravels. The Weald Clay is prone to shrink-swell movement near trees. Only an investigation can say why a particular building has moved.
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.
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.
