What should you know about the ground under Brecon?

Postcode districts LD3 cover Brecon, a Powys town of about 8,000 people. Nearby places we cover include Merthyr Tydfil (14 miles), Ebbw Vale (14 miles) and Aberdare (16 miles).

Shrinkable clay is less common in Powys than in south-east England. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Powys: Stone farmhouses and cottages, market-town terraces and small 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 Wales

In Wales, the Welsh version of the Building Regulations applies. Underpinning and other work that alters or strengthens the structure needs building control approval and inspection; like-for-like repairs often do not. The Party Wall etc. Act 1996 applies to work on party walls and excavation close to a neighbour’s foundations.

Your roof structure repairs questions

How much will roof structure repairs cost in Brecon?

Guide prices for roof structure repairs in Brecon start from about £275 per rafter, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Do you cover Brecon?

Survey visits to Brecon are by arrangement because of travel and access. We can still give a free initial view from photos, and we tell you any travel cost before a visit is booked.

Is the ground in Powys prone to subsidence?

Powys is largely older hard rock and glacial deposits, with alluvium in the river valleys. Clay shrinkage is uncommon, but older stone buildings and rubble walls bring their own structural issues. 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.

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.
