What should you know about the ground under Maidenhead?

With roughly 70,000 people, Maidenhead spans postcode districts SL6 in Berkshire. Nearby places we cover include Marlow (4 miles), Slough (5 miles) and High Wycombe (7 miles).

Shrinkable clay is widespread in Berkshire. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Berkshire: Victorian and Edwardian terraces in Reading and Windsor, 1930s semis, and large post-war new-town estates around Bracknell.

Symptoms that point to roof structure repairs

  • Top of an outside wall leaning out at eaves level
  • Struts, collars or ties cut out or missing in the loft
  • Daylight through the tiles, or timber that is damp, stained or crumbling

Methods for roof structure repairs

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

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

From first photo to finished repair

  1. 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.

  2. 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.

  3. 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.

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.

Frequently asked questions

What is the price of roof structure repairs in Maidenhead?

Guide prices for roof structure repairs in Maidenhead 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 Maidenhead?

Yes, Maidenhead is covered, along with postcode districts SL6. We also cover nearby Marlow and Slough.

Does the ground around Maidenhead cause cracking?

East Berkshire is largely London Clay with Thames terrace gravels along the river, while the west rises onto chalk downland. Houses on the clay near Slough, Windsor and Bracknell are the ones most exposed to shrink-swell movement. Only an investigation can say why a particular building has moved.

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.

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.
