What is the ground like in Merseyside?
Postcode districts L20, L21, L22 cover Bootle, a Merseyside town of about 58,000 people. If you are just outside Bootle, we also cover Wallasey (4 miles), Fazakerley (4 miles) and Liverpool (4 miles).
Merseyside has a mix of ground, with clay in some places and firmer rock in others. Parts of Merseyside lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Merseyside, most homes are Victorian terraces and villas, inter-war council estates and post-war semis.

How we usually approach roof structure repairs
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
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
What happens during roof structure repairs, step by step?
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.
What to look for before calling about roof structure repairs
- Top of an outside wall leaning out at eaves level
- Daylight through the tiles, or timber that is damp, stained or crumbling
- Roof slope looking hollow or wavy between the ridge and the gutter
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 Bootle
What is the price of roof structure repairs in Bootle?
Guide prices for roof structure repairs in Bootle 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 Bootle?
We do. Bootle and the surrounding area are covered, including nearby Wallasey and Fazakerley. A free initial assessment from your photos is the first step.
Does the ground around Bootle cause cracking?
Merseyside is mostly sandstone with glacial till on top, with soft coastal deposits in Sefton and the Lancashire coalfield extending under St Helens and parts of Knowsley. Old docks and industry left made ground in places. 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.
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.
