How Do You Re-Roof a Post-War Estate House in Caerphilly?

Around Caerphilly, Llanbradach and Ystrad Mynach you find plenty of estate houses built after the war, usually semi-detached or in short terraces under concrete tiles. They were built quickly and the roofs now show it. A full re-roof is a straightforward job when done in the right order. Here is how we approach one, and what you should expect to see happen on site.

Survey before anything is ordered

We start from the ground, the loft and the gutter line. We look at the tile condition, the sag of the roof line, the state of the rafters and any damp in the loft. Nothing is ordered or quoted until we have seen the structure under the tiles. Estate roofs of this era often have thin felt, narrow battens and lightly fixed tiles, so what looks like a tile problem is frequently a whole-roof problem.

Stripping and checking the timbers

The old tiles, battens and felt come off section by section, and the roof is covered as we go so the house stays dry overnight. Once the rafters are bare we check them for rot, woodworm and movement, and repair or replace anything that is not sound. This is the stage where hidden faults appear, and we show you what we find rather than assume.

What goes back on

The sequence on a typical estate house is simple and repeatable. Each layer has a job, and skipping one is how a new roof ends up failing early, so we do not cut corners on any of them. The main stages are: Every layer is checked before the next goes on, and you are welcome to ask what is being used.

• New breathable underlay laid over the rafters
• Treated battens fixed to suit the chosen tile
• New tiles fixed to the exposure, with edge tiles clipped
• Ridge, hips and verges bedded and mechanically secured

Chimneys, party walls and details

Semis and short terraces share walls, so the junction at the party wall and the flashing round any chimney are checked and renewed. Lead replaces failed cement fillets and tired flashings, which is where many estate roofs first start to leak. Fascias, soffits and guttering are easy to renew while the scaffold is up, so we raise that at survey rather than as an afterthought. Getting these details right is what keeps the new roof dry.

Tile choice and keeping the street looking right

Many estates were laid out with a uniform roofline. Modern concrete or slate-effect tiles can match the look closely, and a neighbour on a shared roof may affect the choice. We talk through options and how the finished roof sits against the houses either side. A change of covering may need planning or Building Regulations checks — we advise before work starts. Older estates around Nelson and Llanbradach often share a pattern, which makes matching straightforward.
