Most terraced houses around Tonypandy were put up in the late 1800s, in long rows with a shared roofline and party walls running up between the homes. That shapes how a re-roof is done. You cannot treat one house as if it stood alone, so the work is planned around the wall lines, the neighbours and the weather that comes up the valley.
Start with a survey, not a quote on the doorstep
Before anything is priced we look at the roof from the street, from the loft and along the gutter line. We check the slope for sagging, the loft for daylight and damp staining, and the rafters and purlins for soft or darkened timber. Where we need a closer look, we arrange a proper survey. You get a written scope saying what comes off, what stays and what is replaced like for like.
Stripping the old covering in sections
On a terrace we strip in small sections and re-cover each one before the day ends, so the house is never left open to a valley shower. Old slate, nails and battens come off and the debris goes down a chute. Stripping also shows what a survey could not: rot at the wall plate, decayed rafter feet and tired timber near chimneys. We show you what we find first.
Timber repairs and the underlayer
Sound rafters stay. Those that have gone are replaced or strengthened alongside, and the wall plate is made good. This is hard to see afterwards, so we show you. A modern breathable membrane then goes over the rafters. Old terraces often had nothing under the slate, so this layer catches wind-blown rain and lets the loft breathe.
- Replace rotten rafter feet and wall plate sections before anything is fixed down
- Lay the membrane with proper laps and drainage to the gutter
- Fit new treated battens set to the gauge of the chosen slate
- Check the loft ventilation so condensation does not return
Party walls, chimneys and leadwork
The detail where one house meets the next decides whether a terrace roof stays dry. Where a party wall rises above the slope, it needs a proper lead flashing or a mortar-and-flashing combination that lets the wall move without opening a gap. Chimney stacks get new lead trays, soakers and flashings, and the pointing is checked. We tell you if a stack should be rebuilt or taken down to roof level, rather than leaving a weak one under fresh slate.
The new covering, ridge and finishing off
Natural slate, fibre cement slate or a concrete tile can all suit a Rhondda terrace, and we talk through which looks right beside your neighbours. The covering is fixed to the battens with the right nails and clips for exposed hillside conditions, then ridge, hips and verges are bedded and sealed. Last come fascias, soffits and guttering if included, then a clear-up. If the work may need planning or Building Regulations checks, we advise before work starts.
