A coal town built in white lias and Welsh slate
Radstock was built on coal. It was found here in 1763, and for two centuries the pits shaped the town; the last two, Kilmersdon and Writhlington, closed in 1973. The housing still tells that story. Terraces were a cost-effective way to house miners on such steep ground, so rows of one-and-a-half and two-storey cottages step up the slopes of the Wellow Brook valley, with larger end houses once kept for supervisors. Whitelands Terraces even rise to three storeys.
Most of the older town is built of local white lias limestone laid in lime mortar, with coursed stone on the fronts and rougher rubble on the sides and backs. The roofs fall into two groups. The oldest cottages and outbuildings have orangey-brown clay pantiles, made locally before the railways came. Once the railways arrived, grey Welsh slate became affordable and went onto most of the mid and late Victorian terraces. Brick is rare in the older town and mostly appears on twentieth-century buildings, such as the pithead baths at Ludlows. Then there is the newer layer of twentieth-century and recent homes, including the built-up area that now spreads into Westfield, many of them under concrete tiles.
Steep streets, shared roofs and wet valley weather
Radstock sits in a steep-sided valley, so terraces step up and down the hillside and roofs meet one another at awkward heights. Rain runs down the slopes and finds any weakness where a roof meets a retaining wall or the next house up. On a terrace, one roof often runs straight across several homes, which means a slipped slate or a failed valley next door can show up as a damp patch in your bedroom. Victorian slate roofs are now well past the age when their nails rust through, known in the trade as nail sickness. The first sign is usually a slate slipping down and lodging in the gutter, and when that happens on several slopes it is time to consider re-slating rather than patching. Stone chimney stacks, often shared between neighbouring cottages, also take a beating from frost and rain.
Planning, conservation and the council
Radstock is in Bath & North East Somerset, not Somerset Council, so it is B&NES that deals with planning, building control and listed building consent here. Radstock has had a conservation area since 1999. In late 2025 the council consulted on a new character appraisal and a possible boundary extension taking in places such as Haydon, Clandown and Writhlington, so check the current boundary with the council's conservation team before planning changes to roof materials, rooflights or chimneys. Listed buildings include the Grade II Market Hall of 1897, now Radstock Museum, and the parish church of St Nicholas. Owners of listed homes will normally need consent for most roof changes, and Historic England's online list will tell you whether yours is one.
The council's draft appraisal is worth a read even if you are just outside the boundary. It notes that many older buildings keep their stone chimney stacks and that roof ridges generally run parallel to the road, both part of what makes the town look the way it does. It also warns that repointing in the wrong mortar has damaged some stone walls, which is why we use lime on old lias stonework.
What Radstock homeowners ask us to do
Many calls come from owners of slate terraces where slates keep slipping. Sometimes replacing broken and slipped slates is enough. Other times the battens and nails have failed across the whole slope, and we will show you photos so you can see the difference. Shared stacks need regular care, and rebuilding and repointing chimneys in lime is common work here, along with fresh lead flashings. On pantile cottages, cracked or loose ridges let water straight into the loft, and re-bedding or dry-fixing ridge tiles sorts that out.
The rear extensions and outshots behind many terraces often have flat roofs that have started to leak, especially old felt that has blistered and split. And because the terraces went up long before anyone insulated a loft, we are often asked about topping up loft insulation. The recommended depth for mineral wool is 270 mm, and we add ventilation where it is needed so the roof does not sweat.
Booking a roofer in Radstock
Call 07933 861 087 or send us a message for a free quote. Booking a visit is free, and we do not charge any call-out fee. We go up, photograph what we find and talk you through it, then put a written quote in your hands. On a terrace we tell you if the job touches a neighbour's roof, so you can speak to them first. Once the work is finished we clear the site and cart the old slates, battens and rubbish away.
Where we work in and around Radstock
