Bishopston is predominantly Edwardian — built roughly between 1900 and 1914 in the wave of residential development that followed the expansion of the Gloucester Road tram route. The result is one of the most architecturally coherent neighbourhoods in north Bristol: generous bay-fronted semis, original Welsh slate roofs, decorative terracotta ridge tiles, and substantial chimney stacks on virtually every property.
These are beautiful roofs. They're also over 100 years old, and they accumulate very specific problems that a roofer without genuine period property experience will either miss or fix incorrectly.
The most damaging mistakes we see on Bishopston properties are cement repointing on Victorian and Edwardian chimney stacks — which accelerates brick spalling and traps moisture — and Spanish slate used to match original Welsh during repairs, which looks visually wrong and performs differently under Bristol's weather. On a Bishopston street where every roof is broadly consistent in appearance, these errors stand out and affect property values.
At TD Roofing we carry reclaimed Welsh slate, work exclusively in lime mortar on period chimneys, and start every quote with a free 4K drone survey. Nothing gets missed and nothing gets guessed at.
From the wide bay-fronted Edwardian semis lining Downend Road and Sommerville Road — with their original Welsh slate, decorative ridge tiles, and tall exposed chimney stacks — to the flat-roofed rear extensions added to properties along Ashley Down Road over the decades, Bishopston's roofscape is distinctive, demanding, and unforgiving of the wrong approach. TD Roofing Contractors know these streets and we know exactly what these properties need.
20 Years on Bristol's Edwardian Stock Thomas Doherty has been working on period properties across Bristol for over 20 years. Bishopston's Edwardian semis are familiar territory — the slate profiles, the chimney configurations, the bay roof details, the lime mortar requirements. This isn't general knowledge picked up on modern builds.
Free 4K Drone Survey on Every Quote Every quote starts with a full aerial inspection — ridge tiles, chimney stacks, valley junctions, bay roof sections, all visible in high definition before a penny is spent. No pavement guesswork.
Reclaimed Welsh Slate and Lime Mortar as Standard We don't substitute Spanish slate for Welsh on Bishopston's Edwardian rooflines without telling you. We carry reclaimed stock, work in lime mortar on every period chimney, and specify correctly rather than cheaply.
10-Year Workmanship Guarantee Every job is backed by a full 10-year workmanship guarantee. Fully insured, Checkatrade vetted, and no payment until the work is done to your satisfaction.
TD Roofing Contractors is run by Thomas Doherty — an Irish tradesman who came to Bristol over 20 years ago and built his reputation working across north Bristol's period housing stock one job at a time.
Thomas is hands-on on every job. No call centre, no strangers dispatched while he's elsewhere. A small, experienced team that brings the same standards to a ridge tile re-bed on Sommerville Road as to a full re-roof on Downend Road.
Fully vetted on Checkatrade — every review independently verified and unfiltered.
In most cases yes. We carry reclaimed Welsh slate and can source specific thicknesses and sizes for matching work on Bishopston properties. We won't substitute Spanish slate without discussing the visual and performance differences with you first.
It's commonly both on older Bishopston bay roofs. Failed lead flashing at the wall junction and deteriorated felt beneath the lead are frequently found together on properties of this age. The drone survey gives us a clear picture of the bay roof condition before we quote.
If individual ridge tiles are rocking, lifting, or visibly cracked, they need re-bedding on a fresh mortar bed. If the tiles themselves are sound but the mortar joints between them are open and crumbling, repointing is sufficient. We assess each ridge section individually during the drone survey.
Yes — Bishopston, Ashley Down, St Andrews, and the surrounding streets all fall within our core Bristol service area.

Nail Sickness on Edwardian Welsh Slate The wrought iron cut nails used to fix Welsh slate on Bishopston's Edwardian roofs are now well over 100 years old. When they corrode through, slates begin slipping — gradually at first, then more rapidly as neighbouring slates lose lateral support. The pattern we typically see on Bishopston roofs is a scattering of slipped slates concentrated on the south and west elevations, which bear the brunt of prevailing weather. Once nail sickness is confirmed across more than 20 to 30 percent of the roof area, a full re-roof on new battens with stainless fixings is the correct and most cost-effective course of action.
Cement Repointing on Edwardian Chimney Stacks This is the single most common damaging error we find across Bishopston's housing stock. A previous contractor — often decades ago — has repointed the chimney stack in hard Portland cement rather than lime mortar. The cement initially looks solid but is far too rigid for Edwardian brickwork. It cracks under thermal movement, traps moisture behind it, and causes the brick faces to spall and break down over time. We cut out the old cement entirely and repoint in the correct lime mortar specification — the only appropriate material for pre-1920 brickwork.
Failed Bay Roof Sections Bishopston's bay-fronted semis typically have a small flat or shallow-pitched roof section over the ground floor bay, often finished in lead or mineral felt. These sections are a persistent source of leaks — particularly where the bay roof meets the main wall and where the flashing has lifted or cracked. We see this on a significant proportion of Bishopston properties and it's often the source of damp that's been misdiagnosed as a wall issue.
Decorative Ridge Tile Failures The terracotta decorative ridge tiles on Bishopston's Edwardian roofline are a distinctive architectural feature — and a common source of water ingress when the mortar bed beneath them fails. Repointing or re-bedding ridge tiles in lime mortar is a relatively straightforward job that prevents significant water damage to the roof structure below. We see many Bishopston properties where loose or rocking ridge tiles have been left for years, allowing water to track down into the roof space unchecked.
Flat Roof Rear Extensions at End of Life The post-war decades saw many Bishopston semis gain flat-roofed rear kitchen extensions — most of them covered in torch-on felt that is now well past its usable life. Blistering, cracking, and pooling water on these roofs are signs the membrane needs replacing rather than patching. We install EPDM rubber as our preferred system — it carries a 20-year material warranty and handles Bristol's rainfall significantly better than ageing felt.
