Redland's housing stock is almost entirely Victorian — built between 1875 and 1910 in the wave of residential development that followed the expansion of north Bristol's tram network. The original roofing material across this stock is Welsh slate, fixed with wrought iron cut nails that are now 115 to 150 years old. When enough of those nails have corroded through — a condition known as nail sickness — individual slate replacement becomes a losing battle and full re-roofing is the correct decision.
When that point arrives, the replacement has to be done right. Redland's Victorian streetscapes are visually coherent — row after row of terraces in matching Welsh slate, with consistent ridge lines, chimney configurations, and roof pitches. A re-roof in concrete interlocking tile, fibre cement, or Spanish slate that doesn't match the surrounding rooflines visually damages the property and the street.
We specify reclaimed Welsh slate on every Redland Victorian re-roof where it's the original material — sourcing matched grades and thicknesses to maintain both the performance and the appearance of the roof. Every re-roof starts with a free 4K drone survey that maps the existing roof condition, assesses the underlying timber structure, and confirms the correct specification before we quote.
Reclaimed Welsh Slate Re-Roof
The correct choice for Redland's Victorian terraces. We source matched reclaimed Welsh slate, install on new treated timber battens with stainless steel fixings, and finish with Code 5 lead in all valleys and chimney junctions and a dry ridge system at the apex.
Natural Slate Re-Roof
Where reclaimed Welsh slate isn't available in sufficient volume for a specific job, we specify new natural slate — Spanish or Brazilian — in the closest available thickness and colour match. We discuss the options and any visual differences transparently before you commit.
Full Strip and Re-Batten
Every new roof we install in Redland starts with a complete strip — slate, underlay, and battens — down to the rafter. New breathable membrane and treated timber battens are installed before any slate goes on. We never reuse original battens on a Victorian roof — at 120 years old they are not worth reusing.
Structural Timber Assessment and Repair
Once the existing covering is stripped, the rafter ends, ridge board, and any timber in contact with flashings are exposed. On Redland's older properties, rot in rafter ends is common where flashings have been failing. We assess and repair all structural timber before the new covering goes on, with additional work agreed and documented before it begins.
Dry Ridge and Dry Verge Installation
We install dry ridge systems on all new roofs in Redland — mechanically fixed without mortar, carrying a 20+ year guarantee and significantly more durable in Bristol's freeze-thaw climate than traditional mortar bed ridge. Dry verge on gable ends prevents wind uplift and eliminates the open mortar joints that fail on exposed elevations.
A complete new roof quote on a Redland Victorian terrace should specify every element of the job. Here's what ours always includes:
If any element is missing from a quote you've received, ask why. The ones most commonly omitted to reduce a headline price are scaffold strike, valley lead specification, and chimney repointing.
This is the most important decision facing Redland homeowners with a Victorian slate roof and we want to be straight about how to make it.
Nail sickness — the corrosion of the original wrought iron cut nails holding Welsh slate in place — is endemic across BS6's Victorian housing stock. The nails have a natural lifespan of 80 to 100 years. Most of Redland's roofs are 115 to 150 years old. The maths is straightforward.
In the early stages of nail sickness, one or two slates slip per year, typically on the south and west elevations that bear the most weather. Replacing these individually is reasonable while the overall roof structure is sound.
The problem comes when the rate of slippage increases. Once slates are coming off consistently after every storm across multiple roof sections, individual replacement is no longer cost-effective — you are paying for repeated call-outs and individual slate costs while the underlying fixing system continues to fail. At this stage, a full re-roof on new battens with stainless steel fixings is cheaper over a five-year horizon than continued patching.
Our drone survey tells you clearly which situation you're in — early stage nail sickness with patching still viable, or advanced nail sickness where re-roofing is the honest recommendation. We will never recommend a full re-roof on a Redland terrace where targeted repairs would genuinely solve the problem.
Do I need reclaimed Welsh slate for my Redland Victorian terrace?
Not strictly required by planning law in most parts of Redland outside designated Conservation Areas — but strongly advisable for visual consistency with the surrounding streetscape. A concrete tile or Spanish slate re-roof on a Redland terrace looks visually inconsistent with the Welsh slate rooflines either side of it and can affect the property's value and appeal. We discuss the options honestly on every survey.
How long does a Victorian terrace re-roof take in Redland?
A standard two-bedroom Victorian terrace in reclaimed Welsh slate typically takes 6 to 10 working days including scaffold erection and strike. Larger properties and semis take longer. The property is weathertight at the end of every working day — we never leave a stripped roof unprotected overnight.
My terrace is mid-row — does that cause complications for scaffold?
On a mid-row Redland terrace, scaffold is erected on the front elevation and — where rear access allows — the back elevation. Where rear gardens are accessible, materials can be craned or passed through. We plan the access approach as part of the survey and include all associated logistics in the written quote.
What happens if structural timber rot is found once the roof is stripped?
We document all additional timber found to be rotten, photograph it, and agree any additional cost with you before carrying out repairs. We never proceed with unrequested structural work without your sign-off. Our initial quote includes a provisional timber repair allowance based on the drone survey's assessment of risk — so you have an idea of the potential range before work begins.
