Westbury-on-Trym sits at the top end of Bristol's residential market — large detached and semi-detached properties, significant plot sizes, and a housing stock that ranges from genuinely grand Edwardian villas around the village centre to solid interwar detached houses and 1950s properties further from the core.
The roofs on these properties are not simple. A large Edwardian detached on Westbury Road will typically have multiple chimney stacks, complex hip and valley junctions, natural slate across a substantial roof area, and lead valleys that in some cases are approaching or past their design life. Getting the specification wrong on a roof of this scale and value is an expensive mistake.
We also see a higher proportion of properties in BS9 where homeowners have received quotes that don't reflect the correct material specification — cheaper Spanish slate quoted where Welsh should be used, or modern cement mortar proposed for period chimney repointing where lime is the only appropriate choice. On properties of this value, the wrong material decision affects both the building's long-term health and its presentation.
At TD Roofing we carry natural Welsh slate, work in lime mortar on all period chimneys, and use 4K drone surveys to map every element of the roof before we quote. On large BS9 properties that thoroughness isn't optional — it's the only way to produce an accurate, honest quote.

From the substantial Edwardian detached properties along Westbury Road and Fallodon Way — with their natural Welsh slate, multiple chimney stacks, and complex hip and valley configurations — to the large 1930s and post-war semis spread across the quieter streets around Trym Road and Passage Road, Westbury-on-Trym's roofscape is varied, high value, and demands a roofer with the right experience to handle it correctly.
From storm damage across the Cotswold fringes to minor leaks in Bedminster, our rapid-response team is equipped to handle structural emergencies. We provide temporary weathering to stop internal damage before performing a permanent, master-grade repair for any Bristol property.
Stop the cycle of leaking felt roofs. We install Firestone EPDM Rubber and GRP Fiberglass systems across Bristol. These are seamless, cold-applied membranes that are 100% UV resistant and ideal for modern South West extensions, orangeries, and garage conversions.
The chimney is the most common failure point on a Bristol roof. We provide specialized lime mortar repointing, chimney capping, and Code 4/5 lead flashing. Our leadwork isn't just functional; it’s finished to a standard that enhances the character and value of your property.
The ultimate investment in your home’s future. We specialize in full-scale re-roofs using premium clay tiles and natural slate. Our process includes a full timber inspection and the installation of breathable membranes to prevent the "sweating" and dampness common in older Bristol properties.
Bristol’s architectural heritage is built on slate. We are experts in sourcing Welsh and Spanish slate that satisfies conservation area requirements (particularly in Clifton, Redland, and Montpelier). Our slating is hand-dressed and fixed with copper nails to ensure it lasts for the next century.
We perform full replacements using high-grade, maintenance-free uPVC systems designed to withstand the South West’s damp, coastal climate. Our engineered installations include integrated ventilation to prevent loft condensation and eaves protection to stop pest ingress in your roofline.
In a city that faces heavy Atlantic weather systems, your guttering is your home's first line of defense. We don't just clear gutters; we engineer drainage solutions. We specialize in high-capacity uPVC, seamless aluminium, and traditional cast iron systems for period homes.
Natural light is a staple of Bristol’s high-end loft conversions, but a leaking skylight can quickly ruin your interior. As specialists in Velux® window maintenance and installation, we handle everything from seal replacements to full structural glazing upgrades and leak detection.
Beyond residential excellence, TD Roofing Contractors provides industrial-grade solutions for Bristol’s commercial sector. From industrial units in Avonmouth to retail premises in Temple Meads, we provide minimal-disruption roofing services tailored to your business's operational needs.
20 Years on Bristol's Highest-Value Period Properties Thomas Doherty has spent over 20 years working on Bristol's period housing stock — including the larger, more complex properties that dominate BS9. Multiple chimney stacks, extensive leadwork, natural slate across substantial roof areas — this is the work he knows best.
Free 4K Drone Survey on Every Quote On a large Westbury-on-Trym property a thorough survey isn't a courtesy — it's essential for an accurate quote. Our drone maps every roof element in high definition before a single figure is committed to paper. You see exactly what's there before you spend a penny.
Natural Welsh Slate and Lime Mortar as Standard We don't downgrade materials to sharpen a quote on high-value properties. Reclaimed Welsh slate, lime mortar on period chimneys, Code 5 lead on valley gutters and flashings — specified correctly every time.
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 meets 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 on the city's most demanding period properties.
Thomas is hands-on on every job regardless of scale. A large Edwardian re-roof in Westbury-on-Trym gets the same personal attention as a chimney repair in Redland. No call centres, no strangers dispatched while he's elsewhere — a small, experienced team with consistent standards on every property.
Fully vetted on Checkatrade — every review independently verified and unfiltered.
Yes, as standard. Our drone survey covers every stack on the property regardless of which one the homeowner is aware of. It's very common in BS9 to find secondary stacks with significant deterioration that hasn't yet shown up internally.
Code 4 lead has a lifespan of roughly 60 years. Code 5 — the correct specification for valley gutters — typically lasts 80 to 100 years. On Edwardian properties, much of the original leadwork is now at or approaching end of life. We assess the thickness and condition of all lead during the drone survey.
In most cases yes. We carry reclaimed Welsh slate and can source specific thicknesses and sizes. Where reclaimed Welsh isn't available in the required quantity, we'll discuss natural alternative slates — always transparently and with visual comparisons before you commit.
Yes. We provide full photographic and drone footage reports of storm damage on request — useful for insurance purposes and for documenting the condition of the roof before and after repairs.
Yes — Westbury-on-Trym, Henleaze, Stoke Bishop, Sneyd Park, and surrounding streets all fall within our core Bristol service area.
Yes. Call 0117 370 9986 for same-day emergency response across BS9.
Failing Lead Valleys on Large Edwardian Roofs The complex hip and valley configurations on Westbury-on-Trym's larger Edwardian properties mean extensive leadwork — valley gutters, soakers behind chimney stacks, and step flashings across multiple roof junctions. Original Victorian and Edwardian lead has a lifespan of roughly 60 to 100 years depending on thickness and exposure. On many BS9 properties it is now at or approaching end of life — cracking, developing pinholes, and lifting at dressed edges. When lead valley failures occur on a large roof, water can track through multiple roof areas before becoming visible inside. Our drone survey maps every lead junction before we quote.
Nail Sickness Across Substantial Roof Areas The scale of Westbury-on-Trym's larger properties means that nail sickness — when it takes hold — affects a much larger roof area than on a standard Victorian terrace. A full re-roof on a substantial BS9 Edwardian detached is a significant project requiring careful planning, correct scaffold design, and accurate material specification. We survey every affected property fully before quoting and are straight about whether partial re-fixing or full replacement is the more cost-effective solution.
Incorrect Material Specifications from Previous Contractors We see this consistently on BS9 properties — previous roofing work carried out in the wrong materials. Spanish or Chinese slate used to patch Welsh rooflines, hard cement mortar on period chimney stacks, modern torch-on felt on a section of roof immediately adjacent to original leadwork. These errors may look acceptable initially but cause progressive damage over time and affect the property's visual consistency and value. We identify all previous incorrect repairs during the drone survey and flag them clearly in the quote.
Multiple Chimney Stack Maintenance Large Westbury-on-Trym properties frequently have three or four chimney stacks — each requiring independent inspection, repointing, flaunching maintenance, and lead flashing assessment. It's common for one stack to have been repaired recently while others on the same property remain untouched for decades. Our drone survey covers every stack on the property as standard, not just the one the homeowner is aware of.
Ageing Flat Roof Sections on Extensions and Garages Even on high-value BS9 properties, the flat-roofed garage or rear extension is often the most neglected roof element — covered in ageing felt that hasn't been touched since the extension was built. We install EPDM rubber as our preferred flat roof system on Westbury-on-Trym properties — it's the most durable modern flat roofing membrane available and carries a 20-year material warranty.
