Totterdown sits on one of Bristol's steepest hillsides — rising sharply from the Bath Road up toward Wells Road and beyond, with tightly packed Victorian terraces running across the contours in long colourful rows. The area became famous for its painted facades, but what matters from a roofing perspective is what's happening above them.
These are Victorian roofs on steep slopes, often with complex internal valley configurations — the M-shaped or butterfly roof design that was common on this style of back-to-back terrace. Butterfly valleys collect debris, retain moisture, and require specialist knowledge and the right materials to maintain correctly. They are one of the most common sources of persistent, difficult-to-trace leaks on BS4 properties.
Add to that the exposed elevation — Totterdown's hillside position means roofs here catch south-westerly Severn Estuary weather head-on — and you have an area where roofing problems develop faster and more aggressively than in more sheltered parts of the city.
At TD Roofing, butterfly roofs are familiar territory. We use 4K drone surveys to map every valley, every lead junction, and every chimney stack before we quote. Nothing gets missed and nothing gets guessed at.
From the original Welsh slate on Georgian townhouses along Clifton Down Road to the flat-roofed extensions tucked behind Victorian semis on Pembroke Road — every roof in BS8 has its own demands. We know the area, the architecture, and exactly what each property type needs.
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 Most Demanding Victorian Roofs
Thomas Doherty has been working on Bristol's Victorian terraces for over 20 years — including the steep hillside properties and butterfly roof configurations that are unique to south Bristol. This is not generic roofing experience applied cautiously to a difficult roof type. It's familiarity built over two decades of working on exactly these properties.
Free 4K Drone Survey on Every Quote
On a Totterdown butterfly roof, a drone survey isn't just useful — it's the only way to properly assess the valley condition, the chimney stack, and the full roof elevation without putting someone on a steep pitch before you even know what you're dealing with. Every quote starts with a full aerial inspection.
Butterfly Roof Specialists
We understand internal valley configurations, the correct lining materials for different pitch and debris-load scenarios, and how to trace butterfly valley leaks accurately before committing to a repair location. This is specialist knowledge that not every Bristol roofer has.

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 the city's most characterful and demanding neighbourhoods.
Totterdown is the kind of area Thomas knows well — tight plots, steep pitches, complex valley configurations, and properties where cutting corners on access or materials creates problems fast. He's on every job personally. No call centres, no unknown subcontractors.
Fully vetted on Checkatrade — every review independently verified and unfiltered.
A butterfly or M-shaped roof has two slopes that fall inward toward an internal valley gutter rather than outward toward the eaves. This valley collects all the rainfall from both roof slopes in a single channel. When the valley lining fails or blocks with debris, water has nowhere to go except through the roof structure. Totterdown has a high concentration of this roof type on its Victorian terrace stock.
Very possibly yes. Butterfly valley leaks are notoriously difficult to trace because water enters at the valley and travels along roof timbers before dripping through a ceiling — often several metres from the actual failure point. A drone survey of the valley from above is the most reliable first step in accurate diagnosis.
Slipping slates on a steep roof above a public street or pavement are a safety issue and should be addressed promptly. We treat steep-pitch slate loss in Totterdown as a priority — both for the property and for the safety of people below.

H2: The Most Common Roofing Problems We Find in Totterdown
Butterfly Roof Valley Failures
Totterdown's butterfly valleys run the full length of each property — collecting every drop of rain from both roof slopes in a single internal channel. When the lead or felt lining fails, water backs up and tracks through the roof structure before appearing on a ceiling, often several rooms away from the actual failure point. A drone survey is the only reliable way to map the valley condition and pinpoint the leak before committing to a repair location.
Debris Accumulation in Internal Valleys
Even when the valley lining is intact, Totterdown's butterfly valleys collect leaves, moss, and wind-blown debris faster than any standard roof. A blocked valley during heavy rainfall backs water up above the lining height and forces it through the structure. Annual clearance is the most cost-effective maintenance a Totterdown homeowner can carry out.
Nail Sickness on Steep-Pitched Slate
On Totterdown's steep Victorian pitches — many at 45 degrees or above — nail sickness doesn't cause slates to slip gradually. They slide off cleanly and at speed, creating an immediate safety risk on a busy hillside street. We treat steep-pitch slate loss here as a priority.
Chimney Stack Deterioration
Totterdown's elevated position exposes chimney stacks to prevailing south-westerly winds without the shelter of surrounding buildings. Failed flaunching, cracked pots, and lifted lead flashing develop faster here than on equivalent roofs in more sheltered parts of the city.
