London's roofline is rarely just one thing — a Victorian pitched roof with a flat-roofed rear extension bolted on later, meeting at a junction that's usually where the actual problems start. Roofing work here means understanding both roof types and how they interact, not just one or the other.

Pitched & Flat Roofing
Pitched Roofs
Pitched roofs — the sloped tile or slate roofs on most traditional London terraces and semis — fail gradually rather than suddenly: a slipped or cracked tile here, a ridge tile working loose there, none of it dramatic until a period of heavy rain finds the gap. Repairs are usually localised — replacing specific tiles or slates, resecuring a ridge line — rather than a full re-roof, which is only necessary once the underlying felt or battens have failed more broadly, not just the visible tiles.
Slate roofs common on older London properties need slate-specific repair rather than a generic tile fix — matching slate size, thickness and fixing method to what's already there, since mismatched repairs are often more visible and more likely to fail again than the original problem.
Flat Roofs
Flat roofs are common on London extensions and rear additions, and modern materials — EPDM rubber, GRP fibreglass — have largely replaced traditional felt, lasting considerably longer and handling London's weather better than the felt roofs of a few decades ago. A flat roof isn't actually flat; it needs a slight fall built in to drain properly, and a roof that's ponding water rather than shedding it is usually a sign the fall wasn't built correctly in the first place, not a material failure.
The junction where a flat roof meets a pitched one — extremely common in London, where a single-storey rear extension's flat roof meets the original pitched roof above — is the single most common place a leak actually starts, since it's where two different roofing systems and two sets of flashing have to work together perfectly.
Not sure what's wrong?
What the Symptoms Usually Mean
| Symptom | Likely Cause | Urgency |
|---|---|---|
| Damp patch on ceiling | Slipped tile, cracked slate, or failed flashing | Book a repair soon — worsens with more rain |
| Sagging roofline | Structural timber issue beneath the covering | Urgent — needs inspection promptly |
| Missing tiles after a storm | Wind damage | Urgent if the property's now exposed |
| Water pooling on a flat roof | Incorrect fall or blocked outlet | Book a repair — shortens roof lifespan if left |
| Green algae or moss | Normal weathering, not usually a failure | Not urgent — general maintenance |
| Blocked or overflowing gutter | Debris build-up or a damaged section | Book before it causes damp elsewhere |
Guttering & Fascias
Guttering doesn't get much attention until it fails, but a blocked or damaged gutter redirects water somewhere it shouldn't go — typically down an external wall, which over time causes damp problems that get blamed on the wall rather than the gutter actually responsible. Fascias and soffits, the boards along the roofline that guttering attaches to, need to be sound for the gutter itself to be properly supported, which is why gutter repairs sometimes reveal fascia problems that weren't visible from the ground until the guttering came off.
Emergency Roof Repairs
Storm damage, a sudden leak, tiles coming loose in high wind — roofing emergencies get treated with the same priority as any other urgent trade call-out, since an exposed roof causes rapidly compounding damage the longer it's left. A temporary weatherproof cover is often the first step on an emergency call-out, stopping further water ingress immediately, with the permanent repair scheduled properly once the immediate risk is contained.
Roof Access & Working Safely on London Properties
Terraced and semi-detached London properties often mean roof access is more constrained than it looks from the ground — a shared party wall, limited space for scaffolding on a narrow street, or a rear extension roof that needs its own separate access point from the main roof above it. Getting access sorted properly before work starts, rather than improvising it on the day, is what keeps a roofing job on schedule rather than losing time to logistics that should have been planned in advance.
Two roof types, one team that understands how they meet — which matters more in London than almost anywhere else, given how much of the city's housing stock is exactly this combination: an original pitched roof with a later flat-roofed addition. The junction between them isn't a footnote; it's usually the actual answer to where a leak's coming from, and it's the detail that gets missed when two separate specialists handle the pitched and flat sections independently rather than as one connected roof.
Frequently asked
Questions Before You Get In Touch
How do I know if I need a roof repair or a full re-roof?
Localised damage — a handful of slipped tiles, a section of failed flashing — is usually repairable. A full re-roof becomes necessary when the underlying structure, felt or battens have failed broadly, which a roof inspection can confirm rather than guessing from visible symptoms alone.
How much does roof repair cost in London?
Cost depends heavily on the type and extent of the damage — a handful of slipped tiles costs far less than repairing a failed flat roof junction. A written, itemised quote follows a free visit.
Do you repair both pitched and flat roofs?
Yes — and specifically the junction where the two meet, which is one of the most common places a London property's roof actually leaks.
How urgent is a roof leak?
More urgent than it might feel in the moment — a small leak compounds quickly, especially with more rain forecast, and can affect insulation, ceilings and electrics the longer it's left. Booking a repair promptly is considerably cheaper than repairing the secondary damage later.
Can you fit a temporary fix before a full repair?
Yes, for anything urgent — a temporary weatherproof cover stops further water ingress immediately, with the permanent repair scheduled once the immediate risk is contained.
Do you clear and repair guttering as well as roofing?
Yes — guttering, fascias and soffits are part of the same roofing service, since a failing gutter often causes damp problems that get mistakenly blamed on the wall or roof itself.
