Roof Tile Replacement London

What we cover

Pitched roof repair across London terraces, semis, mansion blocks and small commercial premises. Tile work, ridge work, flashings and chimney pointing — the everyday roof faults that cause a leak or a missing tile after a storm. Larger jobs (full re-roof, structural rafter work, flat roof replacement) are quoted separately under our general repairs service.

• Single and multiple slipped tile re-fix — clay, concrete and natural slate matched on site
• Ridge tile re-bed in 4:1 sand/cement or upgrade to mechanical dry ridge
• Lead flashing repair and replacement (code 4, code 5) to chimneys, abutments and parapets
• Chimney stack repointing with lime or cement mortar to match existing
• Valley re-line in code 4 lead or GRP fibreglass over rotten boards
• Leak trace — hose test, smoke test, attic inspection to locate the actual entry point
• Dry verge upgrade to stop cracking mortar bedding on gable ends
• Chimney bird guard, cowl and cap fitting alongside any repair visit
• Pointing repair around skylights, dormer cheeks and lean-to junctions
• Tower access for two-storey work where ground conditions allow — no scaffold cost on most jobs

Lead flashing and chimney work

The largest share of London roof leaks do not come from missing tiles — they come from the lead flashing around chimneys and abutments. London chimneys are still tall, still common, and the lead seal that runs between the brickwork and the tiles ages out long before the tiles themselves. A 30-year-old code 3 lead flashing on a south-facing chimney is at the end of its design life.

Repair is normally either re-dressing and re-pointing the existing lead where it has lifted, or stripping the failed flashing and re-lining with new code 4 or code 5 sheet. Soakers tucked under each individual tile course, a step flashing dressed over them, and a chase cut and pointed into the chimney brick — the classic detail done properly, not silicone-bedded onto the tiles like a budget cowboy job.

Chimney stack repointing is the partner job. Once the lead is right, the stack itself needs sound pointing above the flashing line or the same fault returns within 18 months. Lime mortar is used on listed and conservation-area buildings; 4:1 sand and cement on standard stock-brick chimneys. Bird guards, terracotta pots and clay rain caps can all be fitted on the same visit.

Leak trace before any tile is touched

Roof leaks rarely come from where the water shows up inside. Water tracks along the underside of the felt or sarking membrane, runs down a rafter, and drips onto a ceiling three metres from the actual fault. Ripping tiles off the visible damp spot wastes time and money.

Every leak job starts with a structured trace — attic inspection from inside, ground-level visual check, controlled hose test from the roof if needed. Only then are tiles lifted. On most London terraces the fault is one of four things: a slipped tile, a cracked ridge bedding, a perished flashing, or a blocked valley letting water back-up under the tiles. A photo report goes with every leak repair so the cause is documented for your records.

If internal damage has already happened — stained plaster, soft ceiling, swollen architrave — that is fixed alongside the roof under water damage restoration on the same visit where possible. One day on site, both trades.
