Roof repairs cover everything from replacing a handful of slipped tiles to fixing persistent leaks, re-pointing ridge tiles, repairing lead flashings, and addressing storm damage. The key difference between a repair and a replacement is scope — repairs target specific problem areas while the rest of the roof remains sound. You need a roof repair when you notice water stains on ceilings, damp patches on walls, missing or cracked tiles visible from ground level, or debris in your gutters that shouldn't be there. These are all signs that your roof's weather barrier has been compromised. At AC Roofing & Carpentry Ltd, we carry out targeted repairs that address the root cause — not just the visible symptom. We've seen too many properties where previous roofers patched the obvious leak without checking why it was leaking in the first place. A slipped tile might be a simple fix, but it might also indicate failing battens or a ventilation problem that needs addressing. We cover all of North London including Islington, Hackney, Camden, Finsbury Park, and Hampstead. Most repair jobs are completed in a single day with no scaffolding required.

Temporary patches — sealant over a crack, a cement fillet over a failed flashing — might stop the drip for a few weeks. But the underlying problem remains, and water always finds its way back. Every day a leak goes unaddressed, water is working its way into your roof structure. Timber battens soften, rafters begin to rot, and insulation becomes waterlogged and useless. What starts as a £300 repair can escalate into a £3,000+ structural job within a single winter. Damp from roof leaks also creates ideal conditions for black mould, which is a serious health hazard — particularly for children, elderly residents, and anyone with respiratory conditions. Mould remediation adds yet another cost on top of the roof repair itself. The most common mistake homeowners make is waiting to see if a leak 'gets worse' before calling a roofer. By definition, leaks only get worse. Water damage is cumulative and irreversible. The earlier you act, the less it costs and the more of your roof structure you preserve. How We Work ## Our Roof Repair Process 1 ### Inspection We inspect the roof from ground level and up-close to identify every problem area. 2 ### Diagnosis We determine the root cause — not just the symptom — and explain it clearly. 3 ### Fixed-Price Quote You receive a clear, itemised quote before any work begins. No surprises. 4 ### Repair Execution We carry out the repair using the correct materials and methods for a lasting fix. 5 ### Verification & Guarantee We check the repair holds, clean up completely, and issue your guarantee. Why It Matters ## Why Our Repairs Last ### Root Cause Fix We address why the problem happened, not just the visible damage. ### Same-Day Service Most repairs completed in a single visit — no waiting around for weeks. ### No Scaffolding Needed Many repairs can be done with ladders and harness, saving you time and money. ### Matching Materials We source matching tiles and slates so repairs blend seamlessly with your existing roof. ### Transparent Pricing Fixed-price quotes with no hidden call-out fees or material mark-ups. ### Guaranteed Work Every repair is backed by a written guarantee for your complete peace of mind. ## Roof Repairs: Common Issues and Expert Solutions ### Slipped, Cracked, and Missing Tiles Tiles can slip due to nail fatigue (nails rusting through over decades), broken nibs, or battens that have softened with age. A few slipped tiles are a straightforward fix — we refix or replace them and check adjacent tiles for the same issue. Cracked tiles are typically caused by frost damage or impact (falling branches, aerial work). We carry stock of common tile types including Marley Modern, Redland 49, and various plain tile profiles. For older properties with discontinued tiles, we source reclaimed stock or recommend the closest available match. ### Lead Flashing Failures Lead flashings seal the joints where your roof meets walls, chimneys, dormers, and other structures. Over time, lead can crack (fatigue cracking from thermal expansion), lift away from the wall, or have its mortar pointing wash out. Failed flashings are one of the most common causes of roof leaks in London properties. We replace worn flashings with new code 4 or code 5 lead, properly stepped and wedged into raked-out mortar joints, and pointed with a flexible sealant that moves with the lead. ### Ridge and Hip Tile Repairs Ridge tiles sit along the apex of your roof and hip tiles run along the angled edges. These are traditionally bedded in cement mortar, which degrades over decades and eventually crumbles, leaving ridge tiles loose or missing. We re-bed ridge tiles using a modern dry ridge system (mechanical fixing with clips and a ventilated roll) where possible, which eliminates the mortar problem entirely and provides reliable ventilation. For heritage properties where a traditional mortar bed is preferred, we use a flexible, frost-resistant mortar. ### Valley and Gutter Repairs Valleys — the V-shaped channels where two roof slopes meet — are high-flow areas that take a disproportionate amount of water. Lead-lined valleys can last 80+ years, but GRP and mortar valleys are more prone to cracking and failure. We repair or replace valley linings using lead sheet or GRP troughs depending on the roof type. Gutters are closely related — blocked or broken gutters cause water to back up under the eaves, rotting fascia boards and soffit timbers. We repair, reseal, or replace guttering as part of any comprehensive roof repair. ### Chimney Stack Repairs Chimney stacks are exposed to severe weather on all sides and are a common source of water ingress. Issues include cracked render, failed flaunching (the mortar cap), loose pots, and deteriorated pointing. We carry out chimney re-pointing, re-flaunching, lead flashing replacement, and stack rebuilds where necessary. If a chimney is no longer in use, we can cap it with a ventilated cowl to prevent rainwater entry while maintaining airflow to avoid condensation.
