A new roof is the single most significant investment you can make in your property's structural integrity. It's needed when repairs are no longer cost-effective — typically when the existing roof has widespread damage, failing battens, deteriorated felt, or has simply reached the end of its natural lifespan. Most pitched roofs in London were built to last 50–80 years depending on the materials used. If your roof is approaching or past that age, or if you're seeing multiple simultaneous issues — missing tiles, sagging ridgelines, persistent leaks, or daylight visible from the loft — a full replacement is the right decision. At AC Roofing & Carpentry Ltd, we handle every aspect of new roof installations: from stripping the old roof and inspecting the timber structure, through to battening, felting, tiling, and finishing. We work with natural slate, concrete tiles, clay tiles, and flat roofing systems depending on your property's character and your budget. We serve homeowners, landlords, and developers across Islington, Hackney, Camden, and the wider North London area. Every new roof installation includes a detailed written specification, a fixed-price quote, and a workmanship guarantee.

Water finds its way through cracked tiles and degraded felt, soaking into rafters and purlins. Over time, this leads to timber rot that compromises the structural integrity of your entire roof. By the time most homeowners commit to a new roof, they've already spent thousands on emergency repairs and patch jobs that never held. Each repair buys a few months at best, while the underlying problems continue to worsen beneath the surface. There's also the hidden cost of heat loss. A roof with failing insulation and degraded felt can account for up to 30% of your total heat loss. That's a significant chunk of your energy bills going straight through the roof — literally. The worst-case scenario? A structural failure that requires not just a new roof, but extensive timber work to rebuild the frame beneath it. What could have been a £10,000 job becomes a £25,000+ project. Early action saves money, protects your home, and gives you certainty. How We Work ## How We Deliver Your New Roof 1 ### Roof Survey Full inspection of the existing roof structure, timbers, and overall condition. 2 ### Specification & Quote Detailed material specification and a fixed-price written quote with no hidden costs. 3 ### Strip & Inspect We remove the old roof covering and inspect every timber for rot or weakness. 4 ### Build & Install New felt, battens, and tiles are fitted with precision to building regulations. 5 ### Completion & Guarantee Final inspection, site clean-up, and your written guarantee handed over. Why It Matters ## What a New Roof Delivers ### Decades of Protection A properly installed new roof lasts 50–80 years with minimal maintenance. ### Energy Savings New breathable membranes and insulation cut heat loss by up to 30%. ### Increased Property Value A new roof adds £10,000–£20,000 in property value and removes buyer objections. ### Structural Confidence We inspect and replace any weakened timbers, so your roof frame is solid. ### Building Regs Compliant Full compliance with current building regulations including fire and thermal standards. ### Clean, Professional Finish Neat leadwork, straight ridge lines, and proper detail work that looks right. ## New Roof Installation: Materials, Methods & Specifications ### Natural Slate Roofing Natural slate is the premium choice for new roofs in London, especially on period and conservation-area properties. Welsh slate (Penrhyn, Cwt-y-Bugail) and Spanish slate are the most commonly specified. Slate roofs can last 100+ years and offer an unmatched aesthetic that complements Victorian and Edwardian architecture. We fix slates using copper nails on treated battens over a breathable membrane. Centre-nailing or head-nailing is chosen based on exposure and slate size. For heritage properties, we match existing slate sizes and laying patterns to maintain architectural integrity. ### Concrete and Clay Tiles Concrete interlocking tiles (Marley, Redland) are the workhorse of modern roofing — durable, cost-effective, and available in a range of profiles and colours. They typically last 50–60 years. Clay tiles (plain tiles, pantiles) offer superior aesthetics and longevity, with some handmade clay tiles lasting well over 100 years. We work with all major tile manufacturers and can match existing profiles for partial replacements or extensions. All tiling work includes mechanical fixing in accordance with BS 5534, which specifies nail and clip requirements based on wind zone and building height. ### Roof Timber and Structure A new roof isn't just about the tiles — the timber structure beneath is equally important. We inspect every rafter, purlin, ridge board, and wall plate for rot, woodworm, or structural movement. Any weakened timbers are replaced with treated softwood to the correct section size. If the roof structure needs significant work, we design and install new timber frames using traditional cut-roof techniques or modern trussed rafters depending on the property type. All structural timber work is carried out to Building Regulations Part A (Structure) and signed off by building control. ### Leadwork and Flashing Proper leadwork is what separates a roof that lasts from one that leaks within five years. We use code 4 and code 5 lead sheet for all flashings, valleys, and abutments — cut and dressed by hand on site. Lead is fitted with proper expansion joints (no continuous runs over 1.5m) and secured with lead wedges and pointed in with a flexible sealant. We also install lead soakers at side abutments and stepped flashings where the roof meets a wall. Poor leadwork is the number one cause of premature roof failure, which is why we never cut corners on this critical detail. ### Ventilation and Condensation Control Modern roofs must be ventilated to prevent condensation build-up in the roof space. Depending on the roof design, we install soffit vents, ridge vents, or tile vents to provide the required airflow. For warm roof constructions (insulation at rafter level), we use breathable roofing membranes that allow moisture vapour to escape while remaining waterproof. For cold roof constructions (insulation at ceiling level), cross-ventilation through soffit and ridge is essential. Getting ventilation wrong leads to condensation, timber rot, and mould — problems we've seen in countless London loft conversions where ventilation was an afterthought.
