Our Services
Comprehensive roofing and building services for residential and commercial properties across London.
Pitched Roof Repairs
Our experienced roofers specialise in all aspects of pitched roof repairs across London. Whether you have slipped or broken clay tiles, cracked concrete tiles, damaged slate, or dislodged ridge tiles, we provide fast, reliable repairs that protect your home from water ingress. We work on all types of traditional UK pitched roofs including Victorian terraces, Edwardian semis, and modern builds. Our services include valley repairs, verge repointing, tile replacement, and emergency leak repairs. Every job is completed using high-quality materials that match your existing roof, ensuring a seamless finish.
Flat Roof Repairs & Replacement
Flat roofs are extremely common across London properties, particularly on rear extensions, dormers, garages, and bay window tops. Our team handles all flat roof repairs and full replacements using modern materials including torch-on felt, EPDM rubber membrane, and GRP fibreglass. We diagnose and fix ponding water issues, blistering felt, cracked joints, and failed flashings. When a repair isn't cost-effective, we provide complete flat roof replacements with a minimum 20-year guarantee. All our flat roof work meets current Building Regulations.
New Roof Installation
Whether you're building a new home, commercial premises, or adding a major extension, Actco Roofing & Building delivers complete new roof installations to the highest standards. We work with all roofing materials including natural slate, clay and concrete tiles, and flat roofing systems. Our installations include full timber work, breathable membrane, battening, tile or slate fixing, ridge and hip work, leadwork, and all associated flashings. We handle the entire process from structural design through to completion, ensuring full compliance with London Building Control.
Re-Roofing (Strip & Replace)
When your existing roof has reached the end of its life, a full strip and re-roof is the most effective solution. Our re-roofing service involves stripping the old tiles or slates, inspecting and replacing any damaged battens, felt, or timbers, and installing a brand-new roof covering. This is common on older London properties where the original roof may be 50+ years old. We salvage and reuse tiles where possible to maintain the character of period properties, or install new materials for a fresh, long-lasting finish. All work includes new breathable membrane and meets current insulation standards.
Chimney Repairs & Repointing
London's period homes are renowned for their chimney stacks, but decades of exposure to the elements takes its toll. Our chimney repair service covers full chimney stack rebuilds, repointing of deteriorating mortar joints, flaunching replacement (the cement cap around chimney pots), lead flashing renewal where the chimney meets the roof, and chimney pot replacement or capping for disused flues. We use lime mortar on listed and heritage properties where required. Our team works safely at height with full scaffolding or cherry-picker access as needed.
Fascias, Soffits & Guttering
Worn, rotten, or damaged fascias and soffits not only look unsightly but can allow water penetration and pest entry into your roof space. We replace old timber fascia boards and soffits with maintenance-free UPVC in a range of colours and styles. Our service includes removal of old materials, checking rafter feet for rot, installing new UPVC fascias and soffits, and fitting new seamless guttering and downpipes. We work with all major UPVC brands and offer a range of profiles to suit your property, whether it's a modern build or a traditional London terrace.
Lead Work & Flashing
Lead work is one of the oldest and most reliable waterproofing methods in UK roofing, and our skilled craftsmen are experts in traditional lead sheet work. We carry out all types of lead flashing repairs and installations including chimney step flashings, back gutters, front aprons, dormer cheeks, skylight surrounds, and valley linings. We use code 4 and code 5 lead sheet to BS EN 12588 standards. Whether it's a small flashing repair or a complete lead flat roof, our lead work is dressed, bossed, and welted to the highest traditional standards.
EPDM Rubber Roofing
EPDM (Ethylene Propylene Diene Monomer) rubber roofing is one of the most popular modern flat roofing solutions, offering exceptional durability and a lifespan of 25-50 years. Actco Roofing & Building are approved installers of leading EPDM systems including Firestone RubberCover and ClassicBond. The single-sheet membrane is laid in one piece, eliminating joints and seams that can fail over time. EPDM is ideal for London flat roofs on extensions, garages, dormers, and commercial buildings. It's UV-resistant, flexible in extreme temperatures, and virtually maintenance-free.
GRP Fibreglass Roofing
GRP (Glass Reinforced Polyester) fibreglass roofing provides a completely seamless, watertight finish that's ideal for flat roofs. The system involves laying fibreglass matting and resin over a timber deck to create a single monolithic surface with no joins or weak points. It's available in a range of colours and can include a non-slip finish for balconies and walkways. GRP is perfect for London rear extensions, garage roofs, bay tops, and dormer cheeks. With a life expectancy of 30+ years, it's one of the most durable flat roofing solutions available. All our GRP installations carry a manufacturer-backed guarantee.
Roof Inspections & Surveys
Regular roof inspections are essential for identifying potential problems before they become costly repairs. Our comprehensive roof survey service includes a thorough visual inspection of all roof coverings, flashings, chimneys, guttering, and roof timbers. We provide detailed written reports with photographs, highlighting any issues and recommending remedial work with estimated costs. Our surveys are ideal for homebuyers, landlords, property managers, and anyone concerned about the condition of their roof. We also offer drone-assisted surveys for hard-to-reach or dangerous roofs, providing high-resolution imagery without the need for scaffolding.
Emergency Roof Repairs
When storm damage, fallen trees, or sudden leaks threaten your property, Actco Roofing & Building provides a rapid 24/7 emergency response across Greater London. Our emergency team can be on-site within hours to make your roof safe and watertight. We carry out temporary weatherproofing with heavy-duty tarpaulins and emergency felt, board up damaged areas, and remove dangerous loose materials. Once the immediate danger is dealt with, we provide a full assessment and quotation for permanent repairs. We work with all major insurance companies and can assist with your claim documentation.
Loft Conversions
A loft conversion is one of the most cost-effective ways to add valuable living space to your London home. Actco Roofing & Building handles all types of loft conversions including rear dormers, side dormers, L-shaped dormers, hip-to-gable conversions, and Velux/roof window conversions. Our full service covers structural design, party wall agreements, Building Control applications, steel work, floor strengthening, staircase installation, dormer construction, roofing, insulation, plastering, electrics, plumbing, and final decoration. Most London loft conversions fall under Permitted Development, meaning no planning permission is needed.
Extensions & Building Works
Beyond roofing, Actco Roofing & Building offers comprehensive building services including single and double storey extensions, garage conversions, internal structural alterations, underpinning, and general building works. Our experienced team manages projects from initial design and planning applications through to completion and sign-off. We work closely with architects and structural engineers to deliver extensions that seamlessly integrate with your existing property. Whether you need a new kitchen extension, an additional bedroom, or a complete ground-floor remodel, we deliver quality construction that meets all Building Regulations.
