Professional New Roof Installation London in London
Adding a new roof to your London property represents a significant investment. Whether you are extending your home in Chelsea, replacing an aging conservatory roof in Bromley, or constructing a garage in Richmond, the quality of your new roof installation determines how well it performs over decades. Choosing experienced roofing contractors for new roof installation in London protects your investment and ensures lasting performance.
KS Roof Master has been installing new roofs across Greater London for over twenty years. We understand the specific requirements of different roof types, from traditional pitched roofs with natural slate in Islington conservation areas to modern flat roof extensions in new developments throughout Croydon and Barking. Our teams bring specialist expertise to every new roof project, whether residential or commercial.
New roof installation in London differs significantly from repair work. Proper installation requires understanding of building regulations, thermal performance requirements, structural considerations, and appropriate detailing for each roof type. We approach every new installation as a complete system rather than simply attaching materials to a structure. Proper ventilation, insulation integration, and weatherproofing details all contribute to long-term performance.
For extensions and conservatories, we work alongside builders and architects to ensure roof integration with existing structures. For standalone structures like garages and outbuildings, we provide complete design and installation services. Every new roof we install comes with comprehensive guarantees covering both materials and workmanship.
Common New Roof Installation Scenarios in London
Different property types and projects require different approaches to new roof installation:
Extension Roofs
London homeowners continuously extend their properties, from single-storey rear extensions in Victorian terraces to double-storey additions in semi-detached properties. Extension roofs must integrate seamlessly with existing structures while meeting current building regulations for thermal performance. We install both flat and pitched extension roofs, handling all aspects from structural support to final weatherproofing and fascias.
Conservatory Roof Replacement
Many London conservatories suffer from excessive heat in summer and cold in winter due to inadequate original roofs. Replacing polycarbonate or poor-quality glass roofs with solid tiled or insulated alternatives transforms these spaces into usable year-round rooms. We install full replacements including structural modifications where necessary, handling everything from planning considerations to final decoration.
Garage and Outbuilding Roofs
Freestanding garages and garden buildings require robust roofing that withstands weather exposure without demanding maintenance. Flat roofs using EPDM or felt systems offer cost-effective solutions, while pitched roofs with tiles or shingles provide traditional aesthetics. We assess each structure and recommend the most appropriate system based on usage, appearance preferences, and budget.
New Build Roofs
Self-build projects and new constructions in London require careful specification and installation of complete roofing systems. We work with architects, self-builders, and developers to deliver pitched and flat roof systems that meet all current building regulations and provide long-term performance. From roof structure through to finished tiles or membrane, we provide complete installation.
Roof Conversions
Converting flat roofs to pitched or vice versa requires structural assessment and often planning permission in London. We handle feasibility assessments, structural calculations, and installation for roof conversions. Many properties in areas like Maida Vale and Notting Hill benefit from converting flat roof areas to pitched construction for both practical and aesthetic reasons.
Roof lanterns and Rooflights
Modern flat roof design increasingly incorporates daylight elements. We install roof lanterns, VELUX windows, and flat rooflights as part of new roof installations. Proper installation is crucial for weatherproofing around these penetrations, and we ensure all details are executed correctly to prevent leaks and maintain thermal performance.
Benefits of Professional New Roof Installation
New roof installation is not the time to cut corners. Professional installation provides lasting value:
Building Regulation Compliance
Current building regulations require specific thermal performance levels and structural standards for new roofs. We handle all building regulation requirements, including necessary notifications to local authorities and arranging inspections at appropriate stages. Your new roof will meet or exceed all current standards, ensuring compliance and optimal energy performance.
Proper Structural Design
Roofs must be structurally sound to withstand London weather, including wind loads and potential snow loading. We specify and install appropriate structural support, whether traditional timber roofing or modern insulated panel systems. Proper structural design prevents future problems like deflection, which causes membrane failure in flat roofs or tile slip in pitched roofs.
Correct Ventilation
Inadequate ventilation causes condensation, timber decay, and premature failure of roofing materials. We ensure all new roofs have appropriate ventilation provisions, whether through traditional vented eaves details for pitched roofs or modern insulated flat roof systems with integrated ventilation channels. Correct ventilation extends roof life significantly.
Quality Materials
We specify materials from established manufacturers with genuine warranty support. Whether using Redland or Sandtoft tiles, Kilma choice natural slate, Firestone EPDM, or Cromar GRP systems, our specifications prioritises long-term performance over initial cost savings. Quality materials perform better and last longer, providing better value over the roof lifespan.
Expert Workmanship
Our installation teams are trained specialists in their respective roof types. Pitched roof teams understand proper tiling, slate hanging, and flashing details. Flat roof specialists install membranes with correct seam preparation and detailing. Specialist expertise ensures your new roof is installed correctly the first time, avoiding the expensive problems that arise from poor installation.
Complete Service
From initial consultation through to final clean-up, we manage every aspect of your new roof installation. We coordinate with other trades where necessary, protect your property during work, and leave sites clean and tidy. Our project management ensures smooth delivery with minimal disruption to your household or business.

Frequently Asked New Roof Installation Questions
Honest answers about new roof installation in London.
Project duration varies significantly based on roof type and size. A small flat roof extension typically completes in two to three days. Larger or more complex roofs might take five to ten days. Full roof replacements involving structural work can extend to two weeks or more. We provide realistic timescales during the survey and quotation process, then work efficiently to meet agreed schedules. Weather can affect programmes, particularly for pitched roof work where tiles cannot be laid in heavy rain.
Planning permission is generally not required for new roofs on extensions that fall within permitted development limits. However, this depends on your property location, local planning restrictions, and whether your property is listed or in a conservation area. We can advise on planning requirements during our initial consultation. Building regulation approval is almost always required for new roofs due to thermal performance standards, and we handle this process as part of our service.
The choice depends on several factors. Pitched roofs often suit traditional London properties and can provide useful loft storage space. Flat roofs offer more flexibility for first-floor extensions and work well with modern property styles. We discuss your priorities regarding appearance, budget, usage of any roof space, and integration with existing architecture to recommend the most appropriate solution for your specific situation.
Yes, in most cases you can remain in your property during new roof installation. Ground floor extensions or garage roofs cause minimal disruption to household routines. We schedule work to minimise impact, protect your property throughout, and maintain clean and safe conditions. We will discuss any specific arrangements needed for your project during the planning stage.
All new roof installation work comes with a 10-year labour guarantee on workmanship. Material guarantees vary by system: flat roof membranes typically carry 15-25 year manufacturer warranties, while tiles and slates are covered for 30 years or more. Combined, your new roof has comprehensive guarantee protection backed by our established reputation.
Building regulation compliance is included as standard with our new roof installation service. We assess your project against current requirements, prepare and submit the necessary documentation to your local authority, arrange required inspections at appropriate stages, and issue completion certificates upon finished installation. This ensures your new roof legally complies with all applicable standards.
