Expert New Roof Installations in London and Westminster

We pride ourselves on a methodical, customer-first approach that removes the stress from major home improvements. Our proven process ensures absolute precision from day one.1. Comprehensive Drone Survey: Before any scaffolding goes up, we conduct state-of-the-art drone roof inspections. This allows us to safely and accurately assess the condition of your existing roof, identifying hidden structural issues without causing any initial disruption to your property.2. Safe Stripping and Structural Assessment: Once the project begins, our team carefully strips away the old felt, battens, and tiles. We then perform a thorough inspection of the exposed timber trusses and joists to ensure the framework is sound.3. Weatherproofing and Battening: We lay down industry-leading breathable membranes to prevent condensation buildup, followed by treated timber battens installed to strict spacing guidelines.4. Precision Installation and Finishing: Your chosen materials are expertly laid. We utilise modern dry-ridge and dry-verge systems wherever possible, replacing outdated mortar methods with mechanically fixed solutions that withstand high winds and severe weather. Finally, all leadwork and flashing are meticulously dressed to guarantee a watertight seal.

Because London's housing stock is incredibly diverse, we supply and install a wide range of premium materials to suit both period properties and contemporary builds. For pitched roof installations, we frequently work with heritage-approved natural slate and traditional clay tiles from trusted manufacturers like Marley and Redland. These materials perfectly complement the historic character of Westminster's conservation areas while delivering exceptional durability.For extensions, garages, and modern flat roof replacements, traditional felt is no longer the only option. We specialise in high-performance GRP fibreglass roofing and EPDM rubber roofing. These seamless, flexible systems are highly resistant to UV damage, blistering, and tearing, making them the ultimate long-term choice for flat surfaces. Whatever the architectural style of your home, our roofing contractors will guide you toward the most reliable and aesthetically pleasing material.
