East London’s diverse housing stock — from Victorian terraces to modern apartments — demands specialist mansard roofing expertise. Our team has spent 20+ years mastering every roof type found across the region. Whether you own a Victorian terrace in Hackney, a 1930s semi in Ilford, a Becontree Estate home in Barking, or a warehouse conversion in Shoreditch, we have the skills and materials for the job.
A mansard conversion replaces the rear slope of your roof with a near-vertical wall (typically 72°) topped with a flat roof section. This creates the maximum possible headroom and floor space — significantly more than a standard dormer. East London’s diverse housing stock includes Victorian terraces across Hackney, Bow, and Bethnal Green, Edwardian villas in Walthamstow and Leyton, 1930s semis stretching through Ilford and Romford, post-war estates in Barking and Dagenham, and modern apartments in Stratford and Canary Wharf. In East London, mansard conversions are particularly popular on Victorian and Edwardian terraces where the existing roof pitch and party wall heights allow full-height rooms across the entire footprint.
Mansard conversions usually require planning permission because they change the overall height and shape of the building. In East London, approval rates are generally high for rear mansards that do not overlook neighbouring properties. Front mansards are rarely approved. Conservation areas have stricter requirements. We work with experienced architects and can advise on the likelihood of approval before you invest in drawings and applications.
The near-vertical mansard wall is typically clad in natural slate (heritage look), zinc standing seam (contemporary), or tile hanging (blends with existing roof). The flat top is finished in GRP fibreglass or single-ply membrane. The junction between the mansard wall and the flat top is critical — we use continuous lead or zinc flashings with generous overlaps and proper drainage falls on the flat section. Every mansard we build in East London is designed for a 30+ year lifespan.
Hackney, Shoreditch, Bethnal Green: Victorian and Georgian properties dominate. Mansard Roofing work here typically involves natural slate, lime mortar, heritage-grade leadwork, and careful attention to conservation area requirements. Lead theft prevention is a major consideration.
Stratford, Bow, Canning Town: A mix of Victorian terraces, post-war estates, and Olympic-era new-builds. Mansard Roofing requirements range from traditional slate repair to modern membrane systems on contemporary apartment blocks.
Walthamstow, Leyton, Leytonstone: Edwardian terraces with decorative clay tiles and ornamental ridges. Mansard Roofing here often requires sourcing specialist tiles for the Warner Estate and careful handling of period features.
Barking, Dagenham, Ilford, Romford: 1930s suburban semis and the Becontree Estate. Mansard Roofing focuses on concrete and clay tile replacement, hipped roof valley repairs, and upgrading failing flat roofs on rear extensions.
Canary Wharf, Isle of Dogs: High-rise apartments and warehouse conversions. Mansard Roofing requires specialist membrane systems, rope-access capabilities, and experience with complex commercial roofing.

“Called about a small leak in our bay window roof. Turned out to be corroded zinc flashing. They replaced it with lead, dressed it properly, and it has been perfect for two winters now.”
“We manage fourteen flats across Tower Hamlets. They handle all our roof maintenance — annual inspections, gutter clearing, emergency repairs. Professional, reliable, and they actually turn up when they say they will.”
“Had them re-do all the guttering and fascias on our 1950s semi. Old cast iron removed, new black UPVC throughout. Huge difference — no more overflows and the front of the house looks ten years younger.”
