Dormer, mansard, and hip-to-gable roofing for loft conversions. Structural and weatherproofing specialists. We cover Hackney, Stratford, Bow, Bethnal Green, Walthamstow, Leyton, Barking, Ilford, Romford, Dagenham, Canary Wharf, Shoreditch, and all surrounding areas.
East London’s diverse housing stock — from Victorian terraces to modern apartments — demands specialist loft conversion 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.
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. The right loft conversion type depends on your property’s existing roof structure, available headroom, and planning constraints. In East London, we build dormer conversions (flat-roof or pitched-roof box dormers that extend from the rear slope), mansard conversions (replacing the rear slope entirely with a near-vertical wall and flat top — maximises space), hip-to-gable conversions (extending a hipped roof to a vertical gable end — common on 1930s semis), and Velux conversions (roof windows only, no external structural changes — the simplest and cheapest option). Each type has different cost, planning, and structural implications.
Most loft conversions in East London fall under permitted development rights, meaning no planning permission is needed provided you stay within volume limits (40m³ for terraces, 50m³ for semis and detached). However, conservation areas in parts of East London can restrict or remove PD rights entirely. Article 4 directions may require full planning applications even for minor alterations. Building Regulations approval is always required regardless of planning status — covering structural calculations, fire safety, insulation, staircase design, and means of escape. We handle all Building Regs liaison and can advise on planning status before you commit.
The roof of your loft conversion is the most critical waterproofing element in your home — it is now directly above living space, not a cold loft. We use breathable membrane underlays, fully supported lead or GRP flashings at every junction, and enhanced ventilation to prevent condensation in the new warm roof structure. Dormer flat tops are finished in GRP fibreglass with a 25-year guarantee. Lead cheeks are specified to Code 5 minimum. Every detail is designed to keep water out for decades, not just pass the building inspector on day one.
Hackney, Shoreditch, Bethnal Green: Victorian and Georgian properties dominate. Loft Conversion 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. Loft Conversion 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. Loft Conversion 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. Loft Conversion 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. Loft Conversion Roofing requires specialist membrane systems, rope-access capabilities, and experience with complex commercial roofing.

“EPDM rubber roof on our garage. Clean installation, proper drainage, and the 20-year guarantee gives us peace of mind. Half the price of the GRP quote we had from another company.”
“Lead flashing stolen from our chimney for the third time. They fitted Ubiflex alternative flashings and SmartWater marked the remaining lead. Twelve months and no theft. Should have done it years ago.”
