Edwardian properties dominate — large three-storey bay-fronted houses along Streatham Common North and South. Victorian terraces between Streatham High Road and Tooting Bec Common. 1930s semis towards Norbury. Post-war estates including Leigham Court Estate.
For flat roofing specifically, this housing mix creates distinct demands. Welsh slate on Victorian terraces, clay plain tiles on Edwardian stock, concrete interlocking on 1930s onwards. Many Edwardian properties have original clay tiles now 110+ years old. Complex roof forms with dormers, bay projections and valleys. — and each roof type requires different materials, methods and experience to repair or replace correctly.
Streatham Common creates a wind channel between Norwood and Tooting that drives rain against west-facing slopes with more force than sheltered streets either side. Properties facing the common take measurably harsher exposure than those one street back. For flat roofing work, this means materials and methods must be specified for Streatham's particular conditions — not generic South London assumptions.
Large Edwardian roof forms along Streatham Common create complex valley junctions — valley lead failures are the most common high-value repair. Bay window roof junctions leak where they meet the main wall on three-storey Edwardian houses. Shared chimney stacks on Victorian terraces create repair cost disputes.
Every flat roofing job in Streatham starts with a proper inspection — from the roof, not the pavement. We photograph the issue, explain the cause, and give you a written quote with no hidden costs. Most minor work is completed same-day. Larger projects are scheduled within days and we keep you updated throughout.
GRP (fibreglass) creates a seamless, rigid, walkable surface — ideal for balconies, roof terraces and areas that take foot traffic. It is the premium option at £60–80/m² installed. EPDM (rubber) is flexible, lightweight and excellent for large uninterrupted areas like garage roofs and extensions — £40–60/m² installed. It cannot be walked on regularly. Traditional felt remains the cheapest option at £25–40/m² but has a 10–15 year lifespan versus 30–40 years for GRP and EPDM. We recommend based on your specific roof layout, usage requirements and budget — not a one-system-fits-all approach.
Three things kill flat roofs: ponding water (insufficient drainage falls), thermal cycling (membrane expansion and contraction cracking joints), and poor detailing at upstands and edges. We address all three by specification: minimum 1:40 falls using tapered insulation, high-quality membrane systems rated for UV and thermal exposure, and meticulous attention to every edge, upstand, outlet and penetration detail. The deck underneath is equally critical — we inspect and replace any compromised timber before the new membrane goes down. Cheap flat roofs fail because someone skipped these steps. Ours do not.
After installation we provide a maintenance guide specific to your system. GRP needs annual inspection of joints and trim edges. EPDM needs checking for punctures and debris around outlets. Both need gutters and outlets clearing twice a year. We offer a maintenance visit service — annual inspection and minor attention for a fixed fee. This protects your guarantee and catches issues before they become problems. Most flat roof failures between 5–15 years are maintenance failures, not product failures.
Edwardian properties dominate — large three-storey bay-fronted houses along Streatham Common North and South. Victorian terraces between Streatham High Road and Tooting Bec Common. 1930s semis towards Norbury. Post-war estates including Leigham Court Estate. This means flat roofing work in Streatham must account for the specific roof types, materials and structural conditions found here — not generic assumptions about South London properties.
Streatham Common creates a wind channel between Norwood and Tooting that drives rain against west-facing slopes with more force than sheltered streets either side. Properties facing the common take measurably harsher exposure than those one street back. These conditions directly affect how we specify materials and methods for flat roofing work. A repair that holds in sheltered Camberwell may not survive the same winter on an exposed Streatham roof without the correct specification for local conditions.
