Published: 2026-01-01 — East London Roofers
A new roof is one of the biggest investments you will make in your East London home. Getting an accurate idea of costs before you start is essential for budgeting, comparing quotes, and avoiding nasty surprises. Here are real 2026 prices based on our completed projects across East London.
Mid-terrace house (2–3 bed, slate): £5,500–£8,500. This covers scaffolding, stripping the existing roof, inspecting and repairing timbers, breathable membrane, battens, new natural slate, ridge tiles, and all flashings. Timescale: 3–4 days.
End-terrace house (slate or tile): £6,500–£10,000. The extra exposed side wall means more flashing work, and the additional hip or gable end adds complexity. Timescale: 3–5 days.
Semi-detached house (tile): £7,000–£12,000. Larger roof area with a full hip end or valley between the main roof and extension. Concrete interlocking tiles are the most common and cost-effective choice. Clay tiles add 15–25% to the cost. Timescale: 4–6 days.
Detached house (tile or slate): £12,000–£20,000+. The largest domestic roof type with the most complex geometry. Multiple hips, valleys, and often a garage or extension to integrate. Premium materials and extensive scaffolding push costs higher. Timescale: 5–8 days.
Flat roof replacement (per m²): GRP fibreglass: £75–£95. EPDM rubber: £60–£80. Torch-on felt: £45–£65. A typical garage flat roof (15m²) costs £1,000–£1,500. A rear extension flat roof (20–30m²) costs £1,500–£3,000.
According to the Royal Institution of Chartered Surveyors (RICS), a new roof typically adds 5–10% to a property’s value and is one of the most effective investments for long-term property maintenance. Source: RICS Building Survey guidance.
Roof size and complexity. A simple gable roof with no dormers or valleys costs less per square metre than a complex roof with multiple hips, valleys, and abutments. More complexity means more cutting, more flashings, and more labour.
Material choice. Natural Welsh slate is the most expensive option (£40–£80 per m² for material alone). Spanish slate offers excellent quality at £25–£40 per m². Concrete interlocking tiles are the most affordable at £15–£25 per m². Clay plain tiles sit between slate and concrete at £30–£50 per m².
Access and scaffolding. Easy access from the street: £600–£1,200 for scaffolding. Rear-only access or restricted frontage: £1,200–£2,500. Multiple scaffold lifts for taller buildings add further cost.
Timber condition. If the existing roof structure is sound, the quote covers stripping, underlay, battens, and new covering. If rafters, purlins, or wall plates are rotten, replacement adds £500–£3,000+ depending on the extent. A good roofer will always inspect timbers before quoting and flag any uncertainty.
Insulation upgrade. Adding or upgrading roof insulation during a re-roof is the most cost-effective time to do it. Budget £1,000–£3,000 for between-rafter or above-rafter rigid board insulation to meet current Building Regulations.
Hackney, Bow, Bethnal Green, Shoreditch (Victorian terraces): £5,500–£8,500 for slate. Conservation area restrictions may require specific slate types, adding 10–20% to material costs.
Walthamstow, Leyton, Leytonstone (Edwardian terraces): £6,000–£9,000 for slate or clay tile. Warner Estate properties may need heritage-grade materials.
Barking, Dagenham (Becontree Estate): £6,500–£10,000 for concrete tile on hipped roofs. The hip roof design of Becontree homes adds complexity versus simple gable terraces.
Ilford, Romford (1930s semis): £7,000–£12,000 for concrete or clay tile. Standard suburban semi with hip end and front bay.
Be cautious of any quote that does not include: scaffolding costs, waste disposal, timber inspection, underlay specification, tile or slate specification by manufacturer and profile, ridge fixing method, and flashing material and code. If a quote is just a single number with no breakdown, get a second opinion.
Also beware of quotes significantly below the ranges above. Cutting corners on materials, skipping timber inspection, or using unqualified labour will cost you more in the long run.
