Cost Breakdown

New Roof Costs by Property Type in North London

Victorian Terraced House (Islington, Camden, Hackney, Holloway, Stoke Newington)

Typical roof area 50–70m². Standard concrete tile re-roof: £5,500–£8,000. Re-slate with reclaimed Welsh (conservation areas in Canonbury, Barnsbury, Angel): £8,000–£13,000. Butterfly roof valleys — characteristic of terraces on Leighton Road in Kentish Town and Evering Road in Stoke Newington — add £300–£600 per valley for lead relining. Scaffolding on a mid-terrace with limited access on Tollington Road or Drayton Park: £800–£1,200. End-terrace with two exposed elevations: £1,000–£1,600.

Edwardian Semi/Detached (Muswell Hill, Crouch End, Highgate, Hampstead)

Typical roof area 70–100m² with complex geometries — multiple gables, hips, decorative ridges. Standard clay tile: £8,000–£13,000. Heritage handmade tiles (Muswell Hill conservation area, Pages Lane, Alexandra Park Road): £12,000–£18,000+. Ornamental ridge crests and finials add £400–£1,200 sourcing premium. Multi-level scaffold on steep Highgate Hill or North Hill properties: £1,500–£3,000.

1930s Semi-Detached (Barnet, Finchley, Palmers Green, Southgate, Winchmore Hill)

Typical hipped roof 70–90m². Concrete tile re-roof: £6,500–£9,500. These roofs commonly need structural timber work — 90-year-old rafters and purlins may need sistering or replacement. Budget £1,000–£2,500 for timber. Sarking felt is always perished. Good access on wider suburban streets like Fox Lane, Ballards Lane, and Brookhill Road keeps scaffold costs to £900–£1,400.

Post-War Properties (Tottenham, Wood Green, Enfield, Edmonton)

The 1960s–70s concrete tile re-roofing on Victorian terraces along Philip Lane, West Green Road, and High Road Tottenham is now at end-of-life. Budget re-roof: £4,500–£7,000. These are the most cost-sensitive properties in our portfolio — we offer flexible payment staging (deposit, mid-point, completion) to make replacement accessible.

What North London Homeowners Say

★★★★★

"Full re-roof on our three-storey Victorian in Islington. Reclaimed Welsh slate to match the conservation area. They sourced perfectly — the neighbours couldn't tell old from new. Five-day job, immaculate cleanup."

Eleanor G. · Canonbury, N1
★★★★★

"Concrete tile replacement on our 1930s semi in Finchley. Stripped, replaced two rafters, new membrane, Marley Edgemere tiles. Done in 4 days and within the quote. Excellent value."

Peter J. · North Finchley, N12
★★★★★

"Re-roofed our end-terrace in Tottenham after the old 1970s tiles started crumbling. Budget was tight but they found a solution that worked. Staged payments made it manageable. Very fair."

David A. · Tottenham, N17
Why Us

Why North London Homeowners Choose Us

127 verified Google reviews with a 4.9-star average tell the story better than we can. Real homeowners across every North London borough — from Georgian terraces in Canonbury to 1930s semis in Southgate, Victorian houses in Crouch End to post-war properties in Tottenham — sharing their experience of honest diagnosis, transparent pricing, quality workmanship, and genuine aftercare.

We are not a national directory, a call centre, or a franchise. We are local roofers who live and work across North London. When we guarantee our work for 10 years, we are guaranteeing it as a business that depends on its reputation in communities from Hampstead to Hackney, Barnet to Islington. That accountability — combined with NFRC registration, £5 million public liability insurance, and a transferable written guarantee — is why homeowners, landlords, and property managers across North London trust us with their roofs.

If you have received a quote from another contractor and would like a second opinion, call 0203 538 0907. We are happy to inspect and advise — even if you go with someone else. Free inspection, free quote, no obligation. That is how confident we are in our pricing and our work.

Process

Our Roof Replacement Process

Survey & Spec

Thorough survey checking rafters, purlins, fascias, ventilation. Specification written to match property type, conservation requirements, and budget.

Strip & Inspect

Existing covering removed, every timber inspected. Rotten rafters sistered or replaced. Any hidden damage documented and discussed before proceeding.

Build Up

Breathable membrane, treated battens at correct gauge, tiles or slates fixed to BS 5534. Ridges, hips, valleys, lead flashings all completed. Ventilation installed.

Guarantee

Completion photos, written 10-year guarantee, manufacturer warranties. Your new roof should last 40-80+ years depending on material. Call 0203 538 0907.

Standards

Material and Installation Standards

Every material we install meets or exceeds the relevant British Standard. Tiles and slates are fixed to BS 5534, which specifies nail/clip requirements based on tile type, roof pitch, and wind exposure zone. Flat roofing membranes are installed to BS 6229, with minimum falls of 1:40 and proper upstand detailing at every abutment. Lead sheet work follows Lead Sheet Association guidelines — all joints bossed or welded, never sealed with mastic. Ridge and hip components use dry-fix mechanical systems compliant with BS 8612 where appropriate.

We specify materials from established manufacturers — Marley, Redland, and Forticrete for concrete and clay tiles. Topseal and Cure-It for GRP fibreglass systems. Firestone RubberCover and ClassicBond for EPDM membranes. BLM British Lead for sheet lead. These manufacturers provide product warranties of 15-30 years that supplement our own 10-year workmanship guarantee.

We never use cheap substitutes, reclaimed materials of unknown provenance (we source reclaimed slates and tiles only from reputable yards with verified origin), or materials below the specification required for the application. The difference between a roof that lasts 20 years and one that lasts 60 is almost entirely in the material specification and installation quality — not the price.

Second Opinion Service

If you have received a quote from another contractor and something does not feel right — the price seems too low, the specification is vague, or you are not confident in the diagnosis — call us for a free second opinion. We will inspect your roof independently, explain what we find, and provide our own quote. There is no charge and no obligation. We would rather you made an informed decision with another contractor than an uninformed one with anyone.

Call 0203 538 0907. Honest advice, no sales pressure, free inspections across all North London.

Real Example

A Typical North London Job

Last month a homeowner on a Victorian terrace in Islington called about persistent damp on their chimney breast wall. Two previous roofers had sealed the chimney flashing with mastic — the damp returned within weeks both times. We inspected and found the root cause: the lead step flashing had fatigue-cracked at every fold line after 90+ years of thermal cycling. Mastic was never going to fix a structural lead failure.

We stripped the failed flashing, raked the mortar joints, and installed new code 4 milled lead — properly stepped, bossed into the brickwork, and wedged with lead wedges. Total cost: £380 including scaffolding. The chimney breast dried out within three weeks and has remained dry through subsequent heavy rain. The two mastic repairs that preceded our work cost the homeowner a combined £450 and solved nothing.

This is a typical example of why accurate diagnosis matters more than fast, cheap fixes. Call 0203 538 0907 — we find the real problem and fix it properly the first time.

Your Guarantee

The North London Roofers Promise

Honest Diagnosis

We tell you what your roof actually needs — not what generates the biggest invoice. If a £150 repair will solve the problem, we say so. If the roof needs replacing, we explain why with photographs and evidence. No upselling, no scare tactics.

Transparent Pricing

Every quote is itemised: materials by manufacturer and specification, labour by task, scaffolding, waste removal. You see exactly what you are paying for. The quoted price is the final price — no hidden extras, no variations without your written approval.

Quality Materials

We specify reputable manufacturers — Marley, Redland, Forticrete, Topseal, Firestone, BLM. Never cheap substitutes. Material choice is the single biggest factor in how long your roof lasts. We get it right first time so you do not pay twice.

Written Guarantee

10-year workmanship guarantee, in writing, provided before we leave. Transferable if you sell. Material warranties from manufacturers provided separately — typically 15 to 30 years. NFRC registered, £5m insured. Your complete protection on every job.

Diagnosis

How We Diagnose the Problem

Accurate diagnosis is the foundation of every successful repair. We inspect from ladder level and, where safe, walk the roof surface. We check tile and slate condition, flashing integrity, ridge and hip mortar, valley linings, chimney stacks, guttering, and fascias. We use binoculars for areas that cannot be safely accessed and drone photography where the roof is too high or complex for visual inspection from a ladder.

Every issue is photographed and documented. We show you the images on a tablet or phone, explain what we have found in plain English, and outline your options — from the minimum intervention needed to the comprehensive solution. You decide how to proceed, with no pressure and no upselling.

If we cannot identify the source of a leak visually, we use controlled water testing — running water over small sections systematically while an observer watches inside. This isolates the exact entry point and prevents unnecessary work on areas that are not the problem.

Timelines

How Long Does the Work Take?

All timelines are weather-dependent. We provide a realistic schedule with every quote and communicate proactively if conditions require adjustment.

Access

Scaffolding and Access

We assess access requirements during your free inspection and quote scaffolding transparently as a separate line item. For minor repairs — a handful of tiles on a single-storey section — a roof ladder may be sufficient, saving you the scaffold cost entirely. For full re-roofs, chimney work, or multi-storey properties, scaffold is essential for safety and quality.

Typical North London scaffold costs: Mid-terrace with limited rear access (Holloway, Islington, Camden): £800–£1,400. End-terrace with two elevations: £1,000–£1,800. Semi-detached (Barnet, Finchley, Palmers Green): £1,000–£1,600. Detached (Muswell Hill, Highgate, Hampstead): £1,500–£3,000. Multi-level complex (four-storey Camden, steep Highgate Hill): £2,000–£3,500.

In North London, parking permits may be required for scaffold lorry access on resident-controlled streets. We manage permit applications with the relevant council (Islington, Camden, Haringey, Barnet, Enfield, Hackney) and include any permit costs in our quote.

What to Expect

Disruption and Weather

Noise: Tile stripping and battening generates significant noise. We start at 8am and finish by 6pm (earlier on Saturdays). We notify immediate neighbours before work begins.

Dust and debris: We use chutes and skips to contain waste. Dust sheets protect gardens, driveways, and parked cars. We sweep and clean at the end of each working day, not just at job completion.

Weather: We do not strip a roof unless the forecast supports completing the waterproof layer within the same day. If weather turns unexpectedly, we tarp immediately — your property is never left exposed overnight. Rain delays extend the programme but do not compromise quality. We communicate proactively if the schedule needs to adjust.

Living in the property: You can remain in your home during most roofing work. For full re-roofs, expect 3–8 days of activity overhead. We maintain safe access to all doors at all times and protect your garden and external areas throughout.
