Professional roof cleaning and moss treatment across North London. Restore your roof's appearance and extend its lifespan safely.
North London's tree-lined streets and damp climate create ideal conditions for moss, algae and lichen. Left untreated, moss retains moisture against tiles, forces under overlaps, and accelerates deterioration. We remove growth safely and apply preventative treatments.
Holloway's mature tree canopy creates the ideal conditions for moss colonisation — persistent shade, trapped humidity, and leaf debris that retains moisture against tile surfaces. North-facing roof slopes on Holloway Road, Seven Sisters Road, Hornsey Road, Drayton Park, Camden Road, Tollington Road and surrounding streets are worst affected, with some developing moss coverage thick enough to lift tile edges and trap water. The urban environment adds pollution particles that create a nutrient-rich surface layer accelerating biological growth beyond what you'd see in rural areas.
We never pressure wash roof tiles in Holloway — or anywhere. High-pressure water drives moisture under tiles, strips protective surface coatings, and can crack ageing tiles. Instead, we apply a professional-grade biocide solution that kills moss, algae, and lichen at the root. After 2–3 weeks the dead growth is brushed off gently. On Holloway's older tiles — particularly the handmade clay tiles on Edwardian properties — this gentle approach preserves the tile surface while eliminating biological growth completely.
After cleaning your Holloway roof, we apply a zinc-based or copper-based biocide treatment that inhibits regrowth for 3–5 years. For properties in Holloway's most shaded locations, we recommend zinc ridge strips — thin zinc strips fitted beneath the ridge tiles that release natural fungicide with every rainfall, providing continuous protection across the entire roof slope. At £8–£12 per metre, they're one of the most cost-effective long-term roof maintenance investments for Holloway homeowners.
Holloway is one of North London's most densely populated areas with row after row of Victorian terraced houses lining streets off Holloway Road and Seven Sisters Road. Properties are typically two-storey with rear extensions and many have had loft conversions. The older stock features a mix of slate and concrete tile roofs — many originals were replaced after wartime bomb damage with whatever materials were available in the post-war period.
Mixed materials from post-war bomb damage repairs create inconsistent weatherproofing across Holloway's roofscape. Loft conversion dormer flashing failures, high density making scaffold access complex and expensive, Victorian party wall flashings deteriorating, and flat roof ponding on rear kitchen extensions are the problems we fix most often.
Our team regularly provides roof cleaning & moss removal on Holloway Road, Seven Sisters Road, Hornsey Road, Drayton Park, Camden Road, Tollington Road and surrounding residential streets throughout Holloway.

"Soft-washed the entire roof and applied biocide treatment. The moss was so thick it was lifting tile edges. Two weeks later the moss was dead, they returned to brush off the debris. Roof looks new."
"Moss removal, tile replacement where growth had damaged them, and zinc strip installation along the ridge to prevent regrowth. Comprehensive and well-explained."
"They cleaned our roof without pressure washing — important because our tiles are old and fragile. The biocide treatment has kept moss at bay for over a year now."

Spring (March–May): The ideal time for a professional inspection in Holloway. Winter damage is visible — cracked mortar, displaced tiles, failed flashings — and you're ahead of the autumn storm season. Book a free inspection now and address any issues before they worsen over summer.
Summer (June–August): The best conditions for major roofing work in Holloway. Dry weather allows full strip-and-retile projects, flat roof installations, and chimney rebuilds. Lead work is easier in warm temperatures when the metal is more malleable. If you're planning a roof replacement, summer is the optimal window.
Autumn (September–November): Clear gutters and valleys of leaf debris — critical in Holloway's tree-lined streets. Check ridge tiles and flashings before winter storms arrive. A pre-winter roof check costs nothing (we do it free) and can prevent expensive emergency repairs in December and January.
Winter (December–February): Emergency repairs only where possible. Frost, ice, and short days limit what can be safely done on a roof. However, if you have an active leak or storm damage, we respond same-day regardless of conditions. Call 0203 538 0907 any time — 24/7 emergency line.
Your roof is your property's first line of defence and its condition directly affects market value. A surveyor's report flagging roof defects can reduce offers by £10,000-£30,000 — far exceeding the cost of proactive maintenance. In Holloway, where property values are significant, roof condition is scrutinised closely by buyers, surveyors, and mortgage lenders.
We recommend annual inspections (free with us) to catch developing issues before they cause internal damage. Biannual gutter clearing — once after autumn leaf-fall, once in spring — prevents water backing up under tiles. Prompt repair of cracked tiles, failing flashings, and loose ridge tiles costs £80-£400 and prevents the £1,500-£5,000+ repair bills that follow water ingress left unchecked.
For Holloway properties in conservation areas, maintaining original roofing materials in good condition is not just good practice — it may be a legal requirement. Allowing heritage materials to deteriorate beyond repair, forcing replacement, can attract enforcement action from the local planning authority. Regular maintenance preserves both the material and compliance.
We offer annual maintenance packages covering gutter clearing, roof inspection, and written condition reports. Many of our Holloway customers have been with us for years, maintaining their roofs proactively at minimal annual cost. Call 0203 538 0907 to discuss a maintenance plan for your property.
Act immediately: Active leaks, storm damage, structural concerns, tiles on the ground, chimney stack leaning. These are emergencies — call 0203 538 0907 now. Same-day response, 24/7.
Act within 2 weeks: Visible missing or slipped tiles, cracked flashings, moss lifting tile edges, gutters overflowing in rain, damp patches on ceilings or walls. These are not emergencies but will worsen with each rainfall. Book a free inspection now.
Plan within 3 months: Ridge mortar crumbling, concrete tiles past 40 years old, flat roof felt blistering, fascias showing paint peeling. These indicate materials approaching end-of-life. Get quotes now and schedule work before the next winter.
Annual maintenance: If none of the above applies, an annual gutter clean and roof inspection (free initial, £170-£250/year thereafter) keeps your North London roof in optimum condition. Prevention is always cheaper than cure. Call 0203 538 0907.
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.
All timelines are weather-dependent. We provide a realistic schedule with every quote and communicate proactively if conditions require adjustment.
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.
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.
