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.
Hampstead'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 Hampstead High Street, Heath Street, Flask Walk, Fitzjohn's Avenue, Haverstock Hill, Frognal 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 Hampstead — 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 Hampstead'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 Hampstead roof, we apply a zinc-based or copper-based biocide treatment that inhibits regrowth for 3–5 years. For properties in Hampstead'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 Hampstead homeowners.
Hampstead ranks among London's most valuable residential areas with housing spanning four centuries. Georgian cottages in Flask Walk have steep-pitched roofs with original handmade clay peg tiles. Grand Victorian and Edwardian houses along Fitzjohn's Avenue feature complex slate roofs with copper detailing. The conservation area imposes strict material requirements — synthetic slates and concrete tiles are routinely refused by Camden planners.
Stringent conservation area material restrictions make every repair in Hampstead more complex and expensive than equivalent work elsewhere. Extreme property values demand flawless finish quality. Handmade tile matching on 18th-century cottages, copper and lead theft risk on high-value properties, and complex access logistics in narrow village lanes and steep terrain are all defining challenges.
Our team regularly provides roof cleaning & moss removal on Hampstead High Street, Heath Street, Flask Walk, Fitzjohn's Avenue, Haverstock Hill, Frognal and surrounding residential streets throughout Hampstead.

"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 Hampstead. 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 Hampstead. 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 Hampstead'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.
