ACE London Roofing provides professional roof cleaning services across Central London. Moss, algae, lichen and black streaks don't just look bad — they silently damage your roof tiles, block gutters and shorten your roof's lifespan. Our specialist cleaning removes all biological growth safely and restores your roof to its original condition.

Why Roof Cleaning Matters
Moss and algae hold moisture against your roof tiles, accelerating freeze-thaw damage and cracking. Left untreated, a moss-covered roof can deteriorate 3–5 times faster than a clean one. Regular cleaning — every 2–3 years — is one of the most cost-effective ways to extend your roof's life and maintain your property's kerb appeal.
In Central London, pollution and damp conditions accelerate biological growth more than anywhere else in the UK. Our cleaning treatments are specifically formulated for urban environments and are safe for surrounding plants, gutters, and drainage systems.

Pre-Treatment Application
A specialist biocide is applied to kill moss, algae and lichen at the root — ensuring a deeper, longer-lasting clean.

Cleaning & Rinsing
Soft washing or low-pressure rinsing removes all debris without damaging tiles, pointing or underlays. Gutters are also cleared.

Frequently Asked Questions
How often should I have my roof cleaned in London?
+
In Central London, we recommend a professional roof clean every 2–3 years due to higher pollution levels and damp urban conditions. After a biocide treatment, many clients find their roofs stay clean significantly longer.
Will pressure washing damage my roof tiles?
+
For most tile and slate roofs, we use soft washing rather than high-pressure cleaning. Soft washing uses low water pressure combined with specialist cleaning solutions — it's completely safe for tiles, pointing, and underlays. High-pressure cleaning is only used on concrete and flat roof surfaces where appropriate.
How much does professional roof cleaning cost in London?
+
Roof cleaning costs depend on the roof size, pitch, and level of moss/algae growth. A typical terraced house in Central London starts from around £300–£600. We provide a free, no-obligation survey and written quote before any work begins.
How long does roof cleaning take?
+
Most residential roof cleaning jobs in Central London are completed in a single day. Larger properties or heavily affected roofs may take 1–2 days. The biocide pre-treatment is applied first and left to work before the cleaning stage begins.
Do you include gutter cleaning with the roof clean?
+
Yes — gutter clearance is included as standard with all full roof cleaning packages. Loose moss and debris removed from the roof are cleared from gutters and downpipes to ensure proper drainage.
