What Happens If You Leave Moss Growing on Your Roof?

A little moss is normal on many roofs and is often harmless. It is worth removing when it builds up, because heavy growth holds water against your tiles and its debris ends up in your gutters.

Left alone, heavy moss can cause, or hide, real problems:

  • Blocked gutters and downpipes as moss and debris wash down from the roof
  • Water held against the tile surface, which can speed up weathering
  • A higher risk of leaks where heavy build-up sits for years
  • Ridge and valley mortar that stays damp and is harder to check
  • Cracked or slipped tiles hidden under the growth until they cause a leak

    • A professional clean with a protective biocide treatment removes the growth and helps protect your tiles. It also lets us see your roof properly, so any repairs can be spotted and dealt with early.

3 Professional Roof Cleaning Methods – Find the Right One for Your Roof

Not every roof should be cleaned the same way. During your free survey we assess your tile type, roof condition and moss build-up, and recommend the method (or combination) that suits your home best.

roof cleaning before and after results

Where the roof allows, we work with ground-based telescopic equipment. Where the survey shows a safe working platform is needed, we use a scaffold tower. Your surveyor confirms which in your quote.

Manual moss scraping - No water pressure

Moss is carefully scraped from the tiles with specialist pole-mounted tools, with no water pressure at all.

  • Ideal for older or delicate tiles
  • Uses no water on the roof surface
  • Finished with a brushed-in biocide treatment

The biocide treatment included in your clean slows moss and algae coming back. For the best result we recommend a simple re-treatment every 1 to 2 years: a quick visit with no full clean needed.

Specialist low-pressure wash - Reduced pressure

A flat-surface cleaning tool at carefully reduced pressure covers the tiles evenly and gently, a very different approach from high-pressure jet washing.

  • Gives a clear visible improvement on suitable roofs
  • Test patch first, always
  • Used on sound concrete and clay tiles once the survey confirms they suit it, and never on older or fragile tiles

Soft wash treatment - Solution-based

A professional cleaning solution is applied and left to work, killing moss, algae and lichen with no mechanical action.

  • Best for light growth and fragile surfaces
  • A gradual result as the growth dies back and washes away
  • Minimal physical impact on the tiles

Roof Cleaning FAQ

Will pressure washing damage my roof?
Not the way we do it. Damage happens when untrained operators blast tiles with high-pressure turbo nozzles. We use a specialist flat-surface tool at carefully reduced pressure with wide fan jets for even, gentle coverage - and we always test a small patch first. For older or delicate tiles we switch to manual scraping or a soft wash instead.
How much does roof cleaning cost?
Every roof is different, so we price every job individually. Book a free, no-obligation survey and you'll receive a fixed written quote for your exact roof. The price we quote is the price you pay.
How long will my roof stay clean?
It depends on your roof, how much shade and tree cover it has and which way it faces. The biocide treatment included in your clean slows regrowth, and we recommend a simple re-treatment every 1 to 2 years to keep your roof protected without needing another full clean.
What happens to the moss and debris?
We collect all the debris and clear your gutters. Where it is suitable, we'll leave the organic matter where you choose in the garden, or bag it into your garden waste bin.
Do I need to do anything before you arrive?
Just make sure we have access to an outside tap and the work areas. It's also worth letting your neighbours know, as there can be minor overspray, which we'll clear up.
What if you find damage on my roof?
Heavy moss can hide issues such as cracked tiles or failing mortar, which become visible once the roof is cleaned. We'll give you a roof condition report and can recommend a trusted roofing contractor for any repairs, so you are never left guessing.
Is the treatment safe for my family, pets and garden?
We use professional biocides, applied by trained operators in full PPE and in line with the product label. We protect your planting, block your downpipes so the treatment is not washed into the drains, and manage run-off carefully. Please keep children and pets away from treated areas until they are dry. We'll tell you how long that takes for the product we use.
What roofs can't you clean?
We assess every roof individually during the free survey, and fragile roofs get our gentlest methods. If a roof isn't safe to clean, for example because of structural problems or asbestos-containing materials, we'll tell you at the survey, explain why and won't quote for work we can't do safely.
