THE SHORT ANSWER

Less moss. Cleaner tiles. The roof you already have.

Roof cleaning removes surface growth and dirt. It reveals the existing tiles; it does not repaint them or repair underlying defects.

The work

A method matched to the roof, removal of moss and contamination, and debris management. Treatments are specified in the quote.

The quotation

Roof area, tile condition, access and the amount of growth determine the work and price.

The next step

Tell us your property type, postcode and main concern. We’ll discuss suitability and the proposed scope.

YOUR ROOF MIGHT NEED A CLEAN

Moss on Your Roof? Here's What It Can Mean.

Moss often starts in shaded areas and develops gradually. At first it's easy to overlook. Later you may notice thicker patches or debris washing towards gutters.

Moss doesn't automatically prove your roof is damaged.

It can, however, collect moisture and organic debris. Loose growth may contribute to gutter blockages, and a heavily contaminated surface can make it harder to see the condition of the tiles beneath.

The useful question isn't simply, “How do we remove it?” It's “What condition is this roof in, and which treatment is suitable?”

Moisture and organic growth

Shaded, damp conditions can encourage moss, algae and lichen. The significance varies with the roof material and condition.

Moss falling into gutters

Debris from the roof may restrict drainage and contribute to overflow during rain.

An older-looking roof

Moss and dirt can make serviceable tiles look more weathered than they are. Cleaning may reveal a much fresher original surface.

Existing damage is a separate issue

Cleaning doesn’t mend cracked tiles, failing mortar or problems below the roof surface. Those concerns require their own assessment.

Don't assume the worst because you can see moss. Start with the roof's actual condition.

OUR APPROACH

A Thorough Clean Starts With an Appropriate Plan.

Good roof cleaning is more than spraying the surface and hoping for the best. The roofing material, existing condition, contamination, access and surrounding areas all matter.

  1. Roof Review

    Consider the visible tile condition, material, moss growth and areas that may affect the cleaning method. An obvious defect may require further investigation first.

  2. Prepare the Surroundings

    Plan safe access and protect surrounding surfaces where appropriate. Identify how moss and debris will be managed during the work.

  3. Clean Using a Suitable Method

    Remove unwanted contamination using the agreed method appropriate to the substrate and its condition.

  4. Apply the Agreed Treatment

    Where specified, an appropriate biocide may be applied in accordance with its product instructions to discourage organic regrowth. Permanent prevention isn’t promised.

  5. Review and Tidy

    Inspect the completed agreed work and clear the debris from the agreed work areas. Any outstanding concerns should be explained.

  6. Explain Completion & Aftercare

    Review relevant completion information and explain appropriate aftercare, treatment limitations and any maintenance advice for your roof.

The right method matters more than a one-size-fits-all promise.

Coating preparation has separate requirements. It does not determine the method for every standalone roof clean.

THE METHOD SHOULD FIT THE ROOF

Different Roofs Need Different Treatment.

Roof tiles vary in material, age, finish and condition. A treatment that's appropriate for one property may not be for another.

That's why cleaning decisions should be based on the specific roof rather than an automatic method chosen before inspection.

Your roof isn't identical to your neighbour's. The cleaning approach shouldn't be assumed to be identical either.

Ask About My Roof Type

Concrete roof tiles

These can collect substantial moss and surface dirt. Their age and existing condition should be considered before cleaning.

Clay roof tiles

Clay surfaces vary. The tile type, finish and condition affect the suitability of a proposed method.

Slate and specialist materials

Not all materials are suitable for every cleaning technique or subsequent coating system. Some require specialist assessment.

Damage and fragile surfaces

Loose or cracked tiles, deteriorated areas or suspect materials must not be ignored to push ahead with cleaning.

Do you always pressure wash?

No universal cleaning method is right for all roofs. We’ll explain the appropriate method proposed for your property. Some roof-coating preparation systems have separate requirements.

If suspect asbestos-containing materials are found, work must stop for appropriate specialist advice.

Discuss existing tile defects

SEE THE DIFFERENCE

See What Professional Cleaning Can Change.

A roof covered in moss and surface dirt can look significantly older than the tiles beneath. Once contamination has been removed using a suitable method, the visual difference may be striking.

But a cleaning comparison should show cleaning — not a new coloured coating.

BEFOREAFTER CLEANING
Less moss. The same tile colour.

Actual results depend on the roof and treatment. Drag or use arrow keys to compare.

Before: Visible moss, lichen, algae and accumulated surface dirt.

After: Same roof tiles after cleaning, with their original material and colour still apparent.

Cleaning or Colour Coating?

Cleaning removes surface contamination. RENOTEC coating is a separate service that can restore or change the colour of compatible roof tiles and provides specified surface-protection properties.

LOOKING AFTER THE RESULT

What Happens After the Moss Is Gone?

Cleaning can dramatically improve a roof's appearance, but it doesn't remove the conditions that originally encouraged organic growth.

Weather, shade, overhanging trees and debris remain factors to keep an eye on over time.

A cleaner existing surface

Cleaning removes suitable surface contamination; it doesn’t replace damaged material or repaint faded tiles.

Treatment may help discourage regrowth

Where included and correctly applied, biocide can help manage organic growth. No treatment should be described as making a roof permanently moss-free.

Gutters still need checking

Leaves and debris can return after the cleaning visit. Maintaining drainage remains important.

Colour restoration is a separate decision

If the roof remains serviceable but the tiles have lost their colour, RENOTEC may be worth discussing. It isn’t automatically required after cleaning.

How Much Does Roof Cleaning Cost?

There isn't one meaningful price for every roof. The area to be treated, access requirements, existing condition, amount of moss and any agreed treatments all affect the work involved.

Your quotation sets out the roof areas, cleaning method, preparation, debris management and any additional treatment included. Ask us to explain access costs, exclusions and the total payable before agreeing to proceed.

Access and condition

Height, fragile materials, existing defects and safe access arrangements matter.

The agreed scope

Cleaning, appropriate biocide, gutter clearing and promotion extras need to be distinguished in the quotation.

View All Frequently Asked QuestionsExplore the Roof-Cleaning Process

Why Does Moss Grow on Roof Tiles?

Moss may develop where the roofing surface and surrounding conditions are suitable for growth. Shade, retained moisture and the nature of the roof material can all influence conditions. Different roof slopes may experience different levels of moss growth.

Can You Clean Concrete Roof Tiles?

Concrete roof tiles may be suitable for professional cleaning, depending on their condition, surface characteristics and the proposed method. Any damage or deterioration should be assessed before work is agreed.

Can You Clean Clay Roof Tiles?

Some clay roof tiles may be suitable for appropriately selected cleaning techniques. Clay roofing varies significantly in age, surface condition and manufacture, so suitability can't be guaranteed without assessment.

Can You Clean Natural Slate Roofs?

Natural slate and other sensitive roof coverings require particular care. A cleaning method suitable for conventional concrete tiles may not be appropriate for slate. Material-specific assessment or a specialist contractor may be necessary.

Does Roof Cleaning Remove Algae and Lichen?

Suitable professional cleaning may remove appropriate surface algae, lichen and other contamination. The method and achievable result depend on the roofing material and condition. Not every mark or discolouration can necessarily be removed without risk.

How Long Does a Roof Clean Take?

Duration depends on the property, roof size, contamination, access, method and weather. The proposed scheduling arrangements will be explained when the work is planned. No universal completion time can be guaranteed.

What Happens to the Moss and Debris?

The agreed quotation should identify the work-area clean-up and relevant debris-removal arrangements. Where Roof Revival includes additional gutter clearing or exterior cleaning, the scope should also be explained before work is agreed.

Can My Roof Be Cleaned If It Has Solar Panels?

Roofs containing solar panels may require additional care with access and protection of the installation. Panel cleaning, electrical work or removal and refitting of equipment must not be assumed to be included. The proposed roof cleaning must be assessed against the actual installation.
