What is roof cleaning?

Roof cleaning is the careful removal of moss, algae, lichen, and surface dirt from roofing materials such as concrete tiles, slate, fibre cement, stone, and metal. Unlike basic washing, professional roof cleaning focuses on protecting the integrity of the roof while eliminating organic growth at its root.

A professional clean reveals the true condition of the tiles and allows problems to be identified early, before they become costly. We use sensitive, roof-appropriate methods that could include: pressure washing, dry scraping, steam cleaning, soft washing and biocidal treatments - or any combination of these to avoid unnecessary damage and ensure lasting results.

Prevent Tile Damage and Water Ingress

We avoid high-pressure washing where it might cause harm to the roof. Instead, we use a combination of dry scraping, soft washing, and specialist treatments to achieve the best possible outcome for your roof..

Our roof cleaning ensures:

• Safe removal of organic growth: moss, algae, and lichen are removed without damaging tiles or forcing water beneath them.

• Bespoke method suitable to your roof type: cleaning methods are selected based on the surface material and condition of your roof.

• More than just appearance: roof cleaning improves drainage, reduces wear, and helps prevent leaks and structural stress.

Roof Cleaning Process

Step 1 - Roof Assessment

A full assessment of your roof, considering its pitch, surface material, access requirements, and the extent of organic growth. Safe access is always a priority, and so we use roof ladders, temporary roof anchors and powered access equipment where required.

Step 2 - Manual Moss Removal

Moss is dry-scraped by hand, as it sits proud of the tile surface and cannot be fully removed by washing alone. 

Step 3 - Minor Repairs (when required)

Minor roof repairs such as replacing slipped or broken tiles, repointing ridge tiles, reseating flahing can be carried out at this stage when required / requested. You will always be provided with an additional quote if further cost will be incurred.

Step 4 - Soft Washing / Pressure Washing

Algae, dirt, and fungal growth are removed using controlled methods that are safe for that specific roof.

Step 5 - Biocidal Protection

A professional, government-approved biocidal treatment is applied to kill remaining spores and inhibit regrowth at a microbiological level.

Step 6 - Clean Up / Gutter Clearance

A full clean up around walls and ground level of house to ensure all moss or debris has be removed and that gutters and downpipes are free-flowing.

Soft Wash or Pressure Washing?

Our extensive experience in both pressure washing and soft washing roofs enables us to provide you with the very best advice when it comes to the appropriate method of cleaning your roof. To evaluate this, we consider:

• The surface material and structure. Hard-wearing tile materials such as concrete can often withstand the fast and impressive results of pressure washing. Whereas slate or fibre-cement, especially if old and worn, may be better suited to soft washing.

• Access to the roof. If access is limited or the roof itself is unsafe, we may advise soft washing the roof. Soft washing can often be achieved from ground level with ladders.

• Your desired outcome. Pressure washing brings about immediate noticeable results, but without chemical treatment re-growth can occur within 12 months. Conversely, soft washing brings an immediate, lesser change but continues to work, having killed the moss or lichen growth at its roots, for months afterwards. And a combination of both methods brings immediate impact and lasting protection.

Benefits of Roof Cleaning and Moss Removal

Moss holds moisture and becomes heavy then expands when frozen. All of this can significantly reduce the lifespan of your roof.

Blocked gutters are one of the most common problems caused by moss. As moss falls from the roof, it fills gutters and downpipes, leading to overflowing water, damp walls, rotten fascias and soffits, and even foundation damage. Left untreated, these issues can quickly escalate.

A clean roof also makes a strong first impression. Whether you are maintaining your home or preparing it for sale, a well-kept roof improves curb appeal and can positively influence surveys and valuations.
