Considering cleaning the roof?
Maintaining a clean roof is crucial for commercial buildings, extending beyond mere visual enhancement. Regular cleaning of your commercial property's roof acts as a preventative measure against potential structural damage. Investing in professional deep or soft washing services can be a cost-effective strategy, potentially saving on significant repair expenses in the long run.
Why should I consider roof cleaning?
- Prevents severe structural damage to your commercial building
- Maintains and manages moss on large roof surfaces
- Significantly cuts down on future repair costs
- Removes heavy build-up of algae, dirt, and debris from commercial roofs
- Makes wear and tear more noticeable, facilitating timely maintenance
- Prolongs the functional life of your business's roofing system
- Enhances the professional appearance of your property
- Ensures a clean roof with no regrowth for up to a decade, aiding in long-term maintenance planning
Our Cleaning Process: Tailored & Efficient
Our process begins with a detailed site assessment — we evaluate your roof's condition, confirm the most appropriate cleaning method, and schedule the work around your operating hours to cause minimal disruption to your business.
For most commercial roofs, we combine gutter clearing, pressure washing and biocide treatment to deliver a thorough, long-lasting result. For older or more vulnerable surfaces — including asbestos cement sheets, flat roofs and metal sheeting — we use soft washing, which achieves the same clean without the risk of pressure damage.
Once cleaned, every roof is treated with an environmentally safe biocide that actively prevents moss and algae from returning for up to 10 years.
Deep Roof Cleaning for Commercial Buildings
Maintaining a clean roof on your commercial premise achieves more than just aesthetic appeal, it helps prevent possible roof damage in the future, saving you costly repairs in the coming years.
When completing a deep roof clean, our innovative high quality performance jet wash removes moss, algae, lichens, dirt and grime, leaving your roof in a healthier, pleasing state. A state that has longevity, and improved kerb appeal.
Your roof is then treated with an environmentally friendly solution to remove any remaining moss or algae. This will prevent regrowth for up to 10 years - making it a sound investment for your business or commercial space.
While many are aware how unsightly moss is, especially on a commercial building, many don’t understand the effect it can have. Moss holds moisture against the roof, which can cause roofing materials to rot, this can lead to serious structural damage such as damp insulation and rotting timber. So if you spot moss on your commercial building, it’s important to act now.
Soft Washing
For commercial and industrial buildings with fragile or specialist roofing, including asbestos cement, corrugated metal, flat felt or EPDM roofs, soft washing is the right approach. It uses low-pressure application of a specialist biocide solution rather than high-pressure water, so there's no risk of damage to the roof material or fixings.
Initial results vary by roof type, with 90–95% of moss removed on first treatment. The biocide continues working over the following weeks and months, and the roof will appear fully clear within 3–6 months of application.
Soft washing is also a practical choice for large industrial or agricultural roofs where speed and cost-efficiency matter more than an immediate high-gloss result.
Please note: the solutions we use are safe for surrounding plants, animals and drainage.

Commercial Roof Cleaning — Frequently Asked Questions
How much does commercial roof cleaning cost?
Commercial roof cleaning prices depend on the size of the roof, the type of roofing material, the extent of moss or algae build-up, and the access required (scaffolding, cherry picker or flat ground access). We offer free, no-obligation site visits and fixed-price quotes for all commercial and industrial properties. Call 01362 685446 to arrange yours.
How long does commercial roof cleaning take?
Most commercial roof cleans are completed in one to two days. Larger industrial or agricultural buildings may take longer depending on roof size and the cleaning method used. We'll give you a clear timeframe as part of your quote so you can plan accordingly.
What types of commercial roofs do you clean?
We clean all common commercial and industrial roof types, including concrete and clay tiles, corrugated metal and steel sheeting, asbestos cement (fibre cement) panels, flat roofs (felt, EPDM, GRP), and pitched slated roofs on larger commercial buildings. If you're unsure whether your roof type is suitable, just call us and we'll advise.
Will the work disrupt our business operations?
We plan all commercial jobs around your operating hours. For most roofs, work is carried out entirely from above with no need to access the building interior, so day-to-day operations continue as normal. For particularly large sites or sensitive environments (food production, schools, healthcare), we discuss scheduling in advance to ensure zero disruption.
How often should a commercial roof be cleaned?
Most commercial roofs benefit from a professional clean every 3 to 5 years, though this depends on the surrounding environment. Roofs near trees, in shaded areas, or in coastal locations tend to accumulate moss and algae faster. Our biocide treatment after each clean prevents regrowth for up to 10 years, significantly extending the time between full cleans.
Do you clean asbestos cement roofs?
Yes. Asbestos cement (also called fibre cement) is one of the most common roofing materials on older industrial and agricultural buildings in the East of England, and we clean it regularly. We use soft washing — low-pressure application of a specialist biocide — which effectively removes moss, algae and staining without disturbing the roof surface or fibres. All work is carried out in line with current health and safety guidance.
What areas do you cover for commercial roof cleaning?
We cover the whole of the East of England within a 60-mile radius of our base in Dereham, Norfolk. This includes Norwich, Cambridge, Peterborough, Ipswich, Bury St Edmunds, King's Lynn, Great Yarmouth, and all surrounding towns and villages across Norfolk, Suffolk, Cambridgeshire, Lincolnshire, Essex, Bedfordshire and Northamptonshire.
What's the difference between pressure washing and soft washing for commercial roofs?
Pressure washing uses high-pressure water jets to physically remove moss, algae, dirt and staining — it delivers the most immediate visible result and is ideal for robust roof surfaces such as concrete tiles and most metal sheeting. Soft washing uses low-pressure application of a specialist biocide solution instead. It's gentler on the roof surface, making it the right choice for asbestos cement, older tiles, flat roofs and any surface where high pressure could cause cracking or damage. We assess every roof individually and recommend the right method before any work begins.
Roof Cleaning Prices
Pricing for commercial roof cleaning depends on several factors: the footprint of the roof, the type of roofing material, the level of moss or algae build-up, and access requirements (flat access, cherry picker, scaffolding).
We provide free, no-obligation site visits and quotes for all commercial and industrial properties. There's no commitment required — just a straightforward assessment and a fixed price before any work begins.
