3. Key Cost Factors
Understanding what drives roof cleaning costs is essential for budgeting:
Roof Size & Material
- Per Square Metre Pricing: Basic cleaning generally costs between £8–£12 per m². For example, a 100 m² roof might cost between £800 and £1,200.
- Material Considerations: Delicate materials (e.g., slate or clay tiles) may require gentler cleaning methods, potentially increasing the price.
Cleaning Method
- Hand Removal: Around £8.24 per m²—ideal for delicate roofs and precise cleaning.
- Pressure Washing: Approximately £11.33 per m²—quick and effective for heavy build‑up, but with a risk of damaging fragile tiles.
- Softwashing: Ranges from £10–£15 per m²—combines low pressure with cleaning agents for long‑term algae and moss prevention.
- Chemical Treatments: Often used to kill moss and algae at the root; typically combined with a biocide application to delay regrowth.
Roof Pitch, Accessibility & Safety
- Steep Roofs: May incur a 15–25% surcharge due to additional safety measures.
- Access Requirements: Difficult-to-reach roofs may require scaffolding or special equipment, adding to the cost.
Moss Severity & Post-Treatment
- Moss Removal: Light moss can add an extra £200–£400, while heavy infestations may add up to £1,000.
- Biocide Treatment: Essential for prolonging the moss-free period; many professionals recommend re-treatment every 2–3 years.
These factors are supported by industry standards and reflect real-world pricing variations.
4. Methods of Roof Cleaning
Choosing the right cleaning method depends on your roof’s condition and material.
💡 Choosing the right roof cleaning method depends on your roof type, level of dirt/moss buildup, and long-term maintenance goals. Below is a comparison of the most common methods, along with their pros, cons, and estimated costs.
Roof Cleaning Methods & Their Benefits
- Pressure Washing
- Best For: Sturdy roofs (e.g., concrete, metal)
- Pros: Fast, highly effective for heavy buildup
- Cons: Risk of tile damage and water ingress
- Cost Example: £550–£700 for terraced houses
- Softwashing

- Cons: Labour-intensive; may require more frequent treatments
- Cost Example: £12–£16 per m² (softwash method)
- Manual Scraping
- Best For: Roofs with heavy moss/debris buildup
- Pros: Controlled removal; minimal water usage
- Cons: Slower process; labour-intensive
- Cost Example: £395–£495 for terraced houses (hand wash)
- Chemical Cleaning
- Best For: Severe moss/lichen issues
- Pros: Kills moss/lichen down to the roots; reduces regrowth
- Cons: Requires careful handling and proper disposal of chemicals
- Cost Example: Varies based on treatment type
💡 Tip: Always consult a professional to determine the best method for your roof type and condition.
5. Benefits of Regular Roof Cleaning
- Extending Roof Lifespan: Regular cleaning removes damaging moss, algae, and debris, thereby preventing leaks and prolonging the roof’s life.
- Preventing Structural Damage: A clean roof reduces moisture retention, which can lead to rot, wood decay, and pest infestations.
- Enhancing Curb Appeal: Clean roofs look much more visually appealing and can make the house look brand new, instead of looking run down.
Routine maintenance is an investment in both the appearance and structural integrity of your home.
6. Additional Costs to Consider
Beyond the base cleaning fee, be prepared for extra charges that may arise:
- Scaffolding & Access Equipment: For hard-to-reach or steep roofs, scaffolding may be required. We rarely require scaffolding to be put up, this is because we have our own access equipment such as access towers, equipment we can clean a roof from the ground with, etc.
- Protective Coatings & Treatments: Post-cleaning sealants or biocide applications can extend the cleanliness period and prevent regrowth. We include biocide for free with every roof clean.
- Roof Repairs: Cleaning may reveal underlying damage (e.g., broken tiles, leaks) that will require prompt repair.
Discuss all potential extras with your contractor for a comprehensive, all‑inclusive quote.
