Roof cleaning is an essential maintenance task for homeowners and commercial property owners alike. A clean roof not only enhances the appearance of your property but also protects its structural integrity and improves energy efficiency. However, the cost of commercial roof cleaning varies depending on the size of the property, the cleaning method used, and the accessibility of the roof.
In this guide, we’ll explore the typical costs of roof cleaning in the UK, the methods available, and why regular roof maintenance is a worthwhile investment.
Why is Roof Cleaning Important?
Roof cleaning helps to:
- Prolong Roof Lifespan: Removing dirt, moss, and algae prevents damage that can lead to leaks and costly repairs.
- Improve Energy Efficiency: A clean roof reflects heat better, keeping your property cooler and reducing energy bills.

Factors Influencing Roof Cleaning Costs
1. Size of the Property
Larger roofs require more time, labour, and materials, increasing the overall cost.
2. Roof Condition
Older or heavily moss-covered roofs may need additional work, such as moss removal or repairs, which can raise the price.
3. Cleaning Method
The method used impacts the cost significantly. Pressure washing and soft washing are typically more expensive than manual scraping due to equipment and labour requirements.
4. Accessibility
Roofs that are hard to access, such as those on taller buildings or properties with limited surrounding space, may require specialist equipment, increasing the cost.
5. Geographic Location
Prices can vary depending on your location in the UK. Urban areas may have higher labour costs compared to rural locations.
Roof Cleaning Methods
Different roof cleaning methods are suited to different roof types and conditions. Here’s an overview of the most common methods:
1. Pressure Washing
- How It Works: High-pressure water jets remove dirt, debris, and moss from the roof tiles.
- Best For: Concrete, slate, or clay tiles in good condition.
- Cost: £700 – £4,500 (varies by property size).
2. Soft Washing
- How It Works: A gentle, low-pressure wash combined with a cleaning solution to break down organic growth and stains.
- Best For: Delicate or older roofs. Often used as a final treatment after pressure washing or scraping.
- Cost: Included in pressure washing or scraping packages.
3. Roof Scraping
- How It Works: A manual method using a wire brush or scraping tool to remove moss and debris.
- Best For: Older or delicate roofs unsuitable for pressure washing.
- Cost: £600 – £3,500 (varies by property size).
4. Moss Removal Only
- How It Works: Focused removal of moss using manual scraping or specialised tools.
- Best For: Maintaining roof appearance between major cleanings.
- Cost: £400 – £2,100 (varies by property size).
Choosing the Right Cleaning Method
Selecting the best cleaning method for your roof depends on several factors:
- Roof Condition: Delicate or older roofs are better suited to scraping or soft washing.
- Budget: Pressure washing typically offers the most immediate and visible results but may be more expensive.
- Desired Outcome: For a deep clean and long-lasting results, pressure washing followed by soft washing is ideal.
Benefits of Regular Roof Cleaning
- Prevents Structural Issues
Moss, debris, and algae can trap moisture, leading to leaks and weakened roof materials. - Improves Energy Efficiency
A dirty roof absorbs more heat, increasing cooling costs in warmer months. Cleaning your roof improves its reflectivity, reducing energy consumption. - Avoids Costly Repairs
Regular cleaning removes harmful buildup that can cause long-term damage, saving money on repairs or replacement. - Maintains Aesthetic Appeal
A clean roof enhances the overall look of your property, boosting curb appeal and property value. - Protects Loft Spaces
Excessive moss and debris can cause water pooling, leading to issues like loft condensation and insulation damage.
