How much does it cost to clean a roof?

The cost of roof cleaning can vary depending on the method used and the size of the roof:

• Hand Removal/Biocide Treatment: Typically costs about £11.50 per square metre, effective for removing moss and preventing regrowth.
• Pressure Washing: Costs around £8.50 per square metre and is suitable for removing dirt, grime, and some moss.
• Steam Cleaning: Priced at approximately £11 per square metre, ideal for delicate tiles that require gentle cleaning.
• Soft Washing: Generally costs £18 per square metre and involves applying chemicals that remove and protect against organic growth.

How long does it take to get a roof cleaned?

• Detached Houses: Typically takes about 6-7 hours, with labour costs ranging from £550 to £600.
• Semi-Detached Houses: Cleaning can take 4-5 hours, costing between £350 and £450.
• Terraced Houses: Usually takes 3-4 hours, with costs between £450 and £500.
• Bungalows: Takes about 3-5 hours, costing between £300 and £450.

The time and cost might vary based on the roof size and the degree of dirt or moss accumulation.

How do I know if the job has been done well?

To ensure that a roof cleaning job has been performed to a high standard, several indicators should be evident upon completion:

• Moss Color Change: Properly treated moss should change colour, usually turning white, yellow, or brown, indicating that it has been effectively neutralised and will not continue to grow.
• Clean Appearance: The roof tiles should appear uniformly clean, with no streaks, stains, or patches of dirt or algae. The overall look should be refreshed and noticeably improved compared to before the cleaning.
• Intact Roof: The cleaning process should not cause any damage to the roof tiles or the overall structure. There should be no cracked tiles or dislodged elements; everything should remain intact and secure.
• No Residual Debris: A well-done roof cleaning job includes thorough cleanup after the process. There should be no leaves, dirt, or cleaning residue left behind in gutters or on the roof itself.
• Effective Drainage: Post-cleaning, the roof’s drainage system (gutters and downspouts) should be clear and functioning properly, without any blockages that can lead to water accumulation.
