Frequently Asked Questions About Roof Cleaning
We’ve listed some of the most common questions we encounter about our roof cleaning.
Is roof cleaning suitable for all property types?
We offer tailored solutions for:
Residential homes – often affected by moss and organic buildup
Commercial buildings – where clean roofs support branding and compliance
Industrial units – where buildup can affect drainage, insulation, and safety
Do you offer roof cleaning maintenance plans?
Yes, our scheduled maintenance packages are ideal for commercial and industrial sites, with optional inspections, gutter clearing, and surface treatments included periodically to keep buildings in great condition.
Do you use chemicals during pressure washing?
Yes. Moss retains moisture, which can damage tiles, lead to frost cracking in winter, and increase the risk of water ingress. It can also block gutters and downpipes.
What roof cleaning methods do you use?
We use different cleaning methods depending on the type of roof we are working on.
Soft washing – for delicate or older roofs (low-pressure biocide application)
Steam cleaning – effective for commercial and industrial settings
Manual moss removal – where necessary before treatment
Biocide treatment – kills spores and prevents rapid regrowth
What’s the difference between roof pressure washing and soft washing?
Roof pressure washing uses high-pressure water to clean quickly but can damage delicate tiles. Soft washing uses low pressure and specialist cleaning solutions that kill moss and algae without damaging the roof.
Do you use any chemicals and are they safe?
Yes, we can use industry-approved biocides that are safe for your roof, garden, pets, and the environment. These treatments kill moss on your roof and helps prevent it from growing back.
How long does roof cleaning take?
It depends on the size and condition of your roof, but most jobs are completed in 1–2 days. We’ll give you a more accurate timescale after a site assessment or photo review.
Can you clean my gutters at the same time?
Yes. Gutter cleaning is often included or offered as an add-on service during roof cleaning.
How much does roof cleaning cost?
The cost of a roof cleaning service will vary depending on roof size, condition, access and chosen cleaning method. Contact us for a free quote.
