Our Services
Roof Cleaning Services
Roof cleaning is one of the simplest and most effective ways to extend the life of your building and stay compliant with maintenance and safety standards.
Prevent Damage and Leaks
Moss, algae, and debris hold moisture, which can damage tiles, membranes, and drainage systems. Regular cleaning removes this build-up and helps stop leaks before they start. We remove it to prevent those unexpected, expensive leaks before they even start.
Health and Safety Compliance
Slippery roofs and blocked drains can pose hazards for maintenance teams or anyone accessing the roof. Our service strictly follows HSE working-at-height regulations, including full risk assessments, protecting your team and ours.
Energy and Structural Efficiency
A clean roof reflects heat more effectively and prevents blocked rainwater systems, helping your building stay energy efficient and structurally sound.
Protect Your Investment
Your roof protects everything underneath it. Keeping it clean reduces wear, prevents damage, and helps you meet insurance and warranty requirements.

Client Testimonials
What our commercial cleaning clients say
On behalf of B & E Boys I would like to thank you for all your help over the past few months, from last minute builders cleans to recently taking on one of our largest properties within our Property Portfolio. Aspin Group have been nothing but friendly and professional throughout everything so far, and your advice provided to us has also been invaluable. We look forward to continuing to work with you in the future.
I've been working with Aspin for a while now, and they consistently impress me with their deep expertise in their field. They are always willing to go the extra mile to ensure my needs are met, offering proactive solutions and clear communication throughout the entire process.
We started using Aspin in 2018 as a company we out grew our previous building and moved into a new one, leaving the 2 building to much for our inhouse cleaners. We have our regular cleaner who is reliable and who has been amazing through the current situation, we can ask them to change hours and do additional hours at any time. We have regular visits and audits asking if everything is OK and how can they improve anything to make things better. I would definitely recommend Aspin you feel like they care about your company as if it was their own .

FAQ
Commercial roof cleaning questions, answered
Everything you need to know about our cleaning services in Manchester and across the UK.
Can’t find what you need? Our team is ready to answer any specific questions about your site.
Why should I have my commercial roof cleaned?
Regular roof cleaning removes moss, algae, and debris that can cause leaks, block gutters, and shorten the lifespan of your roof. Over time, these build-ups hold moisture and can damage roof tiles, membranes, and drainage systems. A clean roof helps prevent leaks before they happen, keeps your building looking professional, and saves you money on costly repairs in the long run. It’s one of the simplest ways to protect your property investment.
How often should a roof be cleaned?
Most commercial properties benefit from professional cleaning every one to two years, depending on the roof type, surrounding trees, and local weather conditions. If your building is in an area with lots of moss or pollution, you might need a yearly clean to prevent damage. We can inspect your roof and recommend a maintenance plan that keeps it in great shape without unnecessary costs.
Do you work on large or industrial sites?
Yes, absolutely. Our teams regularly clean roofs on large-scale buildings such as warehouses, factories, schools, hospitals, and office complexes across the North West. We’re fully trained in safe access methods, including harness work, scaffolding, and MEWPs, so no matter the height or size of your site, we can complete the job efficiently and safely.
Are your cleaning products environmentally safe?
Yes. We only use biodegradable, COSHH-compliant biocides that are safe for roofing materials, surrounding landscaping, and drainage systems. These products effectively kill moss and algae without causing harm to plants or waterways, making them ideal for commercial properties that prioritise environmental responsibility.
Do you include gutter cleaning?
Yes. Gutter and downpipe cleaning come as standard with every roof clean. Blocked gutters can lead to leaks, damp walls, and even internal water damage, so we make sure rainwater can flow freely away from your building. It’s all part of keeping your roofline in proper working order.
