UK-Based Specialists in Roof Cleaning
APT ICC provides professional roof cleaning services across England and Wales, working with industrial, commercial, healthcare, and public-sector clients to safely clean and maintain a wide range of roof types. Roof cleaning focuses on removing algae, lichen, moss, and environmental debris that naturally build up over time and can lead to blocked drainage, surface damage, or hidden defects.
The service is sometimes referred to as industrial roof cleaning, cladding roof cleaning, or flat roof cleaning, depending on the building type and roof structure. While the names may differ, the aim is the same: to clean roof surfaces thoroughly while protecting the roof system and maintaining site safety. Roof cleaning is commonly required on factory buildings, manufacturing sites, hospitals, offices, and other large properties with cladding or flat roofs.
APT ICC cleans a wide range of roof surfaces, including cladding roofs, large flat roofs, tiled roofs, and roofs with integrated solar panels. Cleaning is often carried out to prevent long-term damage, improve water flow, or allow inspections to take place. In many cases, roof cleaning also improves the efficiency of solar panels by removing dirt and biological growth that can reduce performance.
All roof cleaning works are carefully planned and assessed before starting. Access can be provided using specialist lifting equipment, edge protection systems, or other safe working methods depending on the building layout and live site conditions. This allows works to be carried out safely with minimal disruption to ongoing operations below.
With over 35 years of experience, APT ICC is trusted to deliver roof cleaning on sensitive and live sites across England and Wales. Recent projects include cladding roof cleaning at NMC in Tredegar, tiled roof cleaning at Singleton Hospital in Swansea, and flat roof cleaning at Usk County Hall. All works are completed under strict health, safety, and environmental controls, ensuring reliable results and long-term protection for roof assets.

Roof cleaning removes moss, algae, lichen, and debris that build up over time. This helps protect the roof surface and improve drainage. Clean roofs are also easier to inspect for defects or damage.
Yes. Built-up growth and debris can block outlets and trap moisture. Removing this allows water to drain properly and helps reduce the risk of leaks and long-term damage.
Minor tasks may be possible on small, accessible roofs. However, most commercial and industrial roof cleaning involves working at height and requires specialist access and safety controls. Incorrect methods can damage the roof or create safety risks.
Roof cleaning can be carried out on flat roofs, cladding roofs, tiled roofs, and roofs with solar panels. Each roof type needs a different approach to avoid damage. An assessment is carried out before work starts.
Yes, when properly planned. Roof cleaning is often carried out while buildings remain in use, with controls in place to protect people and areas below. Works are scheduled to minimise disruption.
This depends on location, exposure to trees or pollution, and roof type. Some roofs benefit from periodic cleaning as part of planned maintenance. Regular cleaning helps avoid more serious issues later.
Yes. Removing dirt and biological growth can improve light exposure and efficiency. Clean roofs also make it easier to maintain roof-mounted systems.
Yes. In addition to cleaning, biocidal treatments can be used to slow regrowth. APT ICC can advise on suitable professional-grade products, including those manufactured by APT Commercial Chemicals, used across England and Wales.
