ROOF CLEANING FOR BUSINESSES

Protecting your property and preventing costly repairs with trusted commercial roof cleaning.

Corporate Roof Cleaning

Commercial roof cleaning removes moss, algae, lichen, and debris to keep large roofs in good condition. Without regular cleaning, roofs can trap moisture, leading to leaks, drainage issues, and costly damage over time.

At Neptune Cleaning, we offer professional commercial roof cleaning services across Hampshire and Southampton for offices, schools, warehouses, and more. Our team works safely and efficiently to help maintain your building’s exterior, reduce long-term maintenance needs, and ensure compliance with health and safety standards.

Benefits Of A Clean Roof

Keeping your commercial roof clean helps protect your property and reduce long-term maintenance costs. Regular cleaning prevents moss, algae, and debris from building up, which can otherwise lead to water damage and structural issues. It also keeps drainage systems clear, improving water flow and reducing the risk of leaks. A clean roof also improves your building’s appearance, creating a more professional impression for anyone visiting or working on-site.

The Roof Cleaning Process

Our commercial roof cleaning service starts with a site assessment to understand your roof's condition and access needs. Based on this, we use either soft washing or high-heat steam to remove moss, algae, and debris safely. Where needed, we apply a biocide treatment to help prevent regrowth. All work is done safely and in line with best practices, ensuring minimal disruption to your site while protecting your building’s condition and appearance.

High-Heat

We use high-heat pressure washing, heating water to around 80–120°C to effectively break down tough grime and organic growth. This method delivers lasting results without relying on harsh chemicals.

Low-Pressure

Our low-pressure wash gently clears moss, algae, and dirt without harming tiles or mortar. It’s especially suited to older roofs, providing a safe and effective clean that helps maintain the roof’s condition over time.

Biocide

After our cleaning, we apply a biocide treatment to eliminate any leftover spores and stop regrowth. This helps keep your roof clean for longer and protects it from moisture damage in the future.
