Commercial Roof Cleaning – Concrete & Steel Roofing

Maintaining the roof of your commercial building is essential for both appearance and long-term performance. Concrete tiles and steel roofs on commercial properties require regular cleaning - ideally once a year - to prevent the build up of grime, moss, and environmental debris that can cause damage over time.

At Jani-King Blast-Off, we specialise in commercial roof cleaning across Auckland, using the right equipment, safety measures, and industry know-how to clean even the most challenging commercial roofs. Regular maintenance not only protects your building but also enhances its professional image.

For best value, pair your commercial roof wash with our full exterior building cleaning service. It’s a smart way to safeguard your property and make a lasting impression on clients and tenants alike.

Commercial Gutter Cleaning Auckland

Blocked gutters on commercial buildings can lead to serious issues - water damage, structural deterioration, and even health and safety hazards from mould or pests. Leaves, debris, and dirt quickly build up in guttering systems, especially on large commercial roofs, causing leaks and overflow that can damage both the exterior and interior of your building.

At Jani-King Blast-Off, we specialise in commercial gutter cleaning in Auckland, using high-performance equipment to clear blockages and ensure proper water flow. Our trained team works safely and efficiently, helping you protect your building, reduce long-term maintenance costs, and stay compliant with health and safety standards.

Trust Jani-King Blast-Off to keep your commercial gutters clean, clear, and performing at their best - Auckland-wide.

Using industrial-grade water blasting, we deep clean concrete and asphalt surfaces to restore their appearance and improve safety. Whether it’s a retail carpark, office entrance, or high-traffic walkway, we’ll have your exterior surfaces looking clean and professional.

Commercial Fence & Deck Cleaning Auckland

Outdoor timber surfaces at commercial properties - like fences, decks, pergolas, and verandas - can quickly accumulate dirt, moss, mould, and algae, impacting both appearance and safety. A clean, well-maintained exterior makes a strong impression on customers, clients, and staff.

At Jani-King Blast-Off, we provide professional commercial fence and deck washing services across Auckland, using commercial-grade water blasting and eco-friendly cleaning products. Our low-pressure system is safe for timber and delivers powerful results - restoring wooden surfaces to a clean, refreshed state.

To keep your exterior areas looking their best year-round, we recommend annual moss and mould treatments to prevent regrowth and extend the life of your timber.
