What does rooftop-tank cleaning cover?
A rooftop tank differs from a ground tank in one important way: nothing shields it. Summer heat raises the temperature inside it and encourages green algae and a slimy film to form on the walls. The fine dust that hangs over finds its way through any gap or a lid that no longer seals properly, and so do insects and birds that land on the roof.
We start when you call or message us on WhatsApp, tell us what you notice and which district you are in. We agree a time that suits you, and you set aside water for household use while the tank supply is off. We go up to the tank and clean it from the inside, then watch what your tap water looks like afterwards and let us know.
These are the parts the cleaning goes through, depending on the tank's condition, its material and what you notice in your water.
- The lid and its seal
We check the lid and confirm it closes properly, because any gap is an entry point for dust, insects and birds that contaminate the water from above.
- The vent and its screen
Many tanks have a small vent with a mesh screen to keep insects out; we check its condition because a blocked or torn screen no longer does its job.
- The float and fill valve
The float controls when filling stops; we check that it moves freely and that the fill valve does not leak, since a leaking valve keeps water sitting at the wrong level.
- The inner walls
We scrub the walls to remove the slimy film and algae that form when the temperature rises inside a tank exposed to direct sun.
- The floor and sediment
Dust and sediment settle on the tank floor over time; we push them to the drain opening and rinse until the water runs clear.
- Outer shell and pipe openings
We inspect the pipe entry points for the fill and distribution lines and check for cracks that could let in contaminated water or hot air from outside.

Questions about Rooftop-tank cleaning
How do I know my rooftop tank needs cleaning?
Signs worth noticing include a change in water colour, an unusual smell or taste, sediment in the tap filter or at the bottom of a kettle. If the lid is cracked or does not close properly, or a long time has passed since the last clean, a check is a sensible step.
My rooftop tank lid is cracked, does that affect the water?
Yes, a lid that does not seal properly lets in the dust that blows across the rooftops, as well as insects and birds, all of which contaminate the water inside. Checking the lid and confirming it closes is part of the cleaning work, so tell us its condition when you call.
What should I prepare before rooftop-tank cleaning?
Store enough water for household use during the work and confirm that roof access is safe. If the tank is in a tight spot or the ladder or roof access is awkward, let us know when we agree the time so we can prepare accordingly.
There is a green tint in my rooftop tank water, what causes that?
A green tint is usually a sign of algae growing inside the tank. Rooftop tanks are exposed to direct sun and high temperatures, which make the walls and floor a suitable surface for algae to take hold. Cleaning covers scrubbing that layer off and rinsing until the water runs clear.
What affects the cost of rooftop-tank cleaning?
It depends on the tank's size and material, its condition inside, and how easy or difficult roof access is and where the tank sits on the roof. The cost is agreed after you explain what you need when you call or message us.
