What should you do if you suspect your roof water tank is leaking in Al Hzm, Riyadh? Start by treating it as an emergency only if you can see water spreading through a ceiling, pooling on a roof slab, or if the tank level drops faster than normal. Al Hzm sits at about 24.5473, 46.6536, roughly 18.6 km from the centre of Riyadh, within an area of around 1.2 km radius. The centre of the district sits about 676 m above sea level, and the nearest wadi channel runs about 0.8 km from the centre, so rainwater and dust can collect in low spots around buildings. These local conditions are a reason to act quickly rather than wait for the leak to grow.

Our technician begins by checking the outside of the tank, the inlet and outlet pipes, the float valve, and the connections where the tank meets the roof and the supply lines. Next, the water level is observed over a set period with the supply isolated, so a real drop can be told apart from normal use. The interior is then inspected for cracks, flaking, or bare patches. If the inside coating is failing, the surface area is measured and a repair estimate is prepared at SAR 25–65 per m² for internal coating, so you know the cost range before any work starts. The technician will explain what was found in plain terms and show you the affected areas.

To make the visit faster, clear access to the roof and the tank lid, and let the technician know where the water is showing up inside the building. Keep a record of when you first noticed the leak and whether the water level has been dropping. Turn off the pump if you can do so safely, and place buckets or towels under any dripping ceiling to limit damage. Have your building access details and any previous repair records ready. Tell us whether the tank is steel, concrete, or fibreglass, since the method differs for each. These steps help the inspection find the source of the leak on the first visit.

If water is flowing, close the main valve first, then call or message with photos.
