How do you know if the water tank on your roof is leaking? For many owners in Al Aqyq, the first sign is a drop in water pressure, a damp patch on a ceiling, or a monthly water bill that climbs without explanation. Al Aqyq sits at about 24.7740, 46.6309, roughly 8.1 km from the centre of Riyadh, within an approximate radius of 2.8 km. The area's centre is about 647 m above sea level, which means rooftop tanks here are exposed to strong sun and dust, and the nearest wadi channel runs about 0.7 km from the centre, so dust and grit can reach roofs during storms. Both conditions can wear down tank walls, seams and fittings over time, so a leak can start unnoticed.

A leak check on a residential roof tank usually follows a clear sequence. The inspector first looks at the tank from the outside for cracks, rust tracks, wet staining and failed joints, then checks the inlet and outlet valves, float valve and overflow pipe for drips. Next, the water level is marked and the supply is watched over a set period to see whether the level falls when no taps are running, which is the classic sign of a leak. Where a tank wall or floor is suspect, the inspector checks the internal coating condition, since coating repair is priced per square metre, typically SAR 25–70 per m², depending on the work needed. The findings are then explained to the owner in plain terms, with options for repair, recoating or replacement.

Before the visit, gather a few details so the inspection can be completed in one trip. Note when you first noticed low pressure or damp patches, and whether the problem appears after the tank fills or between refills. Clear access to the roof and the tank lid, and make sure the water supply to the building is on so the level can be observed. If you have any previous repair records or the tank's age and material, have them ready. Keep taps and appliances off during the test window, and let the inspector know if anyone in the building has been using water at unusual times, as this can affect the reading.

For a residential building, shared risers, tanks and pumps are checked as one system.
