Roof water tanks are the quiet source of most leak complaints at hotels and serviced apartments in Al Sfarat. Guests rarely see the tank itself, so the first sign is usually a damp ceiling on the top floor, a stain spreading across a corridor, or a drop in water pressure that staff struggle to explain. By the time a leak reaches the rooms, the problem has often been running for weeks. Leak detection for these buildings starts with the tank and its fittings: the lid seals, inlet and overflow pipes, float valves, and the joints where the tank meets the roof slab. Checking these first saves time and avoids opening walls unnecessarily.

Al Sfarat sits at about 656 m above sea level, with its centre at 24.6806, 46.6240, roughly 6.4 km from the centre of Riyadh. The nearest wadi channel runs about 1.2 km from the centre, so rainfall runoff and occasional flash flows can reach low-lying parts of the area quickly. For a roof tank, this means that external water can sometimes be mistaken for internal leakage. A technician working here should separate the two by checking the tank level over a set period with the supply isolated, and by inspecting the roof drainage and parapet flashing for signs of water entering from outside. Where a building sits in the ground-level path of runoff, its ground-floor plant room and any tank overflow outlets need closer attention after heavy rain.

Before the visit, ask the provider a few direct questions. Ask whether they will test the tank with the supply closed to confirm the source of loss, and whether they will check the overflow pipe and float valve as part of the inspection. Ask how they distinguish a tank leak from roof runoff in an area near a wadi channel. If repairs are likely, ask for the cost of internal coating, which is quoted at SAR 25–70 per m², and confirm how the tank area will be measured. Finally, ask who will be on site, how guests and staff will be kept informed, and whether the report will include photographs of the affected areas and the tank condition.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

Signs worth paying attention to

If you notice one of these signs in Al Sfarat, it is a good moment to talk to the team:

• Repeated spills from the overflow outlet
• A stain on the top-floor ceiling
• Water on the roof around the tank base

The most common causes

• A common cause: a worn float valve.
• Inlet and outlet connections.
• A fibreglass or polyethylene tank cracking in the sun — we check this before anything else.

How we choose the tool in Al Sfarat

The steps in order

1. Inspecting the base and connections: We look at where water gathers and trace it back.
2. Level test: The level is recorded with filling stopped.
3. Float and overflow check: We confirm whether water is escaping through the overflow rather than the tank body.
4. Recommendation: Repair of the connection, the float or the tank, stated in writing.
