A roof water tank is easy to forget until something goes wrong. Picture a villa owner in Al Yasmyn who notices a damp patch on the ceiling below the roof, or hears water dripping in the stairwell after a night of wind. The tank sits up top, out of sight, and the first sign of a leak is often a stain, a rising water bill, or a sudden drop in pressure at the taps. The same worry applies to the owner of an apartment building, where a leak from a shared roof tank can reach several floors at once.

Al Yasmyn is a district of about 3.7 km radius, located roughly 12.2 km from the centre of Riyadh, and its centre sits about 655 m above sea level. Its mix of villas and apartment buildings means that roof tanks are common, and a leak here affects more than one household. The nearest wadi channel lies about 2.1 km from the centre, so flash rain and runoff are part of the local picture. A tank that has been weakened by heat or left unchecked can be pushed harder by a storm, which makes early checks more important than they might seem on a quiet day.

For an emergency, work through the steps in order. First, shut the inlet and outlet valves to the tank if you can reach them safely, and turn off the pump so it does not run dry or keep feeding a leak. Second, move any furniture, electrical items and stored goods away from the wet area, and switch off power to affected circuits if water is near sockets or fittings. Third, place buckets or towels to limit damage and photograph the stain or the leak point for your records. Fourth, check whether the leak is from the tank body, the connections or the overflow pipe, since each points to a different repair. Fifth, arrange for a qualified technician to inspect the tank and, where the internal coating has failed, to price the recoating work, which typically falls in the range of SAR 25–65 per m². Finally, keep a note of when the problem started and what you did, so the repair can be matched to the damage.

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

Signs worth paying attention to

These are the signs most often linked to roof tank leak detection:

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

Causes we see in the field

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

Tools and methods, and when we use them

How the work is done, step by step

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.
