Roof water tanks on villas are one of the most common sources of hidden leaks in this part of Riyadh. Because the tank sits on the roof, a leak often shows up first as damp patches on the top floor ceilings or stains on the upper walls rather than as a visible puddle. Water loss can continue for a long time before anyone notices, since the tank refills from the network and the level looks normal. A good leak check therefore starts with the tank itself, the inlet and outlet fittings, the float valve, and the joints where pipes pass through the roof slab.

Al Nsym Al Shrqy is a residential area at 24.7378, 46.8406, about 16.9 km from the centre of Riyadh, with an approximate radius of 1.2 km. It sits about 581 m above sea level, and the nearest wadi channel is about 1.5 km from its centre. For roof tanks, this matters because the combination of heat, dust and occasional heavy rain puts stress on sealants and tank linings, so the leak is often in the coating or at a fitting rather than in the tank wall. The wadi nearby also means that water runoff from storms can move across roofs and wash debris into overflow lines, so the check should include the overflow pipe and drain outlets. Technicians working in the area should expect to inspect both the tank and the roof surface, not just the plumbing inside the villa.

Before the visit, ask whether the tank will be inspected from inside and whether the internal coating condition will be assessed. If recoating is needed, ask for the price per square metre; the tank internal coating rate is SAR 25–65 per m², so you can check any quote against that range. Ask how long the leak check is expected to take, which fittings will be tested, and whether the roof-level pipework and overflow outlet are included. Confirm that the visit will cover the villa's roof tank as a whole and not just the visible leak point, so the cause is found rather than just the symptom.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.

Signs that call for roof tank leak detection

The following signs are worth checking before they grow:

• 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 common cause: a fibreglass or polyethylene tank cracking in the sun.
• 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.
