Why roof tank leak detection differs in Al Aard

The centre of Al Aard is at 24.8935, 46.6060, about 21.2 km from the centre of Riyadh, with an approximate radius of 8 km. The approximate area shown on the map is centred here. Main roads in or near Al Aard: King Fahd Road, King Abdulaziz Road, Abu Bakr Al Siddiq Road.

The centre of Al Aard sits about 671 m above sea level (SRTM open elevation data). The nearest wadi channel is about 1 km from the centre of Al Aard (OpenStreetMap).

Roof water tanks on villas in Al Aard most often lose water through small leaks at the tank floor joints, the inlet and outlet fittings, and the float valve seals, rather than through the walls themselves. Owners usually notice a falling water level, a damp patch on the roof slab, or a pump that runs longer than it should. A good inspection starts by isolating the supply and watching the level over several hours, then checking each fitting and joint for seepage before deciding whether the problem is the tank, the pipework, or the valve.

Al Aard sits at roughly 671 m above sea level, about 21.2 km from the centre of Riyadh, and its centre lies at 24.8935, 46.6060. The nearest wadi channel is about 1 km from the centre of Al Aard, so rainfall can run quickly across the area during heavy storms. That makes the outlet and overflow arrangements worth checking carefully, because water movement around the roof and surrounding ground can expose weak seals and hidden seepage that a dry-season test might miss. The approach here therefore includes a check of the overflow path and the roof drainage, not only the tank itself. Where a tank interior has deteriorated, internal coating is priced at SAR 25–65 per m², so the detection stage matters: it tells you whether a coating repair is needed or whether a fitting replacement will solve the problem.

Before the visit, ask the provider whether the inspection includes a timed water-level test and a check of the overflow and float valve, and whether they will inspect the roof slab beneath the tank for damp. Ask how they will confirm the source of the leak rather than only estimating it, and whether the quote separates detection from any repair. Ask them to explain how a wadi-side site such as Al Aard affects the drainage they will check. Finally, confirm access to the roof and the tank in advance, and ask for the findings in writing so you can compare them with any later work.

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.
• A fibreglass or polyethylene tank cracking in the sun — we check this before anything else.
• Inlet and outlet connections — we check this before anything else.

How we choose the tool in Al Aard

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.
