Roof tank leak detection for restaurants in Al Mnswra, Riyadh starts with the location itself. The centre of Al Mnswra sits at 24.6089, 46.7451, about 13.6 km from the centre of Riyadh, with an approximate radius of 1.2 km. Because the area is roughly 584 m above sea level, rooftop tanks here are exposed to strong sun and wide daily temperature swings, so the first checks focus on the tank lid, seams, fittings and the sun-facing side of the tank where expansion and cracking are most likely. The nearest wadi channel is about 2.8 km from the centre of Al Mnswra, which means seasonal runoff is not usually the first suspect, so the initial inspection looks at the tank body and connections before anything else.

The finer work is left to the site visit. The technician will confirm whether the leak is in the tank shell, a valve, a float or a pipe joint, and will check the internal coating condition on the tank walls. Coating repair is priced per square metre, typically in the range of SAR 25–70 per m², and the actual figure depends on the surface area measured on site and the condition of the existing lining. Water levels, pump runtime and any visible staining will be recorded during the visit, and the technician will decide whether repair or replacement is the more sensible route for the restaurant.

To help the technician arrive prepared, please note how long the leak has been noticed, whether the tank level drops overnight or only at peak service, and when the tank was last cleaned or recoated. Clear access to the roof, the tank lid and the plant room will save time. Please also share the restaurant's opening hours so the visit can be scheduled when kitchen water use is low and the team can test the system properly.

For restaurants, visits are planned outside service hours and recorded for the premises file.

Signs worth paying attention to

Tools and methods, and when we use them

The steps in order
