Roof tank leak detection in Al Aard, Riyadh, starts with the location itself. The centre of Al Aard sits at 24.8935, 46.6060, about 21.2 km from the centre of Riyadh, and the area has an approximate radius of 8 km. The centre of Al Aard sits about 671 m above sea level, according to SRTM open elevation data. Because the site is elevated and well away from the city core, a technician should first confirm how the tank is fed and how it is exposed to the sun and wind on the roof. The nearest wadi channel is about 1 km from the centre of Al Aard, according to OpenStreetMap, so the site visit should also note any signs of runoff, sediment or erosion near the tank base that could point to ground movement or moisture reaching the foundation.

Several points are left to the site visit itself, because they cannot be settled from a map. The technician will walk the roof and the tank shell, check the seams, inlet and outlet fittings, overflow pipe, ladder and access hatch, and look for staining, cracks or old repair patches. Water in the tank should be checked for level changes over a set period, and any pipe joints between the tank and the building should be tested for drips. Where the tank has an internal coating, the condition of that coating can only be judged by opening and inspecting the tank. If recoating is considered, the internal coating cost is quoted at SAR 25–70 per m², and the final figure depends on the surface area measured on site and the condition of the existing lining.

To help the technician, please have the following ready before the visit: the tank's age, material and approximate capacity; the date the leak was first noticed and where the water was seen; any past repairs or recoating work; the position of the tank on the roof relative to parapets and drainage outlets; and access arrangements for the roof and the tank interior. Note whether the building sits close to the wadi channel and whether heavy rain has caused flooding or standing water on the roof or around the base. Clear answers to these questions let the technician focus on the most likely leak points and reduce the time spent on the roof. Send photographs of visible damage if possible, and keep the water supply valves in their normal position until the inspection is complete so the leak can be observed under usual conditions.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
