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 service-area circle on the map below is drawn from this point. The centre of Al Aard sits about 671 m above sea level (SRTM open elevation data).

Roof leaks in villas are the most common problem we see in Al Aard, and they usually start small: hairline cracks in the parapet, lifted edges where the membrane meets a wall, or ponding water near drains that has slowly softened the surface. By the time staining reaches a ceiling, water has often been travelling through the roof structure for a long time. For this property type, the first job is to find where water actually enters, not simply to coat the whole surface.

The local setting shapes the approach. Al Aard sits at about 671 m above sea level, and its centre lies roughly 21.2 km from the centre of Riyadh, within an approximate radius of 8 km. The nearest wadi channel is about 1 km from the centre of Al Aard, so during heavy rain, runoff can arrive quickly and in volume. That makes drainage outlets, roof falls and the junctions around rooftop water tanks especially important. For many villas, a liquid roof waterproofing system or a bitumen membrane may suit the main roof, while crack injection is often needed for individual defects in walls or slabs. Where a tank sits on the roof, its internal coating is worth checking at the same visit, since the two problems are often linked.

Before the visit, ask for a clear description of the leak's location and when it appears, whether after rain, after tank filling, or both. Ask for photographs of the roof surface, the parapets and any ceiling staining, and note the roof's age and any previous repairs. Request a written scope that separates each item, such as liquid roof waterproofing per m², crack injection per metre and tank internal coating per m², so you can compare the work against the price ranges quoted. Confirm access to the roof, whether the drains are clear, and who will remove loose old material. A precise scope at the start makes the final cost easier to understand and the repair far more likely to last.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.
