Team note on Ahad Rafida: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins..

Picture a homeowner in Ahad Rafida who notices a faint stain on the ceiling of a top-floor room and a dull patch on the rooftop where water pools after rain. The rooftop water tank sits nearby, and the owner has never looked inside it. Like many residents, they assume the building is sound until a leak shows up inside the living space, often after the damage has already spread.

The centre of Ahad Rafida sits about 2055 m above sea level, which means the town gets a notable temperature swing between hot daytime sun and cooler nights. Those daily changes make roof surfaces and rooftop tanks expand and contract, opening hairline cracks that let water in. Heavy rain arriving after a dry spell can also push water into weakened seams quickly. For a property owner, this means waterproofing is best checked before summer heat peaks and again before the rainy season, not after the first leak appears.

Start by inspecting the roof and the tank together. Look for cracks, lifted edges and ponding water on the roof surface, and check the tank's inner walls and seams for flaking or damp patches. Mark each problem area and measure it, since costs in this area are usually quoted per square metre for surfaces and per metre for cracks. Next, decide the repair method that fits each area: liquid roof waterproofing typically runs SAR 8–25 per m², a bitumen membrane SAR 15–35 per m², and XPS boards SAR 12–30 per m² where insulation is also wanted. Crack injection is priced at SAR 40–120 per metre. Then address the tank interior, where tank internal coating runs SAR 25–60 per m², and finish by checking that any basement or bathroom areas below are sealed too, with basement waterproofing at SAR 50–150 per m² and bathroom waterproofing at SAR 15–40 per m². Schedule the work so coatings can cure fully before the hottest weeks or the first heavy rain.

Checks before summer and before the rain season catch problems while they are still small.
