Before we start: what we know about Qatif

Team note on Qatif: 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.. Qatif is about 2.5 km from the sea coast (OpenStreetMap).

The centre of Qatif sits about 5 m above sea level (SRTM open elevation data).

Qatif sits close to the Arabian Gulf, about 2.5 km from the sea coast, and its centre is only around 5 m above sea level. That combination shapes how rain behaves on residential roofs here. Water does not have much height to drain away, so flat and low-slope roofs can hold water for longer, and salty sea air settles on surfaces and slowly wears down sealants and membranes. When a leak appears after rain, it is worth assuming that water has already been sitting on the roof and seeping into the structure for some time.

Those local facts translate directly into how a repair is planned. Because the ground is low and close to the coast, the first step is usually to trace where water is pooling and entering, rather than only treating the visible stain below. Roof work is often matched to the surface: liquid roof waterproofing is commonly priced in the range of SAR 8–25 per m², bitumen membrane SAR 15–35 per m², and XPS boards SAR 12–30 per m², so the choice depends on the roof's condition, access and how much insulation is wanted. Where cracks are the source, crack injection is priced at SAR 40–120 per metre, and the length of the defect drives the scope and cost. Where a rooftop water tank contributes to the problem, tank internal coating runs SAR 25–60 per m², and the tank is best checked at the same visit.

Owners in Qatif often make the same avoidable mistakes. They patch the ceiling and repaint without finding the entry point, so the leak returns after the next storm. They leave ponding water in place instead of correcting the slope or clearing drains, which keeps the membrane under constant stress. They also treat a small crack as cosmetic and delay repair until moisture has spread into walls or a bathroom floor, where the work becomes larger. Asking for the affected area to be measured per square metre or per metre of crack before work starts makes the scope clear and helps you compare quotes on equal terms.

For a residential building, shared risers, tanks and pumps are checked as one system.
