Before we start: what we know about Khafji

Main roads in or near Khafji: King Abdullah Road. Team note on Khafji: 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..

Khafji is about 2 km from the sea coast (OpenStreetMap). The centre of Khafji sits about 9 m above sea level (SRTM open elevation data).

Khafji sits on the Gulf coast in the Eastern Province, and its centre lies about 9 m above sea level. That modest height means rainwater on flat or low-pitched roofs tends to pool rather than run quickly toward outlets, so drains and gutters here need regular checking before the rainy months arrive. The town is also about 2 km from the sea coast, which places many homes within reach of salt-laden air. Salt residue can build up on roof surfaces and in outlet grates, slowly narrowing the flow path and corroding metal fittings, so inspections should look closely at both the membrane and the drainage hardware.

Each of these conditions changes how a service is planned. Because water settles on a low, near-level roof, a maintenance visit focuses on clearing outlets, checking falls toward drains, and identifying ponding spots before they damage the waterproofing. A typical maintenance visit costs SAR 150–400 per visit, and that range reflects the time needed to clear debris and test drainage. Where salt exposure has already worn the surface, restoration may be needed, priced at SAR 50–150 per m². Owners who schedule visits ahead of the wet season, rather than after leaks appear, usually find that the work stays limited to cleaning and minor sealing instead of larger repairs.

Several habits cause avoidable trouble in homes near the coast. Many owners wait for a visible leak before calling anyone, by which point water has already reached ceilings and insulation. Others wash roofs with high-pressure equipment, which can strip protective coatings and force debris into seams. Some ignore the gutters and outlet covers entirely, letting leaves and sand accumulate until the drains block during the first heavy rain. Finally, a few owners treat salt damage as cosmetic, overlooking the corrosion it causes in metal drain fittings. Avoiding these mistakes keeps both the roof and the drainage system working without interruption.

The aim is to locate the cause with instruments first, so any opening is limited to one point.
