Before we start: what we know about Jubail

Team note on Jubail: 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.. Jubail is about 0.9 km from the sea coast (OpenStreetMap).

The centre of Jubail sits about 4 m above sea level (SRTM open elevation data).

Is a rain leak from the roof of an apartment in Jubail something that can wait until the weather clears? In most cases it cannot. Jubail's centre sits about 4 m above sea level (SRTM open elevation data), and the city is about 0.9 km from the sea coast (OpenStreetMap). Water that enters through a roof slab in this coastal setting can spread into the ceiling and walls of the flat below, so it is worth acting quickly. Roof waterproofing for a flat is usually priced per square metre, with liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m². Those figures give an owner a starting point, but the final cost depends on what the inspection finds.

The inspection begins with the roof surface itself, looking for cracks, lifted membrane edges, blocked drains and pooled water. Where a crack runs along the slab, crack injection is priced at SAR 40–120 per metre, so the length of the crack found on site matters a great deal to the quote. The inspector will also check the parapet, the joints around the rooftop water tank and any pipe penetrations, since these are common entry points. Once the source is traced, the team can recommend a method suited to the damage, whether that is a fresh liquid layer, a bitumen membrane, or a repair to a single line of cracking. Where the leak has reached the apartment below, the inspector may also look at the bathroom above, where bathroom waterproofing is priced at SAR 15–40 per m².

Before the visit, it helps to prepare a few things. Move furniture and valuables away from ceilings and walls under the leak, and place buckets or towels to catch dripping water. Take clear photographs of the stains and the roof area showing any visible cracks, and note when the leak appears, whether during rain, after it, or from a specific wall. If there is a water tank on the roof, make sure access is clear so the inspector can reach its base and surrounding joints. Having the property deed or the building's maintenance contact ready also speeds up the process. With this information to hand, the inspection can focus quickly on the true source of the leak.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
