Roof rain leak emergency in Yanbu: the local context

Yanbu is about 1.2 km from the sea coast (OpenStreetMap). The centre of Yanbu sits about 6 m above sea level (SRTM open elevation data).

Main roads in or near Yanbu: King Abdulaziz Road, Umluj Road, Al Hanan Street. Team note on Yanbu: 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..

When a school roof leaks in Yanbu, the first thing to check is where the water is coming from and how quickly it is spreading, because the town's location shapes what the roof has to cope with. The centre of Yanbu sits about 6 m above sea level, and the city is about 1.2 km from the sea coast. Both facts matter for a school roof, since a leak near classrooms, corridors or electrical fittings can spread quickly and needs to be contained before anything else is done. Staff should first move pupils and equipment away from the wet area, switch off power to any affected fittings, and place buckets or sheeting to protect floors and furniture.

Several things are left to the site visit, and they cannot be judged from the ground. The technician will need to see the roof surface, the condition of drainage outlets, the state of any parapet and flashing, and whether the leak comes from a crack, a failed joint or ponding water. The choice of repair material also depends on what is found: liquid roof waterproofing, a bitumen membrane, or insulation boards such as XPS are all used on roofs, but the right option is decided only after inspection. Nothing in this section should be read as a fixed quote or a promise of a particular method until the roof has been seen.

To help the technician arrive prepared, the school should note when the leak was first seen, whether it follows rainfall, and which rooms or ceilings are affected. Photographs of stains, cracks or damaged areas taken during and after rain are very useful. It also helps to know the roof's access route, any recent repair work, and the times when the school can be entered safely. Clear notes like these allow the visit to focus on the cause of the leak rather than on basic questions, which shortens the time pupils are kept away from the affected rooms.

For schools, the larger jobs are planned for weekends and holidays.
