Roof rain leak emergency for schools in Alwajh

Before we start: what we know about Alwajh

Alwajh is about 0.7 km from the sea coast (OpenStreetMap). The centre of Alwajh sits about 19 m above sea level (SRTM open elevation data).

Team note on Alwajh: 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..

Roof leaks at schools in Alwajh are checked first for salt and moisture exposure, because the centre of Alwajh sits about 19 m above sea level and the town is about 0.7 km from the sea coast. That closeness to the coast means the air carries salt and humidity, which can break down roof membranes and sealants faster than in inland towns. When a leak is reported during a school day, the technician begins by asking where the water appears, how long it has been coming through, and whether the ceiling or wall beneath has been damp for some time. These answers help separate a fresh breach from an older failure that has spread.

Some things can only be settled on the roof itself. The exact entry point of the water, whether a cracked membrane, a failed joint, a blocked outlet, or a damaged upstand, cannot be confirmed from the classroom below, so it is left to the site visit. The technician will also decide whether a temporary patch will hold until term-end works, or whether a full section needs resealing. Pricing depends on what is found, so the figures for each repair type, such as liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², or spray foam at SAR 20–45 per m², are only applied once the extent of the damage is measured.

To help the technician arrive prepared, the school should note the room or rooms affected, any stains or bubbling in the ceiling paint, and the date the first sign appeared. Photographs taken from inside the room, along with a rough note of where the roof access point is located, will save time. Tell the technician if the roof has recently been walked on, if equipment or stored items sit on it, and whether any drainage outlets have been cleared recently. Keeping the roof access door unlocked on the visit day and making a staff member available to show the area will let the work start without delay.

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