Before we start: what we know about Jubail

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).

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..

Roof and drain maintenance for schools in Jubail starts with the site's position. The centre of Jubail sits about 4 m above sea level, according to SRTM open elevation data, and the coast is about 0.9 km away, based on OpenStreetMap. Because the ground is low and the sea is close, technicians check first whether rainwater and any coastal moisture can collect around roof edges, gutters and outlets. A drain that looks clear from ground level may still hold standing water or salt residue that slows flow, so the first look is at the low points of each roof section and the outlets that serve them.

Some things can only be judged on the day. The condition of waterproofing membranes, the extent of any cracking or blistering, the slope of the roof and the exact route of downpipes depend on what is seen when the technician is on the roof. The same applies to fixings, flashing around rooftop units, and any signs that water has already reached ceilings or classrooms below. Costs also vary with the work found: a maintenance visit is typically SAR 150–400 per visit, while restoration is SAR 50–150 per m², so the scope of the restoration area is confirmed only after inspection.

For the technician, the most useful information is a clear list of the roof sections, their access routes and the times when the school can be entered without disrupting lessons. It helps to know which outlets have blocked before, where ponding has been reported after rain, and whether any part of the roof is used for equipment or storage. Please also mention any recent repairs and whether drawings of the drainage layout exist. With these details, the visit can focus on the places where Jubail's low ground and nearby coast are most likely to cause trouble.

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