Roof rain leak emergency for schools in Abu Arish

Before we start: what we know about Abu Arish

Team note on Abu Arish: 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.. The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data).

Abu Arish sits about 67 m above sea level, a fact that matters little for the first check but shapes how water moves off a flat school roof during heavy rain. Before anything else, the technician should confirm where the water is entering: a stain on a classroom ceiling can come from a roof membrane, a parapet joint, a drainage outlet, or a crack that has opened near a rooftop water tank. Each source points to a different repair, so the first step is to trace the path from the wet area upward. Staff should also be asked whether the leak appears only in heavy rain or whenever it rains, because that answer narrows the likely cause quickly.

Several things are left to the site visit, because they cannot be judged from a description. The technician needs to see the roof surface, check whether ponding water is standing for hours after rain, inspect each drain and outlet for blockage, and measure the affected area so an accurate quote can be prepared. Repair methods also depend on what is found: a short crack may suit crack injection at SAR 40–120 per metre, while a worn roof surface may be better treated with liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m². Epoxy coating at SAR 35–90 per m² and spray foam at SAR 20–45 per m² are options only once the surface condition is known. Basement, bathroom and tank work are outside a roof leak call unless the water source proves to be linked to them.

To help the technician arrive prepared, the school should share the building's age, any previous roof repairs, and the dates when leaks were noticed. Photographs of the stains taken during and after rain are very useful, as are notes on whether a rooftop tank sits close to the leak. Access arrangements matter in a working school, so the school should confirm which roof hatches are usable, when classes are in session, and who will meet the technician on arrival. Clear information at the start saves time, keeps students away from unsafe areas, and lets the repair be scoped correctly on the first visit.

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

Signs worth paying attention to

The following signs are worth checking before they grow:

• A stain growing on the top-floor ceiling
• Water standing on the roof that does not drain
• Drips from the ceiling during rain

The most common causes

• Damaged waterproofing at the edges.
• A blocked roof drain.
• A common cause: a split in the waterproofing around a tank or AC base.

Tools and methods, and when we use them

The steps in order

1. Protect what is below: Move belongings and contain the water first.
2. Drain the roof: Clear the roof drains so water can leave.
3. Inspection after the rain stops: The entry point is found on a dry roof.
4. Treatment: A local repair or a waterproofing plan, as the inspection shows.
