Before we start: what we know about Dammam

Team note on Dammam: 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.. Dammam is about 4.3 km from the sea coast (OpenStreetMap).

The centre of Dammam sits about 12 m above sea level (SRTM open elevation data).

A roof rain leak at a school usually starts where water finds a weak point in the roof covering: a split bitumen membrane, a cracked liquid coating at a drain outlet, or a gap where the roof meets a parapet wall or a rooftop unit. Because the leak often shows up first as a stain on a classroom ceiling, the visible damage can be far from where the water actually enters. In Dammam, a roof leak at a school is treated as an urgent problem, since wet ceilings and electrical fittings in occupied rooms can become a safety issue quickly.

The local setting shapes how we approach the repair. The centre of Dammam sits about 12 m above sea level (SRTM open elevation data), so standing water after heavy rain has to be drained off the roof through working outlets rather than left to pool. Dammam is also about 4.3 km from the sea coast (OpenStreetMap), so salt-laden air can accelerate wear on exposed membranes and metal fixings. For that reason we look closely at the condition of the surface and edges, not only the patch that has already leaked. Where the roof is a suitable candidate, a liquid roof waterproofing system priced at SAR 10–25 per m² or a bitumen membrane at SAR 15–35 per m² may be discussed, depending on what the inspection shows. Cracks in any concrete upstand can be treated with crack injection at SAR 40–120 per m. Costs for any work are always confirmed after inspection.

Before the visit, it helps to ask the school to tell us a few things. Note which rooms are affected, when the leak appears (during the rain, or hours afterwards), and whether there are any ceiling stains, peeling paint or damp walls. Ask whether the roof has been repaired before and by whom, and whether any rooftop equipment, such as air-conditioning units or water tanks, has been moved recently. If a water tank sits on the roof, its condition matters too, since tank internal coating is priced at SAR 25–60 per m². Having this information ready lets our team arrange the right inspection and avoid disruption to lessons.

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 — we check this before anything else.
• A blocked roof drain — we check this before anything else.
• A split in the waterproofing around a tank or AC base — we check this before anything else.

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.
