Roof tank leak detection in Dammam: the local context

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

Dammam is about 4.3 km from the sea coast (OpenStreetMap).

Roof water tanks on rest houses and farms in Dammam most often fail quietly. A slow leak at a fitting, a cracked float valve, or a gap where the tank meets its stand can waste water for weeks before anyone sees a wet patch or a drop in pressure. On farms, the problem is often noticed only when the pump runs longer than usual or when irrigation lines run low. Our inspection starts by checking the overflow pipe, the inlet and outlet fittings, the float mechanism, and the base for staining, because these are the points where leaks usually begin on this property type.

Local conditions shape how we approach the job. The centre of Dammam sits about 12 m above sea level, so tanks there are typically fed by pumps rather than by gravity from a higher source, and pump cycling can hide small losses. The city is also about 4.3 km from the sea coast, which means salty air reaches many rooftops and speeds corrosion on metal fittings, brackets and tank surfaces. We therefore look closely at corroded connections and salt crusting near joints, and we note where a repair is likely to need a fresh coating rather than a simple patch. Where the inside of a tank has lost its protective layer, internal coating is quoted at SAR 25–60 per m², and the exact figure depends on the surface area we measure on site.

Before the visit, ask a few clear questions so the inspection can be planned properly. Tell us the tank material, its approximate size and age, whether it is on a rest house roof or a farm stand, and how it is filled, by pump or by another supply. Describe what you have noticed, such as damp walls, lower pressure, or a meter that keeps moving when no one is using water. Let us know whether the tank has been cleaned or recoated before and whether there is any access problem on the roof. These details help us bring the right tools and tell you clearly what the inspection will cover.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs worth paying attention to

If you notice one of these signs in Dammam, it is a good moment to talk to the team:

• Repeated spills from the overflow outlet
• Water on the roof around the tank base
• A stain on the top-floor ceiling

The most common causes

• A worn float valve.
• A fibreglass or polyethylene tank cracking in the sun — we check this before anything else.
• Inlet and outlet connections.

Tools we use in Dammam

The steps in order

1. Inspecting the base and connections: We look at where water gathers and trace it back.
2. Level test: The level is recorded with filling stopped.
3. Float and overflow check: We confirm whether water is escaping through the overflow rather than the tank body.
4. Recommendation: Repair of the connection, the float or the tank, stated in writing.
