Roof tank leak detection in Jeddah: preventive periodic check
In short: Roof tank leak detection (preventive periodic check) in Jeddah starts with the documented tank level test, then the moisture meter, before anything is opened. Jeddah is about 2 km from the sea coast (OpenStreetMap). Published price: Inspection visit, SAR 150 per visit; anything else is quoted after the inspection.
Roof tank leak detection in Jeddah: the local context
Jeddah is about 2 km from the sea coast (OpenStreetMap). The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data).
Team note on Jeddah: 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 first thing a technician checks on a roof tank in Jeddah is the tank's position and the way water reaches it. The centre of Jeddah sits about 15 m above sea level, according to SRTM open elevation data, and the city is about 2 km from the sea coast, based on OpenStreetMap. Those two facts matter because a roof tank here sits in a coastal, low-lying setting where salt-laden air and warm daytime temperatures can work on steel, joints and fittings. Because of this, the visit begins at the outside of the tank and its supports, looking for corrosion, weeping seams and loose connections before the inside is touched.
Several things are left to the site visit itself, because they cannot be judged from a distance or from a general rule. The technician looks at the actual condition of the tank wall, the lid, the overflow pipe, the float valve and the inlet and outlet fittings. The state of any existing internal coating is also judged on the spot. Where a coating has broken down, the cost of re-coating is a matter for the quote, and the internal coating rate is SAR 25–65 per m², so the final figure depends on the measured area and the condition found. Nothing in this page replaces that inspection.
Information that helps the technician makes the visit faster and more accurate. It is useful to know how old the tank is, when it was last cleaned, whether there has been any noticeable drop in water level, damp patches on the roof or walls below, or a taste or colour change in the water. Please also point out where the tank sits, whether it is on a rooftop, a slab or a frame, and whether there is safe access to the lid. Clear answers to these points let the technician focus on likely leak paths and give you a more reliable picture of the tank's condition.
Preventive checks follow a written schedule instead of waiting for a fault.
When do you need roof tank leak detection?
The following signs are worth checking before they grow:
- A stain on the top-floor ceiling
- Water on the roof around the tank base
- Repeated spills from the overflow outlet
The most common causes
- A common cause: inlet and outlet connections.
- A fibreglass or polyethylene tank cracking in the sun — we check this before anything else.
- A worn float valve.
Tools we use in Jeddah
| Method | What it helps with | Its role in Jeddah |
|---|---|---|
| Dye test | Water being drawn in at openings and cracks | Limits: only for visible, nearby points |
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
How the work is done, step by step
- Inspecting the base and connections: We look at where water gathers and trace it back.
- Level test: The level is recorded with filling stopped.
- Float and overflow check: We confirm whether water is escaping through the overflow rather than the tank body.
- Recommendation: Repair of the connection, the float or the tank, stated in writing.

Common questions about roof tank leak detection in Jeddah
Can I use household chemicals instead of calling a technician?
Using unsuitable chemicals may corrode pipes and does not fix the root cause of the blockage, so it is better to rely on a specialist technician.
What is the difference between foam insulation and other types of insulation?
Foam insulation is easy to apply on uneven surfaces and forms one continuous layer with no joints, while other types, such as bitumen rolls, need the joints to be welded. The contractor decides which is most suitable after inspecting the site.
Can thermal insulation be applied to an existing building?
Yes, thermal insulation can be installed on the roofs and walls of existing buildings without the need for major structural modifications. The contractor prepares the surface, then applies the insulating material and the protective layer over it.
Where does roof tank leak detection (preventive periodic check) start in Jeddah?
We start with inspecting the base and connections (we look at where water gathers and trace it back), then level test (the level is recorded with filling stopped).
What does roof tank leak detection cost in Jeddah?
From our published price list: Inspection visit SAR 150 per visit. Quantities are confirmed at the inspection.
What do I receive after the work?
The source of the water identified: tank body, connections or float valve, in a technical report that carries a verification code.
Common mistakes we see
- Mistaking a float overflow for a leak in the tank body
The written outputs
You receive: the source of the water identified: tank body, connections or float valve, in a technical report with a verification code.
Planning the visit in Jeddah
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
