Roof tank leak detection in Jeddah: without breaking
In short: In Jeddah (Jeddah), roof tank leak detection (without breaking) begins with the documented tank level test and the moisture meter; nothing is opened until the position is clear. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data). Published price: Inspection visit, SAR 150 per visit; anything else is quoted after the inspection.

Roof tank leak detection in Jeddah starts with the location of the building itself. The centre of Jeddah sits about 15 m above sea level, and the city is about 2 km from the sea coast. Because of this, a technician checks the rooftop tank and its connections with the building's elevation and exposure in mind, looking first at the roof-mounted fittings, the overflow pipe, and the tank base where water pressure and corrosion tend to show first. These are the places where a leak is easiest to confirm without opening anything up, so they are the first points on the checklist.
Some things cannot be judged from the ground or from a description, and they are left to the site visit. The technician must see the actual condition of the tank walls, the seals around inlet and outlet valves, the float valve action, and any staining or salt deposits on the surfaces. The tank's internal coating is also assessed on site, since coating work is priced per square metre, typically SAR 25–65 per m², and the area can only be measured once the tank is accessible. Any decision about repair, recoating, or replacement waits until these checks are complete, so the homeowner receives a clear picture before work begins.
Information that helps the technician makes the visit faster and more accurate. Note when the leak was first noticed, whether the water loss is constant or only appears when the tank is full, and whether the building's ceilings or walls show damp patches below the tank position. Share the age of the tank, the material it is made from, and any previous repairs or coating work. Clear access to the roof and the water supply valves also helps, because the technician can then test each section without delay. With these details in hand, the visit can focus on the likely source of the leak, keeping disruption to the household to a minimum.
The aim is to locate the cause with instruments first, so any opening is limited to one point.
Signs that call for roof tank leak detection
If you notice one of these signs in Jeddah, it is a good moment to talk to the team:
- Water on the roof around the tank base
- A stain on the top-floor ceiling
- Repeated spills from the overflow outlet
Where the problem usually comes from
- A fibreglass or polyethylene tank cracking in the sun — we check this before anything else.
- Inlet and outlet connections.
- A common cause: a worn float valve.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Dye test | Water being drawn in at openings and cracks | Limits: only for visible, nearby points |
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
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.

Questions from 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.
What is the first step of roof tank leak detection (without breaking)?
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).
How much 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 get at the end?
The source of the water identified: tank body, connections or float valve, in a technical report that carries a verification code.
What we advise against
- Mistaking a float overflow for a leak in the tank body
What you receive
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
- 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.
- 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.
