Roof tank leak detection in Jeddah: before buying or handover
In short: Roof tank leak detection (before buying or handover) 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). Pricing starts from Inspection visit (SAR 150 per visit), and other items are quoted after the visit.
Before we start: what we know about Jeddah
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.. 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).
A typical owner in Jeddah who is buying a flat or villa, or taking over a property from a previous occupant, often has little idea what sits on the roof. The water tank may have been filled and forgotten for years, and any stains on the ceiling below might be blamed on rain rather than on a slow leak from the tank itself. Before signing or accepting the keys, it is worth checking the tank as carefully as the walls and wiring.
The local setting matters here. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data), and Jeddah is about 2 km from the sea coast (OpenStreetMap). Being close to the coast means the air is humid and salty, which can speed up corrosion on metal fittings, joints and unprotected surfaces. Because the city sits only a short distance above sea level, the elevation does not mean the roof is free from moisture problems; the damp, salty air still reaches rooftop equipment. For an owner, this means a tank that looks sound from a distance may have hidden wear at its seams and outlets, so a proper inspection is more useful than a quick glance.
Start by asking for the tank's history: when it was last cleaned, whether it has been repaired, and whether any leaks were reported before. Next, have the tank emptied or at least check the water level over a set period to see whether it drops unexpectedly. Inspect the internal surfaces for flaking, blistering or bare patches, and note that internal coating is usually priced at SAR 25–65 per m², so an accurate measurement of the tank's interior helps you understand the cost of any repair before you negotiate. Check the joints, valves and overflow pipe for rust or staining, and look at the ceiling below the roof for fresh marks. If you find a leak, get the source confirmed before agreeing who pays, and record everything in writing before completing the purchase or handover.
Before buying or taking over a property, an inspection gives you findings in writing before you sign.
When do you need roof tank leak detection?
If you notice one of these signs in Jeddah, it is a good moment to talk to the team:
- Repeated spills from the overflow outlet
- A stain on the top-floor ceiling
- Water on the roof around the tank base
Causes we see in the field
- A common cause: a worn float valve.
- A common cause: inlet and outlet connections.
- A fibreglass or polyethylene tank cracking in the sun — we check this before anything else.
Tools and methods, and when we use them
| Tool | What it finds | When we use it in Jeddah |
|---|---|---|
| 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 |
| Dye test | Water being drawn in at openings and cracks | Limits: only for visible, nearby points |
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.

Short answers for 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.
