Is a leaking roof water tank costing your hotel or serviced apartment building more than you think? Many owners in Jeddah only notice a problem when a guest complains of low pressure, damp ceilings or a musty smell on the top floor. In a city where the centre of Jeddah sits about 15 m above sea level, rooftop tanks often serve the upper floors directly, so even a small leak can quickly affect guest comfort and the building below. Because Jeddah is about 2 km from the sea coast, the salty, humid air can also speed up corrosion on tank walls, fittings and seams, which makes regular checks more important than many owners expect.
Our inspection starts with a visual check of the tank exterior, lid, overflow pipe, inlet and outlet connections, and the support structure on the roof. The technician then examines the internal walls and floor for cracks, flaking coating and signs of water staining. Where needed, the team looks at the connecting pipework and valves to find out whether water is escaping from the tank or from the supply line. If the internal coating is worn, we explain the likely repair scope and the cost range, which is SAR 25–65 per m² for tank internal coating, so you can plan the work with clear figures before anything begins. Findings are shown to you on site, with photographs where useful, so you understand what has been found and why.
Before the visit, please gather a few details that help us work efficiently. Note the approximate tank capacity, the age of the tank if known, and any past repairs or coating work. Tell us which floors the tank supplies and whether guests have reported low pressure, damp patches or staining in ceilings. Make sure access to the roof is clear and that someone who knows the building's water layout is available to answer questions. If the tank is in use during the visit, let guests and staff know in advance so that water supply interruptions are planned around occupancy and daily routines.
For hotels and serviced apartments, rooms are handled in batches to keep units available.
Signs worth paying attention to
The following signs are worth checking before they grow:
- Water on the roof around the tank base
- A stain on the top-floor ceiling
- Repeated spills from the overflow outlet
The most common causes
- A fibreglass or polyethylene tank cracking in the sun — we check this before anything else.
- Inlet and outlet connections — we check this before anything else.
- A worn float valve — we check this before anything else.
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 |
| 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 |
The steps in order
- 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.
What is the first step of roof tank leak detection for hotels & serviced apartments?
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).

If you live in Jeddah and are new to the area
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- 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).
