Does a rooftop water tank at a hotel or serviced apartment really need waterproofing, and what will it cost? The short answer is yes, and the price depends on what is wrong and how much surface is involved. Water tank work is part of a wider set of services, and the figures below show how the costs break down. Internal coating of a tank is priced at SAR 25–65 per m², while epoxy coating, which is often used on surfaces that need a tougher finish, runs from SAR 35–95 per m². Cracks in the tank walls are handled separately by crack injection at SAR 40–125 per m. Because Riyadh's centre sits about 637 m above sea level, a tank on a building there is exposed to the dry, hot climate of the central plateau, which makes a sealed, well-maintained surface all the more important.
Before any work starts, the property owner should expect a site inspection that looks at the tank as a whole rather than only the visible surface. The inspector typically walks the tank interior, checks the walls and floor for cracks, flaking coating and damp patches, and notes where water is getting through. The inspection also records the areas of the tank and the roof around it, so that a quote can be built from measured square metres and linear metres of cracking. Where the tank sits on or near the roof, liquid roof waterproofing at SAR 10–25 per m² and bitumen membrane at SAR 15–35 per m² may be part of the same visit, since leaks often start at the roof junction and travel down. The inspector then explains which treatments suit the findings and gives a priced scope for each.
To make the visit efficient, the owner should prepare a few things in advance. Clear access to the tank hatch and the roof is essential, and the tank should be drained and cleaned as far as possible so the inspector can see the surface. Any previous repair records, invoices or warranty papers for the tank and roof should be gathered and shared, as they show what has been done before and help avoid repeating work. It also helps to note when leaks were first seen, where they appear in the building, and whether they are worse after rain or during periods of high use. Finally, the owner should confirm who will be on site to approve the scope, so that decisions about treatment and budget can be made during the visit rather than delayed.
For hotels and serviced apartments, rooms are handled in batches to keep units available.

Tools we use in Riyadh
| Method | What it helps with | Its role in Riyadh |
|---|---|---|
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Fill test with level monitoring | Whether a tank coating holds after the work | Limits: takes time to monitor the level |
| Crack injection (polyurethane or epoxy) | Stopping active water through cracks | Limits: treats the crack, not the water source |
The steps in order
- Emptying and ventilation: The tank is emptied and ventilated before entry.
- Cleaning and preparation: Loose material is removed down to a sound surface.
- Crack treatment: Active cracks are treated first.
- Coating layers: A material intended for drinking-water tanks is applied.
- Disinfection and fill test: The tank is disinfected and the level is monitored after filling.

Short answers for Riyadh
What is the best thermal insulation material for a humid climate in the Eastern Province?
In humid areas, it is preferable to choose materials with low water absorption, such as extruded polystyrene or polyurethane foam, because they retain their efficiency in the presence of moisture. However, the final choice depends on the type of surface, the budget, and the contractor's recommendation after inspection.
What is the drying time for the floor before use?
The drying time varies depending on the system type, layer thickness, and site temperature. The installer will specify it within the scope of work.
Does detecting bathroom leaks require breaking tiles?
Usually not. Modern tools such as thermal cameras, electronic listening devices, and pressure testing pinpoint the source of a leak with high accuracy. If breaking is necessary, it is limited to the repair point only, after the location has been confirmed.

Planning the visit in Riyadh
- 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.
