Roof tank leak detection for rest houses & farms in Jeddah

Before we start: what we know about Jeddah

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..

Roof tank leak detection in Jeddah serves rest houses and farms spread across a city where the land rises gently from the coast. The centre of Jeddah sits about 15 m above sea level, so many roof tanks are placed on buildings that are not especially high above the ground, and water pressure at taps can vary from one property to the next. Jeddah is also about 2 km from the sea coast, which means the air carries salt and humidity that can slowly attack metal fittings, seals and the outer surfaces of tanks. Our inspections start with these conditions in mind, checking joints, overflow pipes and float valves where salt and damp usually cause the first signs of trouble.

Each of these local facts has a direct effect on how we work. The modest elevation means that a small drop in tank level or a slow trickle at an overflow can be a real loss for a household or farm that depends on a steady supply, so we look at water levels over time rather than only at a single moment. The short distance to the coast means corrosion can start on fittings much sooner than in drier inland areas, so we pay close attention to galvanised steel, plastic connections and the lids that keep out dust and insects. For tanks that need protection, the internal coating is priced at SAR 25–65 per m², and the final figure depends on the tank's surface area and its condition. We explain the options clearly before any work begins, so the owner knows exactly what is being done and why.

Owners of rest houses and farms in Jeddah often avoid the same costly errors when they plan their water systems. A common mistake is waiting until a stain appears on a ceiling before checking the tank, when the leak may have been running for weeks. Another is ignoring a faint smell or a slightly lower water level, which can point to a failing seal long before any visible damage. Some owners also replace a single fitting while leaving corroded neighbours in place, so the problem returns within a short time. Regular checks on the roof, careful attention to overflow pipes and early repair of small defects are the habits that keep water flowing reliably and protect the building below.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

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

Where the problem usually comes from

• Inlet and outlet connections.
• A common cause: a fibreglass or polyethylene tank cracking in the sun.
• A common cause: a worn float valve.

Tools and methods, and when we use them

The steps in order

1. Inspecting the base and connections: We look at where water gathers and trace it back.
2. Level test: The level is recorded with filling stopped.
3. Float and overflow check: We confirm whether water is escaping through the overflow rather than the tank body.
4. Recommendation: Repair of the connection, the float or the tank, stated in writing.
