We inspect the roof and the tank together
We check the condition of the roof slab, the joints, the edges and the parapet, then the tank base and its outer walls, because each affects the other.
- 3
We waterproof the roof first
The roof slab is prepared and the cracks, joints and drains are treated, then the waterproofing layer is applied across the full area including the zone around the tank base.
- 4
We treat the tank on a finished roof
Once the roof is ready we waterproof the tank base and its outer walls, so both layers work together and neither undoes what the other seals.
One treatment instead of two
- The tank and the roof are treated together in one complete job
- The order of the work stops one waterproofing layer from damaging the other
- We waterproof and thermally insulate according to each surface's condition
- We take your request by phone call or WhatsApp message
- Cost depends on the case, message us to work it out together
The service in Al Jishshah
In a district like Al Jishshah, the tank usually stands on a base set into the flat roof, and damp often shows under the tank base or around its pipes. Heat from the tank transfers to the roof and ceiling below during summer. The tank is checked for base integrity, joints and cracks around pipes, and the roof is checked for damp or cracks beneath the tank. The tank exterior and base are then insulated with foam or bitumen, and the surrounding roof is insulated.
Al Jishshah is a district in Al-Ahsa governorate in the Eastern Province, close to Al Markaz, Al Jafr and As Sabat.
The tank base is the weakest point in the system, because water gathers around it and heat concentrates on it.

Questions about Tanks & roofs together in Al Jishshah
Yes, if the roof slab is sound and the joints and drains are tight, treating the tank alone is enough. But if the roof has cracks or signs of damp, ignoring it means water will find a way through even after the tank is sealed. That is why we check both before deciding.
They suit the roof's condition and what it needs. Bitumen rolls are laid over open areas and the edges and joints are sealed. Epoxy suits the finish around the tank base and at the drains. Polyurethane foam may be added for thermal insulation where the roof is exposed to direct sun.
The tank base sits directly on the roof slab, and any water that leaks from under the tank stops only where the waterproofing ends. If the slab is bare or has an old worn layer, the water soaks into it and reaches the floor below. Over time the slab itself cracks under the accumulated moisture.
If the stain is concentrated directly below the tank, the tank is likely the cause. If it spreads across a wider area of the ceiling, the roof is the more likely source. But the two often work together to bring water to the same place, so inspection alone tells them apart with certainty.
Tell us whether the damp appears on the top-floor ceiling, on the roof surface around the tank, or both. Tell us whether the tank is concrete or fibreglass and whether water appears under its base. These details tell us where to start and which materials suit the situation.
Yes, hot water in the tank and sun-exposed metal raise the temperature of roof and ceiling, especially in rooms near the tank. Thermal insulation of both tank and roof together reduces this effect significantly.
Mention the tank size roughly, whether you see damp or dark stains on the ceiling below it, whether rooms near it get very hot, and send a photo of the tank and base if you can.
