Roof waterproofing in Rastanura: the local context
Rastanura is about 0.2 km from the sea coast (OpenStreetMap). Team note on Rastanura: 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..
Rastanura sits about 0.2 km from the sea coast, which is the first fact a technician should keep in mind when checking an apartment roof. Salt-laden air and coastal humidity can work into surface finishes and joints, so the first checks focus on the condition of the existing membrane at the parapets, drainage outlets and roof edges, where water tends to collect and where any earlier coating may have lifted. Crack lines in the screed and any bubbling or discolouration on the top floor ceilings are also worth noting before any material is chosen, because they show where water has already travelled.
Several things can only be settled on the site visit. The exact roof area, the slope and whether ponding occurs after rain, the age and type of any existing waterproofing, and whether the roof is accessible for rooftop water tanks or air-conditioning units all change the approach. The technician will also need to decide between a liquid roof system, a bitumen membrane or insulation boards, and that choice depends on how the roof is used and what the building structure can carry. Pricing ranges for these options are indicative only, and the final figure depends on the measurements taken on the day.
To help the technician, it is useful to have the building plan or a rough sketch of the roof, the number of apartments served by the roof, and a note of any previous repair work or leaks reported by residents. Access arrangements for the roof, including key holders and the times residents are not using the top floor, should also be confirmed in advance. Photographs of ceiling stains and of the roof surface taken after a rain shower give a clear picture of where water enters. With this information ready, the technician can arrive, inspect the roof and recommend a suitable system without delay.
In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
When do you need roof waterproofing?
These are the signs most often linked to roof waterproofing:
- Stains on the top-floor ceiling after rain

Where the problem usually comes from
- Damaged waterproofing around tank and AC bases.

- A common cause: cracks in the roof slab.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
From the first visit to the report
- Survey: Falls, drains and the condition of the old layer are recorded.
- Preparation: Cleaning and repairs before any new layer.
