Samtah sits about 61 m above sea level, and the centre of town is roughly 22.6 km from the coast. For apartment owners weighing a bitumen membrane, those two facts shape the first checks. Elevation and distance from the sea help set expectations about how the building is exposed to weather and moisture, so the technician starts by reviewing the building's position and its roof and wall exposure before any materials are chosen. Bitumen membrane is priced at SAR 15–35 per m² for this work, and that range is worth understanding before anything is ordered, since the final figure depends on what the surface actually needs.
Several things can only be settled at the site visit. The technician needs to walk the roof or terrace, look at the existing finish, and note any cracks, ponding areas, blisters, or lifted edges. The condition of drainage outlets and upstands, and whether the old layer can stay or must be removed, are judged on the spot. If the problem extends beyond the roof into areas such as a basement, a bathroom, or a water tank, that is confirmed in person too, because each of these uses a different system. Crack injection, for example, is priced per metre at SAR 40–120 per m and is only measured once the cracks have been found and traced. Nothing in this stage should be assumed from a description alone.
To help the technician prepare, it is useful to have a few details ready. Note which parts of the building leak, when the leaks appear, and whether they follow rain or occur in dry weather. Share any previous repair records, the age of the building, and access arrangements for the roof and for shared areas. Photographs of the affected ceilings and the roof surface are also helpful. With this information, the visit can focus on the real problem, the quotation can reflect the actual area and condition, and the apartment owners can make a clear decision about the scope of work.
In apartment buildings, the floor below is often where a leak shows first.

Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
The steps in order
- Preparation: Cleaning, priming and repairs.
- Torch welding: Overlaps are welded and checked.
- Details: Upstands, drains and bases.
- Protection and flood test: Protection is laid after a successful flood test.
