Roof waterproofing for apartments in Aldarb
In short: In Aldarb (Aldarb), roof waterproofing for apartments begins with the roof, falls and drains survey and the moisture meter for ceilings and walls; nothing is opened until the position is clear. The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data). Published price: Liquid roof waterproofing (per m²), SAR 8–25 per m²; anything else is quoted after the inspection.
Roof waterproofing in Aldarb: the local context
The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data). Aldarb is about 18.7 km from the sea coast (OpenStreetMap).
Roof waterproofing work in Aldarb starts with the location itself. The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data), and the town is about 18.7 km from the sea coast (OpenStreetMap). Both facts shape how a roof is checked before any material is chosen. A roof at this elevation and distance from the coast is judged on its surface condition, drainage, and exposure, so the first checks focus on how water moves across the slab and where it can collect and sit.
Several things are left to the site visit, because they cannot be known from a distance. The technician needs to walk the roof and note the age and state of any existing membrane, the slope toward outlets, cracks at parapets and roof edges, and whether ponding appears after rain. The condition of the parapet flashing, the seal around rooftop units and pipes, and any signs of trapped moisture below the surface are also judged on arrival. Prices vary, so the final scope and cost depend on what the inspection finds. For reference, liquid roof waterproofing typically falls in the range of SAR 8–25 per m², bitumen membrane in SAR 15–35 per m², and XPS boards in SAR 12–30 per m², but the right system is confirmed only after the visit.
Information that helps the technician is worth gathering before the appointment. Ask the resident or building manager when leaks were last noticed, which flats are affected, and whether any previous repair was done on the roof. Note the number of apartments sharing the roof and any shared access rules. If the roof is also used for water storage, mention the tank, since tank internal coating is priced separately at SAR 25–60 per m². Clear answers to these points let the technician plan the visit efficiently and explain the options to residents in straightforward terms.
In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.

The steps in order
- Survey: Falls, drains and the condition of the old layer are recorded.
- Preparation: Cleaning and repairs before any new layer.
- Primer: The base coat that the system needs.
- Waterproofing layers and details: Corners, upstands and bases get their own detail.
