Bitumen membrane in Aldarb: the local context
Aldarb is about 18.7 km from the sea coast (OpenStreetMap). The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data).
A homeowner in Aldarb who notices damp patches on a flat concrete roof, or who is planning to re-waterproof a terrace before the rainy season, is typically trying to balance cost against the long-term protection of the building below. Bitumen membrane is one of the common options for this kind of surface, and comparing its published range with other systems helps set realistic expectations before any work is booked.
The local facts shape that decision. Aldarb sits roughly 79 metres above sea level and about 18.7 km inland from the coast, so it is not a low-lying site where standing water tends to gather at ground level. For a roof, that means the main concern is water running off and pooling on the surface itself rather than rising from below. Bitumen membrane is published at SAR 15–35 per m², which places it in the middle of the range when set alongside liquid roof waterproofing at SAR 8–25 per m² and spray foam at SAR 20–45 per m². A lower figure does not automatically mean a better choice, so the owner should compare the condition of the existing roof surface and the extent of any cracks before choosing a system.
Practical steps can keep the process orderly. First, measure the roof area in square metres so the published range can be applied to the real size of the job. Second, inspect the surface for cracks and note their total length in metres, since crack injection is priced separately at SAR 40–120 per metre and may be needed before any membrane is laid. Third, decide whether the roof is accessible for a single full covering or whether sections need to be treated in stages. Fourth, request written quotes from more than one provider and check that each one states the scope, the material type and whether surface preparation is included. Finally, confirm the warranty terms in writing before work starts, and keep records of the completed job for future maintenance.
