Bitumen membrane work for apartments in Khamis Mushait most often deals with leaks through flat roofs and terraces, where water sits on the surface and finds its way into the top-floor ceilings and walls below. In many apartment blocks the roof is shared, so a single failing section can affect several households, and the damage often shows up first as stains, peeling paint, or damp patches near the parapet walls. Bitumen membrane, priced at SAR 15–35 per m², is a common choice for this job because it forms a continuous sheet over the roof and can be laid over a properly prepared surface.
The location matters. The centre of Khamis Mushait sits about 1998 m above sea level (SRTM open elevation data), which means the area is higher and cooler than many parts of the Kingdom, yet still receives strong sun and sudden rain. That combination places repeated stress on the membrane, so the approach should focus on good surface preparation, correct laps at the joints, and careful sealing around drains, pipes and upstands. Where a roof is also insulated, XPS boards at SAR 10–30 per m² may be discussed as part of the overall system, but the membrane itself should always be checked for how it will handle daily heating and cooling.
Before the visit, ask the provider to look at the roof itself rather than only the ceiling below, and to explain how they will treat cracks and old patches. Ask whether the price quoted is per m² for the bitumen membrane alone, or whether crack injection at SAR 40–115 per metre or liquid roof waterproofing at SAR 10–25 per m² is also included. Ask who will be responsible for the roof if the building is shared, and whether the work will be scheduled around residents' access to the terrace. A clear written scope gives you a fair basis for comparing offers.
In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
