Bitumen membrane in Aljumum: the local context
Team note on Aljumum: 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.. The centre of Aljumum sits about 200 m above sea level (SRTM open elevation data).
Roof leaks are the most common problem for hotels and serviced apartments that use bitumen membrane. Guests notice stains on ceilings and damp patches near parapets long before management knows where the water is getting in. In a building with occupied rooms, the cost is not only the repair but the lost nights and complaints while work is underway. Bitumen membrane on a flat roof is usually priced at SAR 15–35 per m², and the real question is whether the existing layer is still bonded, whether laps and upstands are sound, and whether drainage outlets are clear.
Aljumum sits about 200 m above sea level, so the approach has to account for the local setting. Elevation alone does not decide how a roof should be treated, but it is one of the facts a contractor should note when planning the scope and the sequence of works. A roof that is exposed and well above the surrounding ground should be checked for wind-lifted edges, loose flashings and gravel displacement before any new membrane is laid. For a hotel with guests on the top floor, the sequence matters as much as the materials, so the work can be planned around quieter periods and access routes that do not disturb the rooms below.
Before the visit, ask the provider to confirm which areas are covered by the quote, since roof membrane, parapet detailing and any insulation boards are priced separately. If XPS boards are proposed under the membrane, ask for the per m² rate of SAR 12–30 to be shown as its own line. Ask how old the current roof is, whether previous repairs are documented, and where the water was last seen entering. Ask whether the surveyor will walk the roof with the building manager and photograph the outlets. A clear answer on these points tells you whether the quote reflects your actual building.
For hotels and serviced apartments, rooms are handled in batches to keep units available.
