Bitumen membrane in Albaha: before buying or handover

What is specific about Albaha for bitumen membrane

Team note on Albaha: 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 Albaha sits about 2178 m above sea level (SRTM open elevation data).

The first thing a technician checks in Albaha is the altitude. The centre of Albaha sits about 2178 m above sea level, which means the air is cooler and the sun on a roof can still be strong, while night-time temperatures can drop noticeably. These swings matter for bitumen membrane, because a membrane that softens in heat and then stiffens in cold needs a clean, dry substrate and proper laps to stay sealed. Before any price is discussed, the surface underneath is inspected for cracks, old ponding marks, and loose screed, since no membrane will perform well over a weak base. The bitumen membrane itself is priced at SAR 15–35 per m², and that range only means something once the area and the condition of the substrate are known.

Other details are left to the site visit, because they cannot be judged from a description. The technician measures the roof or deck area, notes the number of upstands, drains and penetrations, and decides whether the membrane can run straight through or needs to be cut and detailed around each one. The visit also records any existing cracks, since crack injection is charged separately at SAR 40–120 per metre and can change the total cost considerably. If the roof is being covered in a different way, such as liquid roof waterproofing at SAR 8–25 per m² or XPS boards at SAR 12–30 per m², the technician compares those options on the spot. Where water is entering from below rather than above, the plan may shift toward basement waterproofing (SAR 50–150 per m²) instead, and that decision is made only after the site has been seen.

To help the technician prepare, it is useful to have the following ready. Share the approximate roof or deck area in square metres, a description of the current surface and any past leaks, the location and number of drains and parapets, and the access route for materials on the roof. Note whether the building has a water tank on the roof, because tank internal coating is priced at SAR 25–60 per m² and is often arranged at the same time. Photographs of ceilings or walls showing damp marks are also helpful. With this information, the technician can give a realistic scope before the work begins, and the handover can be checked against the same list.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.
