Bitumen membrane in Albaha: the local context

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).

Albaha sits about 2178 m above sea level, and that height shapes how villa roofs are exposed to the weather. Bitumen membrane is most often chosen for flat roofs and terraces, where ponding water and repeated heat cycles can open small gaps at laps, joints and around parapets. For villa owners, the most common problem is not a single dramatic leak but slow seepage that appears after a wet spell, staining ceilings in the top storey and bubbling the surface where the membrane has lost adhesion.

Because the centre of Albaha is high and open, the approach starts with the roof falls and drainage outlets. A bitumen membrane only performs well if water can run off quickly, so the existing slope, outlet size and any blocked drains are checked before any material is priced. Parapet walls, rooftop water tanks and pipe penetrations are the usual weak points, and they are sealed and detailed separately so the membrane does not simply stop at an edge. The membrane itself is typically priced at SAR 15–35 per m², but the real cost depends on how much preparation the existing surface needs. Where the roof has cracks, the fix may include crack injection at SAR 40–120 per metre before the membrane goes on, and a liquid roof finish at SAR 8–25 per m² is sometimes offered as an alternative for lighter wear.

Before the visit, it helps to have a few details ready. Tell us the roof area, whether the roof is accessible or used as a terrace, and where you have seen water enter. Let us know if there is a rooftop tank, since tank internal coating at SAR 25–60 per m² is a separate job. Mention any past repairs, because old coatings can affect how new membrane bonds. Ask for the inspection to note the drainage, the state of the edges and the likely scope, so you receive a written assessment of the work before any agreement is made.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.

Signs worth paying attention to

If you notice one of these signs in Albaha, it is a good moment to talk to the team:

• Old rolls that are cracking
• A flat concrete roof that needs waterproofing

Causes we see in the field

• A common cause: seams that were not welded properly.
• No protection layer.

Tools and methods, and when we use them

From the first visit to the report

1. Preparation: Cleaning, priming and repairs.
2. Torch welding: Overlaps are welded and checked.
3. Details: Upstands, drains and bases.
4. Protection and flood test: Protection is laid after a successful flood test.
