Bitumen membrane in Baish: without breaking
In short: In Baish (Baish), bitumen membrane (without breaking) begins with the roof, falls and drains survey and the flood test; nothing is opened until the position is clear. The centre of Baish sits about 84 m above sea level (SRTM open elevation data). Published price: Bitumen membrane (per m²), SAR 15–35 per m²; anything else is quoted after the inspection.
Why bitumen membrane differs in Baish
Team note on Baish: 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 Baish sits about 84 m above sea level (SRTM open elevation data).
Bitumen membrane work in Baish most often fails at the edges, not in the middle of the roof. Where the membrane meets upstands, parapets, drains and roof penetrations, the seams can lift or split as the surface heats and cools. Those weak points are where water finds its way in, so a good job starts with a close look at these details rather than just the open area. For a roof, the usual cost range for bitumen membrane is SAR 15–35 per m², and the price should reflect how much detailing the roof actually needs.
Baish sits at about 84 m above sea level, and that matters for the approach. Local roofs take strong daytime sun and the temperature swings that come with it, so the membrane needs to be laid to allow for movement and be properly sealed at every junction. Drainage also needs attention, because the aim is to move water off the roof quickly and keep it from pooling at low points. If a roof is being compared with a lighter option, the liquid roof waterproofing range of SAR 8–25 per m² and the XPS boards range of SAR 12–30 per m² are worth reviewing against the building's needs, since each suits different conditions.
Before the visit, ask the installer to walk the roof with you and point out every upstand, drain and penetration they plan to treat. Ask how they will prepare the surface and what they will do about existing cracks or blisters. Confirm the per-m² basis of the quote and whether edge detailing is included or charged separately. Ask how the work will be protected from traffic and weather during the job, and whether they will explain the drainage plan before work starts. Clear answers to these questions tell you whether the job will be done properly in Baish, and they make it much easier to compare quotes on an equal footing.
The aim is to locate the cause with instruments first, so any opening is limited to one point.

How we choose the tool in Baish
| Method | What it helps with | Its role in Baish |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
From the first visit to the report
- Preparation: Cleaning, priming and repairs.
- Torch welding: Overlaps are welded and checked.
