Bitumen membrane in Yanbu: emergency
In short: In Yanbu (Yanbu), bitumen membrane (emergency) begins with the roof, falls and drains survey and the flood test; nothing is opened until the position is clear. The centre of Yanbu sits about 6 m above sea level (SRTM open elevation data). Pricing starts from Bitumen membrane (per m²) (SAR 15–35 per m²), and other items are quoted after the visit.
Why bitumen membrane differs in Yanbu
Team note on Yanbu: 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.. Main roads in or near Yanbu: King Abdulaziz Road, Umluj Road, Al Hanan Street.
The centre of Yanbu sits about 6 m above sea level (SRTM open elevation data). Yanbu is about 1.2 km from the sea coast (OpenStreetMap).
An owner of a flat or villa roof in Yanbu usually notices the problem after a rain shower: a damp patch on the ceiling below, bubbling paint, or water tracking along a parapet. Because the roof is often the only layer keeping the building dry, a leak that is left alone can spread into insulation and the rooms beneath quickly. Many owners want the repair done at once, before the next storm, and they want a clear idea of what it will involve.
The city centre of Yanbu sits about 6 m above sea level, and the town lies roughly 1.2 km from the coast. For a roof owner, this means the property is low-lying and close to the sea, so rainwater that cannot drain away may pool on flat surfaces and seek the weakest point. The bitumen membrane typically used for roofs in this setting is priced at SAR 15–35 per m², and that figure is a useful starting point when you ask a contractor for a quote. Any repair should be checked against the full area of the roof, not only the visible wet patch, because water often travels across the surface before it appears indoors.
Practical steps in order: first, keep the area below dry by moving furniture and placing containers under the drip, and photograph the damage for your records. Second, avoid walking on the membrane during or just after rain, since foot traffic can split a weakened surface. Third, ask a contractor to inspect the roof, mark the damp zones, and confirm whether the leak comes from the membrane, a crack, or a drainage outlet. Fourth, request a written quote that states the area in square metres and the rate applied for the bitumen membrane. Fifth, once the work is done, have the drains and outlets cleared so that water leaves the roof rather than sitting on it.
If water is flowing, close the main valve first, then call or message with photos.

Tools and methods, and when we use them
| Tool | What it finds | When we use it in Yanbu |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
From the first visit to the report
- Preparation: Cleaning, priming and repairs.
- Torch welding: Overlaps are welded and checked.
