Bitumen membrane in Madinah: the local context
The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Team note on Madinah: 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..
Bitumen membrane is the most common waterproofing choice for flat roofs in Madinah, and the usual problem is that a roof which looked sound after installation begins to leak once the membrane ages and cracks around parapets, drains and roof penetrations. Many homeowners only notice the damage when stains appear on the ceiling below, by which time water has already soaked into the roof slab and insulation. Regular inspection of the seams and edges is the simplest way to catch small splits before they spread.
Madinah sits at roughly 589 m above sea level, which means the city experiences strong daytime sun, wide temperature swings between day and night, and dry dust that settles on the roof surface. These conditions cause bitumen to expand and contract and gradually dry out, so the approach here should focus on surface protection and detailing at the edges rather than only on the membrane itself. A good installer will check how the membrane is lapped at the corners and whether the finish is suited to heat exposure. The published bitumen membrane range is SAR 15–35 per m², and the wider rate card for related work includes liquid roof waterproofing at SAR 10–25 per m² and XPS boards at SAR 10–30 per m², so it is worth asking whether a combination of these methods suits the roof's condition.
Before the visit, ask the provider to confirm the roof area in square metres so the quote can be compared against the published range, and ask what is included for edge flashing, drainage outlets and removal of any old membrane. Request a written description of the materials and the warranty terms, and ask who will inspect the roof after the work is finished. Clear answers to these questions make it much easier to judge whether a quoted price is fair for the work described.

When do you need bitumen membrane?

- No protection layer.
- Seams that were not welded properly — we check this before anything else.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| 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 |
The steps in order
- Preparation: Cleaning, priming and repairs.
- Torch welding: Overlaps are welded and checked.
- Details: Upstands, drains and bases.
- Protection and flood test: Protection is laid after a successful flood test.

Common questions about bitumen membrane in Madinah
What is the difference between standard spraying and integrated pest management?
Standard spraying treats visible symptoms only, while integrated pest management includes diagnosis, sealing entry points, and multiple methods for longer-lasting results.
Could the leak be caused by weak waterproofing rather than the pipes?
Yes, damage to the waterproofing layer beneath the bathroom floor is one of the most common causes of leaks, especially in older buildings. In this case, water seeps through the tile joints into the screed and then down to the ceiling below. A specialized inspection can distinguish this from a pipe leak.
What is the difference between drain unblocking and drain cleaning?
Unblocking removes an existing blockage that prevents drainage, while cleaning is a preventive procedure that removes deposits and grease from pipes before they cause a blockage.
Where does bitumen membrane (cost & published offers) start in Madinah?
