Bitumen membrane for residential buildings in Madinah
In short: In Madinah (Madinah), bitumen membrane for residential buildings begins with the roof, falls and drains survey and the flood test; nothing is opened until the position is clear. The centre of Madinah sits about 589 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.
Before we start: what we know about Madinah
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.. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data).
The first thing a technician checks for bitumen membrane work in Madinah is the surface the membrane will be bonded to, because the membrane is only as good as its base. The city's centre sits about 589 m above sea level, which places it on a plateau where daytime heat and the sharp temperature swings between day and night put real stress on roof and wall surfaces. Before any membrane is laid, the surface should be sound, dry where possible, and free of loose material, so the technician looks first for cracks, old bitumen that has lifted, and any standing water. Bitumen membrane for residential roofs and walls typically falls in the range of SAR 15–35 per m², and the price reflects how much preparation the surface needs, which is why the first inspection matters so much to the final cost.
Several points are left to the site visit, because they depend on the particular building and cannot be judged from a description. The technician will look at the roof slope and drainage to see whether water collects in low spots, the condition of any parapets and upstands where the membrane must turn up, and how the membrane will meet pipes, drains and roof-mounted fixtures. The site visit also decides whether a cracked area needs crack injection, priced at SAR 40–120 per metre, before the membrane goes down, and whether a different system such as liquid roof waterproofing, at SAR 10–25 per m², would suit a particular section better. Access, the age of the existing layers and any signs of moisture coming through from below are all judged on the spot rather than assumed.
Information that helps the technician prepare is simple and worth gathering before the visit. It is useful to know which parts of the building have leaked before, when the last waterproofing was done, and whether any previous coating is still in place. Knowing the roof's approximate area in square metres allows a fair estimate at the SAR 15–35 per m² rate, and noting which areas are used as terraces or storage helps the technician plan protection for the finished surface. Clear access to the roof and a record of any existing damage will make the visit shorter and the recommendation more accurate.
For a residential building, shared risers, tanks and pumps are checked as one system.

Tools and methods, and when we use them
| Tool | What it finds | When we use it in Madinah |
|---|---|---|
| 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 |
How the work is done, step by step
- 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.

Short answers for 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.
What is the first step of bitumen membrane for residential buildings?
We start with preparation (cleaning, priming and repairs), then torch welding (overlaps are welded and checked).
