Bitumen membrane for warehouses in Madinah
In short: Bitumen membrane for warehouses in Madinah starts with the roof, falls and drains survey, then the flood test, before anything is opened. 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.
Why bitumen membrane differs in 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).
Warehouse roofs in Madinah most often fail at the laps, upstands and drainage outlets rather than in the open field of the membrane, because the sheets are joined and cut around plant, fixings and gutters. Standing water that sits at low points or near outlets speeds up ageing of the bitumen, and small splits at seams can carry water into the building for a long time before anyone sees a stain on the ceiling. A bitumen membrane system is usually priced within the range of SAR 15–35 per m², but the real cost driver is how many details need sealing, not the flat area alone.
The local setting shapes how the membrane is specified. Madinah sits at roughly 589 m above sea level, so the site is inland and elevated rather than coastal, and the approach should focus on sun exposure, heat cycling and expansion across the roof rather than on salt-laden air. Bitumen softens in strong heat and stiffens in cooler nights, so the installer should consider the surface finish, the overlap widths and how the membrane is fixed to the deck so that movement does not pull the joins apart. Where a warehouse has a low-slope roof with several drainage points, the detailing around those points matters as much as the sheet itself. If the building also has a basement, waterproofing there is priced separately, at SAR 50–150 per m², and should be assessed on its own terms.
Before the visit, ask the provider to walk the roof with you and identify every upstand, penetration, outlet and seam, and to confirm which of these will be detailed individually. Ask how the existing surface will be prepared and whether any old membrane will be removed or overlaid, since that changes the scope and the price. Request a written breakdown that shows the membrane rate per m² alongside the cost of edge details, flashings and any repairs to cracks or blisters you have already noticed. It also helps to ask how the roof will be tested after installation, such as a check for ponding or a controlled water test at key points, and what the warranty covers and for how long.
For warehouses, work is phased around operations and stored goods.
Signs that call for bitumen membrane
These are the signs most often linked to bitumen membrane:
- Old rolls that are cracking
- A flat concrete roof that needs waterproofing
Where the problem usually comes from
- A common cause: seams that were not welded properly.
- A common cause: no protection layer.
How we choose the tool in Madinah
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| 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 |
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.

Questions from 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.
