Bitumen membrane in Madinah: before summer & rain season
In short: In Madinah (Madinah), bitumen membrane (before summer & rain season) 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
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 on roofs is most often asked about because summer heat in Madinah softens and cracks the surface over time, and when the rainy season arrives, water finds the seams and laps that have opened up. Homeowners and building managers usually notice the problem as a stain on the ceiling below or a damp patch along a parapet, long after the water has started moving through the structure. Bitumen membrane typically costs SAR 15–35 per m², and that range reflects how much preparation the existing surface needs before a new layer can bond properly.
Madinah's location shapes how we approach this. The city centre sits about 589 m above sea level, so the climate is a dry, hot interior climate in which the sun works hard on exposed roofs through the day and the night air cools them quickly. That daily swing in temperature stresses the membrane, which is why the timing of work matters: we recommend getting the surface sealed well before the hottest months and before the first heavy rains, rather than waiting for a leak to appear. Because the sun is so intense, we also look closely at roof edges, upstands and drainage outlets, since these are where the membrane is most likely to lift. On roofs where the insulation below is also a concern, XPS boards (SAR 10–30 per m²) can be considered as part of the overall plan, and crack injection (SAR 40–120 per m) is used where a structural crack needs sealing before any surface layer goes on.
Before the visit, it helps to have a few details ready. Tell us the roof area, roughly how old the existing membrane is, and whether you have already seen water entering the building or only suspect it. Note any areas of ponding after rain, any visible cracks or blistering, and whether the roof is accessible for foot traffic or is used for water tanks or equipment. Ask the technician to explain how the surface will be prepared, what the quote covers, and how the work will be scheduled around the season. A clear list of these points lets the visit focus on the actual condition of your roof rather than general checks.
Checks before summer and before the rain season catch problems while they are still small.
When do you need bitumen membrane?
These are the signs most often linked to bitumen membrane:
- A flat concrete roof that needs waterproofing
- Old rolls that are cracking
The most common causes
- No protection layer.
- Seams that were not welded properly — we check this before anything else.
How we choose the tool in Madinah
| Method | What it helps with | Its role in Madinah |
|---|---|---|
| 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 |
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 (before summer & rain season)?
We start with preparation (cleaning, priming and repairs), then torch welding (overlaps are welded and checked).
How much does bitumen membrane cost in Madinah?
