What is specific about Madinah for bitumen membrane
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).
Roof leaks are the most common problem with bitumen membrane work on apartment buildings. In apartment blocks, the roof is often shared by several households, so a small crack or a lifted lap can allow water to reach the top-floor ceilings long before anyone notices. The usual symptoms are damp patches, peeling paint near the edges of the ceiling, and water stains that appear after rain. A bitumen membrane is a common answer because it forms a continuous sheet over the roof, sealing the surface against standing water and the daily heat cycle that makes older roofs crack.
Madinah's location changes how the work should be planned. The centre of the city sits about 589 m above sea level, which places it on a high plateau rather than near the coast, so the local demand for roof protection is driven by heat, dust and occasional heavy rain rather than by sea spray. For apartment roofs in this setting, the membrane is commonly chosen with a bitumen membrane priced at SAR 15–35 per m², which can be compared against liquid roof waterproofing at SAR 10–25 per m² when the roof has few seams and a simpler shape. The choice depends on how many penetrations, parapets and drainage points the roof has, and a good installer will walk the roof before recommending one option over the other.
Before the visit, ask the provider to confirm the roof area in square metres and whether the price quoted is per m² so you can estimate the total. Ask how they will handle existing cracks or blistering, and whether the surface must be cleaned and primed first. Find out if the work will need access through a neighbour's flat or the building stairwell, and who will coordinate that with other owners. Ask whether the building's management or other residents need to be informed about water shut-offs or noise, and request a written scope that lists the materials and the warranty terms in plain language before you agree to start.
In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.

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 apartments?
We start with preparation (cleaning, priming and repairs), then torch welding (overlaps are welded and checked).
