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..
The centre of Madinah sits about 589 m above sea level (SRTM open elevation data), so the first thing a technician checks on a villa roof is how water will move off it and where it will collect. Bitumen membrane is a sheet system, and its success depends on laps, upstands and drainage outlets being right before any material goes down. Check the existing roof slope, the condition of the parapets and the position of rainwater outlets, because a membrane that ponds water will age faster than one that sheds it. Confirm the substrate is dry, clean and free of loose screed before work starts. Bitumen membrane is priced at SAR 15–35 per m², and that range reflects how much preparation the roof needs, so the visit should record the area and the amount of repair work separately.
What is left to the site visit is the part that cannot be judged from a drawing. The technician needs to see the real condition of the roof surface, look for blistering, cracks or old patches, and decide whether the existing layer can stay or must be stripped. The visit should also confirm access for hot-applied work, the position of pipes and fittings that pass through the roof, and whether any adjoining wall, terrace or balcony drains onto the area being treated. If the roof has a crack that needs sealing, crack injection is priced at SAR 40–120 per metre, so measuring the length of any defect on site helps the quote stay accurate. Where the roof meets a water tank or a bathroom above living space, note this too, since related work such as tank internal coating at SAR 25–60 per m² or liquid roof waterproofing at SAR 10–25 per m² may be considered alongside the membrane.
For the technician, the most useful information is a clear sketch of the roof with dimensions, slope direction, outlet positions and any upstands, plus photographs of each edge and each penetration. Record the access route, the hours when the household is available, and whether the roof is used for storage, a water tank or a rooftop unit that must be moved. Note any previous waterproofing and when it was applied, since this affects whether the old surface needs priming or full removal. Keeping these details together at the start means the technician arrives with a plan, works through the roof in order and leaves the homeowner with a membrane that has been fitted to the actual building rather than a generic one.
Villas often have several lines and tanks; we test them one at a time so the cause is clear.

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.
