Roof waterproofing in Madinah: before buying or handover
In short: Roof waterproofing (before buying or handover) in Madinah starts with the roof, falls and drains survey, then the moisture meter for ceilings and walls, before anything is opened. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Pricing starts from Liquid roof waterproofing (per m²) (SAR 10–25 per m²), and other items are quoted after the visit.
Roof waterproofing in Madinah: the local context
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 waterproofing in Madinah starts with the altitude. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data), which means roofs here face a dry, high-sun climate rather than the humid coastal conditions found in Jeddah. Before buying or handing over a property, the first thing to check is the roof surface itself: look for hairline cracks, lifted edges around parapets and drainage outlets, and any ponding after the last rain. Because daytime heat on roof slabs is intense, shrinking and splitting of old coatings is common, so the condition of the existing membrane matters more than its age alone. Note too whether the roof has been painted or coated recently, since a fresh layer can hide underlying cracks.
Several details are left to the site visit, because they cannot be judged from a photograph or a document. A technician needs to measure the roof area, confirm the slope towards outlets, and test whether the existing layer is bonded or peeling. They also need to decide between liquid roof waterproofing, bitumen membrane, spray foam, or XPS boards, since each suits different roof structures and levels of exposure. For rough budgeting only, liquid roof waterproofing is listed at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 25–35 per m², and XPS boards at SAR 10–30 per m². Where a roof joins a basement, bathroom or water tank, the work changes, so the wider property should be inspected at the same time. Basement waterproofing is listed at SAR 50–150 per m², crack injection at SAR 40–120 per m, and tank internal coating at SAR 25–60 per m².
To help the technician, gather what you already know before the visit. Record the roof's approximate area, the year of any previous waterproofing work, and the location of recent leaks, including whether they appear after rain or during hot afternoons. Photographs taken after a rainfall are especially useful, as they show where water actually collects. Mention any tank on the roof, any shared walls with neighbouring buildings, and whether the roof is accessible for foot traffic or equipment. Clear answers to these points let the visit focus on the roof itself rather than on basic questions, and they make any written quotation easier to compare.
Before buying or taking over a property, an inspection gives you findings in writing before you sign.
When do you need roof waterproofing?
These are the signs most often linked to roof waterproofing:
- Water pooling on the roof
- Stains on the top-floor ceiling after rain
- The old waterproofing is cracking
Where the problem usually comes from
- Wrong falls towards the drains — we check this before anything else.
- Damaged waterproofing around tank and AC bases — we check this before anything else.
- Cracks in the roof slab — we check this before anything else.
Tools and methods, and when we use them
| 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 |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| 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
- Survey: Falls, drains and the condition of the old layer are recorded.
- Preparation: Cleaning and repairs before any new layer.
- Primer: The base coat that the system needs.
- Waterproofing layers and details: Corners, upstands and bases get their own detail.
- Flood test: The roof is flooded and checked before it is covered.

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.
