Roof waterproofing in Madinah: with a verifiable technical report
In short: In Madinah (Madinah), roof waterproofing (with a verifiable technical report) begins with the roof, falls and drains survey and the moisture meter for ceilings and walls; nothing is opened until the position is clear. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Published price: Liquid roof waterproofing (per m²), SAR 10–25 per m²; anything else is quoted after the inspection.
What is specific about Madinah for roof waterproofing
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).
The centre of Madinah sits about 589 m above sea level, according to SRTM open elevation data. For roof waterproofing, this altitude matters because it places the city in a dry, inland setting where roofs are exposed to strong sun and high daytime heat rather than constant sea air. That heat cycles the roof surface between very hot and cooler temperatures, which can stress coatings and joints over time. Good preparation and a membrane that handles movement are therefore more important than simply applying a thin layer.
Each fact links to a practical effect on the work. Because the centre is elevated and exposed to strong sun, we recommend choosing a roof system with reflective or protective topcoats, and checking that the surface is clean and dry before application. Liquid roof waterproofing typically falls within SAR 10–25 per m², bitumen membrane within SAR 15–35 per m², and XPS boards within SAR 10–30 per m². These ranges help owners compare options on a like-for-like basis, but the final choice should depend on the roof's condition, access, and how much thermal movement it experiences. Where cracks are present, crack injection is priced at SAR 40–120 per metre, and sealing these before the main coat prevents water from tracking beneath the new layer.
Owners often avoid several common mistakes when they plan roof work carefully. They do not paint over damp or dusty surfaces, because adhesion fails quickly. They do not skip repairing cracks and drainage outlets, since small gaps become the main route for leaks. They also do not judge a quote by price alone; a lower rate per m² means little if the scope excludes preparation, primer, or repairs. Asking for a clear breakdown of each item, and for a written technical report describing materials and test steps, helps ensure the roof is protected for the long term.
Each job ends with a written report that carries a verification code you can check on our site.
Signs worth paying attention to
The following signs are worth checking before they grow:
- The old waterproofing is cracking
- Water pooling on the roof
- Stains on the top-floor ceiling after rain
The most common causes
- Cracks in the roof slab.
- Wrong falls towards the drains — we check this before anything else.
- A common cause: damaged waterproofing around tank and AC bases.
Tools we use in Madinah
| Tool | What it finds | When we use it in Madinah |
|---|---|---|
| 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 |
| 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
- 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.

Common questions about roof waterproofing in 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 roof waterproofing (with a verifiable technical report)?
We start with survey (falls, drains and the condition of the old layer are recorded), then preparation (cleaning and repairs before any new layer).
How much does roof waterproofing cost in Madinah?
