Roof waterproofing in Sharurah: the local context

Team note on Sharurah: 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 Sharurah sits about 724 m above sea level (SRTM open elevation data).

Main roads in or near Sharurah: King Abdulaziz Road, King Fahd Road.

Roof waterproofing in Sharurah most often starts with cracks and failed sealant at parapets, roof edges and where pipes or drains pass through the slab. Water finds these weak points during rain, and the damage shows up first as staining on the ceiling below. Left alone, it works into the concrete and reinforcement, so a small leak can become a much larger repair. Good work begins with finding exactly where water enters, not just covering the surface.

The local setting shapes the approach. The centre of Sharurah sits about 724 m above sea level (SRTM open elevation data), which places the town on high ground in the south of Saudi Arabia. Roofs here face strong sun during the day and sharp temperature changes between day and night, and both cause the surface to expand and contract. That movement is hard on coatings and joints, so a waterproofing system needs to tolerate movement rather than sit rigidly on the slab. Where cracks are present, crack injection is usually priced per metre, typically SAR 40–120 per m, and it is often used before the main coating goes on. For open roof areas, liquid roof waterproofing is commonly priced at SAR 8–25 per m², while bitumen membrane runs SAR 15–35 per m² and XPS boards SAR 12–30 per m² where insulation is also wanted.

Before the visit, ask the provider a few clear questions. Ask whether they will inspect the roof and the ceiling below it, and whether they will mark the suspected leak points before quoting. Ask which system they propose and why it suits your roof, and what preparation the surface needs. Request a written, itemised quote that shows the area measured, the unit rate and the work included. Finally, ask for a verifiable technical report that records the findings, the materials used and the areas treated, so you have a clear record of the work for future reference.

Each job ends with a written report that carries a verification code you can check on our site.

When do you need roof waterproofing?

The following signs are worth checking before they grow:

• The old waterproofing is cracking
• Stains on the top-floor ceiling after rain
• Water pooling on the roof

The most common causes

• Cracks in the roof slab — we check this before anything else.
• Damaged waterproofing around tank and AC bases.
• Wrong falls towards the drains — we check this before anything else.

Tools and methods, and when we use them

The steps in order

1. Survey: Falls, drains and the condition of the old layer are recorded.
2. Preparation: Cleaning and repairs before any new layer.
3. Primer: The base coat that the system needs.
4. Waterproofing layers and details: Corners, upstands and bases get their own detail.
5. Flood test: The roof is flooded and checked before it is covered.
