Before we start: what we know about Khafji

Khafji is about 2 km from the sea coast (OpenStreetMap). The centre of Khafji sits about 9 m above sea level (SRTM open elevation data).

Main roads in or near Khafji: King Abdullah Road. Team note on Khafji: 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 most common problem with roof waterproofing for hotels and serviced apartments in Khafji is ponding water and slow leaks through roof slabs that have worn out their protection, often showing up as stains on the ceilings of top-floor rooms. Guests notice these quickly, and repeated patches can turn a short job into a recurring cost. The fix usually starts with finding where water is sitting and why, rather than simply covering the surface.

Khafji's location shapes how we approach the job. The town centre sits about 9 m above sea level and lies about 2 km from the coast, so rooftops here are exposed to salt-laden air and strong sun rather than sitting in a low, sheltered basin. For a roof, we typically compare options such as liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 12–30 per m², with the choice depending on the roof's condition, access, and how long the building can afford to have guest areas disrupted. Where a roof connects to a basement or a water tank, the scope may also include basement waterproofing at SAR 50–150 per m², bathroom waterproofing at SAR 15–40 per m², or tank internal coating at SAR 25–60 per m², so it is worth raising these early.

Before the visit, ask for the roof area in square metres and a note of any existing leaks, cracks, or previous repairs, along with the age of the current membrane if known. Ask whether the work will need to be scheduled around occupied rooms and whether crack injection, priced at SAR 40–120 per metre, is likely to be needed along joints or upstands. It also helps to confirm which parts of the building share a roof, a basement, or water storage, so the site visit can cover the full picture rather than only the visible surface.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

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.
• A common cause: damaged waterproofing around tank and AC bases.
• Cracks in the roof slab.

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.
