Before we start: what we know about Hafr Albatin

Team note on Hafr Albatin: 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 Hafr Albatin sits about 312 m above sea level (SRTM open elevation data).

Roof waterproofing work for restaurants in Hafr Albatin starts with the basics of the site, because the roof of a commercial kitchen carries more than rain. The centre of Hafr Albatin sits about 312 m above sea level (SRTM open elevation data), so the first things we check are the roof's existing layers, the slope toward drainage outlets, and any ponding that shows where water has been sitting. A restaurant roof often takes hot air from extraction units, condensate from air conditioners and grease-laden vapour, so the technician looks first at the condition of the surface where those pipes and units rest. Liquid roof waterproofing is priced at SAR 8–25 per m², while bitumen membrane is SAR 15–35 per m², and the choice between them depends on what we find underneath, not on the price alone.

Several things are left for the site visit, because they cannot be judged from a description. The technician needs to measure the roof area in person, walk the parapets and upstands, and check the junctions where the roof meets walls, lift lines and rooftop equipment. Cracks are assessed on the spot; crack injection is charged per metre at SAR 40–120 per m, so the length and depth of each crack must be recorded before any quote is settled. The condition of any tank on the roof is also inspected at this stage, since tank internal coating ranges from SAR 25–60 per m² and needs a clear view of the existing lining. Where insulation is needed under a new finish, XPS boards at SAR 12–30 per m² are considered only after the substrate has been read and the moisture level noted.

To help the technician arrive prepared, the owner or manager should share the layout of the kitchen below the roof, the position of extraction fans and drains, and any record of past leaks, including the rooms they affected and the season they appeared. Photographs taken after rain are especially useful, as they show where water actually travels. Access arrangements matter too: note the times the restaurant is quietest, whether the roof can be reached without passing through food preparation areas, and any safety rules the building follows. With this information, the visit can focus on the real problem areas and the final scope of work will reflect the roof as it actually is.

For restaurants, visits are planned outside service hours and recorded for the premises file.

Signs that call for roof waterproofing

These are the signs most often linked to roof waterproofing:

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

Causes we see in the field

• Cracks in the roof slab — we check this before anything else.
• A common cause: wrong falls towards the drains.
• A common cause: damaged waterproofing around tank and AC bases.

Tools and methods, and when we use them

From the first visit to the report

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.
