Roof waterproofing in Afif: the local context

The centre of Afif sits about 1040 m above sea level (SRTM open elevation data). Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

Team note on Afif: 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..

Roof waterproofing for restaurants in Afif starts with the elevation. The centre of Afif sits about 1040 m above sea level, so the roof is exposed to a cooler climate and a different range of conditions than coastal sites. Before any product is discussed, the technician looks at the roof surface, the drainage outlets, and the points where the roof meets kitchen extract ducts, air conditioning units and parapet walls. These junctions are where water most often gets in, and where grease-laden vents and heavy equipment can wear through a membrane over time.

Several decisions depend on what is found on the roof, so they are left to the site visit. The choice between liquid roof waterproofing, at SAR 8–25 per m², and a bitumen membrane, at SAR 15–35 per m², depends on the existing surface, how much foot traffic the roof carries, and whether the restaurant needs a fast turnaround. Spray foam, at SAR 20–45 per m², and XPS boards, at SAR 12–30 per m², are assessed for insulation value and for whether the old layer can stay in place. Crack injection, at SAR 40–120 per metre, is only scoped once the cracks have been mapped and their movement understood. Every figure quoted is a range, and the final cost follows the measured area and the condition the visit reveals.

Information that helps the technician makes the visit faster and the quote more accurate. Please note the roof area and any sections that are already leaking, the age and type of the current covering, and the location of kitchen exhaust fans, plant platforms and rooftop tanks. If a rooftop water tank is involved, mention it, since tank internal coating is priced separately at SAR 25–60 per m². Photos of ceiling stains taken after rain, and the dates when leaks were first noticed, are very useful. Access arrangements matter too: tell us when the kitchen is quietest so that work over the dining area can be planned without disturbing service.

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

Signs worth paying attention to

If you notice one of these signs in Afif, it is a good moment to talk to the team:

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

Where the problem usually comes from

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

Tools and methods, and when we use them

How the work is done, step by step

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.
