What is specific about Afif for roof waterproofing

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.. 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.

Ponding water is the most common roof problem for warehouses, and it is usually the reason a waterproofing job is needed at all. Flat or low-slope warehouse roofs collect rainwater in shallow hollows, and over time that standing water finds its way into laps, fixings and cracked surfaces. Liquid roof waterproofing, priced at SAR 8–25 per m², is often the first option considered because it can be applied as a seamless layer over an existing roof. Bitumen membrane, at SAR 15–35 per m², is another route where a heavier, sheet-based barrier is needed.

Afif sits at about 1040 m above sea level, and that elevation shapes how we approach a warehouse roof here. At this height, the surface can experience large day-to-night temperature swings, which cause the roof covering to expand and contract. For that reason, the choice of coating or membrane should allow for movement rather than relying on a rigid finish that will split. Where a roof is being insulated as part of the work, XPS boards at SAR 12–30 per m² may be considered alongside the waterproofing layer, so the two systems are planned together rather than treated as separate jobs.

Before a site visit, it helps to have a few details ready. Tell us the roof area in square metres, the type of existing covering, and whether water is pooling in particular places or leaking into the building below. Note any cracks, bubbling or patched sections you have already seen, and mention whether the roof is accessible for foot traffic and equipment. Let us know if the warehouse stores goods that are sensitive to moisture, as this affects how urgently the work should be scheduled. With this information, the visit can focus on the areas that matter most and give you a clearer picture of the options for your building.

For warehouses, work is phased around operations and stored goods.

When do you need roof waterproofing?

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

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

Where the problem usually comes from

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

Tools we use in Afif

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.
