Roof waterproofing in Afif: the local context

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.. Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

The centre of Afif sits about 1040 m above sea level (SRTM open elevation data).

Afif is a town in the Najd highlands of central Saudi Arabia, and the centre of Afif sits about 1040 m above sea level (SRTM open elevation data). That height matters for roofs here. Higher ground means cooler nights in winter, strong daytime sun for most of the year, and wide temperature swings between day and night. Those swings make surface coatings expand and contract, so the membrane you choose should be flexible enough to move with the roof rather than crack when temperatures change.

Each fact in the list below ties back to a practical choice on the roof. Liquid roof waterproofing is priced at SAR 8–25 per m², and it suits flat roofs with many corners and upstands because it can be applied seamlessly over irregular surfaces. Bitumen membrane at SAR 15–35 per m² gives a heavier, sheet-based layer that handles movement well. XPS boards at SAR 12–30 per m² add thermal insulation as well as a water barrier, which helps keep rooms below the roof more comfortable in hot months. Spray foam at SAR 20–45 per m² is another option for insulation and waterproofing in one step. Where cracks are already visible, crack injection at SAR 40–120 per metre seals them before any surface layer goes on, and this should be done first, not last.

Before summer heat and the rain season arrive, owners often make the same avoidable mistakes. The most common is coating a roof without cleaning it, so the new layer lifts off loose dust and old residue within a season. Another is ignoring drainage outlets and letting ponding water sit on the surface, which speeds up wear wherever the membrane is weakest. Owners also tend to skip the upstands around parapets and pipes, where water most often finds its way in. Finally, many people wait for the first leak before acting; checking the roof in early spring, while the weather is still mild, gives the coating time to cure properly before the heavy rain of the season begins.

Checks before summer and before the rain season catch problems while they are still small.

Signs that call for 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
• Water pooling on the roof
• Stains on the top-floor ceiling after rain

The most common causes

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

How we choose the tool 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.
