Why roof waterproofing differs in Afif

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.

Roof leaks are the most common problem we see on clinic roofs in Afif. Clinics often have flat roofs carrying air-conditioning units, plant, and medical waste or storage areas, and the repeated foot traffic and equipment work wear down the surface. Small cracks and failed joints let water track into ceilings above consulting rooms and treatment areas, where staining and damp can quickly become a hygiene concern as well as a repair cost.

Afif sits at about 1040 m above sea level, which means the local climate and the way a roof is used are different from the coastal cities. The centre of Afif sits about 1040 m above sea level, so the approach for a clinic roof here starts with a close look at the surface and at how it is drained, rather than assuming the same system used elsewhere will suit. Options such as liquid roof waterproofing, typically priced at SAR 8–25 per m², and bitumen membrane, typically priced at SAR 15–35 per m², can both be considered, with the choice depending on the condition of the existing layer, how much access the roof gets, and whether any insulation boards are needed beneath the finish, where XPS boards are typically priced at SAR 12–30 per m². Where cracks run through the slab, crack injection at SAR 40–120 per metre may be needed before any surface system is applied.

Before the visit, ask the provider to confirm which system they propose and why it suits your roof, and to explain how they will protect equipment and keep the clinic running during works. Ask how they will check for hidden moisture, what they will do about existing drains and outlets, and how the work will be inspected at the end. A clear written scope, with the area measured in square metres, will make it easier to compare quotes on a like-for-like basis.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

Signs worth paying attention to

These are the signs most often linked to roof waterproofing:

• 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.
• A common cause: damaged waterproofing around tank and AC bases.
• A common cause: wrong falls towards the drains.

Tools we use in Afif

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.
