Roof waterproofing in Aldiriyah: the local context

Team note on Aldiriyah: 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 Aldiriyah sits about 655 m above sea level (SRTM open elevation data).

Roof leaks are the most common problem on rest houses and farms in Aldiriyah, and they usually show up as damp patches on ceilings after rain, cracks in the parapet walls, and water pooling on flat roof areas that were built without a proper slope. On larger farm buildings and rest houses, the roof area is often wide and exposed, so small failures spread quickly into the rooms below. Our first step is always a full inspection of the roof surface, the upstands and the drainage points before recommending any system.

Aldiriyah sits at about 655 m above sea level, which matters for how we approach the job. At this height the site receives different weather exposure than lower coastal areas, and the sun and temperature swings across the day put steady stress on roof surfaces. For that reason we look closely at how a membrane will handle expansion and contraction, and we do not assume a single product suits every roof. Liquid roof waterproofing, bitumen membrane and spray foam each behave differently under heat and movement, so the choice depends on the roof's age, its slope and how much movement it has already shown. Where the roof is in good condition, a liquid coating may be enough, while older roofs with wider cracks may need a bitumen membrane or a combined approach.

Before the visit, ask the provider to confirm the roof type, its approximate area in square metres, and whether there are visible cracks or previous repairs. It also helps to tell them whether the leak appears only during heavy rain or after every rain, and which rooms are affected. Ask how the price is calculated, since liquid roof waterproofing is commonly quoted at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 12–30 per m², and ask what the quote includes. Finally, ask whether crack injection is needed, which is quoted at SAR 40–120 per metre, so that the visit can be planned around the real condition of the roof.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs that call for roof waterproofing

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

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

The most common causes

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

Tools and methods, and when we use them

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.
