What is specific about Aldiriyah for roof waterproofing

The centre of Aldiriyah sits about 655 m above sea level (SRTM open elevation data). 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..

Roof waterproofing in Aldiriyah begins with the height of the ground itself. The centre of Aldiriyah sits about 655 m above sea level (SRTM open elevation data), so a roof here faces a dry, open setting rather than coastal humidity, and that shapes what a technician checks first. The first questions are about the existing surface: whether the slope drains properly, whether there is ponding after rain, and where the old layer has lifted or split. Liquid roof waterproofing is priced at SAR 8–25 per m², and bitumen membrane at SAR 15–35 per m², so the surface condition and the drainage path usually decide which system is sensible before any cost is discussed.

Several things are left to the site visit, because they cannot be judged from a description. The technician needs to see the roof itself: the extent of any cracks, the state of the parapets and upstands, the condition of drain outlets, and whether the substrate is sound enough to take a new layer. Crack repair is measured per metre, at SAR 40–120 per m, so the length and depth of cracks changes the figure considerably. Insulation may also be part of the job, and XPS boards at SAR 12–30 per m² or spray foam at SAR 20–45 per m² are options only after the existing build-up is understood. None of these choices should be fixed from the street or from a photograph alone.

To help the technician, prepare basic information before the visit. Note the roof area in square metres, any recent leaks and the rooms beneath them, and whether the roof is accessible for foot traffic or used for water tanks. If there is a tank on the roof, mention it, since tank internal coating is priced separately at SAR 25–60 per m². Also record any previous waterproofing work and its approximate age, and whether any cracks have been patched before. A clear account of these points lets the visit focus on the surface, the drainage and the cracks, and makes the eventual recommendation easier to follow.

Each job ends with a written report that carries a verification code you can check on our site.

These are the signs most often linked to roof waterproofing:

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

Causes we see in the field

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

Tools we use in Aldiriyah

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.
