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).

Aldiriyah sits on higher ground, with the centre of the town about 655 m above sea level. For a roof, that elevation matters: the site is exposed to strong sun, wind and heavy temperature swings between day and night, all of which stress roof surfaces. Office buildings and commercial complexes here often carry large flat roofs that take the full brunt of the climate, so the waterproofing system has to tolerate constant heat and movement rather than just keeping out the occasional shower.

Because of this exposure, we match the roofing system to the roof itself. Liquid roof waterproofing, priced at SAR 8–25 per m², suits large open decks where a seamless skin is needed around plant bases and drains. Bitumen membrane, at SAR 15–35 per m², gives a thicker layer for roofs that see heavy foot traffic or need a durable sheet finish. Where the roof is insulated, XPS boards at SAR 12–30 per m² protect the insulation layer and help manage heat transfer. Each option is chosen after inspecting the existing deck, the slope, and how water currently moves across the roof, so that the system works with the building rather than against it.

Owners of offices and commercial complexes commonly make a few avoidable errors. The most frequent is waiting for a visible leak before acting, when small cracks and lifted seams have already let water into the structure. Another is treating the roof in isolation: water that gets past a roof can travel down into walls and basements, which is why the same care is needed for rooftop tanks and bathrooms in the building. Finally, many owners choose the lowest quote without comparing what is included, such as surface preparation, drainage correction and the coating thickness applied. A clear scope written before work begins protects the building and the budget over the long term.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.

Signs worth paying attention to

The following signs are worth checking before they grow:

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

Where the problem usually comes from

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

Tools we use in Aldiriyah

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.
