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 leaks are the most common problem for hotels and serviced apartments in Aldiriyah, and they tend to show up first as stains on top-floor ceilings and damp patches around parapets and rooftop plant bases. For a property with guests coming and going, even a small leak can mean refunds, complaints and rooms taken out of service, so owners often want a fix that is fast as well as durable. Because the roof is the main barrier between the building and the weather, a problem that looks minor from inside can have spread under the surface before anyone notices.

The centre of Aldiriyah sits about 655 m above sea level, which shapes how we approach the roof. Our advice for this area is to plan around the building's exposure rather than apply a single standard system everywhere. Liquid roof waterproofing is priced at SAR 8–25 per m², and bitumen membrane at SAR 15–35 per m², so the choice between them depends on the roof's condition, access and how much downtime the property can accept. Where the roof is used for guest areas or plant, we also look at cracks and joints closely, since crack injection is priced at SAR 40–120 per metre and is often the most precise repair for a single failing line. Tank internal coating at SAR 25–60 per m² and XPS boards at SAR 12–30 per m² may also be relevant if the rooftop water storage or insulation is part of the same job.

Before the visit, ask the provider to confirm which roof areas they plan to inspect and whether they will check the parapets, drains and plant bases as well as the main surface. Ask how they will protect occupied rooms and guest access during the work, and whether the quote separates each item by square metre or by metre so you can compare it with the ranges above. It also helps to ask for photographs of any previous leak repairs on similar hotel or apartment roofs, and to check whether the quote includes the cost of crack injection if cracks are found. Clear answers to these questions will make the site visit more useful for both sides.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

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

Causes we see in the field

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