Roof waterproofing in Almajardah: the local context

Team note on Almajardah: 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 Almajardah sits about 2035 m above sea level (SRTM open elevation data).

Roof leaks are the most common complaint in apartment buildings, and they usually start at the joints, parapets and drainage outlets rather than in the middle of the slab. Water finds these weak points, seeps into the top floor ceiling and can stain paint, blister plaster and damage electrics before residents notice the problem clearly. For a shared roof that serves several flats, the question is rarely whether to waterproof but which system suits the surface and how far the work should extend.

In Almajardah, the centre sits about 2035 m above sea level (SRTM open elevation data), so the approach should account for a higher, more exposed site where temperature swings and wind can stress roof coverings over time. Crews working at this elevation should expect that surfaces may need thorough cleaning and drying before any product goes on, and that open-air curing can be affected by changing conditions. Liquid roof waterproofing is typically priced at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 12–30 per m², so the chosen system should match the roof's condition and how much exposure it receives. Cracks are often treated separately, with crack injection priced at SAR 40–120 per metre, so ask whether it is included in the quote.

Before the visit, ask the provider to confirm the roof area in square metres and whether the quote covers parapets, outlets and any cracks you have noticed. Ask which system they recommend for your roof and why, and whether the price is per square metre or a fixed sum. Check who will carry out the surface preparation, how the work will be protected from residents' access, and whether any water tanks or basements in the same building will also need attention. Finally, ask what warranty or follow-up inspection they offer, in writing, before agreeing to any work.

Signs that call for roof waterproofing

These are the signs most often linked to roof waterproofing:

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

Causes we see in the field

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

Tools and methods, and when we use them

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.
