Roof waterproofing in Ahad Rafida starts with the altitude. The centre of Ahad Rafida sits about 2055 m above sea level (SRTM open elevation data), which means the roof is first checked for the way water and sun behave at that height rather than for a generic flat-roof setup. The technician looks at the surface for cracks, lifted edges, ponding spots and old membrane that has gone brittle, because these are the points where water is most likely to find its way in. Liquid roof waterproofing is commonly quoted at SAR 8–25 per m², and bitumen membrane at SAR 15–35 per m², so the first check also confirms which of these suits the existing surface and what the rough cost range looks like for the area being treated.

Some decisions are left to the site visit, because they depend on what is actually found on the roof. The number of square metres, the length of any cracks that need crack injection (quoted at SAR 40–120 per metre), and whether a spray foam or XPS board layer is needed underneath all depend on the measured area and the condition of the slab. Where a roof drains into a tank or connects to a basement, the technician also checks whether related work such as tank internal coating (SAR 25–60 per m²) or basement waterproofing (SAR 50–150 per m²) should be priced separately. Nothing in this section should be read as a final quote; the on-site measurement and inspection set the scope.

Information that helps the technician is simple and worth preparing in advance. Tell the team which parts of the roof leak during heavy rain, whether a previous coating was applied and what it was, and whether the roof is accessible for work without disturbing occupants below. Photos of ceiling stains and any visible cracks are useful, as are the dimensions of the roof and the location of drains, parapets and rooftop fixtures. With this information, the visit can focus on the real problem areas, the scope can be agreed clearly, and the waterproofing can be done with the least disruption to the household.

The aim is to locate the cause with instruments first, so any opening is limited to one point.

Signs that call for roof waterproofing

These are the signs most often linked to roof waterproofing:

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

Causes we see in the field

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

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.
