Before we start: what we know about Ahad Rafida

Team note on Ahad Rafida: 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.. Main roads in or near Ahad Rafida: King Khalid Road.

The centre of Ahad Rafida sits about 2055 m above sea level (SRTM open elevation data).

The first thing checked on a villa roof in Ahad Rafida is the altitude, because the centre of Ahad Rafida sits about 2055 m above sea level (SRTM open elevation data). At that height the sun and temperature swings are strong, so the technician looks at how the roof has been exposed over time and whether the existing layers are holding heat in the rooms below. Before any product is discussed, the roof surface is walked and the parapets, drains and upstand edges are inspected, since these are where water usually finds its way in. The choice between a liquid roof waterproofing system priced at SAR 8–25 per m², a bitumen membrane at SAR 15–35 per m², or XPS boards at SAR 12–30 per m² depends on what the roof already has and how it is used, so the check starts with the existing build-up rather than the product list.

Several things are left to the site visit because they cannot be judged from a description. The technician will measure the actual roof area, confirm whether the surface is flat or sloped, and note any cracks that may need crack injection, which is priced at SAR 40–120 per metre. Where a spray foam option at SAR 20–45 per m² is considered, the technician checks the substrate, the condition of the surface and access for the equipment. If the villa also has a rooftop water tank, its condition and the need for a tank internal coating at SAR 25–60 per m² are assessed on the spot, as are any signs of damp in the walls below the roof line. None of these points can be settled from a distance, so the final scope is confirmed only after the visit.

To help the technician arrive prepared, the homeowner can note when leaks or damp patches first appeared, which rooms are most affected and whether the problem worsens after rain or heat. Clear access to the roof, the position of the water tank and any previous repair records are all useful. Photographs of the ceilings and the roof surface taken from above can speed up the first assessment. It also helps to say whether the roof is used for storage, a terrace or water tanks, as this affects which system suits the site. With this information in hand, the technician can plan the visit efficiently and give a clearer picture of the work needed on the villa roof.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.
