Roof waterproofing in Ahad Rafida: the local context

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).

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), so the roof is exposed to strong sun in the warm months and to rain when the season arrives. Before summer or the rain season, the first check is the roof surface itself: looking for cracks, lifted edges, ponding areas and any old coating that has started to peel. Cracks are priced separately, with crack injection at SAR 40–120 per m, so the technician will want to see how many linear metres are involved before any area work is quoted.

Several things cannot be settled from a description and are left to the site visit. The technician needs to walk the roof, check the slope and drainage outlets, and see whether the existing layer is still bonded or has to be removed. The choice between liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m² and XPS boards at SAR 12–30 per m² depends on the surface condition, access and how the roof is used. Quotes for any area should be read as ranges until the measured area and the state of the substrate are confirmed on site.

To help the technician prepare, the homeowner can note when water was last seen inside the top floor, where stains appear after rain, and whether any tank sits on the roof. Tank internal coating, priced at SAR 25–60 per m², is a separate job and should be flagged early if it is also needed. Bathrooms on the upper level, if they sit against the roof edge, can be listed too, since bathroom waterproofing is charged at SAR 15–40 per m². Clear photographs of the roof and any leak marks, plus rough measurements, will let the technician arrive ready to work and give a more accurate picture before summer or the rains begin.

Checks before summer and before the rain season catch problems while they are still small.
